the more high frequencies are allowed to pass. This functions like a tone control on a guitar.
LF DECAY TIME Range: -99 to +99
Acts like a tone control and will boost (when set to a positive value) or cut (when set to a negative
value) the rate at which low frequencies will decay.
DEFINITION Range: 00 to 99
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. A general rule of
thumb is this: DEFINITION should not exceed the LF DECAY TIME added to the DECAY TIME.
DIFFUSION-1 Range: 00 to 99
Smears the input signal transients to diffuse and smooth the sound. Lower values 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 Range: 00 to 99
This parameter, similar to and in series with DIFFUSION-1, performs the same way but controls
lower-frequency ranges. Experiment with different levels between the diffuser parameters to
find the settings that are right for your source.
REFL-1 TIME Range: 0000 to 0120 ms
Controls the delay time for the first pre-echo. Pre-echoes are the first sounds that have been
reflected back from the walls or reflective “live” surfaces. Higher values delay the diffused signal
more.
LEVEL Range: 00 to 99
Controls the level of the first pre-echo. This pre-level controls the echo send to the DEFINITION.
SEND Range: 00 to 99
Controls the level of the first pre-echo, with the echo routed directly to the output.
REFL-2 TIME Range: 0000 to 0120 ms
Controls the delay time for the second pre-echo.
LEVEL Range: 0 to 99
Controls the level of the second pre-echo. As a signal continues to bounce off the different
reflective surfaces (walls), it decreases in volume. Set this parameter to a lower value than REFL-
1 LEVEL to create a natural sounding echo.
SEND Range: 00 to 99
Controls the level of the second pre-echo, with the echo routed directly to the output.
DETUNE - RATE Range: 00 to 99
Controls the LFO rate of detuning introduced into the reverberation decay. Detuning creates a
slight oscillating pitch shift into the decay, giving it a more natural sound by breaking up
resonant nodes.
DEPTH Range: 00 to 99
Controls the depth of the detuning, that is, how much the pitch will change. Low values yield a
metallic sound. Some sounds may require very low values, while others sound more natural
with higher values.
