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.
Ambient beat, DJ Shadow-esque: Severed Selfish - Kaki King flip
I sampled Kaki King for a track. I made it in GarageBand iOS, moved into Logic. Then I used a free web-based music visualizer to make a video.
Here is the visualizer. Probably does not work on iOS. This is the first time I have tried it.
It is customizable. There are templates. It is free.
