This seems to be more addressing other DAW users like Studio One:

Indeed, @David Nahmani's book is a real time saver! Warmly recommended!

Did you have the chance to read this documentation?

Wild guess: what happens if you switch from Adapt to Keep before nudging your MIDI notes?

(I’m not familiar with your setup) Did you check in Logic’s Output settings and the Output devices selected in Audio Devices settings?

(Not at the studio to verify same) is there volume automation on those tracks or are you dealing with automation, while the Region automation takes priority over track automation project’s setting might be at stake?

I didn’t try it but I wonder if a possible workaround would be to import the project into a fresh new one but without selecting the ScoreSets among the data to be imported…

Try the folIowing : after one of the note is selected : using the arrow keys set the cycle (locators) around it : (default US KC= ⌘U) then issue the Select All Inside Locators command (default US KC=⇧L)

I wonder if rebuilding (at least partially) the project by importing data into a fresh new project (not using an existing template) could alleviate your issue?

Out of curiosity, do those regions contain program changes events?

Pond5 perhaps…

Have you tried renaming those (EXS24) presets for the specific purpose of your project, then include those presets in your project file?

First idea that comes to mind is AI… then mangle with different art softwares (photoshop, or alternatives)

That information also appears in the LCD (Midi In/Out option)… Have you considered/tried using the musical typing (keyboard) or the keyboard object in the Environment?

If that is a matter of screen asset management, working with screensets (which could be keyboard-shortcut driven) and/or I wonder (?) if the usual macOS window switching could help: Switch to the previous app: Press Command-Tab. Scroll through all open apps: Press and hold the Command key, press the Tab key, then press the Left or Right arrow key until you get to the app you want. Release the Command key. If you change your mind while scrolling through the apps and don’t want to switch apps, press Esc (Escape) or the Period key, then release the Command key. (sorry, not at the studio to verify same…)
