Moog THE SOURCE User Manual

1. Attack time: Time taken for voltage to increase from zero (initiated by trigger) to maximum.
2. Decay time: Time taken for voltage to decrease from maximum to sustain level.
3. Sustain level: A static voltage amount that, once initiated, continues as long as a key, or keys, is held down.
4. Release: Time taken for voltage to drop from sustain level to zero after the key is released.
Different settings of these times and levels will produce markedly different contours. Some examples are shown below:

LOUDNESS CONTOUR » FILTER CONTOUR
It is important to remember that although the two contour generators can output radically different contour patterns,
the loudness contour will have "priority" over the filter contour. If the filter is going through a long, involved contour,
and the VCA has already closed, it makes no difference, because no audio signal is heard.
The output of the filter contour generator can be attenuated, or lessened, by adjusting the Contour Amount control
(described in the Filter section on page 32). The voltage from the loudness contour generator to the VCA is not
attenuated.
