The question was: “did you save the parts” . Your answer should simply be “no I didn’t”. That is something I learnt about the Octatrack. It’s a very rational machine. I too made assumptions when being puzzled by a WTF moment because I had a preconceived idea of what the problem must be, and instead of following advice I didn’t understand, I gave answers that tended to confirm my own thoughts.
It’s like going to the doctor. Answer the questions, don’t elaborate: you are the patient, not the doctor!
Many topics on the subject of parts saving, for instance Saving the project save the parts? ( that doesn’t mean the root cause of your particular issue is parts saving, but it’s relevant to the actual discussion)
Also, prior to saving, always check one last time that your project plays OK, then do not touch anything and save parts and project. The encoders get whacked out of position really easily and depending on what page you’re on this can have serious consequences (but almost always reversible at the expense of a bad WTF moment). Having the OT hooked up to a midi set-up is a dangerous thing to to do as well. If you don’t need midi control, switch off “audio notes in” and “audio cc’s in”
