Update: I think I’m going to follow the advice of many of you - locking samples to steps in patterns. I’m finding that moving from part-to-part isn’t working well because patterns and parts are not differentiated from one another. So I think the move is to load tons of samples and loops into the project, and then lock the samples I want to the particular steps of each pattern. Might be a little bit more work but seems to be more conducive to playing live, at least in the workflow I prefer (using the Octa as more of a looper than a drum machine).
