Assign To Exclusive Group: 4

Assigns the selected pad/button to exclusive group 4.

Use Logic Pro Drum Machine Designer pad controls — Apple Support

Exclusive Group: Choose a group for the pad. You can assign multiple pads to the same group. As soon as one drum sound in the group is triggered, all other sounds in that same group are stopped. For example, you could group three pads with open, semi-closed, and closed hi-hat sounds. Only one of these sounds can be played at a time, mirroring the behavior of real hi-hats.

Create and customize Drum Machine Designer kits in Logic Pro — Apple Support

Create custom Drum Machine Designer kits with more than 2000 kit pieces patches from the Logic Pro sound library or use your own samples.

I keep thinking that the Drum Machine Designer could help with “drum replacement” or “drum enhancement”l. A lot of experimentation needs to happen.

  Select Members of Group 33

Selects all of the tracks (channels) in group 33. Useful for focusing on a smaller number of tracks. I can visualize a need for lots of groups when working on a soundtrack or a score.

Overview of groups in Logic Pro — Apple Support

Prior to mixing, you may find it useful to define some logical channel strip groups. You could, for example, group all drum channel strips under one drum group. This would allow you to control the group meters (volume, pan, mute, solo, sends, and so on) using a single control, while still maintaining the relative parameter values of each channel strip.

  Minimize Window    ⌘M

Minimize (Hide) the current window. Not documented as part of Logic. The Minimize command is a very common command found in almost all “native” applications.

NB windows in Logic play by very different rules than most typical applications. One example is the ability to have multiple windows of the same “name” — ‘Open Main Window’ creates a new main window each time you use the command. You can have many of them. See the other windows for examples.

Minimize a window: Click the yellow minimize button in the top-left corner of the window, or press Command-M.

You can set an option in Dock & Menu Bar preferences to have a window minimize when you double-click its title bar.

  Move All Region Data to Track Automation   ⌃⇧⌘↑

It is not clear to me why the assignable command is ‘Move All Region Data…’ as opposed to the documented ‘Convert All Region Automation…’. My guess is the ambiguity of convert vs. move. Basically the region automation goes away when it becomes track automation.

Some day I will start automating things.

Convert All Region Automation to Track Automation: Converts all region-based automation to track-based automation, regardless if it is currently visible onscreen.
