You’re correct that it’s going to need to be done with patterns like I said about inputting scale and chord settings ahead of time. They’ll basically be blank patterns with his patch settings. He said he has the notes laid out on the mpc sequencer so it should do what he wants. I found another digitone thread where the gear is a little different but it’s the same:
I apologize to the op though if I wasn’t clear enough about what you’re actually doing to change the patch. You can do it, but you do have to set up your desired patch / scale / chord ahead of time and then use the pc message to switch patch as if it was a pattern. (or switch pattern as if it was a patch? sorry I know it’s more confusing to try and explain it this way. hopefully that still makes sense).
