Description
Issue type
General playback bug
Description with steps to reproduce
I am not sure how to reproduce this, I have tried to create e new score with just the bass track, but that didn't work, so, instead, I have isolated the problem on a project I was working on. The problem appears in every long note in the whole project, so I have included the whole project as well, as well as a video recording of how it plays back on my end. The issue crops up in both musesounds and MS basic, and it doesn't have to do with MIDI velocity (all notes register as 64), and if I delete the long note, and replace it by a short note, the problem disappears, but if I press any number on my numpad larger than a measure on a otherwise fine note, the problem comes back.
