COSM GUITAR Chapter 9 Parameters Guide
Chapter 9
* With the GR-300 selected as the COSM guitar, expression of sounds
may become unstable when the Alternate Tuning 12STR is set to ON
or when pitches are shifted excessively.
SENS (
Sensitivity)
0–100
Adjusts the input sensitivity for the enve-
lope modulation function. As the value is
raised, the change from the envelope modu-
lation broadens with even weaker picking.
Confirm the change in the tone as you
make the adjustment. Try setting the
value near 0, then gradually raise it as
you pick a string. Setting the attack time
to 0 makes the changes easier to confirm.
ATTACK
0–100
Adjusts the attack time for the change in the en-
velope modulation produced by picking. Rais-
ing the value slows the attack for this change.
PITCH A/PITCH A FINE,
PITCH B/PITCH B FINE
These adjust the amount of pitch shift.
* This is enabled when the PITCH SW parameter is set to anything other
than OFF.
* The final amount of shift in the pitch is the sum of the pitch shift set
with PITCH and PITCH FINE.
PITCH A
PITCH B
-12–+12
This sets the amount of shift in pitch from
the original sound in semitone increments.
A setting of -12 lowers the pitch one octave,
while +12 raises the pitch one octave.
PITCH A FINE
PITCH B FINE
-50–+50
This finely adjusts the pitch. A setting of -50
lowers the pitch one semitone; +50 raises the
pitch by one semitone.
You can use this FINE setting effectively in
the DUET feature that follows.
PITCH SW (Pitch Switch)
This setting allows you to switch on and off the pitch shift, which en-
ables the pitch of the HEXA-VCO sound to shift in response to the
pitch of the sound caused by the string’s vibration.
* PITCH SHIFT is applied only to the HEXA-VCO, not the HEXA-
DISTORTION. Set MODE to VCO or V+D when using the pitch shift function.
OFF
The pitch of the original source sound is un-
changed.
A The shift in pitch set with PITCH A and
PITCH A FINE is applied.
B The shift in pitch set with PITCH B and
PITCH B FINE is applied.
DUET
OFF, ON
When DUET is set to ON, then in addition to
the HEXA-VCO, a sawtooth wave is played
at the same pitches as the source sound,
adding greater breadth to the sound.
Setting HEXA-VCO pitch shifts to values
such as PITCH+/-12 (up or down an
octave), +/-7 (perfect fifth), or +/-5
(perfect fourth) produces a thicker sound
like that from a synthesizer.
You can add further depth to the sound by
setting PITCH FINE to +/-5, thus slightly
shifting the pitch of the HEXA-VCO.
Parameter/
Range
Explanation
SWEEP
This SWEEP function smoothly changes the amount of pitch shift
when the amount of pitch shift is changed with PITCH SW.
SW (Switch)
OFF, ON
Turns the SWEEP function on/off.
PITCH SW is normally controlled after
the settings for the operation of PITCH
SW are made in Control Assign.
* The SWEEP function is enabled when the
amount of shift in the pitch of the HEXA-
VCO is changed through the operation of
PITCH SW. It is not activated in response to
changes in the pitch of the input when the
amount of pitch shift does not change. No
effect is produced when the SWEEP SW in
RISE and FALL is set to OFF.
RISE
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.
When set to zero, the pitch changes instant-
ly; at higher values, the pitch rises more
slowly.
FALL
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.
When set to zero, the pitch changes instantly;
at higher values, the pitch falls more slowly.
VIBRATO
You can apply an electronic vibrato effect to the HEXA-VCO.
SW (Switch)
OFF, ON
Turns the VIBRATO function on/off.
By setting VIBRATO SW as the function
to be controlled in Control Assign and
then switching the VIBRATO SW to ON
as you are playing, you can apply
stronger vibrato at whatever point in a
performance you want.
* You cannot apply vibrato to the HEXA-
DISTORTION.
RATE
0–100
This adjusts the rate of the vibrato. Raising
the value increases the rate.
DEPTH
0–100
This adjusts the depth of the vibrato. No vi-
brato is added when the value is set to 0. The
vibrato deepens as the value is raised.
