Hi I’m looking at doing some music on my G4 450. I also want to do it by mouse, as I am a disabled person with limited use of my hands. The system should cost less then 1,000 dollars. Any suggestions on products?

What I think I need.
· A recording/mixing program. No more then 24 channels will be needed. Also voice recording capabilities.
· A synth program that has easy step writing on screen interface. Able to loop sequences.
· A drum program with the same requirements as synth.
· Effects program
· A exporter to formats like mp3 and QuickTime.

Anything else?
