This unit lets you use the top panel harmonic bars to modify the

character of the synthesizer sound.

MEMO

• If you’re playing two sounds (split or dual) (p. 12), the settings

will determine which sound is affected.

• If one of the sounds is an organ sound

The bars will operate as harmonic bars for the organ sound.

The synthesizer sound will not change.

• If one of the sounds is a piano sound

The piano sound cannot be changed. The effect will apply

only to the synthesizer sound.

• If two synthesizer sounds are combined

The bars will affect both synthesizer sounds.

• The effect can also be applied when playing a single piano sound.
• For some acoustic sounds (

&

PDF), DECAY, CUTOFF, and

RESONANCE will have no effect.

Changing the Volume Envelope

(ATTACK, DECAY, RELEASE)

The shape that describes how an instrument’s volume changes

over time from the beginning to the end of the note is called the

“envelope.”
On a keyboard instrument, this specifies the way in which the

volume changes from when you press a key until you release the key.

Parameter

Explanation

ATTACK

Time from when you press the key until the full

volume is reached

DECAY

Time over which the volume reaches the SUSTAIN

level following the attack

SUSTAIN

Volume at which the sound is sustained while you

continue holding the key

RELEASE

Time over which the sound decays to silence after

you release the key

On this unit you can use the three left-most harmonic bars to adjust

the ATTACK, DECAY, and RELEASE times of the currently selected

sound.

1.

Select a sound from the synthesizer section (p . 10) .

2.

Move the bars to adjust the values of the corresponding

parameters .

Bar

Value

Explanation

[ATTACK] bar

-64–63

Lowering the bar will shorten the attack

time; raising the bar will lengthen the

time.

[DECAY] bar

-64–63

Lowering the bar will shorten the time

over which the level falls to the SUSTAIN

level; raising the bar will lengthen the

time.

[RELEASE] bar

-64–63

Lowering the bar will shorten the time

over which the sound disappears; raising

the bar will lengthen the time.

When you operate a bar, the current value is shown in the screen.

MEMO

• While the value of a parameter is displayed, you can turn the

[VALUE] dial to adjust the value.

• The value of each parameter is shown as an offset relative to the

default value originally specified for each sound. At a value of “0”

(the bar near the center “4” position), that parameter will be in its

original state.

• If you press the [TRANSPOSE] button while the adjustment

screen is shown, the adjustment screen will be held. Press the

[EXIT] button to return to the previous screen.

Adjusting the Tonal Character (CUTOFF,

RESONANCE)

The filter determines the tonal character of the sound.
You can use the filter to cut or boost different frequency regions of

the sound, thus modifying its character.

Parameter

Explanation

CUTOFF

Frequency at which the filter takes effect (cutoff

frequency)

RESONANCE

Amount by which the region near the filter’s cutoff

frequency is emphasized

On this unit you can use the two right-most harmonic bars to adjust

the cutoff and resonance of the currently selected sound.

1.

Select a sound from the synthesizer section (p . 10) .

2.

Move the bars to adjust the values of the corresponding

parameters .

Bar

Value

Explanation

[CUTOFF] bar

-64–63

Specifies the cutoff frequency. Lowering

the bar will make the sound darker (more

mellow); raising the bar will make the

sound brighter.

[RESONANCE]

bar

-64–63

Boosts the sound in the region of the

cutoff frequency, producing a distinctive

tonal character. Lowering the bar will

weaken this character, and raising the bar

will strengthen it.

When you operate a bar, the current value is shown in the screen.

* Some settings may produce noise or high-volume sound. Be

careful of the volume of the connected mixer or amp.
