So a brief update to this...
I have now heard back from Arturia and they said they are aware of the issue and are working to fix it ASAP. From researching forums I can see that the issue has been present since at least summer of 2021 and there have been 2 firmware updates since then that did not fix this. Also, I reverted back between all 3 available firmware versions and the problem persisted on all 3. To put it bluntly, I am not confident this will be fixed any time soon. This is unfortunate because stuck notes are a complete deal breaker for me. I would expect even the cheapest synth to be able to play octaves while being used as a DAW controller, regardless of what the octave setting is, and feel that the PB should have never been released like this if proper quality testing would have been done. Don't get me wrong, the PB sounds amazing for sure and I love what Arturia does but for a flagship synth with a retail price of over $3000 I expect basic MIDI to function properly. Unfortunately I returned mine and went with a Prophet REV2. I'm shocked there aren't more people complaining about this but perhaps most folks use this as a standalone. Anyway, good luck everyone.
