511C Voltage Controlled Envelope Generator
The VOLTAGE CONTROLLED ENVELOPE GENERATOR in typical ADSR-Style with five voltage controlled parameters with associat- ed attenuator knobs: attack time, decay time, sustain level, release time and envelope amplitude. The input jack for the amount of contour control is internally connected to +10 volt.
The time parameters range from 1 ms to ap- prox. 20 s (at full mo- dulation). The time control voltage inputs are daisy chained. Control range is 0-10 v. Two LEDs serve as indicator lamps for ’gate pulse present‘ and for the envelope output.
