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.
NDLR for sale in UK
Anyone after one of these? They're currently unavailable to purchase due to Conductive Labs being unable to source components. They are reportedly doing a hardware redesign so they can resume manufacturing.
Anyway, I have one that I haven't much used, as the Keystep Pro was more like what I was after. It's as new in original box. Serial no. 011-0281-1909, with firmware 1.1.063. I'd rather sell it here than on eBay.
UK buyer preferred, but I will consider international shipping (and you will be responsible for local taxes and import charges). I'm asking £300 for it, shipping at cost.
