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.
Devs, just a humble request to help us help you. Musicians wear t-shirts. iOS musicians are proud to support the apps that inspire them. It's ridiculously easy to set up a t-shirt shop from any number of online services (e.g. spreadshirt). I would rather buy a Sunrizer t-shirt than Roland. How about a Loopy shirt, Michael?! Oh, and one last request, please make the American Apparel shirt an option. Thx!
