Description

Quad envelope generator

The Invictus Quad Function Generator comprises four function generators organized in two pairs. All four generators can operate independently or can be linked in pairs to generate more complex output voltages.
A switch selects one of three modes: Cycle, AR (Attack/Release), ASR (Attack/Sustain/Release).

Upon receiving a pulse, a generator’s output voltage ramps up to 10V at a rate determined by the sum of an applied control voltage and the setting of the attack time knob.

Impulse can be given manually using the trigger buttons or externally via the corresponding input jack. When in ASR mode, the voltage will stay high as long as the input pulse is maintained; when not in the ASR mode, or when the input pulse terminates, the output ramps down to 0V at a rate determined by the sum of the decay voltage and the setting of the decay knob. At the end of the Decay segment, a transient pulse appears at the pulse output.

The time range for both Attack and Decay is from 0,01 to 59 minutes.
In the Quadrature mode, generators 1 and 2 (or 3 and 4) operate in tandem with their functions shifted by ninety degrees in relation to each other.
