Z4000 NS VC-EG

A voltage-controlled analogue ADSR envelope generator with a built-in CV processor. Attack, Decay, Sustain and Release each have a knob and a control-voltage input; the first half of the A, D and R knobs' travel is given to millisecond settings. ATTEN. scales and inverts the output, and DEVIATER, under voltage control at VC, mirrors or clips it; a lamp shows the level in both polarities. An ATK SLOPE switch picks a logarithmic or exponential attack, SHOOT fires the envelope by hand, and RTRIG retriggers it for legato playing.
