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.
OT: Random number generator with timed outputs [SOLVED]
There are a plethora of RNGs for both IOS and Android, but they all require interaction to generate a number (you have to press the screen every time you want a new number).
Do you know of any RNG that can be set up to output a new value according to a specified interval (ie, generate a new value every 30 seconds)?
