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.
AUM "cutting out"
I've been using AUM as my primary performance tool, with my instrument and powered speakers connected to the iPad through a Scarlett 2i4 audio interface. It works flawlessly except that the audio occasionally "cuts out" at random. I thought originally that it was because I had my Peterson tuner app also running, but that turns out not to be the case. The signal is interrupted only momentarily, like less than a second, and for practice it's not a big deal at all, but I do hope to use this setup for live performance someday, and it will definitely be embarrassing if my gear decides to go silent for a half-second at random moments!!
The DSP figure never seems to be indicating that the system is being stressed in any way (it always seems to hover between 30 and 40% on this iPad Air 4th-gen.) My signal chain isn't all that complex. The signal is stereo in two channels with a RoughRider compressor, 4Pockets VisualEQConsole, AudioKit Rack reverb and a Baby Audio Magic Switch chorus on each channel.
Anyone seen this before? Any suggestions on what I can do to find the problem or eliminate it?
