Doepfer A-140 ADSR Envelope Generator earthquaker therefore the unit provides monitoringOpen Box Unit Description Module A 140 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
