Doepfer A-141-2 Voltage Controlled Envelope Generator

Module A-141-2 is the successor of the obsolete former VCADSR module A-141. Compared to the A-141 a lot of improvements and expansions have been added: common control voltage input for all time parameters (A/D/R), range switch for three different time ranges, inverted ADSR output, additional output with voltage controlled level (i.e. built in output VCA), digital outputs for  End of Attack (EOA) and End of Release (EOR), EOR is e.g. required for the VCLFO mode.

Features

• Voltage controlled envelope generator (ADSR type = Attack - Decay - Sustain - Release)
• Control knobs and CV inputs for all parameters
• Common CV input that modulates Attack, Decay and Release
• Slopes can be shaped between linear and exponential forms by feeding back the inverted output with the control voltage inputs
• 3 Position range switch from 1x to 10x to 100x
• End of Attack and End of Release gate outputs
• Master Envelope level CV input for velocity sensitivity
