Select And Operate using Transform User Preset 11

It’s good that there are up to 30 preset transforms. Unfortunately there is no way to see what, exactly, Transform User Preset 11 *is*.

It’s like trying to program with numbered subroutines or functions.

Far safer and more meaningful to “Open MIDI Transform ⌘9′ and select the transformation there. I guess some people can keep it straight between Group 27 and Transform Preset 27 — not me.

Oh, yeah, this is exactly the tool I was looking for back in the 1990s when I was programming MIDI “orchestras”.

Use MIDI transform sets in Logic Pro — Apple Support

Depending on your needs, it may be worthwhile to create your own transform sets. These can be configured and saved as part of a project. (Doing this in your template projects makes your transform sets available in all projects.) Your transform sets are shown at the bottom of the Presets pop-up menu.

  Fix Displayed Note Positions

We need to understand “display quantization”. It means what I think it means, but I had to go hunting in the documentation to confirm. Moves displayed notes to their “proper” positions. “Set the visual quantization value” describes what is going on, and why we might need it.

Quantize the timing of notes in the Logic Pro Score Editor — Apple Support

You can quantize, or automatically correct, the timing of individual MIDI notes in the Score Editor. This is useful when regions in the track contain the right notes, but are not perfectly in time with the project. When you quantize the timing, items are adjusted to the selected note value. You can quantize the timing of regions with drums, single-note instruments, and chordal or polyphonic instruments.

Logic Pro Quantize region parameter — Apple Support

You can fix the display quantization of all MIDI events in the projects using the Score Editor’s Functions > Quantization > Fix displayed Note Positions and Fix displayed Note Positions and Durations commands. These commands may be useful for exporting projects (complete with display Quantize settings) to other notation programs that don’t feature display quantization. The commands are also available from the shortcut menu when you Control-click notes in the score.

  Toggle Hide Group 55

There are currently only 32 groups available. Maybe in the future?

Group editing in Logic Pro — Apple Support

Group editing allows you to perform many editing, arrangement and timing operations on all group member tracks simultaneously. For example, you can combine the comping feature with group editing so that every comp uses the same takes. You can move, resize, and arrange regions for all group member tracks together. You can also adjust the timing of the group, ensuring the group remains in time.

Should learn something about Groups each time I enter one of the bogon commands…

  Select Same Channels    ⇧H

Selects all events that have the same MIDI channel.
