I recorded my Moog Minifooger MF Drive at hundreds of settings and built a plugin from those recordings, LadderDrive. In each round you hear the same loop twice: once through the real pedal and once through the plugin, in a random order. Switch between A and B as often as you like while it plays, then tell me which one is the pedal.

Everything loops seamlessly, and A and B play in sync, so you can switch mid-note. Nothing is uploaded until you choose to send your answers at the end.
