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.
OT: WebCassette by Klevgrand
"We're constantly exploring new areas, trying out new technologies and concepts. Sometimes, even useful stuff comes out. WebCassette is an online cassette deck emulation, and we're proud as peacocks over the result. Use the Eject button to load your own audio track!"
I really Really hope this becomes available as an AU/App and if you feel the same please let the wonderful Klevgrand team know!
