PITCH ENV

VELO

Use this to set how much the pitch envelope changes in response to 

how hard you play the keys. Set this to a “+” value to make the pitch 

envelope respond more when you play harder, and set this to a “-” 

value to make it respond less when you play harder.

TIME VELO

Use this to set how much the Time1 (time) value of the pitch envelope 

changes in response to how hard you play the keys. Set this to a “+” 

value to make the Time1 value longer when you play harder, and set 

this to a “-” value to make the value shorter when you play harder.

TIME KEY FOLLOW

Use this to set how much the Time2–Time4 values (pitch envelope 

time) change according to the keys you play. When you set this to a 

“+” value, playing higher notes makes the time shorter (with the pitch 

envelope time at C4 or middle C as the base value); and when you set 

this to a “-” value, playing higher notes makes the time longer. Larger 

values produce greater change.

[L0] [L1] [L2] 

These set the pitch envelope levels. Use these knobs to determine how 

much the pitch changes at each point in relation to the base pitch. Use 

“+” values for pitches higher than the base pitch, and use “-” values for 

pitches lower than the base pitch.

[T1] [T2] [T3] 

These set the pitch envelope times. Larger values make the time to 

reach the next pitch longer (for example, T2 sets the time it takes to go 

from L1 to reference pitch).

TVF ENV

VELO

Use this to set how much the TVF envelope changes in response to 

how hard you play the keys. Set this to a “+” value to make the TVF 

envelope respond more when you play harder, and set this to a “-” 

value to make it respond less when you play harder.

TIME VELO

Use this to set how much the Time 1 (time) value of the TVF envelope 

changes in response to how hard you play the keys. Set this to a “+” 

value to make the Time 1 value shorter when you play harder, and set 

this to a “-” value to make the value longer when you play harder.

TIME KEY FOLLOW

Use this to set how much the Time2–Time 4 values (TVF envelope time) 

change according to the key you play. When you set this to a “+” value, 

playing higher notes makes the time shorter (with the Filter envelope 

time at C4 or middle C as the base value); and when you set this to a 

“-” value, playing higher notes makes the time longer. Larger values 

produce greater change.

[L1] [L2] [SUSTAIN LEVEL] [L4] 

These set the TVF envelope levels. Use these knobs to determine how 

much the cutoff frequency changes at each point in relation to the 

base cutoff frequency (the CUTOFF FREQ value).

[T1] [T2] [T3] [T4] 

These set the TVF envelope times. Larger values make the time to 

reach the next cutoff frequency longer (for example, T2 sets the time it 

takes to go from L1 to L2).

TVA ENV

VELO

Set this to change the tone volume according to how hard you play 

the keys. Set this to a “+” value to make the tone louder when you play 

harder, and set this to a “-” value to make the tone softer when you 

play harder.

TIME VELO

Use this to set how much the Time 1 (time) value of the TVA envelope 

changes in response to how hard you play the keys. Set this to a “+” 

value to make the Time 1 value shorter when you play harder, and set 

this to a “-” value to make the value longer when you play harder.

TIME KEY FOLLOW

Set this to change the TVA envelope time (Time2–Time4) according to 

the keys you play. When you set this to a “+” value, playing higher notes 

makes the time shorter (with the AMP envelope time at C4 or middle C 

as the base value); and when you set this to a “-” value, playing higher 

notes makes the time longer. Larger values produce greater change.

[L1] [L2] [SUSTAIN LEVEL] 

These set the TVA envelope levels. Use these knobs to determine how 

much the volume changes at each point in relation to the base pitch 

(the tone level value).

[T1] [T2] [T3] [T4] 

These set the TVA envelope times. Larger values make the time to 

reach the next volume level longer (for example, T2 sets the time it 

takes to go from L1 to L2).

LFO1 / LFO2

LFO2 works the same as LFO1.

[SYNC] button

Turn this on to sync the LFO cycle with the tempo.

RATE

When the [SYNC] button is off, the LFO cycle is set 

irrespective of the tempo. The larger the value, the 

shorter the LFO cycle.
When the [SYNC] button is on, the LFO cycle is set to 

a note length.

DELAY

Sets the time it takes before the LFO effect begins 

after you press a key. The larger the value, the longer 

it takes for the LFO effect to start after you play the 

keyboard. The setting above 100 is “REL.” The “REL” 

setting makes the LFO start right after you release 

the key.

FADE

Sets the time-based change of the LFO as it takes 

effect. Set this to “+” to make the LFO amplitude 

gradually ramp up to maximum. Set this to “-” to make 

the LFO amplitude gradually ramp down to zero. No 

time-based change occurs when this is set to “0.” The 

larger the absolute value, the more time required for 

change.

[WAVEFORM] button

These buttons set the LFO waveform.

[OFFSET] button

Moves the center value for the LFO waveform (the 

pitch or cutoff frequency) up or down.

[KEY TRIG] button

Sets whether to synchronize the start of the LFO cycle 

with the timing you use to play the keys (“ON” to 

synchronize, “OFF” to disable).
