I was hoping I'd be able to get something that would act as both a firewire interface and as a control surface, just to minimize the amount of stuff I have to lug with me to sessions, etc. I've been looking at both the Tascam and Yamaha models, but I'm not sure the Yamaha has firewire capability.
If there isn't one out there, they should make it.
EDIT: Looks like the Tascam has firewire capability with a seperate card. Boy, it has a price tag on it, though.
