Playback not respecting dynamics on certain channels in expressive strings?
In mm 1-6 of the attached example file, I have Vln II and Vla marked pianissimo (velocity = 33), but they seem to be playing back at vel = 80. To test, I repeat the section with the Vln II and Vla at fortissimo (vel = 112) in mm 7-12, but can't observe any difference in the playback volume. However, the pizzicato channel (in the Cel and Cb parts), which goes from mezzo piano in mm 1-6 to fortississimo in mm 7-12, definitely has a noticeable difference in volume.
Similarly, the tremolo channel in Vln I & II in mm 13+ doesn't seem to respect the dynamic marking when played at pp or fff.
This score was originally created in an earlier Musescore version, and I had made lots of adjustments to individual note velocities. I've followed the instructions at https://musescore.org/en/node/290616 and https://musescore.org/en/node/277424.
What have I missed?
