This is the center piece of my small but growing modular; you can either control 4 events (by columns, which are assigned to both gate CV and continuous CV) or change 3 values across 4 constant levels (by rows), or a combination thereof. The little trimmer pot lets you adjust to your own skin resistance, to achieve more gradual transients.
It's a very creative module overall, and lots of fun.
The hardware feels solid overall: knobs and jacks are high quality.
