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.
[FS] U-he Repro (Prophet / Pro-One) - $75
I purchased the recent U-he bundle, and am selling my previous license to Repro. My price matches the sale price, for those who may have missed it. It's an amazing synth, and well worth the $149 regular price. $75 PayPal friends and family, or you pay the fees. License transfer wil be handled by U-he, and I hear they are very quick to respond. This is a desktop Au/VST, not for iOS.
"To complete a transfer, all we need is the new owner’s full name and email address. If they already are an existing u-he customer, please send us the name and email address for their u-he account. You can use the form on our support page to begin the process."
