A MIDI transform function would be a powerful feature if it could be implemented.
I’ve got a setup with the MC8, Yamaha DTX M12 (drum pads), Helix Stomp (guitar modeller) and Boss RC-500 (looper). The RC-500 needs to see two CC messages to engage a function (one CC at 128, one CC at 0). The DTX M12 can send MIDI messages, but only single messages with each pad strike. Would be great if I could turn on/off the looper from the drum pads, with the MC8 in between transforming a single MIDI CC command to the two CC messages needed to turn on/off the looper.
There are plenty of other more complicated examples I can think of. With the MC8 at the heart of your setup, you could possibly have multiple messages sent out to multiple devices resulting from one message received. Not sure if this is within the realms of possibility, but it would be a fantastic feature.
