Module A-140-1 is an envelope generator, and, since it puts out control voltages, counts as one of the modulation devices in a modular system. As soon as the gate input receives sufficient voltage, the ADSR generates a variable voltage, changing in time, called an envelope. This varying voltage is output in normal (positive) and inverted form, and can be used, eg., for voltage controlled modulation of a VCO, VCF, or VCA, or for processing other modules' inputs and outputs.

The shape of the envelope is governed by four parameters: Attack, Decay, Sustain and Release.

Key Features:

• Three-position toggle switch to select one of three time ranges
• The ADSR generates a variable voltage, changing in time, called an envelope
• The envelope can also be re-triggered each time a trigger signal is sensed at the Retrig. input socket, when the gate is still open.
