Description

Unleash the rhythmic potential of your modular setup with the Doepfer A-142-4 Quad Decay. This compact Eurorack module offers four AD envelope generators, making it a versatile tool for shaping percussive sounds and dynamic modulation effects. With attack times preset at a snappy 3ms—reminiscent of the iconic TB303, yet adjustable from 1ms to 15ms—you have the flexibility to craft everything from sharp stabs to smooth fades. The decay times span from a lightning-fast 2ms to a more languid 2 seconds, ideal for diverse sonic explorations.

The A-142-4 doesn’t just excel in functionality; it’s also a space-saver, occupying only 8HP of your rack. Each output is equipped with an LED for visual feedback, and the module features normalized triggering inputs for streamlined operation. Whether you're producing short blips, long crashes, or anything in between, this module's simplicity and precision allow you to focus on creativity without getting lost in complexity. Perfect for both seasoned modular enthusiasts and those just starting their Eurorack journey, the Doepfer A-142-4 is a reliable addition to any modular synthesizer setup.
