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.

Good luck! Gadget is NOT a DAW so you're way better of creating the backing track in Gadget and exporting it as stems and using a real DAW to do the rest...
+1.
Move your Gadet stems to Cubasis.
Or a cheaper option, "Multitrack Recorder" by 4Pockets.
Or the free option, Garageband.
Nice one, cheers.
Cheers!
Or audio evolution mobile if - it has some unique editing options.
