The SPDIF I/O is linked directly to the main mix, 3/4, 5/6, 7/8 or ADAT. I use SPDIF for my TC Electronics M300 as an effects loop. Universal Control defaults to Main mix. This is a major inconvenience, as i am routing a send via SPDIF to M300, and out of M300 to SPDIF into a channel input. I must find and empty mix bus, or sacrifice an ADAT Channel. I want SPDIF to work like all of the other I/O Channels, not automatically assigned to a mix bus.
