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.
Tomorrow is Yesterday (Kronecker, AddStation and Sector -- Ambient Drone)
Quite a bit of samples I worked with through Koala in this. I recorded the ambience of my apartment when just doing stuff and the window was open so birds and cars got mixed down to rhythms and screams. Lots of fun. I also used @iOSTRAKON stEAL my chant (Thanks!). Only synths used are mentioned in the title.
