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.
Going Nuts With Drambo
Sometimes I go totally nuts with Drambo…
In this super basic example the graphical modulators output is passed thru a low-pass filter to modulate the pitch of the oscillator which is passed thru a bit-reducer before the amp.
The graphical modulators y-axis is set to 12 and the pitch-modulation depth to 0.125(ie. 1 octave).
There’s no better tool for creating chip-tune type sounds than Drambo
(But it can do way, way more than that).
