A-142-1 Voltage Controlled Decay / Gate

Doepfer A-142-1

Module 142-1 is a compact envelope generator for eurorack modular synthesizer systems. Much like the TB-303, the only temporal parameter featured is Decay, which can be adjusted manually with the dedicated knob or remotely via control voltage. Additionally, the module emits a gate and inverse gate sourced from the envelope signal—effectively providing users with a voltage controlled gate. A corresponding LED provides visual indication of the gate status.
