The Behringer FCB1010 even in stock form can send messages on different channels, up to 5 PC changes on different channels at a time if I recall correctly. Honestly, almost everything the new firmware offers can be programmed into an FCB with an UNO. If you need control of several devices, you're going to be doing some programming anyway. I'm sticking with the regular UNO chip for now unless something compels me otherwise.
Will, I know and I'm for now sticking with the stock FCB010/UNO ( been using it for almost 2 years) . The Tuner on the floor would be pretty cool,but I can live without it. I may still order the cool glow in the dark stickers from LABRAT
