Speaking about a mixer...

I'm thinking about using this mixer:

The master sound radius 4V, maybe not the mixer you would come up first with but from my perspective not a bad choice.
I need at least 3 channels (Digitakt, Modular and Sirin). It has a 3 band EQ on each channel which is very handy, each channel can be cued. It has an AUX send/return on all the 4 channels which can be pre/post fader. It is truly analog and rotary which I want to have since I started DJ-ing. Beautiful piece of gear!
