LFO is immediately added after the key is
pressed, after which the effect gradually
fades.
fig.05-56.e
Fade Mode: ON-OUT
Fade Time: The time over which the LFO amplitude will
reach the minimum after the Delay Time has elapsed.
Delay Time The time that the LFO will continue after the
keyboard is played.
LFO is gradually added after the key is
released.
fig.05-57.e
Fade Mode: OFF-IN
Fade Time: The time over which the LFO amplitude will
reach the maximum after the Delay Time has elapsed.
Delay Time: The time from when the keyboard is released
until the LFO begins to be applied.
LFO is added from the time the key is
pressed to the time it is released, after
which the effect gradually fades.
fig.05-58.e
Fade Mode: OFF-OUT
Fade Time: The time over which the LFO amplitude will
reach the minimum after the Delay Time has elapsed.
Delay Time: The time that the LFO will continue after the
keyboard is released.
LFO DEPTH 1:2
fig.05-59
For each item, specify the amount of the LFO effect.
The effect produced by modulating the pitch is known as
vibrato.
The effect produced by modulating the cutoff frequency
is known as wah.
The effect produced by modulating the volume is known
as tremolo.
Two values are displayed for each parameter listed
below. The left one is for LFO1, and the right one is for
LFO2.
Pitch (Pitch LFO Depth 1, 2)
Specifies how deeply the LFO will affect pitch.
TVF (TVF LFO Depth 1, 2)
Specifies how deeply the LFO will affect the cutoff
frequency.
TVA (TVA LFO Depth 1, 2)
Specifies how deeply the LFO will affect the volume.
Pan (Pan LFO Depth 1, 2)
Specifies how deeply the LFO will affect the pan.
Positive (+) and negative (-) settings 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 Tone, and set
another Tone to the same numerical value, but make it
negative (-), the modulation phase for the two Tones will
be the reverse of each other. This allows you to shift back
and forth between two different Tones, or combine it
with the Pan setting to cyclically change the location of
the sound image.
When any value from Type 210 is selected for the Type
parameter (PATCH/COMMON/STRUCT) in the Pan
parameter settings, the output of Tones 1 and 2 are
joined in Tone 2, and the output of Tones 3 and 4 are
joined in Tone 4. For this reason, the setting of Tone 1
will follow the setting of Tone 2, and the setting of Tone
3 will follow the setting of Tone 4 (p. 73).
