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.
Qneo / Voicisynth SDK Audiobus support
This is what's on the Qneo's Facebook wall :
IMPORTANT NOTICE TO VOICE SYNTH AUDIOBUS USERS
Audiobus support will be discontinued soon, as it does not meet the stability standards we want to offer our customers. The audiobus SDK in Voice Synth is currently malfunctioning. We advise to use Apple’s inter-app audio (IAA), which is free, integrated in iOS, and stable since introduction.
For continued audiobus support, please ask the audiobus developers to support IAA. Then all your IAA-enabled apps become audiobus compatible, while their stability will not be compromised.
Could you tell us what you think about that ?
(I'm just asking...)
