Product Description

Doepfer A-140, ADSR Envelope Generator

• The module A-140 is a envelope generator and since it delivers control voltages
• belongs to the modulation-modules. As soon as the ADSR is triggered at gate-input
• it generates an adjustable control signal called the envelope. This envelope is present on its outputs in normal and inverted S-form and can be used e.g. for modulation of VCO
• VCF and VCA modules as well as for transient and decay oscillations of other modules. The S-form of the envelope is unambiguously defined by four parameters
• attack
• decay
• sustain and release. The ADSR is triggered with a gate-signal at gate-input and provides the possibility of a retrigger-Function
• i.e. the envelope will be restarted every time a trigger signal is present at the retrigger-socket while the gate is active.

In connection with the comparator-module A-167 a free run "ADSR-LFO" can be realised.
