Two independant Contour Envelope Generators in a single 12hp 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%u2019s
The contour generators played a larger part in the sound of the
Model D than many people realise. There are two factors that make them
unique, firstly the exponential slope when is used in conjunction with
the (near) linear slope of the original VCA which is responsible for
the famous Model D %u201cpunch%u201d.
Secondly, the re-trigger behaviour is
quite unique, multiple retriggering increases the output level so that
either the volume increases incrementally or the filter opens
incrementally with each extra key press.
We have added independant Decay switches for each individual
Contour Generator rather than the shared switch on the original
synthesiser, these switches change the Contour response from AD (switch
up) to ADSD mode (switch down).
