hehe, it was a bit of a trick question, since @simeon suggested that if Arturia were going to make something as a module, they would have already made a VCF or VCO, whereas I was curious if this might be one that they would module-ize, since it already has a significant patchbay.
Anyway,
I wouldn’t be upset if they made one…I’m not convinced that the Steiner-Parker character lends itself to poly sounds, but I could certainly be wrong. I guess I could layer my 'Brute to try it out. A Polybrute would have to be pretty close in price to something like a Prophet Rev2, though, and I’d probably go for the DSI in that case, personally. Curtis and Steiner-Parker filters share some characteristics (which I largely like - Mopho X4 and Microbrute are 2 out of my 3 hardware synths), but I’m sure they could make something plenty unique.
