This thing is really, really fat, I didn't expect it to sound that good, actually. I run my VSTS thought it and they definitely get a second life!
Also, it's got a very narrow, clinical resonance, which can sing with a pure sine, can be modulated and can create cool stereo effect when using a pair like I do.
It's also quite tweakable on the CV side. The only drawback are very small CV amount knobs, but I can still operate them efficiently.
