I just switched to an M1 MBP, and Jay-Bass, one of my favorites, is having issues:
First I noticed the A#-1 keyswitch for Mutes isn't working. All notes when holding that keyswitch are silent.
Then I holding the sustain pedal for Slides is also broken; slides upward seems to just be hammer-on, slides downward play some slide sample with a very long release (keeps sounding after notes and sustain pedal is released). For whatever reason a +2 or -2 semitone seems to work somewhat fine.
Tried this on Jay-Bass Bridge, Neck and Both.
