text is a tough way to do audio — ⇧ SHIFT — ⌃ CONTROL — ⌥ OPTION — ⌘ COMMAND
Quantize 1/16 Triplet (1/24)
Set the note quantization to sixteenth note triplets — one twenty-fourth of a bar.
Logic Pro Quantize parameter values — Apple Support
You can quantize selected audio or MIDI regions (including a mixed region selection) using the Quantize parameter in the Region inspector. This parameter determines the division of the quantization grid.
Insert Silence Between Locators (Global) ⌃⌘Z
Inserts “empty space” between the locators. Allows you to easily create gaps in a project so you can add new regions (MIDI or audio).
Add or remove gaps in a Logic Pro arrangement — Apple Support
Alternatively, you may want to insert some empty bars in the middle of a project, to create space for another chorus, verse, or bridge, for example. As with the previous example, all existing tempo changes and so on are moved accordingly (to the right by the number of inserted bars).
Set Global Edit Mode to Note ⌃⌥N
Changes the global edit mode to Note. This can be achieved by selecting ‘Note’ from the menu at the top of the Step Sequencer window.
There is an annoying behavior when using the keyboard commands to set the Global Edit mode. If you select the mode that is currently selected you get a flash of the screen and a notification that you can’t set the mode, or it is already selected. That’s essentially a broken message. You can’t do this, or you already did, so I am warning you…hmmm
Use Step Sequencer edit modes in Logic Pro — Apple Support
Note: Drag vertically in the step to set the Note value from –12 to 12 semitones, transposing the pitch of the step in notes.
Logic Pro Step Sequencer overview — Apple Support
Using edit modes, you can control different attributes of the note or event triggered by a step. Some edit modes apply to only one row type, while others are common to both types. For note rows, you can change the velocity, pitch, gate time, number of note repetitions in a step, and other attributes. For automation rows, you can change the value of the automated parameter. Edit modes common to both row types include skipping and tying steps, changing the loop start and end point, and changing the step rate.
Region Automation: Aftertouch
Set the Region Automation parameter to Aftertouch.
The Automation/MIDI area in the Piano Roll Editor in Logic Pro — Apple Support
Choose the desired automation or MIDI controller parameter from the Automation/MIDI pop-up menu.
Select And Operate using Transform User Preset 20
Process the MIDI events using program 20. Lots of program slots. Unlikely to ever need 30 user-defined programs. The built-in programs do a lot of the typical heavy lifting.
Logic Pro MIDI Transform window overview — Apple Support
The MIDI Transform window is a powerful tool for edits that would otherwise be impossible (or tedious). For example, imagine an orchestral project that has been sent to you for editing. The individual violin and viola parts were recorded with a different string library. Two hundred MIDI regions contain aftertouch information that introduces an unpleasant pitch modulation, and some sample layer switching artifacts when played with your string samples. After looking at this aftertouch information, you discover that only a small range of values is causing the problem. Your options: edit your sampler instruments, manually remove all aftertouch information (region by region, or globally, thus losing the performance benefits that the aftertouch information provides), or alter the problematic values in the MIDI Transform window.
