im 90% sure ive done it with 2 different cards. we deffo had 2 for a surround sound recording, whether or not they were the same card i dunno. but they were connected with SPDIF.

could have been done with some workaround tho... 2 machines, or a load of analogue routing or something. anyways i havnt slept yet again so i cant think


so im conceding :)
