Group Parameter Value Description
TONE
MODE #
Species 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 Hexa-distortion will sound.
COMP OFF, ON
If this is “ON,” the decay time of the hexa-VCO will be extended. If ENV MOD SW is “ON,”
the decay time of the VCF (variable frequency lter) will also be extended.
* The decay time of the hexa-distortion will not be extended.
FILTER CUTOFF # 0–100
Adjusts the VCF cuto frequency, specifying the brightness of the sound. Higher
settings will make the sound brighter.
FILTER RESO # 0–100
Adjusts the VCF resonance (unique characteristics). Higher settings will boost the
sound in the region of the cuto frequency, producing a sound with more distinctive
characteristics.
ENV
This automatically varies the VCF cuto frequency according to the amplitude of the string vibrations. This causes a wah-like tonal change each time you
pluck the string.
ENV MOD SW
OFF The envelope modulator will not be used.
ON
Each time you pluck the string, the VCF cuto frequency will move from high toward
low, producing a “wah” eect.
MEMO
Extremely high cuto frequency settings will make this eect dicult to discern.
INV
Each time you pluck the string, the VCF cuto frequency will move from low toward
high, producing an “oo-ahh” that is the opposite of the “wah” eect.
MEMO
Fairly high cuto frequency settings will make this eect easier to discern.
ENV MOD SENS 0–100
Adjusts the input sensitivity of the envelope modulation. Higher settings of this value
will increase the range of envelope modulation that occurs when you pluck a string
softly.
MEMO
Listen to how the sound is aected while you adjust this parameter. Start with the
setting at about “0,” and play while you gradually raise the value.
Setting ENV MOD ATTACK to “0” will make it easier to hear the change.
ENV MOD ATTACK 0–100
Adjusts the attack time of the envelope modulation that occurs when you play a
string.
Higher values produce a slower attack.
