Sadly it looks like Midi support is not confirmed as of December 2023 for the OM-108. But given the decision to call it OM-108 and I think it was the OM-200M, OM-250M, and OM-300 that had Midi output, it worries me somewhat that it will not be present. As much fun as it looks plugging this into various effects, I can equally well imagine it being a blast to use it as a Midi controller with a very unique interface.
Trying to use midi out from it is very weird, it’s all pitch end and +1/-1 for strum direction..
