AJH Synth Mini Mod Contour Generators

The AJH Synth Mini Mod Contour Generators is a 12 hp Eurorack module that houses two independent contour envelope generators based directly on the classic Model D design, using the same circuitry, component values, and original supply voltages to preserve the exact response and quirks of the originals. The result is the distinctive envelope behaviour that helped define the Model D’s feel and impact. Each envelope includes a manual trigger button and a status LED for quick visual feedback.

These contours are a big part of the classic “punch”, thanks to their exponential shape working against the near-linear VCA response, and their unusual retrigger behaviour, where repeated triggers progressively increase the envelope level. Unlike the original, each envelope has its own Decay mode switch, allowing you to select between AD and ADSD operation independently.

Includes ribbon cable.
