Hi Jerry,

I just downloaded the R16 manual and was surprised to find that there is not a MIDI on this unit. Unfortunately I don't see any way of syncing and external device (other than another R16 via USB) to the R16. You're just going to have to do you mixing in the arranger and then record everything down to two tracks for stereo. Then of course you can overdub many more tracks in real time into the R16.

Somewhere I recently saw a little box that can convert USB-type-MIDI to the standard 5 pin DIN plug MIDI but that box isn't going to solve this dilemma.

Best Regards,

Dave
