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.
Quick iWavestation question
Just bought iWavestation (on sale for 16.99 Euros). The 6 cards and KLC seem to be included without buying the IAP now.
But a few patches don't work? For instance, Card 1, Number 0, Piano 16' doesn't play anything on either side of the split at B3/C4. But most of the Card 1 patches do work.
Maybe this is normal and I should just buy the IAP and everything will work?
