VL Version 2
Freq.
¯
Sets the speed of modulation and therefore the rate of symphonic effect variation.
Depth
¯
Sets the depth of modulation. Higher values produce deeper modulation and there-
fore a more pronounced symphonic effect.
Diffusion
¯
Diffusion determines the amount of stereo "spread". The higher the value the
greater the spread. When set to "0" the symphonic effect is a centered monaural signal.
Lo-Fi
¯
This parameter can be used to give the symphonic effect a more analog feel. Higher
values produce a smoother effect in the high-frequency range.
Wet/Dry Balance
¯
Sets the balance between the direct ("dry") and effect ("wet") sound. Higher values
produce a greater proportion of effect sound in relation to direct sound.
