I think the pitfall for new OT owners is trying to do everyting at once. Just use it where you want to use it for, 1 step at a time.

You want to sequence other gear? Just pick a midi channel and start inputting notes in the sequencer.
You want to use it as a drum computer? Just load up some samples in the audio tracks, and start inputting steps.

Don’t try to mix up the different jobs it can do at first.
