Without jumping on the bandwagon I'd like to share with you how I mostly use the solution and what works/doesn't work for me.
I use my solution mostly in a live environment, and as such I use a nontouch monitor with a mouse because it has a much better pallet layout, both visually and practically by having more displayed on the screen rather than having to flick through pages on the MFKs. As ziglight has mentioned, the LCD screens are painfully slow to load for live shows and that you have to use your gut instincts that you're on the right page to select the next pallet for fast paced visuals.
I very occasionally use the desk as stand alone, usually when the programming has been done or it's a simple show with few changes.
My personal views, although I have created some great designs with the solution in live environments (and to the astonishment of some punters that I'm not using Avo!), I believe the desk is much better suited for theatre applications rather than live, high energy music events.
We've had an issue with our fader wheels (that I have mentioned to Z88) that when the PA is wound up and the bass is booming, it's really hard to control any of the fixture attributes with the wheels as they spin round by themselves adjusting whatever is selected. I've been told that this is a known issue and that it should be included in the latest update, which I'm still yet to download and install so it would be interesting to see if the issues persist.
