Very okay compact dual vco. Negatives: no simultaneous different waveform outputs, no sinewave, no knob for wide range pitch. Its primarily oriented towards conservative chromatic pitch use. What I like primarily is the fact that there are two of them, so I can do crosswise FM, also given the fact that each vco has 3 contol inputs with attenuation. Hm, in the conservative orientation I'm a sucker for synchronised fm-timbres and this module does most of that totally elegantly, apart from the fact that I cannot sweep either oscillators pitch on the module itself over a big range. Using external cv the pitch goes from ultra- to subsonic so there are work arounds. I have some wide range vco's so this one is a welcome addition.
