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.
Album made with 7 samples and 3 apps
This isn't my music—I came across it today in the Holderness Twitter feed and really enjoyed it. From the description:
Memory Fades by DEFENESTRATE
An experimental departure from the dance floor of Cryptic Cut. Defenestrate is organic, eastern, ambient and glitchy, All takes were recorded in one or two live performances with the final rendering featuring live ad libs of reverb and delay decay or sample manipulation . 'Memory Fades' is constructed, warped and recycled from two very short recording sessions. 7 short samples with a mixtures of riffs, one hit chords and found sound all recorded in iOs using the crappy internal mic.
3 apps were used: Samplr, Crystalline and AudioBus and mastered with Positive Grid - Final Touch
