I bought this as an upgrade to a Chauvet Obey 40, just in time as the Chauvet gave the ghost on me setting up for a charity gig in June, Luckily had the Stairville mixer with me, spent a quick hour programming my 30 odd lights (All LED) and a couple of moving heads, Fog and Haze to save the day. It took me a while since then to get my head round the FX programs but they have become a useful addition to my show now. The USB function is brilliant as I work with a couple of bands on a regular basis and this allows me to program and save Scenes and chases to match their tracks and reload them for gigs...I will be getting more moving heads to use the Pan and Tilt and FX functions to better effect. Great little desk for smaller rigs like mine, real value for money
