A while back I upgraded to a Mac Studio and this week I was messing around with Massive X (it was pretty painful to run on my old iMac) in Ableton. One thing that’s been extremely annoying is that notes hang forever if you stop playback in the middle of a note.

A little googling seems to reveal that this is a bug on Apple Silicon. Until then you can just drop the aptly-named ShutTheFuckUp MaxForLive MIDI device on your track. Thanks, squeeb!
