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.

USB powered hardware. Does this include using a USB charger straight from the mains.
I have always assumed that powered via USB means that you can power whatever it is from the battery of a nearby computer. But can you also plug it into the wall using the same adaptor that we all know and love for charging devices without causing a short circuit and the frazzelment of said instrument? I’m assuming it does but I’m to frightened to try.
