Group Parameter Value Description
PITCH
PITCH SW
Switches the pitch shift setting of the hexa-VCO that responds to the pitch of the string vibrations.
* Pitch shift applies only to the hexa-VCO; it does not apply to hexa-distortion.
If you want to use the pitch shift function, set MODE to “VCO” or “V+D.”
OFF The pitch of the original sound will be unmodied.
A The pitch shift specied by PITCH A and PITCH A FINE will be applied.
B The pitch shift specied by PITCH B and PITCH B FINE will be applied.
PITCH A/B
Adjusts the amount of pitch shift.
* This is eective when PITCH SW is set to anything other than “OFF.”
* The nal amount of pitch shift is the sum of PITCH and PITCH FINE.
-12–+12
Species the amount of pitch shift for PITCH A/B relative to the original pitch, in
semitones. A setting of “-12” is one octave down, and a setting of “+12” is one octave
up.
PITCH A/B FINE
Adjusts the amount of pitch shift.
* This is eective when PITCH SW is other than “OFF.”
* The nal amount of pitch shift is the sum of PITCH and PITCH FINE.
-50–+50
Applies a ne adjustment to the PITCH A/B pitch. A setting of “-50” is half a semitone
lower, and “+50” is half a semitone higher. This ne setting allows DUET to be used
eectively.
DUET 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 fth), 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.
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 SW OFF, ON
Turns the Sweep function on/o.
MEMO
Normally, you’ll use Control Assign to control PITCH SW, and use the control to operate
PITCH SW.
The Sweep function is eective when you operate PITCH SW to change the pitch shift
amount for the hexa-VCO.
It does not operate on changes that occur in the input pitch while the pitch shift
amount is unchanged.
SWEEP RISE and SWEEP FALL have no eect if SWEEP SW is “OFF.”
SWEEP RISE 0–100
Adjusts the time over which movement to a higher pitch will occur.
If this is “0,” the change will occur instantly; higher values produce slower change.
SWEEP FALL 0–100
Adjusts the time over which movement to a lower pitch will occur.
If this is “0,” the change will occur instantly; higher values produce slower change.
VIBRATO
Allows you to apply electronic vibrato to the hexa-VCO.
VIBRATO SW OFF, ON
Turns the vibrato eect on/o.
MEMO
If you make Control Assign settings to control VIBRATO SW, you’ll be able to add
powerful vibrato by turning VIBRATO SW “ON” when desired during your performance.
* You can’t apply vibrato to the hexa-distortion.
VIBRATO RATE 0–100
Species the vibrato rate.
Higher values produce faster vibrato.
VIBRATO DEPTH 0–100
Species the vibrato depth.
With a setting of “0” there will be no vibrato. Higher values produce deeper vibrato.
