Bug description

On the Pianoteq VST (and maybe other VSTs) the pedal sometimes doesn’t release.

Steps to reproduce

1. Download and install the free demo of Pianoteq 8 from https://www.modartt.com/try
2. Make a new piano score and choose Pianoteq 8 as the instrument.
3. Enter notes across two measures and add a pedal marking to each measure.
4. Change note lengths (or just save, close, and reopen score).
5. Hit play. The pedal doesn’t release between measures one and two.
