Q109

Envelope Generator

Aug 2014

The Q109 Envelope Generator is one of the basic modules every synthesizer

must have. It generates a voltage envelope in response to a gate signal from a

keyboard, oscillator or other source. The envelope is used to control amplifiers,

filters, oscillators and other modules. The operator has complete manual control

over Attack time, Decay time, Sustain level, and Release time. A manual gate

button can be used to trigger the Envelope Generator at any time, and an LED

gives a visual indication of the output level.
