The audio input of the Steiner Synthasystem VCF is followed by a level control. Via a switch, users can choose the module’s high-pass, band-pass or low-pass mode. Two large, very handy potentiometers allow users to comfortably adjust cutoff and resonance. For cutoff modulations, two CV inputs plus attenuators were implemented. Thanks to two outputs, filtered audio material can be sent to several other circuits in parallel.
