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.
Korg microKey Air 25 - Good Condition; $55 + Whatever shipping we work out.
I've found my microKey Air just a touch too big to fit in my overall iOS ecosystem, and as such, would like to sell to a good home. We can work out shipping.
It is in very good condition, with the exception that the note names are written on the keys in gold sharpie (don't judge me! I'm sure some isopropyl alcohol will take it right off? I'll even try for you)
If you're interested, drop me a line.
