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.
Purple Cycloid / No Hardware! SpaceCraft and Noise
I hope Mark @deltaVaudio will listen to this one. Both engines of SpaceCraft with samples from my own tracks. I loved learning how to play this remarkable instrument a bit. Thank you Mark!
Also my first experiment with MPE and Roli Noise (halfway thru). Another thrill as to its potential for me. There is a Seaboard block in my future now. The Noise lead line supported by SwarPlug Bansari. BASSalicious, two tracks of Brazilian Drum Machine and a touch of iSymphonic strings.
And, no hardware keyboard! All on the screen.
