[sdiy] Unique sounding modules that can't have voltage control?

The EML 101 had a center-tapped pot with low, band, and high pass outputs connected to each side and that center tap. Very natual 3-way crossfade that is not voltage controlled and "can't be" 

I suppose the equivalent could be dialed in with 3 VCAs, but that's a lot of circuit compared to the ease of that one sneaky pot, and it would take some fiddling to get it responding the same

Cheers,
Chris McDowell

Or the other way round: the voltage change is linear but there is a "de-linearizing" circuit in the controlled module. Example: expo-converter in V/Oct. controlled VCOs.
