■
LFO
.............................................................................................................................................................................................................
The LFO parameters set the LFO (Low Fre-
quency Oscillator) to produce cyclic pitch and am-
plitude modulation.
PMD: Sets the phase modulation depth. Higher
values produce deeper modulation.
AMD: Sets the amplitude modulation depth. Higher
values produce deeper modulation.
SPEED: Sets the speed of LFO variation.
WAVE: Sets the waveform of the LFO: TRI (trian-
gular) or SAW (sawtooth).
■
DELAY VIB
..................................................................
Delay Vibrato is a vibrato effect based on LFO
modulation which has a variable delay between the
time a key is played and the beginning of the vibrato
effect.
TIME: Sets the delay between key-on and the begin-
ning of LFO modulation. No delay is produced
when TIME is set to its minimum value. In this
case, only normal vibrato is produced (this has no
relation to the RATE value).
RATE: Sets the rate at which LFO phase modulation is
applied after the delay time — i.e. how long it takes
to reach maximum modulation level after modula-
tion begins. The AMD has no RATE parameters.
■
REVERB DEPTH
...........................................................................................................................................................................
Sets the depth of the reverb effect. The higher the
value the greater the reverb depth.
■
CHORUS DEPTH
.................................................
Sets the depth of the chorus effect. The higher the
value the greater the chorus depth.
■
DSP EFFECT
...........................................................
Use the TYPE LCD [▲/▼] controls to select a
DSP EFFECT type, and the DEPTH LCD [▲/▼]
control to set the depth of the selected DSP effect.
For some DSP effect types the DEPTH parameter is
fixed at “100” and cannot be changed.
NOTES
• Depending upon the selected DSP EFFECT type, some
PAN parameters may not function.
