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.
"Not so new track"
I recorded this in my mini-van (yes, it hurts to say that) while waiting for my daughter and her friends. I drove them to an amusement park a little over a year ago and brought my iPad, my Les Paul, my Fender P bass, a condenser mic and stand, Focusrite 2i2, Apogee Jam, cables, and an extension chord. I started just noodling around with a drum beat in AmpliTube. I copied the drum pattern and rhythm tracks to MultiTrack and AudioBused (yes, I "verbed" AudioBus) the bass, and vocals via AmpliTube. The lead guitar parts were AudioBused via ToneStack. The song sat for a few months as I thought I would do more with it. I posted it to my SoundCloud awhile back, but it occurred to me what a great time I had finding a few quiet parking lots, one next to a lake, while waiting for my daughter and her friends. It was just all so easy to do.
