Explanation
MIX LEVEL
COSM GUITAR
0–100 Specifies the level of the COSM GUITAR.
NORMAL PU (Normal Pickup)
0–100 Adjusts the volume of the normal pickup.

Range
Explanation
NS (Noise Suppressor)
This effect reduces the noise and hum picked up by guitar pickups.
Since it suppresses the noise in synchronization with the envelope of
the guitar sound (the way in which the guitar sound decays over
time), it has very little effect on the guitar sound, and does not harm
the natural character of the sound.
SW (Noise Suppressor Switch)
OFF, ON Turns the NS effect on/off.
THRSH (Threshold)
0–100 Adjust this parameter as appropriate for the
volume of the noise. If the noise level is
high, a higher setting is appropriate. If the
noise level is low, a lower setting is appro-
priate. Adjust this value until the decay of
the guitar sound is as natural as possible.
REL (Release)
0–100 Adjusts the amount of time from the point at
which application of the noise suppressor
begins to when the volume is fully attenuat-
ed.
Parameter/
Range
Explanation
MODE
This setting determines whether the HEXA-VCO (sawtooth wave) or the
HEXA-DISTORTION (rectangular wave) is played, or if both are played.
VCO The HEXA-VCO sound is played.
V+D The HEXA-VCO and HEXA-DISTORTION
sounds are played simultaneously.
DIST The HEXA-DISTORTION sound is played.
LEVEL
0–100 Sets the volume. With a setting of 0, there
will be no sound.
COMP (Compression)
OFF, ON When this is set to ON, the HEXA-VCO’s
decay time is extended.
When ENV MOD SW is set to ON, the VCF (vari-
able frequency filter) decay time is also extended
* The HEXA-DISTORTION decay time is not
extended.
CUTOFF FREQ (Cutoff Frequency)
0–100 Adjusts the cutoff frequency, setting the
brightness (hardness) of the sound. The sound
gets brighter (harder) as the value is raised.
RESO (Resonance)
0–100 Adjusts the resonance (distinctiveness of the
sound). As the value is increased, sounds in
the frequency range near the cutoff frequen-
cy are boosted, making the sound more dis-
tinctive and unique.
ENV MOD (Envelope Modulation)
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.
SW (Switch)
OFF Envelope modulation is not used.
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 low frequencies to high.
Setting the cutoff frequency to an
extremely high value makes the effect
difficult to discern.
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 high frequencies to low.
Setting the cutoff frequency to a
relatively high value makes the effect
easier to discern.
