The function of each parameter

VIBRATO

This effect creates vibrato by slightly modulating the pitch.
This effect can be used in the "GUITAR MULTI 1" algorithm
when the MOD "SELECT" parameter is set to "VB."
* For details on MOD (Modulation) settings, refer to "About
MOD " (p.47).
RATE
This adjusts the rate of the vibrato.
* If this is set to BPM, the MASTER BPM (p.105) setting for
each patch will determine the rate, so that the effect sound will
match the song tempo. However, if the BPM value is high, the
effect will synchronize to 1/2 or 1/4 of the BPM.
DEPTH
This adjusts the depth of the vibrato.
TRIGGER
This parameter works as a switch that turns on the vibrato
effect.
When it is set to ON, the vibrato effect will be obtained
according to the RISE TIME setting.
* This effect assumes that the trigger will be turned on with a foot
switch for attaining the vibrato effect.
RISE TIME
This sets the time passing from the moment the trigger is
turned on until the set vibrato is obtained.
TRIGGER ON/OFF
To switch the trigger on/off of the vibrato using the foot
switch (FS-5U, DP-2 (Roland), etc.), set "Control Assign"
(p. 33) as follows.
< ASSIGN1: ON >

VOCAL CANCELER

When a stereo source is being input from CD or DAT etc.,
this cancels the sound which is located in the stereo center,
such as the vocal or bass.
EFFECT
This parameter turns the vocal canceller effect on/off.
BALANCE
If the sound that you wish to cancel is not located in the
center, find the point at which it is most effectively cancelled.
When the value is set to "50," the sound that is located at the
center will be muted.
RANGE LOW
Specify the lower limit of the frequency range from which
you wish to cancel a sound. Use this setting when you wish
to decrease the volume of the vocal without affecting a low-
frequency instrument (such as bass) located in the center.
RANGE HIGH
Specify the upper limit of the frequency range from which
you wish to cancel a sound. Use this setting when you wish
to decrease the volume of the vocal without affecting a high-
frequency instrument located in the center.

VOCODER

This is a 10 band vocoder. A clear sound that was not
possible with conventional vocoders can be obtained. Input
an instrumental sound into the left channel, and a voice into
the right channel.
EFFECT
This parameter turns the vocoder effect on/off.
ENVELOPE
Select how the sound will be produced.
SHARP:
The human voice will be emphasized.
SOFT:
The instrumental sound will be emphasized.
LONG:
A vintage sound with long decay will be produced.
PAN MODE
Select MONO, STEREO, L->R or R->L.
