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.
Zeeon: Using Midi CCs to control layers separately
Currently it isn't possible to assign different Midi CCs to the same parameter on different layers in Zeeon. E.g. CC 21 would control Osc1 Mix on layer 1, CC 22 would control Osc1 Mix on layer 2. Unfortunately, this doesn't seem to work.
Additionally you run into all kinds of problems because only the currently selected layer is receiving those messages – which means you can't control the original parameter anymore and you're starting to mess with the wrong one (especially when automating Zeeon).
Could you please investigate, @giku_beepstreet ? And ideally change the behaviour since it's not really useful at the moment? Thank you.
