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.
Question about audio interfaces
This is massively off topic but I’m running my monitor output on my interface to a tape recorder and I’m wanting to know if the signal is going through the AD conversion or does that only occur on the output on my iPad? Basically I’m wanting a completely analog signal to end up on the tape so I’m wondering if this setup is doing that or if it’s being converted to digital then back to analog in the process
