Description

Describe the bug
The trill sounds inconsistent, the timing is off and the dynamics are uneven when used with Muse Sounds; works as expected when used with MS Basic Sound Font and in the MIDI output.

To Reproduce

  1. Use any Muse Keys sound
  2. Play a bar which contains a trill

Expected behavior
A clear and crisp trill plays.
