Creating a Patch
1:/2:Key Trigger (LFO1/LFO2 Key Trigger)
This specifies whether the LFO cycle will be synchronized to begin
when the key is pressed (ON) or not (OFF).
Value: OFF, ON
1:/2:Pitch Depth (LFO1/LFO2 Pitch Depth)
Specifies how deeply the LFO will affect pitch.
Value: -63 +63
1:/2:TVF Depth (LFO1/LFO2 TVF Depth)
Specifies how deeply the LFO will affect the cutoff frequency.
Value: -63 +63
1:/2:TVA Depth (LFO1/LFO2 TVA Depth)
Specifies how deeply the LFO will affect the volume.
Value: -63 +63
1:/2:Pan Depth (LFO1/LFO2 Pan Depth)
Specifies how deeply the LFO will affect the pan.
Value: -63 +63
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 the Structure parameter (PATCH/TMT) is set to any
value from 2 through 10, the output of tones 1 and 2 will be
combined into tone 2, and the output of tones 3 and 4 will be
combined into tone 4. This applies to the 1:/2:Pan Depth
parameter settings. For this reason, tone 1 will follow the settings
of tone 2, and tone 3 will follow the settings of tone 4 (p. 56).
How to Apply the LFO
Apply the LFO gradually after the key is pressed
fig.LFO-1.e
Fade Mode: ON <
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 played until the
LFO begins to be applied.
Apply the LFO immediately when the key is
pressed, and then gradually begin to
decrease the effect
fig.LFO-2.e
Fade Mode: ON >
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.
Apply the LFO gradually after the key is
released
fig.LFO-3.e
Fade Mode: OFF <
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.
Apply the LFO from when the key is pressed
until it is released, and gradually begin to
decrease the effect when the key is released
fig.LFO-4.e
Fade Mode: OFF >
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.
