I am a newbie with my E3. I figured out how to connect to garage band whereby I can play my piano and have the notes saved. I also downloaded a separate program called MidiMock (on my Mac) where I can use my mouse to click a key....and it then plays the Piano key.
What I am not able to figure out is how to play any Midi file or any garage band file that I just recorded so that it plays back on my Piano. What am I missing?
