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.
Awesome Noise Gate auv3 - released by AnyoneAtAll?
I really like a good noise gate and one thing I really can't stand is a threshold without a super fine setting. On desktop I use Pro-G. I just can't see how a gate can command the price ProG does for iPad. As good as it is, it is still just a gate. Is there anything else in auv3 form that compares?
