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.

Loopy/Audiobus squealing on iOS 8.1.3 iPad
Hi. I am very new to iOS music apps but have been trying out Loopy and Audiobus in hopes of building a nice setup for guitar and vocal looping. So I setup Amplitube on the input of AB, Loopy output and immediately heard nothing but a constant squealing noise. I also tried Loopy on the input side and speaker on the output and again heard nothing but squealing. My guess is that this is a simple problem to fix, some setting I'm missing, but after a day of searching I decided to reach out to the pros (or at least someone with more that 2 days experience). Thanks! Mike
