Certain Sul tasto notes almost inaudible with Muse Strings

Issue type

Muse Sounds bug

Bug description

A number of notes fail to play back when using Sul Tasto technique on various Muse Strings instruments (esp. Violins II)

Steps to reproduce

1. Create a new score that has Violins II (Muse Sounds)
2. Add in a number of 1/8th notes, including the D, E & F at the top of the treble clef
3. Confirm playback works as expected
4. Add a "sul tasto" direction at the beginning of the measure
5. Play it back again and note that the Es & Fs are virtually inaudible (and sound slightly staccato?) and the D's are very slow to sound (and very quiet).
