I’m not sure if this is a bug or if it’s working as intended. If it’s the latter, I suggest this becomes a feature.
The re-record feature only works in the project overview window, not in the score or key editor. Pressing record while recording is in progress causes the locator to reset to the original position and begin recording again, but the recorded notes and controller data aren’t removed. I have tried all MIDI record modes with no avail.
