Solidly built and with the ability to preprogramme the lower 24 channels as different chases over a number of fixtures and run them together in any combination at the flick of a fader makes busking a convincing lightshow a pretty straightforward affair with no prep time required even for a band you haven't seen before. Add step, button, adjustable pre programmed independent chase speed and audio step triggering and you are not really short of anything much, one hell of a lot of bang for your buck. The only drawbacks are that even though you have 4 separate pages of chases, you can't copy and paste chases between pages to copy elements of shows (not that I have found anyway!), and no USB to back up or load / save shows, so if you are full, you have to delete one page and reprogramme the new show from first principles step by step. You also need to power it up once a month for a couple of hours to charge the onboard backup battery so it doesn't forget all your chases, but apart from that it does one hell of a lot more than far more expensive desks, and can't fault it at the price.
