Hey thanks, I got this working kinda. So far I've only been able to get the OPZ to control the microfreak over USB which is all i was actually interested in, so
So here's the settings for that if anyone else needs it -
OPZgo to the MIDI Setup page in the App (or go to the module track (track 14 i believe). Only check these options, everything else should be disabled I think (I'm not sure what half of these do even)
"Midi Out Enable" - Shift+3 on the OPZ
"Clock Out Enable" - Shift+5 on the OPZ
MicrofreakUtility/Sync/Source - can be USB or Auto
The Input channel you set on the Microfreak is important, and as far as I can tell, doesn't map up with the tracks on the OPZ. it's possible my MIDI json is messed up on the OPZ, I'll have to take a look, but i get something like the following -
The melody Track on the OPZ (Track #6) is Input Channel 1 on my microfreak
The hi-hat track on the OPZ (Track #3) is Input Channel 6 on my microfreak (i think)
The other input channels are similarly mixed up. I haven't had time to make a proper mapping of it yet. So yeah basically...once you get the MIDI settings right, set up a sequence on a track on the OPZ, and just keep changing the Input channel on the microfreak til you hear it coming through and you should be in business.
