I was intriqued so I downloaded the G2M app tonight and it worked okay controlling midi instruments in Cubasis. I Find that the G2M app is a little buggy. Sometimes I have force quit and restart or turn the audio button off and on once or twice but then it works fine. Actually had a lot of fun playing with the app.
Just a compatbility note. Got G2M to work with:
Cubasis
Garageband
bs-16i
Alchemy
Music Studio
Couldn’t get it to work with Sunrizer even tho it showed G2M as the midi input.
Couldn’t get it to work with SampleTank, not surprised
