I love this, particularly when coupled with the 6 switches for mutes.
Fantastic Euclidean rhythm generator and loads of fun to perform with on the fly. Instructions (a little complicated to follow at first!), but essentially three modes to this. (1) where you want to place your beats (2) where you want the first beat to start and (3) the length of your pattern, and once you get the hang of it, really easy to adjust on the fly and create completely novel inter-related polyrhythmic patterns that just bring your drums/percussion to life. Can also save presets (which I am doing with a view to playing out live soonish!)
I couple it with the VPME Quad Drum, which is also a wonderful thing, and a couple of other percussion sources, and it is also useful to send out weird clocks to other units in my case. Highly recommended.
