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.
Feature Request - Keyboard Shortcuts for Music Apps
In GarageBand there are a good selection of keyboard shortcuts. Do any other music-related apps provide keyboard shortcuts? I don’t use GarageBand - but having editing options on the Keyboard could be very useful in a DAW.
Also, GarageBand has the document preview option - long tap on the app icon to show a list of your recent Songs. Do any other music-related apps have document previews? I’m thinking previews could be a good option for AudioBus - Long Tap the App icon and a list of your Presets / Last Session / New Session options pop up.
