State variable 12 db/oct VCF (old version)

State variable 12 db/oct VCF

Adapted from non Eurorack module by Ray Wilson. This is his earlier state variable VCF from the "Oldies But Goodies" modules list.

"This will add a ton of timbres to your bag of tricks. This filter is also known as a Universal Active Filter. You get simultaneous High Pass, Band Pass, and Low Pass filtering. You can, of course, cascade two of these to obtain higher order filtering. The control voltage portion is just about straight from a Bernie Hutchins design. I love this filter. I built two into a module and am really pleased with the results. Now my synth has two of my low pass filters and two of these... I'm in filter heaven."
