Envelopes
Envelope generators are essential ingredients for sound design. Without
them a sound would remain static. It would simply start and stop for the
duration of a key press, which is neither particularly exciting nor the way
sounds work that surround us in our daily lives, be it in crowded places or
while hiking in a remote location.
Envelope generators help us to add dynamic movement to a sound
insofar as they allow us to determine how a sound evolves over time.
Typically, envelope generators are routed to filters and amplifiers to
change the harmonic content and the volume of a sound through several
durational stages.
The envelope section.
The Super 6’s envelopes can be routed to multiple destinations including
the VCF (see page 44), the VCA (see page 47) and the DDS Modulator
Both envelopes contain four stages known as attack, decay, sustain and
release, or ADSR if you fancy acronyms. In addition to that, envelope 1
(ENV 1) also features a so-called hold stage that allows you to delay the
moment the attack stage will begin after you pressed a key.
