565 v3 CP

CP Format Quadruple Quantizer

QUAD QUANTIZER featuring four independent quantizer circuits forces variable control voltages into semitone intervals (1/12 volt) over a bipolar input voltage range of more than twenty octaves (255 semitones).
Gate pulses fed into the “Gate In“- jack trigger the quantizer. An “open“ gate input quantizes, i. e. if no gate jacks are patched. The four gate-ins are passed through, one plugged IN 1 feeds IN 2 to IN 4 as well.
The gate outputs supply a pulse, when- ever the (quantized) output voltage changes. The most recent quantized value remains preserved until the next quantization will occur.
