I haven't had chance to use every function, but so far this has far exceeded my expectations. We have just moved from Analogue to the QU24 & wish that I had done so sooner. no more effects racks & graphics to lug around. only downside is the small screen. But if you want bigger, then there's the GLD80, but so is the price! I probably could have got away with the QU16, but the QU24 has many more functions, not just 8 more channels. I haven't purchased the stagebox as yet, I'm sure it makes for a much quicker set-up, but I'll make do with my old multicore until I have some spare cash. but Its well worth getting the flightcase, to protect this little beauty . And one of the nicest bonuses has to be the ability to record multi tracks. All in all, a brilliantly functional bit of kit!
