Thanks jeffe -

Yeah, that’s how I used to work, syncing the machines manually in time with Logic, then recording the audio chunks and then aligning and chopping, etc.
Since getting the AR & A4 I’ve started writing the drum patterns/sequences while sync’ed to Logic - which for me is hugely inspiring and is a faster way to work. It made me want to do the same with the MD & MM.

I tried what I proposed yesterday (Midi thru the AR & A4 to MD & MM) and it worked very well, but I will try what you suggest tonight, using 1 thru output to MD then MM, thanks for the ideas!

And yes, I am looking at the Sync Gen (and the Roland SBX-1) but I do prefer solving problems before I spend money - so many times I’ve spent the money first and still had the problem!
