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.

Made originally for military and secret service use across the Iron Curtain, in the hands of a few avant garde musicians it became a magical lofi-tool and ghostly echo machine. Now this rare and rather finicky to operate piece of hardware is coming to iOS for the first time as a faithful yet modern plugin.
