OK, think i got the problem solved, the "pre-fader" thingy works :)

but now, when i'm linking the 8 digi channels back to the PC to record down, there dont seem to be any effects/eq on the recorded stuff. i've applied on the mixing desk some distortion on the bass and eq'd kick a bit, but i just get normal kick and lame bass when it's recorded...
could always record back via the desk monitor out and sound card in
