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 crackles/DSM spikes
Very recently, AUM has been causing crackles and showing high DSP for the first 30 seconds I open a preset. I know that it's just been within the last week that something has changed because I use these presets all the time and they have never caused crackling like this before. What's odd is that the crackles and DSP settle down to "normal" after those 30 seconds of spikiness. I have systematically deleted apps to make sure it's not an app I updated that is the culprit. No dice. I can bring a preset all the way down to one app and I still see the spike for 30 seconds (albeit with no crackles because the DSP isn't relatively high). Two questions: (1) any ideas about what could be causing this? (2) If I delete and reinstall AUM, will I lose all my presets? (ie should I back them all up?)
