MDL Playback Issues
I began to write a new drum cadence and everything was working fine. Randomly, when played back, the snare, tenor, and bass drum parts would start not playing some notes. They were being highlighted by the scrolling bar as playback was initiated, but no or very little sound was being produced. I reset all note velocities to original values and tried again to no avail.
I like to manually offset the velocities of accented notes to get more contrast, and I don't know if this confused the system into making some notes have 0 velocity or something like that. I tried restarting Musescore and restarting audio drivers without luck.
This glitch results in a choppy sound that is not able to be worked around.
