Reply to American Audio MXR14

Hi guys,
I'm new to the community and would like to know if anyone has any info on the MXR14 or if there is a decent review anywhere?

I like the look of this mixer and the 4 midi channels is exactly what I'm looking for to control Traktor, the only thing I don't like is there is no control over effects on the unit, does anyone know if the 2 x Mic channels could be mapped to control effects or are the analogue controls.

Thanks in advance
Steve
