Diffusion: This is one of the most interesting parameters of CORVEX, and it's
rather unusual for this type of effect. Normally, larger delays are audible as
discreet echoes. Using "diffusion" softens the signal in each voice, scattering
its shape. In extreme cases and with sufficiently high "time" values, even
reverb-like sounds are produced. This enables a small room to be replicated
using "time", "voices" & "span", and "diffusion" can be applied to simulate the
natural properties of scattering signals over surfaces. With high feedback
values, simply modulate the pitch a little (the small controller below "time") to
break up the creation of comb artifacts resulting from static repetitions.
Complex: Usually each voice pairing functions in "PingPong" mode, i.e. the left
channel is reflected to the right and vice-versa. In "Complex" mode, the
feedback & diffusion parameters are combined, which produces a quite
chaotic sound. In "Complex" mode, each one of the eight possible voices
affects every other one, i.e. echo repetitions ensure that diffusion is even
faster. In this case, the maximum number of voices make drastic spatial
sounds possible. For this reason, CORVEX even manages to eclipse some
specialized reverb effects...
After this overview of the main parameters, we still need to explain the other
small controllers on the lower row.
As mentioned above, this involves an intensity setting for the modulation
depth: each of these faders specifies how much LFO affects the relevant
parameter above it.
The following applies:
 The envelope of the LFO affects the "time" parameter directly, meaning that
activation of the round LED in the modulation section results in increased
delay times.
 The LFO also affects all other parameters to the right directly. To the left, the
inverse value of the modulation envelope is taken. For example, if you have
selected "sine" as the waveform, the inverse curve shape will correspond to a
sine wave which is mirrored along the X-axis. In practice, this results in a
temporal modulation shift of exactly half of one period length.
Basically, the modulation values combine with the settings of the main
controller. For example, to get a rhythmic stereo width introduction, set the
stereo width control to 0%. Switch on "sync", adjust the "speed" to "1/4", and
set the small fader for the modulation target (stereo width) to the right. This
opens the stereo picture to maximum every fourth note. Now turn the small
controller below "stereo width" to the left: the stereo picture now plays on the
off beats. This is where the inverse envelope is effective and the mentioned
temporal shift is kept intact.
