Editing the TONE Track
STRUCT
Structure lets you play two partials as a pair.
By using partial 1 or 3 (the carrier) to modulate the other partial 2 or
4 (the modulator), you can create a wide range of tonal characters.
Parameter Value
Partial 2 is used to modulate the sound of partial 1.

Explanation
off
This implements the oscillator sync function
that is provided by analog synthesizers.
The oscillator of partial 1 is reset at pitch
cycles of partial 2.
* This is available only when OSC Type is Virtual
Analog or PCM Sync.
This implements the ring modulator that is
provided by analog synthesizers.
The output of partial 2 is multiplied with
partial 1.
& "RING" (p. 63)
This implements the cross modulation
function that is provided by analog
synthesizers.
The output of partial 2 is applied as the
pitch of partial 1.
& "XMOD" (p. 63)
Adjusts the volume of OSC 1/3.
Adjusts the volume of OSC 2/4.
Adjusts the volume of ring modulation.
Adjusts the depth of cross modulation.
Explanation
Specifies the depth of the pitch envelope.
Higher values make the pitch envelope
produce greater change. Negative "-" values
invert the shape of the envelope.
If the OSC Type is other than VA, this is
limited to ±63.
Specifies the time over which the initial
value changes to the maximum value after
the note starts.
Specifies the time over which the SUSTAIN
value is reached following the ATTACK.
Specifies the sustain value of the pitch
envelope.
LFO
Here you can make LFO settings.

them.

Explanation
Sine wave

Sawtooth wave (negative polarity)
Square wave
Random wave
Trapezoidal wave
Sample and Hold wave (changes the LFO
value once every cycle)
Sine wave modified by a VSIN chaos wave.
The amplitude of a sine wave is randomly
changed once every cycle.
Modified sine wave. The amplitude of the
sine wave is randomly varied once every
cycle.
A waveform generated from data specified
by LFO Step 1–16.
This produces a fixed pattern of stepped
change like a step modulator.
You can edit this in the TONE PARTIAL EDIT
screen.
& Refer to "Detailed Sound Editing" (p.
43).
This is available if Rate Sync is OFF.
It specifies the LFO cycle regardless of the
tempo. Higher values shorten the LFO
cycle.
Specifies the depth at which the LFO is
applied to the cutoff frequency.
Specifies the depth at which the LFO is
applied to pitch.
* If OSC Type is other than Virtual Analog, the
range is limited to -63–+63.
Specifies the depth at which the LFO is
applied to volume.
Specifies the depth at which the LFO is
applied to pan.
Explanation
Specifies the time over which the initial
value changes to the maximum value after
the key is pressed.
Specifies the time over which the SUSTAIN
value is reached following the ATTACK.
Specifies the sustain value of the filter
envelope.
Specifies the time over which the minimum
value is reached after the key is released.
Explanation
Specifies the control-source signal.
* If you specify SycCtrl 1–4, you can use the
panel [FILTER] [MOD] [FX] knobs to control
the parameters.
Specifies the parameter that is controlled.
& For an explanation of each parameter,
refer to "Parameter List" (p. 61).
Specifies the amount (depth) by which the
parameter is varied.
