Vintage style 12dB state variable VCF
This is a state variable filter which has a very simple design and is easy to build. The filter behaves similarly to vintage filters of the 1970s and 1980s and this is further reflected in the presentation of the controls. The two pole filter has -12dB per octave roll-off for high pass and low pass and a -12 db wide (-6dB either side) bandpass output.
It has voltage control of cutoff frequency (F). F and Q are adjustable with panel controls and the frequency is also adjustable from external sources using two F CV inputs, one of which can provide modulation in the positive or negative direction using a built in attenuverter.
The response of the filter can be switched in or out of bandpass mode. When bandpass mode is off the filter can be continuously swept between Low Pass, Notch and High Pass responses.
Comprehensive manuals, parts lists and component shopping carts are provided in the documentation link for building, testing and using the module.
Module is available as a DIY project only.
