MuseSounds playback does not respond to note velocities in "Playback" panel

Issue type

General playback bug

Description with steps to reproduce

When you adjust the note velocity of a percussion instrument the playback volume remains unchanged.

1. Set up a basic percussion of, say, "four to the floor" bass drum beats, and put it on repeat
2. Play the pattern back and make sure it plays at the assigned default note velocities (64)
3. Now change the note velocities of the notes.to 127
4. Play back the result.

Expected result: The playback should reflect the new note velocities.
Actual result: The playback velocities remain the same (at 64)

In fact you can change the note velocity to any value, but the playback velocity remains stuck at 64.
