[MU4 Issue] Muse Sounds Violin 1 - first note of certain phrases does not sound fully

Describe the bug
Using Muse Sounds, Violin 1 sound, certain phrases will play the first note so quietly that it's almost inaudible in ensemble context.

To Reproduce
Steps to reproduce the behavior:

1. Download & open https://musescore.com/user/2975/scores/8955661/s/f8Kbku?share=copy_link
2. Start playback in bar 8
3. Listen to violin 1 entrance in bar 10
4. Hear error: the first "E" barely sounds relative to the other notes (or maybe the others are too loud relative to the E?)

Expected behavior
The volume should be more even, as it is with MS Basic, or as it is slightly faster, or if I change sound to Violin 2

Screenshots
Here is that excerpt, plus a couple of reduced versions of just the violin 1:

Platform information

• OS: Linux

Additional context
It's not just the E4, as I can change it to some other pitches and hear similar. The effect goes away at faster tempos - a noticeable change happens at 120 BPM.
