Then you’d select the tracks you wanted to subgroup, as described above-typical applications might be several multi-miked drum tracks or a collection of related guitar tracks or background vocals.
You’d create a new stereo Aux track (labelled Aux Input in Pro Tools), and set its Input to an unused stereo bus (remember, a bus is a signal pathway in a mixer)-this will be the subgroup Aux channel.
There are several steps to setting up a subgroup. Traditional subgrouping runs several channels through an Aux (Auxiliary) channel strip, allowing the level of all tracks to be adjusted at the same time via the Aux channel fader. This kind of temporary track grouping can be very handy, but as I mentioned it doesn’t allow for the most common grouping application, level (fader) adjustments-for that, you’d have to turn to the three standard grouping features. You can also insert plug-ins, bypass plug-ins, add Sends, or change track height (in the Edit window) to multiple selected channels all at once. These include basic channel strip functions like Mute and Solo, but not fader or pan moves. Once several tracks are selected, holding down the Shift+Option keys will perform certain operations on all the selected tracks at once. Command-clicking track names allows for dis-contiguous (non-adjacent) selection of multiple channels. In the Mix window, a number of tracks would be selected by selecting the channel names-clicking a track name to select it and then shift-clicking another name will select both channel strips and al the channels inbetween. Temporary Groupingīesides traditional subgroups and Mix Groups, Pro Tools offers a way to perform the same operation on multiple channels, which can be applied in many ways. Grouping tracks can also make it easier to perform an edit-like cutting or moving a section of music-on a number of tracks as a unit, though, as I said, I’ll focus more on mixing applications. Grouping tracks also allows overall processing to be applied to all the tracks in a group, like compressing multi-miked drums or adding an effect to a large number of background vocals. If these tracks have different levels dialed up, grouping allows them to be adjusted all together, changing the overall level while preserving the inter-channel balances of the different fader levels-with larger mixes, it’s much easier to adjust related tracks all at once than to have to make lots of individual track tweaks. Maybe the most common application would be to adjust the level of a number of (usually-related) tracks at the same time. There are a lot of reasons for grouping tracks together in a mix. VCA Faders work in conjunction with Mix Groups, offering additional convenience. The audio routing approach involves the use of subgroup Aux channels, re-routing the outputs of the tracks to be subgrouped, while Mix (and Edit) Groups link channels together without any signal re-routing. Tracks (channel strips) in Pro Tools can be grouped by either audio routing or by linking. Tracks can be grouped in Pro Tools for both mixing and editing purposes-I’ll focus mainly on mix groups. Pro Tools is a perfect example-there are three track-grouping features available, and each has its specific advantages. This has been done since the days of analog consoles, and today’s DAWs usually offer several ways to accomplish it. One of the basic requirements for mixing and editing is the ability to group tracks together and make adjustments to several grouped tracks all at once.
