I use an old tr-626 for live work, sequencing MIDI modules and other drum machines as well as feeding my eurorack the sync signal from the TRIG-out jack, I often leave the 626 in pattern step write mode and that lets me create on the fly. I lose the ability to have patterns all setup with the (useful) accent and flam already but those are easily added in on the fly. Can you do that in the BSP at least? or does that make changing patterns for the synth work impossible and now tied to the single pattern being open for writing in real time? could a module like LaunchCodes be more useful to you?
