I got this because for some reason there are no good eurorack mixers with effects sends and pans that are reasonably priced. This one fit exactly what I needed. The build quality is A+. There are 2 issues though.
1-The layout is just dumb. They didn't lay it out like a typical sequencer as a grid. HATE THAT.
2-The mute buttons are cramped in click switches. Not a major thing, but I can't really perform with mutes like that.
Good mixer for what it is otherwise. I'd recommend it just for the sends alone. If you have detailed needs, you're going to have to whip out a grand or simply use external gear.
