Say my Octatrack is the master, Sync out only, and A4 + OP-1 are plugged in the same MIDI USB hub: as OP-1 is resending the clock, A4 gets a double click and it’s bpm is thus OT bpm x2. Pretty annoying.
I reported it to Teenage Engineering, but if anyone can confirm this with last OS (still haven’t checked yet) please report as well.
