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.
lightweight channel strip for live looping w/ mic'd audio
i want to have a lightweight channel strip (eq, compress/expand) app I can put a mic input through before going into loopy. lightweight because i want minimum latency and need to have 2 separately-processed mono inputs simultaneously (e.g. cello and vox).
AUFX:PeakQ looks nice but i am having trouble with finding a compressor/expander -- there seem to be lots of mastering-oriented apps but that doesn't seem like a good idea for single voices.
the DAW apps of course have channel strip plugs, but i am worried they will use too much processor overhead and i'll have to have big buffers -- want to keep it to <10ms latency with iPhone 5S
