Description

Issue type

Muse Sounds bug

Bug description

When adding a tempo change on a score, I sometime notice that the next bar doesn't play the pedal effect when using a MuseSounds piano (tested with Soft and Grand).

Steps to reproduce
  • Create a score for piano solo and write some bar with one pedal marking per bar.
  • Add a tempo change on a bar (like rit. or accel.) and start playback.
  • The next measure plays as if there was no pedal marking.
