Modulation speed: The rate of
modulation. Slow times create a quiet
beat; high speeds sound like vibrato or,
in extreme cases, like it's under water.
The type of modulation may be selected
using the buttons.
Waveform selection: sine, square (sqre) and random (rand) are available. The sine wave is
suitable for rhythmic, quiet sounds. A square wave sounds quite drastic and very rhythmic.
Random mode is useful for ambient sounds or sound landscapes, since the progressions
are not foreseeable and can add an interesting accent to the sound.
The sync button snaps the speed to the song tempo. Alternately, you can set the
modulation tempo manually in Hz.
Tone/Filter Section
The low and high-pass filters limit the signal for each voice/delay unit.
Feedback: Set how strongly the signal in each unit is fed back to itself here. High values
produce a typical, cutting flanger sound. What makes CORVEX stand out from many other
digital devices is that high feedback rates will not create overmodulation. For each delay
unit, the signal is fed at a saturation level to create a soft, analog-sounding threshold.
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
