AJH - Dual EG Contour Silver

The AJH Synth ‘MiniMod Contour Generators’ features two independent Contour Envelope Generators in a single 12 HP wide Eurorack module. These are very accurate replicas of the Model D contour generators, with identical circuitry and component values running on the correct +9.3V and -10v supply voltages of the original; so they exactly replicate the original envelope response along  with all of it eccentricities. Extra features include manual trigger buttons  and envelope status LED’s.

The contour generators played a larger part in the sound of the Model D than many people realize. There are two factors that make them unique, firstly the exponential slope when used in conjunction with the (near) linear slope of the original VCA which is responsible for the famous Model D “punch”. Secondly, the re-trigger behavior is quite unique, multiple re-triggering increases the output level so that either the volume increases incrementally or the filter opens incrementally with each extra key press.

AJH Synth has added independent Decay switches for each individual Contour Generator rather than the shared switch on the original synthesizer, these switches change the Contour response from AD (switch up) to ADSD mode (switch down).
