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.
I need an iPad interface
I'm searching for an audio/MIDI interface for iPad Air v3 (lightning port) that is NOT bus powered. I want to be able to record an electric guitar, overdub a vocal, then overdub a stereo synth. I would also like the ability to direct monitor.
There is a Zoom U-24 which can be battery powered. I understand when two sources are input they sum to mono for monitoring. Still, workable I think.
There is the IK Duo. I don't know how well it fits my criteria. I see that direct monitoring is a switch, so no way to blend the input source with the iPad sound while recording?
There is the Roland Rubix 44. Maybe more than I need, but it has what I want. But it gets bad reviews for stability.
More inputs and outputs would be fine. But I don't need fancy routing, and I don't want to HAVE to use software to get it working (RME, new Steinberg UR-RT).
What else is there? I don't care about included software, and I could spend up to $600 (but less is better) as long as it's a good product. Please help and thank you for any suggestions!
