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.
Problems with Amplitube & VocaLive in Audiobus
I have the IRig HD, IRig Mic, VocaLive, Amplitube and just purchased the Audiobus app so they would work together with my IPad. The problem is that I cannot get sound from the IRig Mic/VocaLive and my guitar through Amplitube to work at the same time. I have tried every configuration with VocaLive and Amplitube that I can think of in Audiobus. When I connect the IRig Mic or my guitar to the IRig HD, the last one that I connect to the IPad is the one that works, and works in either app. I have had several discussions with Audiobus support staff and they seen to be at a loss. Can someone help me on this?
