Ok, I've got a nice MIDI keyboard device here, and I got a copy of ABSynth (really awesome software that sounds just like hollywood). Anyways, the only thing missing is recording! ABSynth can record, but only 3 minutes! I'm looking for something similare to OS X's Garageband for recording layers of MIDI music. I love composing songs freehanded, and garageband really makes it easy. Any ideas?
