Your experience sounds like mine when trying to do this with the A4. Maybe we should log this as a bug and see if they respond with some info. I can’t imagine they deliberately hindered this but maybe it’s a side effect of the design.

My plan is to use the OXI One to drive the tracks, since it has far superior melodic sequencing and options for improv. But I want to use the onboard sequencers for p-locks like you’re attempting to do.
