I've only just started delving beneath the surface, but so far I've managed to add switches which...

Drop the pitch of the samples by half. Revoice the preset patterns. Layer voices so the samples cut-off abruptly. (As the polyphony gets used off... first note cutoff I think they call it.)

More importantly, I've also worked out a combination of switches which give grungy distorted glitch rhythms reminiscent of the Aphex Twin. (kind of)

Out of the box... crap. But get inside the box and you may be pleasantly surprised.

Got mine off ebay. They turn up on there daily, so I wouldn't expect to pay more than about £10 to £12.
