Summary0006127: midi state tracker issue (extra note on/off)
DescriptionDepending on playback start time, there are duplicate note-on messages.
Ardour 3.5-4264-g4d370b8
Additional InformationAttached session takes care of setup steps (except backend selection).

1) Create a new session (use 44.1KSPS)
2) use Dummy Backend, (Silence, 44.1K, 1024 fpp, Audio to Midi)
3) create an Audio-Track and a Midi-Track without synth
4a) connect MIDI track out to system:midi_playback_1
4b) connect Audio track in to system:capture_1
5) move playhead to 00:00:02:00, step-entry a few midi notes (all 1 beat long)
6) add a CC automation curve after the notes (snap all to beat)
7) rec-arm Audio-track


Now...
(A) move playhead to 00:00:01:00 (exact 44100), global-rec-en, record

(B) move playhead to 1 sample after 00:00:01:00 (exact 44101), global-rec-en, record

(A)
 All fine

(B)
There is an additional note-on at the beginning and a note-off end of the midi-region.
