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.
Loopy Pro - Quiet Audio Session Recordings
So when I session record audio in Loopy Pro (Combined Input/Output) to share a song sketch with other musicians, the volume always ends up being low when you play the resulting file on a phone or in a car.
Is best practice to just crank up the master output to +12/+24db in loopy pro when session recording? I feel like maybe the audio quality isn't as good when I do that. Maybe some clipping.
