I am looking for a list of what can be controlled by a midi controller in Garageband 10 and what midi messages need to be sent to control them. When setting up custom midi controls for other software and garageband happens to also be open I have discovered some accidentally. Example would be Data CC9 mutes the selected track. It just happened to be the same thing that scrubs a track in my Djay midi controller. Would be nice to have a list of what midi messages Garageband is using and what they control. I know there is little that can be controlled in Garageband, but it would be nice to use what is there and avoid crossing paths with them by accident.
