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.
Portal (Bome Network, Solo, Omnisphere)
This is a music track that I improvised on two MIDI keyboards connected to an iPad.
I used Bome Network software to send the iPad's MIDI notes to Bitwig Studio running on a desktop PC. There the MIDI was routed to Solo for the singing voice and Omnisphere for the background instruments.
After bringing the audio recording into Vegas Pro, I applied the Lurssen Mastering Console plug-in to the audio mix.
It's titled Portal.
