I had a bit of a breakthrough moment with the m8 and the op-1f today. I’ve been trying to get midi over USB to work between the two devices last year, but without any success.
I just tried it again and got at least part of it working now (sequencing the op-1f with the m8).
Here’s how I’ve done it.
- Connect the op-1f to the m8 via USB.
- Turn on the op-1f.
- Set the op-1f to receive midi note data on channel 1.
- Go to the screen that shows all connected midi devices on the op-1f.
- Turn on the m8.
- It will show up as a connected device on the op-1f. Set the midi note data to out on this screen. The options to change these settings will disappear if you leave this screen, or at least this is the case for me.
- Create a new phrase on the m8 using a midi out instrument that’s set to send on midi channel 1.
I haven’t gotten it to work the other way around and I can’t figure out why. Would be nice to use the op-1f to input notes into the m8, but no dice. However, sequencing the op-1f via the m8 is a bit more useful to me anyway, so I’m glad I figured that out.
