Audiobus: Your virtual music studio.
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.
Relative volume between YouTube other apps and Audiobus 3
Is there any way that you can give us control of the relative volume between Audiobus and other apps such as YouTube or Google Play and in this way allow us to lower the volume of these other apps relative to AB3? Sometimes I want to play along with those apps but I find they are often quite loud compared to my apps in Audiobus 3. Thanks
