Vari-bandwidth VCF based on the Buchla 291, tho the CV sections are completely different and it uses a black box between the PCBs instead of dual vactrols. h...

This module is based on the Buchla 291 vari-bandwidth bandpass filter, tho it uses the blackbox rather than vactrols. The CV sections have been changed from the original circuit to a simpler version, it also has a Q pot, LP and HP outputs.
