Doepfer A-142-4 Quad Decay

The Doepfer A-142-4 Quad Decay is a versatile Eurorack module featuring four independent decay envelopes. Each decay envelope is triggered by a gate or trigger signal and produces a control curve that falls from its peak back to zero over an adjustable decay time. This makes it a perfect tool for modulation tasks requiring a quick and simple amplitude or parameter decay.

Thanks to its compact design and four channels in one module, the A-142-4 allows users to perform multiple simultaneous modulations without taking up extra rack space. It’s ideal for driving VCAs, filters, or other modules accepting envelope inputs, adding flexibility and efficiency to your modular synth setup.
