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.
Cirrus - sax looping with GroupTheLoop
My new track CIRRUS - sax looping with GroupTheLoop iOS app (here on iPhone beta version, already available on iPad).
100 % made on iPhone 7 Plus, using various apps including GTL and Audiobus.
Instrumental loops are triggered live (including groups switching and drums muting), all saxes loops and sax solos are played live and recorded/performed in one pass in GroupTheLoop with a pedalboard.
No post production except for Lurssen Mastering Console on the GTL stereo file performance recording.
Initial loops are made in Audiobus with Ruismaker/Atom for drums, Volt/Lorentz/ModelD/Atom for pad, with various AU effects, and recorded directly in GroupTheLoop via Audiobus.
I just discovered GroupTheLoop recently while beta testing it on the iPhone, this app really rocks and opens looping to new possibilities!!!
