Thanks but I'm looking for first and foremost a mixer of digital signals, a switcher on top would be nice but not necessary. The goal here is to combine game audio (in an FPS basically just the announcer and environmental effects) with music from a different source.

The only other way I can think to implement it is to add an expensive pro external soundcard to connect to a laptop, then output to DAC. Only that setup would be a bit cumbersome and still require the proper card/interface.

Looking around I might have to take you up on that offer.

Thanks! The feature set looks awesome. I went through all of Roland's/Behringer's/etc. products and they have nothing to fill that niche outside of multi-thousand dollar consoles. Especially surprising given the iPod generation DJ market.
