NO, I don't have a solution. I just wondered if anyone had any ideas of a way to make Garage band play through Airtunes and AEX.
Of course, one can finish a project and then export to iTunes (mp3) and then play it, but...I have a large and powerful stereo system which is fed by the Airport Express (so I can play Airtunes through it), but it is just inconvenient to set up all my musical instruments, keyboards, Garage band things next to that amp. Also, it is nice to play some itunes things and then switch back to Garage band. Or just to hear the "nearing completion" projects in real time.
Is this possible at all? Theoretically? To make Garage band feed something that pretends to be an audio file for itunes to play?
Any ideas?
