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.
I’m looking for an app that does scales mode
Is something like this exist? On the Launchkey MK3 you can set a scale (let’s say C Major) and if you play a G#, will you hear an A because G# is not in the C Major Scale. I cannot believe I can’t acheive the same result with an iOS app (Drambo maybe? But I’m not creative enough to find how).
If you have suggestions, I’m here to listening.
