Making LFO Settings

This section explains the LFO setting screens.

Waveform (LFO Waveform)

Selects the waveform of the LFO.

Value

SIN: Sine wave

TRI: Triangle wave

SAW: Sawtooth wave

SQR: Square wave

RND: Random wave

TRP: Trapezoidal wave

S&H: Sample & Hold wave (one time per cycle, LFO value is

changed)

CHAOS: Chaos wave

“LFO” in the lower right of the screen shows a wave graphic that corresponds to the current settings.

Offset (LFO Offset)

Raises or lowers the LFO waveform relative to the central value. Positive (+) settings will move the waveform so that modulation will occur from the central value upward. Negative (-) settings will move the waveform so that modulation will occur from the central value downward.

Value: -100, -50, 0, +50, +100

Key Sync (LFO Key Sync Switch)

This specifies whether the LFO cycle will be synchronized to begin when the key is pressed (ON) or not (OFF).

Value: OFF, ON

Delay Time (LFO Delay Time)

Delay Time (LFO Delay Time) specifies the time elapsed before the LFO effect is applied (the effect continues) after the key is pressed (or released).

Value: 0–127

After referring to “How to Apply the LFO” (p. 49), change the setting until the desired effect is achieved.

Creating a Patch

Rate (LFO Rate) ★◆

Adjusts the modulation rate, or speed, of the LFO.

Value: 0–127, Note

LFO Rate sets the beat length for the synchronized tempo when the tempo that specifies the LFO cycle (Patch Tempo) is synchronized with the tempo set in a external sequencer.

(Example)

For a tempo of 120 (120 quarter notes occur in 1 minute (60 seconds))

Setting	Delay time	Patch
(half note)	1 second (60 / 60 =1 (second))
		a
(quarter note)	0.5 seconds (60 / 120= 0.5 (seconds))
		Creating
(eighth note)	0.25 seconds (60 / 240= 0.25 (seconds))

This setting will be ignored if the Waveform parameter is set to “CHAOS.”

“LFO” in the lower right of the screen shows a diagram of the wave cycle that corresponds to the current settings.

Fade Mode (LFO Fade Mode)

Specifies how the LFO will be applied.

Value: ON <<, ON >>, OFF <<, OFF >>

After referring to “How to Apply the LFO” (p. 49), change the setting until the desired effect is achieved.

Fade Time (LFO Fade Time)

Specifies the time over which the LFO amplitude will reach the maximum (minimum).

Value: 0–127

After referring to “How to Apply the LFO” (p. 49), change the setting until the desired effect is achieved.

How to Apply the LFO

●Apply the LFO gradually after the key is pressed

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.
