Musescore General Full soundfont (sf2 version): fast violins/celli crescendo noticeably through long notes
When I enter a long note (i.e. > dotted quarter at around MM=60) in staves using fast violins or celli, the note exhibits a noticeable crescendo. It is so bad that sometimes a hairpin diminuendo applied to the note actually results in an audible crescendo during playback. For now, the only fix is to apply diminuendi to every single affected note, setting the velocity value to something in the 20 - 50 range, depending on the register of the note.
Since there are no circumstances under which the exhibited behaviour is desirable in live performance (i.e. it's not a matter of taste or judgment), and since it imposes a huge burden on the user, I'm hoping it will be treated as a significant bug.
Violas and double basses do not seem to be affected, or at least, not as much.
