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.
Best Apps for iPhone SE
I have a used iPhone SE that I use occasionally as an Audiobus Remote but it's largely unused since I use my iPad for music most of the time. But Jakob's video for Koala made me curious, what apps are perfect for small size screens?
I don't plan on buying a larger iPhone since I prefer Android for mobile, but for sub iPhone 6 sizes, what apps do you still like using?
