In reply to lost1977:
I know GarageBand a little, but use Logic myself. I'm not sure what other mobile apps do a similar thing.
For Windows there is: Cubase, Pro Tools, Reaper, Ableton Live Fruity Loops, Sonar and Reason. These are all audio/MIDI sequencers (or DAWs as they are now called). There's probably others too, but they all do basically the same thing.
