I think both of those options would work. I have one suggestion too. I had an OP-1 for a long time, and mine used to get pretty noisy when running on midi sync over USB whether it was running from my laptop, iConnect or the Oplab. I bought a cheap USB noise filter which really helped to clean up the sound.
I don't know if you have experienced / will experience this but a $5 noise filter can really help with MIDI sync on the OP-1
