Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.
Download on the App StoreAudiobus is the app that makes the rest of your setup better.

Yes, I have that one also. Both useful tools.
Here's a new free software for sketching songs. Wish it was ios. Pc only though, but a great tool.
There's videos available when you dl the software. If you have a m audio keyboard it's a bonus. It offers hyper control. Amazing. I did beta testing with the software and m audio axiom air mini 32 keyboard. A lot of fun.
