How hard would it be to build a mixer with multiple spdif sends instead of analog ones? That's always been a bug in my bum, I have all this really nice digital gear (roland v-synth, virus ti, kurzweil mangler, others...) but I can only use 1 spdif at a time, so out of spite I actually use none.
The TI works better via usb, but I digress.
I'm going to build that mfos kit eventually since all Ray's stuff is awesome. Check out his 8 stage phaser.
