Parameter Range Description
LFO Rate 1/1 Sys to 1/32 Sys, 0.0Hz
to 20.0Hz
Controls the rate of the modulation applied to the delay time of the
chorus.
LFO Shape Triangle, Sine, Sawtooth,
Square, Asym, Step
Determines the shape that the LFO will use for pitch modulation.
LFO Phase -180deg to +180deg Controls the relative phase between left and right LFOs.
Chorus Depth 0.0ms to 25.0ms Controls the amount of modulation.
Chorus Center 0.0ms to 50.0ms Controls the four delay times within the chorus. Adjusting this parameter
will change the tonal character of the chorus.
Rev Mix Full Dry to Full Wet Controls the Dry/Wet mix of the reverb.
Decay 0.0sec to 10.0sec Controls the amount of time it takes for the reverberation to decay away
to a very low level after the input signal stops.
HF Damping 100Hz to 21.2kHz Controls the rate of attenuation of high frequencies in the decay of the
reverberation. As natural reverb decays, some high frequencies tend to
get absorbed by the environment. Increasing the value of this parameter
will gradually filter out (dampen) more and more high frequency energy.
HF Bandwidth 100Hz to 21.2kHz The high frequency bandwidth acts as a low pass filter on the signal
going into the reverb, controlling the amount of high frequencies that will
pass into the effect. The higher the setting, the more high frequencies are
allowed to pass.
Diffusion 1 0 to 100 Smears the input signal transients, to diffuse and smooth the sound.
Lower values will cause impulse sounds to appear as a series of discrete
echoes, while higher values tend to increase the smear (smoother
sounding with fewer discrete echoes). We recommend settings of 50 for
starters.
Diffusion 2 0 to 100 This parameter, similar to and in series with Diffusion1, performs the
same way but controls lower frequency ranges. Experiment with different
levels between the diffusion parameters to find the settings that are right
for your source.
Definition 0 to 100 Controls the rate at which echo density is increased with time. Setting
this parameter too high can cause the echo density to build at a rate which
exceeds the decay rate.
