F5: Reverb/Chorus/DSP Effect
● REVERB PARAMETER EDIT
When the REVERB TYPE parameters are se-
lected as described above, the PARAMETER EDIT
LCD button will appear, pressing this button gives
you access to the individual reverb parameters for
the currently selected reverb type. Use the LCD [▲/
▼] control below the number corresponding to the
parameter you want to edit. Press the
TYPE LCD
button to return to the REVERB TYPE parameters
when done.
1. REVERB TIME Range: 0.3 … 30 sec.
Sets the amount of time it takes for the reverb sound to decay by 60 dB (virtually to silence).
2. DIFFUSION Range: 0 … 10
Adjusts the left-right “spread” of the reverb sound. The higher the value the greater the spread.
3. INITIAL DELAY Range: 0 … 63
The length of the initial delay before the actual reverb sound begins (in milliseconds). The higher the value the
longer the initial delay.
4. HPF CUTOFF Range: Thru, 22Hz … 8.0kHz
The cutoff frequency of the high-pass filter applied to the reverb sound. No filter is applied when set to “Thru”.
5. LPF CUTOFF Range: 1.0kHz … 18kHz, Thru
The cutoff frequency of the low-pass filter applied to the reverb sound. No filter is applied when set to “Thru”.
NOTES
• The default parameters will automatically be reselected
whenever a new reverb type is selected.
● REVERB DEPTH
Independently sets the depth of the selected
reverb effect for the multi pads, accompaniment,
left voice, right 1 voice, right 2 voice, and lead voice
If the REVERB DEPTH parameters are not showing
on the lower section of the display, press the DEPTH
LCD button. Use the M.PAD, ACMP, LEFT, R1,
R2, and LEAD LCD [▲/▼] controls to set the depth
of the reverb effect as required for the corresponding
parts. The depth range is from “0” (no reverb effect)
to “100” (maximum reverb depth).
NOTES
• In addition to the graphic depth controls directly above the
LCD [ ▲ / ▼ ] controls, reverb depth for each part is repre-
sented by a vertical bar to the right of the REVERB DEPTH
parameter in the upper section of the display. The longer
the bar, the greater the reverb depth.
• When a new reverb type is selected, the preset depth
value for that type is automatically recalled.
• Each part and voice has a preset depth value and range
over which the depth can be varied. Depth variations may
therefore not have the same audible effect with all voices.
