What about if I connected the USB jacks between the two boards (an M32R and an M18)? I could get a stage box instead of the M18 for the same price, presumably with higher quality preamps, and a simpler way to interface, but this is a really big difference. Having two separate consoles to mix 32 channels OR two smaller stages, AND a backup in case my primary console fails, are both HUGE benefits .
I have an M32R, and rather than buy a "stage box" I was considering just buying an M18 for 16 more inputs. Has anyone used this in this way? They both have "Ultranet" ethernet jacks so I was expecting I could route the M18's inputs to the M32R, but I wanted to confirm that this works.
