A Drambo native looper without using any external utilities. Works standalone because it loads Drambo as an AUv3 plugin inside Drambo.
This is because Drambo does not suport local MIDI loopback (yet?).
Track 2 is set up to record from external audio which can be either your iPad/iPhone microphone or an external audio interface.
Mind the audio feedback!
Turn the output volume down before you start!
