and, yes I agree with the above.
Send should be pre-fader on EXT1 & EXT2
In this manner you would never be forced to ALWAYS blend the source channel with A separate return FX channel using either EXT1 OR EXT2
OR At least an option in the set up menu for the V10 mixer - "SEND pre/post fader" option
Kindly make a consideration for this important request.
WELL DONE, FANTASTIC MIXER!
