Switched Capacitor VCF driven by its own VCO and MORE
The CGS57P combines the unique features of Ken Stone's CGS57 BI-N-TIC filter with the CGS56 Gate Converter and CGS04 Mixer.
This allows the CGS57P to output the first 4 divisions of the sub-oscillator from individual jacks. In addition a custom mix of the sub-oscillators is output from a fifth jack.
The CGS57P provides input from up to 7 different sub-oscillation divisions.
Audio signals input into the filter are combined with divided output from the the internal oscillator. Alternatively an external audio signal can also be fed into the filter as a secondary audio source.
The filter has an almost organic feel with textures and colors practically morphing on their own. It is an extremely different and exciting module.
