I can’t help but wonder why you would want to do a thing like that?
I want to use Sync24 (or equivalent) as Mastersync.
I want try to do a MIOS slave sequencer. It’s for live act.
Admit that i just want a fat rythm over my gameboy, i think it’s more logical and more interesting to give the greyboy the MASTER control over the midi beatbox. (the gb sequence the tempo !!)
