Any recommendations on a compact analogue mixer without sliders?
I'm looking for something that has a knob matrix interface, like
this and which is also possible to get hold on.
The rougher the better, so rather metal than plastic casing.
A simple stupid summing device would do, with 4 or more inputs.
Maybe something more erotic than the Behringer MX400.
I'd consider building something myself, but probably saving my health by asking here first.
