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 Store
Audiobus is the app that makes the rest of your setup better.

I've taken advantage of multiple tracks to use 3 drum kits from GB. One for kick & snare, one for hihats and cymbals, and one for percussion. All the instruments are GB, except that massive pad which obviously is Alchemy, and the lead which is a sampled note from NLOG, stacked over the same midi clip which plays a GB lead.
