Voice of Saturn Voltage Controlled Filter

   0 reviews  -  891 views

    This unit has a joystick or Voltage Controlled low-pass filter. It accepts two inputs that are summed and also voltage controllable (or knob). The joystick is modular, and can be patched to control or attenuate other equipment. Skill level: Intermediate... maybe beginner


    + Voltage Controlled Filter (VCF): Can be controlled with VC inputs (0-5V), joystick or knob (knob acts as an offset voltage). Low pass cutoff and resonance are controllable.

    + Two summing inputs with amplitude controllable by knob or VC (0-5V) input. Final output is similarly controllable.

    + X-Y Modular Joystick: By default the joystick X controls cutoff frequency and Y controls resonance. If a cable is plugged into either the X/Yout or cutoff/resonance VC inputs, the default joystick connection is broken, and it can be used to drive other equipment, or the VCAs for the I/O. If an outside VC or audio signal is connected to the X/Yin of the joystick, the joystick will attenuate that signal instead of the default 5V.

    Design Notes:

    Designed by Travis

    The Voice of Saturn VCF is based around the CEM 3372 Signal Processor chip. At one point ca. 2006 I wound up with a decent sized amount of these discontinued chips and I decided to design a filter module around them. I also had a great source for joysticks and loved that sort of user interface control. The result was the VoS VCF. Only ~40 of the full scale units were ever produced or made as a kit due to the limited number of joysticks and CEM chips but the module has also been released in a limited eurorack form. It features cv control over cutoff and resonance of the 24db 4 pole filter as well as cv controls for each of the two input VCAs and the output VCA.
