Setting Avid ProTools up for Mixing

We thought it would be good to review options for configuring an effective and inspiring mixing environment. We’ll pull together certain techniques that the Pro’s use, consider new ways to utilize some tools, and explore additional Pro Tools features that can significantly enhance the mixing process.

Anyone that has mixed before has seen how beefing up a system can facilitate taking on larger, more complex projects. Nowhere is this more imperative than when mixing. You just can’t get enough of certain items:

  • Control surface features. Mixing is all about making repeated control adjustments until you’ve gotten parameters just right. How do you make these adjustments? Perhaps largely using the graphical editing tools we explored last week, but everything else you do involves setting linear fader levels, rotary pot positions, and other types of controls. Control surfaces make these actions considerably easier, so it won’t be a surprise if you use these features more when mixing that at any other stage of the production process.

  • Screen real estate. With or without a control surface, mixing benefits from as much display capacity as possible. Besides having access to both the Mix and Edit windows, you’ll often want to show multiple plug-ins as well as other windows. Larger monitors are always good, but a second display is even better. 

  • Processing power and RAM. The amount of number crunching going on within a mix can be staggering. Unless you’re making minimal use of signal processing, faster multi-processor or multi-core hosts for native systems—or additional DSP cards with an HD rig—will enable you to manage far more involved mixes. Likewise, additional RAM will boost general performance and enable the use of more plug-ins, particularly processor hogs like convolution reverbs.

  • Plug-ins. Of course, all of this processing power won’t help if you don’t have much in the way of plug-ins. The standard suite of Pro Tools plug-ins is a nice start, but you’ve already seen how additional Avid as well as third-party products can dramatically enhance your capabilities. For mixing, you may want to start by looking at additional ambience and effects processors, since these are not the strongest elements of the basic Pro Tools collection.

Although generally speaking most mixing beginners use systems with a single monitor with and without a basic control surface, you can imagine that display options can be much more dramatic with expanded systems. However, if you are fortunate enough to have two monitors and do not have a control surface, you’ll likely want to dedicate one monitor for the Mix window and the other for the Edit window.  If you prefer to do most of your work using the Edit window, you might toggle between Edit and Mix on your main monitor and reserve the second for plug-ins as well as other frequently used windows (Memory Locations, Automation, etc.). With two monitors and a control surface, there’s rarely any reason to access the Mix window. Maximize the Edit window on the main monitor, and use the second as described above.

When using a single monitor, how can you optimize the display? Consider these options for the Edit window:

  • View the left (tracks/groups) column. Though you can use Groups List Keyboard Focus mode (introduced in the next topic) to enable and disable groups, you’ll miss some nice features without access to the Groups List.

  • Hide the Clips List. Yes, there are commands in the Clips List popup menu you might need when mixing, but some have shortcut equivalents, and much of the time these are not necessary.

  • Select inserts, sends, and I/O view options. The I/O column allows you to bring up Output windows and use quick shortcuts to access automation playlists, so this is a good option when you’re mixing primarily with the Edit window.

  • Show the Automation and Memory Location windows. These may be accessed frequently, so consider dedicating a typical area for them.

  • Hide the Transport window. At this stage, it just gets in the way, and you can display transport controls in the main Edit window toolbar and/or set the numeric keypad to Transport Mode for control of everything you need.

  • View one plug-in at a time. Though it can be really convenient to have more than one plug-in window on screen, they will quickly obscure the rest of the session. Alternatively, use the commands introduced below to facilitate working with multiple floating windows.

Your base display might look like this:

However, it is sometimes very useful to include multiple floating windows in your screen layout. For example, you might want to display several plug-in windows in order to compare EQ settings on various channels, or utilize a series of output windows to provide mixer-like functionality while maintaining the basic Edit window perspective. Some users don’t bother with such configurations, since it takes a bit of effort to open and close all of the windows. However, there are a couple of newer Pro Tools features that greatly facilitate these scenarios:

  • Hide floating windows. The command Window > Hide All Floating Windows makes it much easier to utilize multiple windows. Rather than closing and reopening floating windows manually—a minor but annoying hassle—you can simply hide them temporarily. You can also use the shortcut Command-Option-Control+W (Mac OS) or Control-Alt-Start+W (Windows).

  • Create custom Window Configurations. A handy part of the Pro Tools feature set is the ability to name, store, and recall the configuration of windows in a session as well as the view options of the primary windows.

Color coding is the type of feature that might seem trivial at first glance. However, it can really enhance the usability of sessions by providing an additional dimension of feedback that helps you differentiate repeated elements with similar features.

Three aspects of the Edit and Mix window displays can be customized with color coding preferences:

  • Color bars that appear in several locations

    • above and below each channel strip in the Mix window.

    • to the left of each track in the Edit window track area.

    • to the left of each track name in the Tracks List.

    • to the left of each group name in the Groups List.

  • Track area display in the Edit window

    • clip shading in Blocks or Waveform views.

    • waveform color when viewing automation playlists.

  • Shading between markers in the Markers ruler.

Note that of these options only the Track Color view affects the Mix window display.

Color coding selections are made in the Display preferences tab. Track Color Coding settings apply to all color bars, and Clip Color Coding settings determine clip and waveform shading. Marker ruler colors are enabled via the first checkbox, or when choosing the Marker Locations option for clips.

How important is the brightness and contrast of the Pro Tools interface? Perhaps more than you’d think. Consider the dramatic changes made to the graphical user interface way back when version 8 was released:

A session opened in Pro Tools 7.4

The same session as of Pro Tools 8.

The difference is not subtle. If you’re like most people, you either love the updated interface… or can’t stand it! At that time, many who preferred the “classic” version liked the bright display and contrast that could make it easier to differentiate on-screen elements. Some who preferred the revised version found it more comfortable for viewing, especially during long sessions.

What do you think? Regardless, there are additional display options that allow you to modify the standard grey background if you find it unappealing. The Color Palette window can be used to customize interface colors, and in particular alter the shading of channel strips.

The Brightness slider can make a big difference for background contrast. You also might want to experiment with the Apply to Channel Strip button shown above, along with the Saturation slider, to shade channel backgrounds according to the active color coding preference.

If you’re consistently well organized, carefully manage your assets from the very first tracks and clips in a session onwards, and follow recommended procedures for recording, overdubbing, and editing, you can skip this section. On second thought, even the most rigorous and diligent engineers should still read on. This is a good time to review various ways to prepare a session for mixing, and there’s a good chance you haven’t tended to at least a couple. Furthermore, you may inherit a project from another engineer and find yourself forced to deal with someone’s mess, or get a gig remixing an existing record. Despite your best intentions, you nonetheless may need to deal with the following elements of a session prior to mixing:

  • Rename tracks. Don’t be surprised when you’re hired to mix a session and track names are obscure and unrecognizable. Restrict names to 8 characters or fewer so that certain control surface LED scribble strips won’t truncate them.

  • Add markers. The complete song form should be clearly and precisely outlined so that every major transition is easily located. This will also facilitate selecting sections of a song in order to create snapshot automation.

  • Create selection presets. It’s also handy to define preset selections for frequently accessed sections of a song.

  • Construct a beat map. Even if you didn’t do this for editing, a beat map can also come in handy when mixing for techniques such as synchronizing plug-ins with the performance.

  • Create display presets. Memory locations can also be used to store detailed display configurations with customized track show/hide status, height, group enables, zoom settings, and window configurations. For example, you might have a setup for submixing background vocals that includes displaying certain tracks with specific heights and zoom settings. Such presets generally should not have time properties designated. 

  • Define groups. This is a powerful feature that facilitates linking controls on related tracks. We’ll address it in detail in the next topic.


  • Clean up. The track area in particular can get increasingly messier as a production progresses, and is often at its worst when mixing commences. We’ll discuss how to approach such problems on the next page.

  • Print Instrument tracks. You’ll probably need as much processing power as possible for plug-ins when mixing. Virtual instruments typically demand an inordinate percentage of available resources, so you should consider bouncing them to Audio tracks. 

In theory, your tracks and edits will be clean as a whistle when it’s time to mix. In reality, that’s not always the case. Although you’ve presumably sliced and diced the playlists already, some rough edges may remain. Try to address the following prior to mixing:

  • Trim tops and tails. Although it’s possible to keep your clips intact and automate mutes in order to control where they begin and end, it’s a much better idea to trim back clips. You’ll save processing power for more important tasks, and there’s no risk of inaccurate automation timing.

  • Clear other excess. Similarly, you should delete unwanted audio within larger clips. Done properly, your playlists will contain concise clips where tracks play, and will be clear elsewhere.

  • Add fade-ins and -outs. If you trimmed clips as close as possible to the desired audio, it’s possible you’ll need a short fade to smooth the transition. You might want to trim up the entire session and then apply batch fades to make this quick and easy.

  • Check existing edits. It’s possible that some of your crossfades did not end up as clean as you’d like. Verify the integrity of these, or go through a single batch process as above.

  • Consolidate. We discussed consolidating audio two weeks ago, but you sometimes won’t do this until ready to mix. Since consolidating combines all of your edits into a single clip, you may prefer to wait until you’re certain that no further changes will be needed. Consolidation can be useful prior to mixing to reduce the disk access load in sessions with high track counts and edit density. 

When mixing, you’ll often need to make an identical adjustment on multiple tracks simultaneously. Perhaps you want to raise all of the guitar tracks—whether you have 2 or 20—by 3 dB. Or mute the entire drum kit for two beats. Or trim the tails of a set of background vocals. Or… well, do almost anything you’d do on a single track.

There are two ways to approach these scenarios that don’t involve painstakingly making the exact same moves on each track. Grouping can make your work much easier in all phases of the production process, but especially when mixing.

We’ll look at a variety of considerations pertaining to implementing and using Pro Tools grouping features, including significant new features, enhancements, and changes introduced in recent versions. Complete the reading below before continuing.

General Characteristics of Groups

Fundamentally, grouping seems like a simple enough concept. However, a closer look will reveal some fairly sophisticated and versatile capabilities. We’ll start by identifying the general characteristics of Pro Tools grouping features before exploring how they work in your sessions:

  • Recent versions do more. Grouping in older Pro Tools versions was a useful but basic feature. It’s now both useful and extremely powerful. Noteworthy enhancements include:

    • more groups (104, in 4 banks of 26)

    • enhanced Create Group dialog with additional options

      As of version 12 the Create Group dialog supports both global as well as individual group attributes.

    • no need to select tracks prior to invoking the New Group command

    • no longer necessary to overwrite existing groups to modify their specifications

    • revised Groups List popup menu

    • ability to specify which controls are grouped

  • Basic grouping and VCA-style grouping are different. When using the functions discussed in this topic, a control change on a grouped control on any track results in the same change to all group members. There’s another option—VCA-style grouping—in which multiple tracks can be controlled by a remote master, but the controls on the individual channels only affect a single track. (Requires either Pro Tools HD or version 12 or higher software.)

  • Fader (or other control) levels on grouped tracks maintain the same relative positions when adjusted. For example, if you raise a fader on one group member such that others top out, the relative positions are restored when you lower the levels.

  • Groups can be specified for edit functions, mix controls, or both. An Edit group only affects specific edit functions:
    • track view
    • track height

    • track timebase

    • editing functions such as selecting or trimming multiple tracks

    • automation functions such as inserting or modifying data on multiple tracks

 Mix groups can include fader, mute, and other controls (many more with Pro Tools HD). Edit groups do not include these controls, even when utilizing Edit window channel controls.
  • Groups can also be nested. You can define and use multiple groups with overlapping members. The Group ID for any channel appearing in two or more active groups is displayed in upper case.

Here, we’ll quickly review the steps required to create a Group in ProTools.

  1. Use any of the following methods to access the Create Group dialog:

    1. Invoke the command from the Track menu.


    2. Invoke the command from the Mix Groups list or Edit Groups list popup menu.


    3. Use the shortcut Command+G (Mac OS) or Control+G (Windows)


      NOTE: With previous versions of Pro Tools, it was necessary to select all tracks to be grouped prior to invoking the New Group command. This is (conveniently) no longer the case.

  1. Enter an appropriate name and select an ID.

    NOTE: You don’t have to stick with the default consecutive IDs for your groups. It can be helpful to use letters that relate to the group members (d for drums, for example), or come up with a standard configuration you’ll remember in all of your sessions. By doing so, you can facilitate enabling and disabling groups using Groups List Keyboard Focus (described below).

  2. Select the group type. If you’re not sure whether you’ll need the group for edit or mix functions, select both types; you can always modify this later.

  3. Select the attributes that will be linked on Mix group tracks (in addition to the fader level and automation status, which are always linked).

     NOTE: In version 12 and higher, you can also assign the group to an available VCA Master track.
  4. Select the tracks that will be members of the group, using one or more of the following methods: 

    1. To add selected tracks to the group member list, click on Add.

    2. To add selected tracks to the group member list in place of any members currently in the list, click on Replace.

    3. To add tracks from the Available tracks list, select one or more in the list, then click on Add >>.

    NOTE: Press A on the keyboard to add tracks selected in the Available list.
6. Click ok

It’s not uncommon for you to want to modify characteristics of a group. For example, you might record new tracks that are consistent with an existing group, or find that you’d rather not have an Edit group also link track controls. In the past, you’d have to create a new group and overwrite the previous one to effectively modify it. That’s not necessary anymore:

  1. Access the Modify Groups dialog using any of the following methods:

    1. Select Modify Groups in the Edit Groups List or Mix Groups List popup menu.

    2. In the Mix window, click on a track’s Group ID Indicator and select Modify in the popup menu.

    3. Right-click or click and hold on the group name in the Edit Groups List or Mix Groups List, then select Modify in the popup menu. 

  2. Set the group parameters as you would when creating a new group, starting with the group ID.

    1. The Remove button in the Modify Groups dialog provides an easy means for removing one or more tracks from the current group members.

    2. The handy—but dangerous—All group (discussed shortly) can be modified to make it somewhat less dangerous by restricting it to only act as an Edit or Mix group.

Two of the methods for modifying groups also provide a means for deleting a designated group:

  1. In the Mix window, click on a track’s Group ID Indicator and select Delete in the popup menu.

  2. Right-click or click and hold on the group name in the Edit Groups List or Mix Groups List, then select Delete in the popup menu.

You can also delete all currently active groups with the aptly named Delete Active Groups command in the Edit Groups List or Mix Groups List popup.

NOTE: Deleting groups is not undoable, so be certain you really want to do this. Don’t worry; you’ll be reminded. Also keep in mind that deleting groups leaves the actual tracks intact.

Don’t discount the possibility that a grouped pair of mono tracks might occasionally be more effective than the typical stereo configuration. It’s true that a single stereo track is usually best for two-channel sources such as virtual instruments or stereo miking. However, you’ll sometimes want to treat one side of the pair differently than the other, like using a different plug-in on the left and right channels. In this case, it might be convenient to simply work with mono tracks but group them to easily adjust their general control settings.

In this section, we’ll explore a variety of aspects related to using channel inserts in Pro Tools sessions. We’ll start by considering several general insert issues, including the potential for misusing plug-ins, insert signal flow in applicable tracks, and the distinctions between multi-mono and multi-channel formats. We’ll review basic methods for instantiating inserts, and throw in a few new tricks for simultaneously adding or deleting multiple inserts, as well as moving and copying them. We’ll look at several options for organizing plug-in menu listings, including basic preferences, custom plug-in favorites, and default EQ and compressor settings. We’ll identify the performance issues relevant to heavy use of plug-ins, and suggest appropriate settings for optimizing plug-in capabilities in mix sessions. We’ll revisit the concept of plug-in latency discussed earlier this week, and see how to mitigate the potential problems of phase cancellation. Finally, we’ll survey a variety of specific techniques that will be helpful when utilizing inserts. Complete the reading below, and then we’ll get started.

Inserts and real-time plug-ins are not equivalent. It’s easy to think of these as identical, since all real-time plug-ins are instantiated as channel inserts. However, hardware I/O channels can also be utilized for inserts, and this has nothing to do with internal signal processing. We’ll be dealing with plug-ins almost exclusively here and will use the terms somewhat interchangeably, but keep in mind that there is an alternative.

Scroll past the plug-in submenu when instantiating an insert to access another submenu with hardware I/O options.

If your audio interface only supports two inputs and outputs, it won’t be possible to use hardware inserts. (You’d need at least one unused input and output channel, and the main stereo monitor outputs would preempt any others.) 

When a plug-in is inserted in a channel, it interrupts the normal signal flow and routes audio through the plug-in software. When an I/O channel is inserted in the signal flow, audio is routed to the designated audio interface output channel, through an external device, and back through the corresponding audio interface input channel.

Messing around with signal processing can be one of the most enjoyable aspects of production. But beware: just like with anything else, too much of a good thing can quickly cease being so good. Novice engineers often fall into one or more of these classic traps: 

  • Overprocessing. It often seems like it’s easier to crank up the controls of an on-screen device as opposed to actual hardware. There’s something about turning a pot all the way up that breeds caution more than clicking and dragging.

  • Too many plug-ins. There’s rarely a good reason to use three, four, or even five inserts across the board. Nonetheless, some engineers appear to believe that more is better. It’s not.

  • Poor gain staging. In theory plug-ins can be overloaded, and unlike classic analog gear they won’t sound good when doing so. Fortunately, the 32-bit floating point processing used by AAX plug-ins provides essentially unlimited headroom, so this is no longer a critical issue. Still, I’d pay attention to gain staging—at some point, even if only with regards to hardware inputs and outputs, you’ll have to stay within proper operating limits.

The channel signal flow for Audio and other track types is not complex compared to traditional consoles, but you still need to be aware of how it works. In Audio, Auxiliary, and Instrument tracks, inserts are always pre-fader and appear in series beginning with Insert A. Keep in mind the order of insert slots when setting up signal processing. If, for example, you want your EQ to follow a compressor, you don’t want it placed in the first slot. 

Five inserts are shown here, but all Pro Tools audio-based tracks provide a second bank with five more.

Once instantiated, insert order can usually—but not always—be changed. If you invoke a plug-in with, say, a mono input and stereo output, it cannot be placed ahead of a plug-in with a mono input.

You’ve probably noticed the options of both of multi-mono and multi-channel formats when instantiating plug-ins on stereo tracks. What’s the difference?

  • Multi-mono plug-ins are linked pairs (or larger configurations with surround mixing) of independent processors. The controls can also be unlinked to provide independent adjustment of each channel.

  • Multi-channel plug-ins act like single processors regardless of their input and output configuration. Often, the processing itself is linked. For example, reverb effects may be based on a complex combination of both input channels, and multi-channel dynamics tools generally link gain reduction in both channels to be triggered by an input on either. 

You’re already familiar with how to instantiate a plug-in insert using the ten Insert Selector buttons on each track in the Mix and Edit windows. We’ve also demonstrated how the Plug-in and Insert Position Selector buttons in plug-in windows can be used for these purposes.

Within a channel, just click on the plug-in Insert selector for the desired slot.

Within a plug-in window, first select the insert slot.

Then instantiate a plug-in.

The same controls are used to remove instantiated plug-ins.

no insert

These methods can be extended to instantiate or remove multiple plug-ins simultaneously:

  1. To instantiate or remove the same plug-in on every visible track, press and hold the Option key (Mac OS) or Alt key (Windows) while instantiating (or removing) a plug-in.

    NOTE: Why doesn’t this technique apply to the second channel? It’s a stereo track, and only plug-ins with the same format will be affected. Note that you can use the Plug-in Selector on any track to both instantiate and remove.

  1. To instantiate or remove the same plug-in on every selected track, press and hold Option-Shift (Mac OS) or Alt-Shift (Windows) while instantiating (or removing) a plug-in.

  2. To move an insert to a different position, click and drag the insert to the desired slot. You can move an insert to a different slot on the same channel or to a different channel, but the format must match. If you drag the insert to a slot that already contains one, it is replaced.

  3. To copy a plug-in to a different slot, press and hold the Option key (Mac OS) or Alt key (Windows) while dragging the plug-in to that slot. The duplicate plug-in will have identical settings as well as any applicable plug-in automation.

As you build up your plug-in collection, the process of instantiating can get awkward. Popup menus become unwieldy when the number of items is lengthy, and it’s easy to miss your target when scrolling through multiple submenus. Fortunately, there are a few simple Pro Tools features that can improve the process:

  1. Menu Organization. You can set the preference that determines how the plug-in menu is organized to best suit your needs.

    Menu Organization

    The Flat List is not going to help matters much unless you absolutely despise popup submenus:

    With the Flat List display, the popup length may exceed your screen height!

    Organizing by Category is the default option:

    Organizing by Manufacturer might work for you, but in many cases you’ll end up with a submenu imbalance that won’t make the process any easier:

    Note that the Avid submenu includes Melodyne and Reason, since the plug-in itself is just the ReWire link to external software.

    The Category and Manufacturer option simply provides both organization systems, which presumably is useful under certain circumstances…

  2. Plug-in favorites. If the plug-in menu organization preferences leave you wanting easier options, fear not—there are two other handy features. You can add your most frequently used selections to the root level of the plug-in submenu by pressing and holding the Command key (Mac OS) or Control key (Windows) while selecting the desired favorite.

  3. Default EQ and Dynamics. Even more convenient is the option to place default EQ and dynamic plug-ins as the first two choices in the root level of the insert popup menu, making them incredibly easy to instantiate. Set the default choices in the Mixing preferences tab.

    You can choose any installed EQ and dynamics plug-ins for default choices.

    Default processors are always the first selections in the insert pop-up menu.

Many of the issues we considered for recording are also applicable to the mixing process:

  • Optimize the host computer’s operating system, and disable unnecessary features.

  • Refrain from running other applications in the background, unless they are related to your project (i.e. external VIs such as Reason).

  • Prior to Pro Tools 11, set the Pro Tools CPU Usage Limit as high as possible, while allowing sufficient resources for basic OS tasks such as screen redraws as well as necessary background applications. (Accessed via the Playback Engine dialog.)

However, certain settings that are appropriate for recording must be approached differently for mixing:
  • Host Processors. Prior to Pro Tools 11, with multiprocessor and multi-core hosts you can dedicate some or all of the additional CPU power to real-time plug-ins. This is not necessary when recording, since you’ll generally want to minimize plug-in use to avoid monitoring latency. Mixing is an entirely different story. Try to reserve as much processing power for native plug-ins as is feasible without sacrificing OS performance or automation accuracy. Typically, you’ll reserve at least one processor for system functions, but individual scenarios may vary.

  • Hardware Buffer. You also learned that a small Hardware Buffer size helps minimize monitoring latency. But a larger buffer becomes essential as signal processing demands increase, so when mixing you’ll want it set as high as possible. Since there’s a possibility of inconsistent automation and MIDI timing at higher settings, you should experiment with your system to identify the optimal mix configuration.

    The Pro Tools 10 Playback Engine dialog. Note that Hardware Buffer and RTAS Processor options vary based on your host computer and Pro Tools hardware.

    The version 12 Playback Engine dialog.

    Consider displaying the System Usage window to get an idea of how much CPU power is being used:

    Session with 25 EQ plug-ins

    Session with 25 EQ and 25 compressor plug-ins

    Session with 25 EQ, 25 compressor, and 25 reverb plug-ins

    At some point, the CPU might not be able to handle excessive signal processing. If the buffer size is already maxed out, the only solution is to reduce the number of plug-ins (assuming we’re fond of the tracks and can’t afford a new computer!).

Also note that bypassed plug-ins use as much CPU power as when processing signals. If you have no immediate use for certain plug-ins but don’t want to remove them from a session, it’s better to deactivate rather than bypass. (Control settings and automation you may utilize later are preserved.) Command-Control-click (Mac OS) or Control-Start-click (Windows) on a plug-in (or hardware) insert to deactivate or reactivate it.

First, how can you tell if the processing on a channel is causing latency? Phase cancellation might not be apparent if the volume level is low, so it’s a good idea to check the channel status directly. To do this in Pro Tools 10, just Command-click (Mac OS) or Control-click (Windows) on the Audio Volume indicator below any fader in the Mix window to cycle through its three displays (fader level, peak track level, and total track latency). If using version 11 or later, the Audio Volume indicator is the left display below the fader, and you can toggle between fader level and latency.

Track latency can also be viewed when delay compensation (discussed below) is active by selecting the Delay Compensation option in the Mix Window View.

Total track latency displayed in Pro Tools 10.

Latency displayed in Pro Tools 12.

Latency is measured in samples, so in the example above the delay will be approximately 1.5 milliseconds assuming a sample rate of 44.1 kHz (64 ÷ 44,100). Depending upon the plug-ins being used, latency can be significant. In the next example, we’ll activate multiple inserts on a channel. Of the five inserts, all but the first introduce latency. Note how the total latency increases as we activate the plug-ins one-by-one.

Fortunately, this is readily mitigated. Although there are a few methods for dealing with latency, the easiest is to utilize Automatic Delay Compensation. ADC does all of the work for you, adjusting every track’s total delay as needed and updating these settings whenever plug-in instances are modified. It also compensates for the delays associated with busses and sends. It’s theoretically possible you’ll still need to use manual adjustments on occasion, since there’s a limit to the total delay compensation available. However, this will rarely—if ever—be the case, so delay compensation will usually be quick and easy. Here’s how it works:

If you want to use an old-school solution for latency, the following should be a workable solution:

  1. Identify the channels that may need intervention, based on the scenarios we’ve discussed.

  2. Identify the total latency on each channel, and note which channel has the highest latency.

  3. Instantiate the TimeAdjuster plug-in on each affected channel other than the channel with the maximum latency. (Use the small, medium, or long depending upon the amount of correction needed.)

  4. Set the TimeAdjuster delay on each channel so that the total latency matches the delay on the channel with the maximum latency.

  5. Don’t forget to update the TimeAdjuster plug-in settings if you make a change in plug-in usage that alters the latency on the affected tracks.

This may sound like a hassle, and in fact it’s not the most enjoyable part of mixing. But you shouldn’t have too many instances that require intervention, so won’t need to spend a lot of time dealing with latency. Here’s the basic process in the same session:

Command-Option-click (Mac OS) or Control-Alt-click (Windows) on any level display to toggle to the delay time for all tracks. After we add the first adjustment, we can Option-click and drag (Mac; Alt using Windows) on the plug-in nameplate to duplicate it on another track.

Note that the above example was made using Pro Tools 10; the process should be equivalent in version 11, but the TimeAdjuster plug-in doesn’t seem to affect the latency indicator!

Top-10 Tips to get a Professional Sounding Mix

In today’s tech world, everyone that has a computer is expected to produce expert quality projects.  This is somewhat easy when one needs to create a PowerPoint presentation or a Word Document, but it is not so easy when the final product requires unique skills.

It takes years to get to the point to create studio quality albums, but there are key areas to focus on that can make a night and day difference in the sound quality of the final output.  I put together a top-10 list that can help get you thinking like a Music Engineer/Producer:

1. Check the session over before you start

Make sure you have all the parts, esp. if mixing for someone else. You would be surprised how often a part gets forgotten (Check the rough mix too!) & consolidate the files if you can – it makes it easier to “see” what’s going on in a big session, and psychologically it looks neater! It’s a small thing – but when zoomed “out” you will be able to see where everything is, rather than a mass of edits, which obscure the waveforms.

2. Get the timing right

Especially drums –very important that it’s tight if lots of parts are layered. If there is some unintended “Flaming” going on (i.e. transients of 2 snares that don’t start at the same place, or worse kicks! It can sound messy) In the case of kick drums it can make it sound weaker too, which is very often the opposite of why it’s layered with different sounds.

3. Print Virtual Instruments can be useful

Not everything benefits from this, BUT drums do, and it will help you to see if there is any issues with timing. It also stops you fiddling with the samples and sounds, and concentrate on the mix! As it’s a hassle to reprint. It also frees up system resources, if there is a lot of virtual instruments it can suck a lot of computing power, even with today’s systems, and you will be struggling to have enough power to do the mix.

4. Listen Quietly

It will help if you are in a less than ideal acoustic space (if the room is not acoustically treated, it will get worse with more volume!) I have worked in a few weird sounding places! It really helps when you keep the volume down – the more you crank it, the more any issues with acoustics (or lack of) will show up and you will make bad decisions.

5. Subs can be useful

But only if you have quite a large room (Need 12-15 feet in at least one dimension) and your neighbors will not thank you! (Sub’s tend to throw out in all directions, so it often sounds louder than it actually is, away from the speakers)

6. Listen in Mono

It’s hard to do, but very good for balance (check out other mixes, see if you can listen to them in mono – see where things “Sit” and try and work it into your balance). You might find this teaches you more than you think.

7. Be clear on what you – or the client wants

If you are mixing for someone else – ask what they want! It sounds simple but it’s not good making a “banging” mix with hard drums if they want it “Classic & Warm!” LOL ☺ & ask them what they don’t like, and see if you can fix it (there’s a challenge). Be aware also that they may not KNOW what they want, so it can be a tough job to find the right direction for a mix approach, and might take a couple of attempts, but don’t give up! listen to the rough mix, even if it’s bad, it can give a good overview of what the track is about, and also any problems (Can’t hear the vocals, too soft/hard EQ etc….)

8. Take Regular breaks

Ear fatigue is real, and just because you are young, you are not immune! Sometimes it’s hard – but even a 5-minute tea stop can do wonders for your perspective. And if you are the engineer – if you’re old enough to, please DON’T DRINK ALCOHOL while you work – it changes your perception (for the worse) and you will find yourself questioning things, as it dulls your high end.

9. Watch your levels

Start with the faders down if you can (like on a desk) and build a rough balance – if you have difficulty balancing things (can’t get it loud enough, or the fader is at the bottom, and it’s too loud or disappears) you may need to adjust your levels for better gain staging on each part – remember headroom in channels is GOOD – and the more level in each channel, the harder it will be to build a good mix before everything goes red, and in a DAW that’s mostly bad!

10. Reference other material

Reference other material, and level match it – this is very useful for seeing where you are with the tone (EQ) of the mix – and don’t forget to always print an “Unlimited” master pass, that is one without the limiter if you have cranked it hard – mix compression is ok, as long as you like it.
Have fun with it – and if you are working in a DAW (digital audio workstation) you can always come back fresh and go again!

Why German Producer TheFatRat Walks From Label

Right now, all over the world, boys and girls are hunched excitedly over laptops, unzipping fresh cracked versions of Ableton or FL Studio or Reason, their fingers itching to crank out the next festival anthem. Their minds are whirring with the possibilities. What if they get one million plays on Soundcloud? What if Tiesto likes their track? What if Ultra Music called them with a contract?

It would all be so cool, but one German independent producer wants them to ask themselves another thing. If Ultra Music did come calling, what if they said “no?”

“There are incredible opportunities today for artists,” Christian Büttner says. He’s been making music professionally for 12 years, mostly as a ghost producer, but in the last 18 months, he’s switched his focus to building under his own moniker, TheFatRat

Even though he recently took time off to be with his newborn daughter, he’s amassed more than 183,000 followers on Soundcloud and tens of millions of plays. Now that baby girl is old enough to travel, he’s setting up his first North American tour.

He’s making a career in music work, and he’s doing it all without a deal.

“The all-mighty internet is full of blogs, communities, YouTube channels, forums and a million more things,” Büttner says. “They all can help you to get your music heard, but it’s often difficult for big record labels to use those opportunities.”

Büttner has learned to leverage these sources without the trouble of red-tape and licensing complications. If a 15-year-old boy with a wildly successful YouTube gaming channel wants to use his song, The Fat Rat can give the green light without any hang-ups. Deals like that expose his wildly energetic and genre-blending electro to millions of viewers in an instant. He’s also free to sell his music to app and game developers, and when he strikes such deals, he reaps 100 percent of the profits.

And that brings up another point of contention. Artists who are signed to labels barely see revenue from Spotify or other streaming services, mostly because of contractual fine print. Büttner has learned to be a shrewd business man. These labels are looking out for their bottom line, not his baby girl.

“In some of the deals that were offered to me, I had a base split of 25 percent,” Büttner explains. “When I did the math, I found out that I would effectively end up with not even 7.5 percent of the worldwide streaming revenue. When you sign such a deal you have to generate 130 million plays to make the same money as an independent artist with 10 million plays.”

He also advises independents to take the time to connect with their audience on social media, comment sections, whatever way they can. Without a label to answer to, your fans run the show, and a relationship with them is what makes or breaks your career.

“You want to create an emotional connection with your audience, and you can connect much better to people if you listen to them,” he says. “That way you learn what they are interested in and where exactly you can reach them.”

The independent life ain’t for everyone. It takes a lot of finesse to handle a label-less career. It takes incredible self-motivation and determination. It takes strategy and acumen, and not least of all skills and creative vision. Your first taste of success is addictive, but even as things get better, they don’t necessarily get easier.

Büttner says one of his greatest hurdles is staying focused. He’s an enthusiastic guy. He wants to stay open to as many opportunities as possible, but you’ve got to learn to draw the line somewhere, choose the projects and opportunities that best align with his professional and personal goals as well as his creative voice. Still, if you’ve got the chops, the time and money management skills, and the attention span to handle the ups and downs, it’s a creative lifestyle unlike any other.

“(It’s) creative freedom,” he says. “It’s such an amazing feeling when you sit in your studio, freaking out to the song that you are creating while you can be 100% sure that the song will be released and your fans will hear it. And you don’t have to explain to the whole record company why you are doing a trap song with full orchestra while your last song was chiptune mixed with glitch hop.”

It’s not that TheFatRat would never sign a deal. He just has to be sure it’s the right one. He’s come too far to just hand over his life, and with a big tour looming and growing opportunities on the rise, it’s hard to imagine if that deal will come. There really is no clear road to success for an independent artist. You’ve got to figure it out for yourself, take a page from Jimminy Cricket and let your conscience be your guide. Büttner is doing a good job, but even he says to take his own advice with a grain of salt.

“Don’t look too much on what others do and what is considered ‘best practice,’” he says. “Instead, ask yourself the basic question, ‘who might enjoy my music, and how do I reach those people?’ You’ll probably come up with answers that you never thought of before – and more than anything else, focus on your music.”

Album Sales Sink to Historic Lows — But People Are Listening More Than Ever

It’s the worst year (so far) for music sales since the 1991 debut of SoundScan (now Nielsen Music). Album sales, including track-equivalent albums (TEA, whereby 10 track sales equal one album unit) are down 16.9 percent in the rst half of this year. But sales figures no longer tell the whole story of the record business.

First, let’s bottom-line those disappearing sales. Album units overall fell 13.6 percent, with 100.3 million total sales. The compact disc continued to crumble, losing 11.6 percent and moving 50 million. Digital album sales fell to 43.8 million, from 53.7 million in the first half of last year.

Vinyl sales continued to move up and to the right, growing 11.4 percent, to 6.2 million. New album releases have been most affected by the continued contraction, falling 20.2 percent overall, to 44.1 million units. Catalog albums fell “just” 7.7 percent, to 56.2 million.

Track sales also dropped, to 404.3 million units from 531.6 million units. Current track sales are leading the descent; songs released in the last 18 months saw sales fall nearly 40 percent. Catalog, again, saw a much smaller dip, down 6.4 percent to 236.6 million units.

Listeners streamed 208.9 billion songs (which translates to 139.2 million album units) between January and now (July 6), an increase of 58.7 percent. Of that 208.9 billion, 113.6 billion were audio-only, versus 95.3 billion video streams (defined as a music video view on YouTube, Vevo, Tidal and Apple Music — of which the latter two contribute a very small piece). It’s the first time audio has surpassed lower-paying video streams.

What’s that all mean?

Billboard estimates total U.S. revenue at $1.98 billion so far this year, versus $1.82 billion last year, an corresponding 8.9 percent increase. However, the rate that Billboard uses to estimate the revenue generated by streaming ($0.0063 per song), which is clearly a central part of the revenue estimate, has been disputed as too high by some indie labels.

Drake is clearly the year’s winner so far. The rapper’s newest album, Views, sold 2.61 million total units — 1.3 million album sales; 317,000 track- equivalent albums and 979,000 stream-equivalent albums (SEA, whereby 1,500 streams equal one album unit).

Drake has the year’s best-selling digital album, at 1.4 million units moved. David Bowie’s  Vinyl record, Blackstar, sold nearly 57,000 LPs, making it the year’s best-selling vinyl album.  Flo Rida’s “My House,” with 1.95 million track sales, is the best-selling song of the year and just one of 16 total songs to sell over a million so far (27 had hit that mark by this time last year — six of those had tipped 2 million). The year’s top 200 tracks have scanned 83.8 million units in total.

The most common place for people to purchase albums and songs was, unsurprisingly, at digital retailers, which captured 43.7 percent of the album market (and which, obviously, saw overall sales decline by 18.4 percent, to 43.8 million album units). Surprisingly, “non- traditional” CD retailers, like Amazon and supermarkets, saw an 8.3 percent growth in sales.

Executives that Billboard spoke to at the end of 2015 pointed, in no shock, to streaming as the main culprit in the sales cull, particularly song sales. And streaming is booming.

For the year, total album consumption — which includes TEA, SEA and overall album units — totaled 279.9 million units in the first half of 2016, up 8.9 percent, clearly driven by streaming.

Avid ProTools Music Mixing Myths

Mixing with Avid Pro Tools is just like mixing in any other medium… except when it’s not. This is to say that although the process is in most ways akin to how you’d work with any other storage and signal processing technologies, certain distinctive characteristics of Pro Tools lend themselves to somewhat different approaches than you may have previously encountered—and a few aspects of digital mixing may actually have no precedence in the traditional lexicon of production techniques.

This may sound perfectly reasonable, but entering the world of Pro Tools mixing can quickly become an unexpected and confusing mélange of contradiction, confusion, and outright frustration. Ask 10 engineers how to best go about mixing in the box, and you may get as many differing responses. Worse, it’s likely that much of what you’ll be told will neither be backed up with clear explanations nor hold up to thorough and thoughtful analysis. What’s a budding Pro Tools mixer to do?

The Dark Side of Music Production

The audio industry has always had a murky side to it with regards to matters like sonic quality, preferences about gear, and accepted practices for recording and mixing. Mythology has reigned supreme, and many “truths” are held as gospel for reasons that are largely unclear. An SM-57 is the best snare mic, period. Mixes come out better when monitoring with NS-10s. Analog sounds more natural than digital. Tube mics are superior to all others. Oh, and here’s another for you—the Pro Tools mix bus is inferior to an analog mix bus.

Where do these stories come from? There are no doubt a myriad of sources: the many real, legitimate experiences of intelligent and capable professionals; hasty conclusions based on partial or flawed observations by wide-eyed neophytes hoping to break into the business; a fair amount of marketing hype from audio equipment manufacturers; technical commentary made by individuals with no background to support such statements; years of an industry mindset of some that valued secrecy over sharing for fear of giving away personal tricks and techniques… the list goes on and on. What’s clear from observing these forces at work, and the resulting music industry zeitgeist, is that there’s both good information out there as well as a large number of shady beliefs. For the uninitiated, it’s hard to know what to think.

The whole thing is quite a slippery slope, because the final arbiter is hearing, and there’s no way to measure or compare what different people hear. Furthermore, numerous related factors—often unknown to the listener—might support a different conclusion about the basis of some phenomena that otherwise seems to have a simple explanation. What does it mean if a golden-eared engineer claims to hear a subtle artifact that you do not, and offers an accompanying explanation? It could certainly be that he/she truly has exceptional ears that are “better” (or more finely tuned) than yours, and has built a reasonable analysis from that observation. But it could also mean that he/she  thinks there’s something there or wantsto hear it. It could also be that though there’s something going on, the explanation itself is off base. It’s very easy to fool your ears, and just as easy to jump to shaky conclusions even with the best intent.

It’s tempting to offer up the seemingly sage advice to just trust what you hear rather than blindly accept what you’re told. Sounds reasonable, right? But wait—this is exactly the sort of approach that’s caused such rampant confusion in the first place! When it comes to evaluating audio quality and understanding psychoacoustic phenomena, there’s only one way to develop meaningful conclusions—conduct double-blind tests in neutral, controlled environments, such that neither the listener nor the tester knows which options are being heard at any time. Only under these circumstances can you honestly and legitimately reach conclusions about subtle sonic issues. Otherwise, you’ll unfortunately have to be skeptical about both what you hear as well as what you’re told…

Analog Vs. Digital

One of the hot button issues discussed by people who like to talk about this sort of stuff is the difference between using the “mix bus” in a DAW versus using the summing network in an analog mixer (or, more recently, an external summing device designed strictly for this purpose). Actually, there’s no such thing in the world of digital audio as a hardware device with a common conductor fed by all channels in an analog console; Pro Tools and other DAWs use a mathematical algorithm for accumulating the values of multiple signals feeding a mix. But the algorithm does the same thing, so we’ll succumb to peer pressure and call it a mix bus.

But does a digital mix bus behave the same way as an analog version? Some users are convinced that otherwise identical mixes sound different—and better—when routed through the individual channels of a console or dedicated summing network. Many of these folks blame the DAWs’ mix busses, claiming some sort of inadequacy in the algorithm’s ability to accurately sum audio signals.

As the debate rages on, it can be very difficult to separate fact from fiction, and truth from myth. Since it’s a logistical challenge to create an accurate, unbiased test that compares mixes differing only in their summing methods, you’ll have a hard time researching this issue yourself. Fortunately, it’s possible to distill some simple conclusions amidst all of the chatter:

  • There is no evidence that the summing mechanism in Pro Tools—or any other current professional DAW—degrades or otherwise modifies the quality and character of mixes.

  • There can be audible differences between the sound of a mix created via analog versus digital summing. Depending upon the circumstances and the listener, these differences might be characterized as anything from negligible to significant. Typically, the difference tends towards subtle. In some—but not all—cases, producers and engineers prefer the results derived via analog methods.

If the digital audio mix bus is not responsible, what is? This is not understood definitively, but the explanation may be similar to why many other aspects of analog audio technology have a distinctive sound—the artifacts of analog audio that are inevitable byproducts of storage, transmission, and signal processing often act like sonic enhancers, injecting mixes with subtle flavors that to many sounds good. Interestingly, these manifestations of analog audio essentially reveal fundamental shortcomings of the technology, so it’s ironic that the effects can be pleasing. This is most certainly the primary justification for hanging on to more or less antiquated technologies such as analog tape machines, which at this point in time are a complete hassle to maintain and operate except for the fact that they yield desirable results under the right circumstances.

More specifically, how do listeners describe the differences between digital and analog summing? Some have commented on sonic characteristics involving tone, warmth, and detail. However, these are more likely based on related phenomena such as distortion caused by overdriving analog components. Others have noted differences in the width and depth of the soundstage. The actual foundation of such a distinction is unclear.

What’s the bottom line on how all of this affects you? Honestly, I wouldn’t give any of it a second thought. The fact is, until you can master the many other challenges of production—putting together great songs and arrangements, working with amazing musicians playing beautiful instruments, doing all of this in superior sounding recording environments using quality microphones and preamps, and building mixes with inspired balance, tone and depth—worrying about the nuances of digital vs. analog summing will probably distract you from far more important issues…

Latency Issues When Mixing

In general, latency in digital audio is a time delay observed for data at different locations of a system. Unlike traditional analog setups, in which everything occurs more or less instantaneously, various processes in a digital audio signal chain require small but detectable amounts of time to complete. The primary culprits are tasks such as conversion, disk access, and signal processing. Since each of these can themselves contribute measurable delays in handling audio, latency is cumulative when a signal is subject to multiple processes in series.

If you have ever recorded through a DAW, you have likely dealt with latency in the recording process.  Delays can wreak havoc on a musician monitoring a live performance.  We’ve seen that reducing the size of the hardware buffer and forgoing signal processing on live signals can improve monitoring latency to an acceptable level. Though converter latency cannot be eliminated, using higher sample rates does help.

Latency can also be an issue when mixing. However, in this case the problem isn’t that audio is delayed between disk playback and monitoring. Though this does occur, the only time it could matter is when theamount of latency varies on different channels. As long as latency is the same for all channels, the only repercussion will be a (typically) imperceptible lag when entering playback.

Without inserts, there’s nothing in the signal flow of an Audio track that introduces latency.

Without inserts, there’s nothing in the signal flow of an Audio track that introduces latency.

When latency is the same on multiple tracks, signals arrive at the mix bus simultaneously, and will not interfere with one another.

When latency is the same on multiple tracks, signals arrive at the mix bus simultaneously, and will not interfere with one another.

Having seen that it’s not unusual for audio signal paths to exhibit latency, when is the amount of channel latency different? When mixing, there are two possible scenarios:

    1. DSP plug-ins always introduce a small (and occasionally not so small) amount of latency.

    2. Native plug-ins sometimes introduce latency, if their algorithms utilize look-ahead processing.

    3. Analog hardware inserts always introduce latency due to the conversions necessary to route the signal to the external gear and back to Pro Tools.

    4. Digital hardware inserts sometimes introduce latency, if the external hardware’s algorithms utilize look-ahead processing.

      Different signal processors on channels. In some cases—though not always—latency will be introduced due to channel inserts: 

  1. Different routing used for channels. When sending the output of certain tracks through a bus and subgroup (as we’ll demonstrate next week), those tracks will be slightly delayed.

    In this example, bass signals enter the mix almost a millisecond later than simultaneous snare signals. However, it’s highly unlikely you’ll hear this difference.

Here’s the tricky part: the only time this matters is when the relevant tracks contain in part or completely the same material. This would be the case if:

  1. You’re summing together a processed and unprocessed version of the same signal. This can be a nice technique when you want the sound of (typically) extreme processing but also want to maintain some of the original signal characteristic.

  2. You’re processing a track for an instrument that was recorded with multiple microphones. Let’s say you’re compressing a snare mic. Since the snare sound is also picked up by the overheads and other drum mics, the phase relationship between these tracks changes if the compressor exhibits latency.

    Here, snare signals enter the mix later than the drum overheads. Since the overheads also pick up the snare, phase cancellation can occur.

In these scenarios, the combination of a processed track with latency along with similar tracks without such delays generally results in some sort of phase cancellation.  Phase cancellation is generally not desirable, but all is not lost. Fortunately, it’s possible to compensate for latency so that you can implement any of the above setups without interference problems.

If you’d like to explore the issue of latency further, here’s an informative primer on the topic written by Digidesign: Latency and Delay Compensation with Host-Based Pro Tools Systems

Floating- vs. Fixed-Point Mathematics

Another topic of some dispute is the computational approach used in various DAWs to crunch numbers for signal processing. It turns out that software developers might implement different methods, depending upon factors such as hardware support, ease of coding, and portability. Some DAWs utilize floating-point math, in which data is represented in a manner resembling scientific notation. Others do fixed-point math, using a prescribed number of integral and fractional digits. There are those who feel that floating-pointmath is superior since it is more flexible and can convey a wider range of values than fixed-pointcomputation given the same number of digits. However, the resolution of floating-point representation decrease as the values increase, and the noise floor also varies. Ultimately, proper coding should make these issues insignificant. If you don’t believe me, maybe you’ll listen to Colin McDowell, founder and president of McDSP, one of the leading developers of third-party plug-ins for Pro Tools and other DAWs:

“If the fixed vs. floating point question is in regards to algorithm quality, the difference should be negligible. The code can be created on either platform to equivalent specifications. As long as the input and output bit depth are equal to (or greater than) the bit depth of the files being processed, and the arithmetic processing is double that bit depth (i.e. double precision), output signal noise level can be made to be lower than the smallest value representable in the output format.”

In the past, Pro Tools HD required TDM hardware whose DSP chips utilized 24-bit inputs and outputs, while RTAS signal processing supported by host-based systems was based on 32-bit floating point arithmetic. Both were capable of producing high-quality results, but some users felt that subtle differences could be identified between the two methods. What could have explained these perceptions? Was this another example of mind over matter, or were there differences in coding methods that could yield audible disparities?

Fortunately, as of Pro Tools 10 the above issue is of academic interest only since all computation is now performed via 32-bit floating-point math. By design, the DSP chips used in HDX hardware do floating-point arithmetic just like the signal processing in host-based sytsems, so (essentially) the same algorithms can be used for both native as well as DSP processing. It’s nice to know that any given plug-in should sound the same regardless of the platform, and the use of 32-bit floating-point math also provides a mamouth amount of headroom that makes it virtually impossible for users to overload computation engines.
