Doepfer A-171-2 Voltage Controlled Slew Limiter II

The Doepfer A-171-2 is a voltage-controlled slew limiter inspired by classic Serge modular circuits, offering a highly flexible tool for shaping and processing control voltages. It can serve as a slew limiter, envelope generator, portamento controller, or even a simple function generator or LFO depending on how it’s patched.

You get manual and CV control over rise and fall times, allowing dynamic control from other modulation sources. A built-in gate output triggers when the output passes a threshold, expanding its use in timing-sensitive patches. Whether you're smoothing CV signals, generating exponential glides, or building complex modulation chains, the A-171-2 is a feature-rich and affordable utility module for any Eurorack system.
