Sustain pedal / held notes randomly cutting off in Logic

Hi everyone,


I’m having a strange issue with Logic Pro on my Mac mini M4 (latest version). I use a MIDI keyboard connected over USB and I only play Logic’s software instruments.


After a few minutes of playing, the notes I hold down (holding notes or using the sustain pedal) suddenly cut off after about a second. There’s also a small clicking noise when the note cuts.


The odd part is that the problem goes away as soon as I switch to another track or create a new one. But if I try to delete the buggy track directly, Logic freezes or crashes. So far I’ve only noticed this with the piano instruments, not with synths or other presets.


I use a USB hub with my keyboard, but since the issue disappears immediately when changing tracks, I’m pretty sure that’s not the cause.


Do someone knows how to resolv it ? Thank you !

Mac mini, macOS 15.1
