Solution - Solution XL VS FLX - FLX S 48 in General Discussion Posted March 28 · Report reply Hi Eric, As someone who's just moved from a Solution to a FLX, I've found the following. The Solution feels like ZerOS has been shoe horned to fit the old leap frog layout, where the FLX has been designed around the ZerOS system. There are a number of functions already not available on the Solution for example the multi point colour picker across fixtures. This will only increase as new developments are released, such as easier control of subfixtures and the splitting down of beams and shapes. The older architecture inside the Solution does lag when pushed, we haven't had this issue with the FLX. Saying that I do miss the screens for virtual labelling on the playbacks on the Solution and the ability to create your own layouts on desktops. Saying this the FLX wins hands down, more MFFs (multi functional faders) and easy to use, very happy with our purchase. I hope this is of some help.
