The perfect controller for the 0-Coast, and feels tactile and intuitive to play. Might(?) not be ideal as a controller for live performance, but as a compositional tool it's a dream. I bought the 0-Coast and 0-Ctrl because I'd read the 2 in combination described as a (more) affordable version of a Buchla Music Easel, and after playing for a couple of weeks that feels kind of right to me.
