I am a new subscriber. Also trying to make that long journey from blues to jazz. My practice rig includes Mac and Amplitude. I was hoping to export the iRealbook midi file of a song to Garageband and the record accompanying rythmn and solo tracks (and even a vocal track). So far the only thing that seems to work is running a stereo mini Jack from the iPhone to the Mac and recording an Analog version of the song. This has problems in that I seem to pick up some hiss. Is there a way to export a MIDI version of a song to Garage Band? Great product. Best $15.00 I ever spent.
