Or the other way round? Does the OP-1 sync to the R16 via Midi? It would be a cool expansion to the 4 OP-1 tracks. The R16 Recorder is able to sync with another R16 via USB to double the tracks. But than it should also work with the OP-1, right? Has anyone tried it?
Hi dinraum,
I don’t think it’s possible: in this Sound on Sound review, they specify that “With no MIDI, word clock or other sync options, you’re dependent on the
accuracy of the built‑in metronome if you want to line up R16‑recorded
material with anything else”.

We got to work this musician’s skill now 
Uh no Midi sync? Strange. I expected it because it can be paired with another r16.
So my aber the old way with a click track. Routed to the op-1 for external sync? Or does the op-1 only sync via midi? That way it could possibly be done with the Bastl klic Box.
@dinraum the OP1 only syncs via MIDI unfortunately. I have a Bastl Klik and doesn’t do anything going IN to the OP1 (great for taking the click out and boosting it tho)
