Summary0008215: MIDI notes sometimes not updating. Have to restart to get Ardour to register additions/movements.
DescriptionMIDI notes sometimes not updating. Have to restart to get Ardour to register additions/movements.
Steps To ReproduceImport some midi tracks into a session.
Move some notes around
Play again, movements won't have registered.
Additional InformationExamples here. Note that moving some "crash" notes to "ride" doesn't immediately update.
Then, notice that adding 4 count-off "stick" notes at the beginning doesn't register, but then the ride notes register.
Something is amiss with midi note updating.

I experience the same issue. After importing a midi file, changes within the midi region are not reflected in the playback.

Current workaroud: one can drag the imported midi from the region list onto a new track. But that gets cumbersome after a while.

Still having issues of this nature. Here's an example where I'm moving all notes in a midi track from channel 1 to channel 3 and they should sound like fingered bass. But they continue to sound like piano (channel 1).

I am unable to reproduce these behaviors.

Can you verify that this only happens with imported MIDI ? If you create the MIDI from scratch do the same issues still occur?

Yes, it only happens with imported MIDI. Recording/drawing in MIDI from scratch does not come with this issue.

Not sure if this is related, but there seem to be other "not updating" problems on midi tracks. I dragged an instance of fluidsynth from a drum track over to a bass track. I went into the new instance and changed the sf2 file to the "strings" sf2 file instead of my "drums" sf2 file (the setting had come over from the drag+drop).

But when I pressed play, my bass line was making drum sounds. I opened up the instance of fluidsynth for the bass track and verified that the notes on channel 3 should have sounded like "fingered" bass. Closed the window and tried again. Still drum sounds.

Closed ardour. Opened session again. Now it sounds like bass.

So yeah, just some weird "not registering the recent things changes I've made" type errors.

1) would say this reproducibility is always. With drag'n'drop midi, they seem too be 'immutable' for all cases

2) for me in mixbus 6.1 there seems to be at least 2 working ways to circumvent bug:
  a) with grab mode, select region, and in context menu midi -> unlink from other copies
  b) select with region tool, and consolidate

I've noticed that you can adjust a midi region to fix the problem without restarting Ardour. e.g. Drag a region edge a little. This will force an "update" or whatever is going on.

I just upgraded to 6.3.40 and this is still an issue

I also experience a lot of weird behaviour around MIDI tracks editing.
One that hasn't been mtentioned yet is that a note at the very beginning of a section doesn't show or play. It appears and starts playing as soon as I move the section start so that it doesn't coincide with the note startin position.

This has bene mentioned in literally dozens of bug reports, along with explanations for why it happens, and suggested workarounds.
