(In BASS MODE) Parameters
GR-300/ANALOG GR
Parameter
Value
Explanation
MODE
Specifies whether to sound the hexa-VCO
(sawtooth wave), the hexa-distortion (square wave),
or both.
VCO
Only the hexa-VCO will sound.
V+D
The hexa-VCO and hexa-distortion
will sound together.
DIST
Only the hexa-distortion will sound.
COMP SW
*1
OFF, ON
If this is “ON,” the decay time of the
hexa-VCO will be extended.
CUTOFF
0–100
Adjusts the cutoff frequency at
which the filter cuts off the sound’s
harmonic components.
RESONANCE
0–100
Adjusts the amount of filter
resonance (distinctiveness of the
sound) used.
ENV MOD SW
This automatically changes the VCF cutoff
frequency according to the amplitude of the string
vibration. This allows you to change the tone with a
wah-like effect each time you pick a string.
OFF
Turns envelope modulation off.
ON
This causes the VCF cutoff
frequency to change from a high to
low frequency each time the string
is picked.
This produces a wah-like effect,
with the sound going from high
frequencies to low.
INV
As opposed to the ON setting, this
allows you to have the VCF cutoff
frequency change from a low to
high frequency each time the string
is picked.
This produces a reverse wah-like
effect, with the sound going from
low frequencies to high.
ENV MOD
SENS
0–100
Adjusts the input sensitivity of
the envelope modulation. As the
value is raised, the change from
the envelope modulation broadens
with even weaker picking.
ENV MOD
ATTACK
0–100
Adjusts the attack time for the
change in the envelope modulation
produced by picking.
Raising the value slows the attack
for this change.
PITCH SW
*1
OFF, A, B
This setting allows you to switch
A, B and OFF the pitch shift, which
enables the pitch of the HEXA-VCO
sound to shift in response.
* Pitch shift applies only to the
hexa-VCO; it does not apply to
hexa-distortion.
PITCH A
PITCH B
*1
-12–+12
This sets the amount of shift in
pitch from the original sound in
semitone increments.
Parameter
Value
Explanation
FINE A
FINE B
*1
-50–+50
This finely adjusts the pitch. -50 is
half a semitone down; +50 is half a
semitone up.
DUET SW
*1
OFF, ON
If this is “ON,” a sawtooth wave
at the same pitch as the original
sound will be added to the hexa-
VCO, making the sound richer.
MEMO
By setting the hexa-VCO’s pitch
shift to a PITCH setting such as
+/-12 (an octave up/down), +/- 7
(a perfect fifth), or +/-5 (a perfect
fourth), you can create thick,
synthesizer-like sounds.
By setting PITCH FINE to about “+/-
5” to slightly skew the pitch shift
of the hexa-VCO, you can give the
sound greater depth.
SWEEP SW
*1
OFF, ON
This is a Sweep function that
smoothly changes the amount of
shift when you use PITCH SW to
vary the amount of pitch shift.
SWEEP RISE
*1
0–100
Adjusts the amount of time for
the pitch to shift when the PITCH
SW parameter is switched and the
sound changes to a higher pitch.
If this is “0,” the change will occur
instantly; higher values produce
slower change.
SWEEP FALL
*1
0–100
Adjusts the amount of time for
the pitch to shift when the PITCH
SW parameter is switched and the
sound changes to a lower pitch.
If this is “0,” the change will occur
instantly; higher values produce
slower change.
VIBRATO SW
*1
OFF, ON
Allows you to apply electronic
vibrato to the hexa-VCO.
VIBRATO RATE
*1
0–100
Adjusts the rate of the vibrato.
VIBRATO
DEPTH
*1
0–100
Adjusts the depth of the vibrato.
LOW CUT
FLAT, 20.0
Hz–16.0 kHz
Cuts the frequency region below
the specified frequency. When FLAT
is selected, the low cut filter will
have no effect.
HIGH CUT
20.0 Hz–16.0
kHz, FLAT
Cuts the frequency region above
the specified frequency. When FLAT
is selected, the high cut filter will
have no effect.
*1 Valid when the MODE is set to VCO or V+D.
