THE CONTROLS
If you want "out of pitch" sounds for special effects, both
SPEED and WIDTH can be turned into the last third of their
range.
Adjusting INTENSITY
This has 3 different functions depending on the mode
setting…
In the CHORUS mode INTENSITY is a control
for the "notching" depth of the chorus effect. Turning the control
clock-wise increases the "notching" which is well suited for non
distorted single and rhythm guitars as well as most keyboards.
With chorus effects applied to song and generally when the
sound is more of a bass character, lower settings should be
used. When using the unit through returns on a mixing console
keep the INTENSITY control at maximum.
