It certainly helps to be able to change programs etc with one feet!
Although this for me is only a 'stop-gap' as I'll be investing in a decent dmx controller soon. I would certainly recommend this piece of kit if you're in a band and operating the lights at the same time as playing an instrument, just don't get the two confused as the lights may not produce that 'overdrive' or 'phase' effect you're after! :)
Seriously though, a sound bit of kit which does the job flicking through program scenes and sound to light. Go get one for your setup, you won't be disappointed. Better still, if you're in the market for lights and stands too, go for the bundle deal. Worth every centimo.
