I have a OP-1 brand new, just 1 year using here in São Paulo, Brazil.
So far so good. Awesome instrument!
I have a setup with Ableton Live, Korg Volcas, Controllers anda the Op-1.
Everything controlled by mid in/out. Ableton is the Mid Out and everything else as Midi In.
This week i've got this problem on OP-1 and it's stopped starting :(
Unfortunatelly i have to use WINDOWS 10, Apple here in Brazil is to expensive :(
Can you help me? I love it so much! It's so much fun!
