Quadra & Expander Manual
more complex voice how to use more. For example, another AD envelope could be used to
control the modulation index of a two VCO FM patch. You can use envelopes to control the
amount an LFO controls the filter via another VCA, or use a multed VCA in parallel with the final
VCA to act as an effect send. You can see how with a little imagination and a lot of VCAs you
will quickly run out of envelope generators, especially once you start designing percussive
sounds.
Linear Versus Exponential Shapes
Linear Mode
(switch to the
right) - The Quadra makes
straight lines as shown by
the examples in the left
column of this illustration.
This is best used with
exponential VCAs. The
fastest envelope times are
achieved when in linear
mode.
Exponential Mode
(switch to
the left) - The Quadra
creates a musical curved
shape found on many classic
envelope generators (as
shown by the examples in
the right column of this
illustration). This is best used
with linear VCAs. The results
in this mode tend to have a more plucked character.
