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.
Variable midi clock / tempo change for live use
What apps can play back a prerecorded variable midi clock that i can then sync everything to, and is practical for live use?
i.e. i have songs that i need to add some looseness too... as well as some songs that have some gypsy style tempo increases.
...preferably with a song list, or controlled by program midi changes so can be used in a live set, when songs change?
