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.
label wording for apps with many output channels - like QuantiLoop - that are labelled
Apps like QuantiLoop have many outputs - MAIN , MONITOR. RHYTHM, track 1,2 etc.
Unless i'm missing something - AB3 doesn't have a means from telling what an input is. If the name of any channel ( where supplied by the app developer etc ) can be shown in small font somewhere - this would help a lot.
I note that for some inputs from QL there is an icon - but the wording would help too.
