I should clarify what I’m trying to do – I’m hoping to get Music Mouse to spit out the harmonised notes that I’m sending to it from my DAW. I’d imagine that this is possible due to MM having MIDI in/out capability but it seems like this use case is not something MM is designed to do. Might have to put in a feature request.

FWIW, I can also get MIDI into my DAW when using the mouse to trigger the keyboard directly within MM so I might just have to use MM to generate harmonies then copy the notes into my DAW for the time being.

Thanks for the reply.
