Thank you for the welcome & info @sezare56

I have the ST, DT, DN & A4. The OT does seem to behave quite differently, although far from alien & close enough to the others to be able to jump straight in (to a point).

To be honest I haven’t saved any parts yet (only via the project)… but I’ve just twigged (off of the back of your comment) that parts are per pattern, aren’t they? Not a new set of 1-64 patterns per part. It makes sense now. I need rewire how I think of this workflow.

So, I could set part 1 on pattern 1 only & then part 2 from pattern 2 onwards? Or have I got that wrong?? Once saved, do parts then change automatically to their allocation as you move through the patterns? I guess the best way to find out is to get back on the horse!
