When I hit a note or chord twice or more while my sustain pedal is pressed, then release the pedal, the note or chord sticks indefinitely. I have to press the midi panic button or click the chord(s) to stop the sustain. This happens only when any of the perform options are enabled, whether the notes/chords are triggered by keyboard or by clicking on them in the plugin.
If I only press them just once before releasing the sustain pedal they stop as expected. I’ve seen people mention sustain issues in Scaler 1, and you have mentioned the ‘Allow multi-trigger’ option, but I can’t seem to find this option in Scaler 2 to try as a troubleshooting step, if it’s even there.
