[MU4 Issue] Adding dynamic has strange effects on Muse Sounds playback

Describe the bug
At least in certain cases, a dynamic that occurs anywhere in the piece can affect playback earlier in the piece, adding chorus/reverb like sound effects

To Reproduce
Steps to reproduce the behavior:

1. Create a new score with solo violin, using Muse Sounds Solo Violin 2
2. Add a few notes
3. Play them back, sounds like a single solo violin in a relatively dry acoustic
4. Add an f dynamic at the end of the piece (after or at the last note)
5. Play back from the start
6. Note that the violin now sounds louder, chorused and as though playing in a more reverberant acoustic

Expected behavior
Adding dynamic should not affect play back of notes before it, and even for notes after shouldn't change anything other than amount of attack/volume level.
