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.
SO Strange... (musing)
What are “wrong” notes? I play in an arbitrary scale of frequency ratioed patterns and it sounds cohesive. I play a note sharp or flat not in the scale and it sounds “off”.
Wait a few moments and play the “wrong” note in another frequency ratioed pattern and it sounds like it belongs. Particularly vexing if the note which was previously wrong is the root or tonic/starting tone of the new pattern.
Like I said, musings.
