Twister Posted August 17, 2021 Share Posted August 17, 2021 Logic sends note off command for MIDI notes close to the end of a cycle ahead of time. This causes the note to be shorter than inteded, or if note off comes before note on, the note will sustain forever. Steps to reproduce: Create an External MIDI instrumentTurn Cycle Mode onCreate a note close at the end of the cycle loop. According to my calculations, notes starting 155 ms or less before the end of the cycle should reproduce the issue, but settings may affect the results. This means that a 1/16th note at the last 1/16th of the cycle will cut immediately when played at 96 bpm, but at 97 bpm and up it will sustain. Play and listen to the instrument or monitor the MIDI signal with software. Note off should trigger earlier than what's written in the sequencer.

David Nahmani Posted August 18, 2021 Share Posted August 18, 2021 Is this only with external MIDI instruments or can you reproduce with internal instruments? Can you share a project that exhibits the issue? How to attach files to your post Quote Link to comment Share on other sites More sharing options...
Twister Posted August 18, 2021 Author Share Posted August 18, 2021 Is this only with external MIDI instruments or can you reproduce with internal instruments? Can you share a project that exhibits the issue? How to attach files to your post So far I've noticed this behavior only with external MIDI tracks without External Instrument plug-in. Check out the attached project. When I press play, MIDI Monitor logs events: 03:33:07.248 To Port 1 Note Off 1 F3 64 03:33:07.283 To Port 1 Note On 1 F3 80 note-off-bug.zip Quote Link to comment Share on other sites More sharing options...
