Available now! The Doepfer A-140 ADSR Envelope Generator⠀
⠀
The Doepfer 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 processing other modules’ inputs and outputs.⠀
⠀
The shape of the envelope is governed by four parameters. Attack, Decay, Sustain and Release. The envelope is started (triggered) by a gate signal either from the INT. Gate voltage on the system bus, or, if a signal is put into it, from the gate input socket. The envelope can also be re-triggered, ie start from scratch again, each time a trigger signal is sensed at the Retrig. Input socket, when the gate is still open.⠀
