i posted a similar question a little while ago and didn't get too much response.
i've found it difficult to get totally satisfactory mixes straight out the box.
the eq's are ok, but they're not very intuitive. and to really fix up all your
mix you have to re-sample things, which means that the eq settings you
used for your re-sample on the hats line may not match once you've
compressed and eq'd the kick etc etc.
so really, my advice (and the advice i was given when raising the same q)
is to mix in your DAW and then re-sample sounds and work from there.
you can get ok mixes tho... don't let my pessimism stop you trying!
i've found since i've been runnin my MP using the individual outs and going
into a mixer my sounds have gotten better.
let us know how you go, what methods you try etc. be keen to hear
