As I did not see any activity on this report, I went out and tracked it down myself (by bisecting the homebrew repository). The problem appeared in version 4.260, 4.258 is fine.
@Andreas_Hegenberg, would you mind confirming and taking a look? This is quite disruptive.
I purchased Better Touch Tool specifically for this purpose, and no combination of settings or scripting I've tried (blocking or async) has managed to share MIDI values with an AppleScript. I even tried downgrading to 4.258 and it still doesn't work.
Ja 12, 2026 I am not able to get any scripts to run through midi triggers. Midi seems to be able to trigger other built in functions. The Run Script buttons works… but will not receive triggers from midi. Please help.
