Summary0007818: Doubling notes in MIDI tracks if speed changed
DescriptionVia youtube discussion ( https://www.youtube.com/watch?v=J6bU4GdUVYc ) I got informed, that the step sequencer plugin B.SEQuencer start playing notes twice when speed has changed in Ardour during playback. I could reproduce it. Initially, I thought it is a bug in my plugin. But the dump of the plugin MIDI input (coming from Ardour) clearly shows two (or even more) NOTE_ON signals which are not interrupted by NOTE_OFF. This typically occurs if the speed is changed at the end of a note / begin of the next note.
Steps To ReproduceMIDI track, add some notes, one after the other, not overlapping. Start playback and play around with shuttle speed control. Monitor the MIDI signals.
