She is really complte except the classic phono / line and mic aures, it provides a monitor output, and MIDI output for other devices synchronyser tempo.
The effects section is nice, and offers quite a parameter.
In addition, the rack is bte.
I do not see what you could add, oh yes! rglage a crossfader (dmontable)

UTILIZATION

Easy as good evening!

SOUNDS

It sounds good, ask the eq a little practice, the first mix can spend more difficult than usual but you get done quickly.

OVERALL OPINION

I used all the time I mix (few years) for applications Exceeds sometimes the simple mix between 2 MKII, sampler, synth, everything is pass!
A really friendly and versatile machine trs.
