sorry for the spam chaps,
I have it now pretty much the way I’d like it to have - however the OT tempo detection seems the biggest hurdle:

I’m using a metronome (old fashioned) set to 76 bpm.
now I record 3 chord stabs with a long reverb tail. 2 bars each
after the end of the sixth bar I press the 2nd record button and playback starts
it’s playing along the metronome nicely and accurate enough for my needs
now I tempo sync to the pickup machine (track+tempo) and the OT (pretty consistently) tempo is set to 102 bpm (+/- 1 beat) depending how accurate I play
for what I’m trying to do, I need to use the pick up sync as I’d like my MD to start after a few runs. funny enough it kicks in exactly when I want it but since it’s set to the wrong tempo it doesn’t make any sense musically. and also if I force the OT to the desired 76bpm it starts to retime my loop completely needlessly (and introduce artefacts)… and of course the sequencer doesnt start in sync unless i start it in sync manually - which I don’t want to rely on)

any ideas? please help. cheers!

EDIT: after practicing to play it tightly alongside the metronome I can get the OT to consistently mis-guess the tempo at exactly 101.5bpm. very annoying. hope anyone can chime in
