Is there another option to upgrade to video without using the TTM57? I really need a 19 inch mixer with more channels, plus I need video switching capabillity to feed external monitors and dual projectors. I know that there are other systems out there that don't require you use a specific mixer. A 12 inch mixer doesent do me any good in my rack and its not versatile enough for the type of multiple functions that I do. or is there an upgrade in the future that has a 19 mixer or a way that I can use my sl1?

thanks
