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.
Tutorial: Complex evolving rhythms with Perforator and Rozeta
1) Set your synth to play a sustained note or chord.
2) Put two Perforators on it. Give each Perforator a different step length: one odd number and one even number. This is probably all you need for most tracks, but if you want to get really out there:
3) For even more complexity and evolution, send a Rozeta LFO to the "Steps" parameter for each Perforator. Use a different LFO for each Perforator, and set the two LFOs to different speeds so that they run out of sync with each other. Medium low speeds will probably work best. This can get very out of control if you let it. Dial back the amount of LFO modulation, and give Perforator a pattern to play for the high step numbers.
4) Send a Rozeta LFO square wave to AUM's volume fader for even more interest. Also try modulating the square wave. You can also send it to your synth's filter cutoff for rhythmic tonal interest.
These are good techniques for adding rhythmic interest to pedal points or sustained chordal pads (or tonal interest, if you apply it to the filter instead of the gate).
It would be good if Rozeta LFO had a pulse width wave, but it doesn't. Even just a 33% and 66% option that you could sync to tempo would be a nice alternative to the square wave.
