|Summary||0007726: MIDI track loses NoteOff for the first 1-2 notes|
|Description||MIDI track recorded with a bass line. Edited/corrected by hand. Sounds good. There is plenty of other stuff around it in other tracks, audio and MIDI.|
This particular MIDI track is verified with MIDI Tracer. NoteOn properly followed by NoteOff as expected. (There is no overlap.) Next step is to commit the track to audio.
Setup: MIDI track is soloed, output goes to external synth. Audio goes back to Ardour, to a new audio track. Arm recording. Start.
Expect: Bass line played back as recorded, recorded to audio track.
Actual: First 1-2 notes drop their NoteOff and linger for some time. Confirmed in MIDI Tracer, NoteOff lacking. List Editor shows very long duration. The problem persists even if I manually edit the duration of the first notes.
When listening without recording it mostly sounds ok, except sometimes it happens even then.
Workaround: Add a few notes several bars before the real track so they have time to die out. Kludgy but worked.
|Additional Information||It's an all-USB MIDI and audio setup. Audio goes to the USB connector of a Behringer mixer.|
||This happens on a regular basis. Playback from MIDI without problem. Recording (bouncing to audio): the first notes hangs (keeps sounding). New workaround: Start transport (typically space bar), hit Shift-R (record) while it is running.|
||I can confirm this behaviour running the distro supplied Ardour from Fedora 29.|
