Explanation
Specifies the time over which the LFO
amplitude will reach the maximum
(minimum).
* After referring to "How to Apply the LFO" (p.
72), change the setting until the desired effect
is achieved.
Specifies whether the LFO cycle will be
synchronized to begin when the key is
pressed (ON) or not (OFF).
Specifies how deeply the LFO will affect pitch.
* If OSC Type is other than VirtualAnalog, the
range is limited to -63–+63.
Specifies how deeply the LFO will affect the
cutoff frequency.
Specifies how deeply the LFO will affect the
volume.
Specifies how deeply the LFO will affect the
pan.
M E MO
Positive (+) and negative (-) value for the Depth
parameter result in differing kinds of change
in pitch and volume. For example, if you set
the Depth parameter to a positive (+) value
for one partial, and set another partial to the
same numerical value, but make it negative (-),
the modulation phase for the two partials will
be the reverse of each other. This allows you
to shift back and forth between two different
partials, or combine it with the Pan setting to
cyclically change the location of the sound
image.

Explanation
This is effective if Waveform is STEP.
Specifies the step size that is looped.
This is effective if Waveform is STEP.
Specify the Depth value of each step.
If you want to specify this in pitch scale
degrees (100 cents), the settings are as
follows.
Pitch Depth: 51, Step: multiples of 6
1
... up to one octave of change
Pitch Depth: 74, Step: multiples of 3
2
... up to two octaves of change
Pitch Depth: 89, Step: multiples of 2
3
... up to three octaves of change
* If OSC Type is not VirtualAnalog, the Pitch Depth
setting range is limited to -63–+63, so only "1"
above is possible.
Specifies the type of curve at each step.
