1 Voice Parameters

1-1 Basic Terms

1-1-1 Definitions

Voice A Voice is a musical instrument sound that is built into an Electronic

Musical Instrument.

There are two Voice Types:

 Normal Voices

 Drum Voices

Normal Voice Normal Voices are mainly pitched musical instrument-type sounds.

You can play over the range of the keyboard at the standard pitch for each

key. Normal Voices consist of one or more Elements (see "Element").

Drum Voice Drum Voices are mainly percussion/drum sounds.

A Drum Voice consists of mainly percussion/drum sounds that are

assigned to individual notes on the keyboard, or a collection of assigned

percussion/drum waves. The Drum Voice is also known as a Drum Kit.

Figure 1: Individual drum sounds, different for each key.

Element An Element is the smallest unit that makes up a Normal Voice.

An Element is created by applying Voice Parameters to sound material. A

single Normal Voice can be created by combining several Elements.

Drum Key A Drum Key is the smallest unit that makes up a Drum Voice.

A Drum Key is assigned to individual notes on the Keyboard. The

percussion/Drum wave is assigned to a Drum Key.

Voice Edit A function that lets you create your own Voices.

Use Voice Edit to adjust or apply Voice Parameters to a Voice.

For Normal Voices:

 Use Common Edit to edit the settings that are common to all

Elements;

 Use Element Edit to edit the settings for each Element separately.

For Drum Voices:

 Use Common Edit to edit the settings that are common to all keys;

 Use Key Edit to edit the settings for each key separately.

GM General MIDI (GM) is a worldwide standard for Voice organization and

MIDI functions of synthesizers and tone generators.

This standard ensures that any song sounds virtually the same on any GM

device of any manufacturer. The GM Voice Bank on this synthesizer is

designed to appropriately play back GM song data. However, the sound

may not be exactly the same as played by the original tone generator.

1-2 Synthesis Parameters

1-2-1 Oscillator

An Oscillator outputs the waveform that determines the basic pitch of an Element and is one

unit of the tone generator block of the Electronic Musical Instrument.

You can:

 Assign the waveform (or basic sound material) to each Element of a Normal Voice or each

key of a Drum Voice;

 Set the note range for the Element (Normal Voice);

 Set the Velocity response (Normal Voice);

 Set the XA (eXpanded Articulation) parameters.

Element Switch Switches a selected Element On or Off.

Elements for which the Element Switch is switched off will not sound.

XA Control Determines the functioning of the Expanded Articulation (XA) feature of an

Element.

The XA feature is sophisticated tone generator system that allows you to

more effectively recreate realistic sound and natural performance

techniques. It also provides other unique modes for random and alternate

sound changes as you play.

For each Element, you can set to:

 Normal: The Element sounds normally each time you play the note.

 Legato: When the Mono/Poly parameter is set to Mono, this Element

will be played in place of the one which is set to "Normal" of the XA

Control parameter when you play the keyboard in legato fashion

(playing the next note of a single-note line or melody before releasing

the previous note).

 Key off sound: The Element will sound each time you release the

note.

 Wave cycle (for multiple Elements): Each Element sounds

alternately according to its numerical order. In other words, playing

the first note will sound Element 1, the second note Element 2, and

so on.

 Wave random (for multiple Elements): Each Element will sound

randomly each time you play the note.

 AF 1 on: When the ASSIGNABLE FUNCTION [1] button is turned

On, the Element will sound.

 AF 2 on: When the ASSIGNABLE FUNCTION [2] button is turned

On, the Element will sound.

 All AF off: When both the ASSIGNABLE FUNCTION [1] and [2]

buttons are turned Off, the Element will sound.

To create the desired sound, assign the same Element Group to all

Elements that have the same XA features. See "Element Group".

Element Group Determines the group for XA Control.

The Elements of a group can be called up in sequential order or in random

order. All Elements that have the same type of XA features must have the

same group number.

This setting does not apply when the XA Control parameters of all

Elements are set to Normal.

Voice Parameters

6

Waveform Bank Specifies the Waveform Bank of an Element or Drum Key (Drum Voice).

 Preset

 User: This lets you create User Waveforms based on samples that

are recorded in the Sampling mode.

Waveform Category and

Number

Specifies the waveform of an Element (Normal Voice) or Drum Key (Drum

Voice).

The waveform is specified as a combination of a Waveform Category and

a Waveform Number.

Assign Mode (for Drum

Voices)

Enables or disables double playback of the same note.

 Single: Double or repeated playback of the same note is not possible.

The first note will be stopped, then the next note will be sounded.

 Multi: All notes are sounded simultaneously. This allows playback of

the same note when it is played multiple times in succession

(especially for tambourine and cymbal sounds that you would want to

ring out to their full decay).

In general, you can use the setting Multi. Keep in mind that the Multi

setting consumes overall polyphony and that sounds may be cut off.

Receive Note Off (for

Drum Voices)

Determines whether a Drum Key responds to the MIDI Note Off message

or not.

 On: Stops the sound when you release the key (Drum Key). For

sustained, non-fading drum sounds.

 Off: Continues the (fading) sound when you release the key (Drum

Key).

Alternate Group (for

Drum Voices)

Prevents playback of unnatural combinations of Drum Keys.

You should assign Drum Keys that cannot be played simultaneously on a

real Drum Kit (like open and closed hi-hats) to the same Alternate Group.

Select Off for Drum Keys that can be played simultaneously.

Key On Delay Defines the time delay between when a key is pressed and the

corresponding sound is actually played.

The higher the value, the longer the delay time.

Delay Tempo Sync Determines if the Key On Delay is synchronized to the tempo of the

Arpeggio or sequencer (Song or Pattern).

Delay Tempo Determines the timing of the Key On Delay when the Delay Tempo Sync

is set to On.

Velocity Cross Fade Determines how gradually the volume of an Element decreases in

proportion to the distance of Velocity changes outside the Velocity Limit

setting.

 The higher the value, the more gradual the volume decreases.

 0: No sound outside the Velocity Limit (see "Velocity Limit") is

produced.

Use this parameter to create natural-sounding Velocity cross fades, in

which different Elements change gradually depending on the strength at

which you play the keyboard.

Voice Parameters

7

Velocity Limit Determines the minimum and maximum Velocity values in which an

Element responds.

Each Element will only sound for notes played between its specified

Velocity Limits.

For example, this lets you have one Element sound when you play softly

and have a different one sound when you play strongly.

If you first specify the maximum value and then the minimum value, for

example "93 to 34," then the Velocity range covers both "1 to 34" and

"93to127."

Note Limit Determines the lowest and highest notes of the keyboard range for an

Element.

The selected Element will sound only when you play notes within this

range.

If you first specify the highest note and then the lowest note, for example

"C5 to C4", then the note range covers both "C-2 to C4" and "C5 to G8."

Voice Parameters

8

1-2-2 Pitch

The processing unit that controls the pitch of the wave output from the Oscillator on the tone

generator block of the Electronic Musical Instrument.

This unit controls the pitch of the sound (wave) output from the Oscillator. In the case of a

Normal Voice, you can detune separate Elements, apply Pitch Scaling and so on. Also, by

setting the Pitch Envelope Generator (Pitch EG), you can control how the pitch changes over

time.

Coarse Tuning Determines the pitch of each Element (Normal Voice) or each Drum Key

(Drum Voice) in semitones.

Fine Tuning Determines the pitch of each Element or each Drum Key in cents.

The term "cent" refers to one hundredth of a semitone (i.e., 100 cents = 1

semitone).

Pitch Velocity Sensitivity Determines how the pitch of the Element or Drum Key responds to

Velocity.

 Positive values: The pitch rises more, the harder you play the

keyboard.

 Negative values: The pitch falls more, the harder you play the

keyboard.

 0: No change in pitch.

Fine Scaling Sensitivity Determines the degree to which the notes (specifically, their position or

Octave Range) affect the pitch in Fine Tuning of the selected Element,

assuming C3 as the basic pitch.

 Positive values: The pitch of lower notes drops and that of higher

notes rises.

 Negative values: The pitch of lower notes rises and that of higher

notes drops.

Random This lets you randomly vary the pitch of the Element for each note you play.

 The higher the value, the greater the pitch variation.

 0: No pitch change.

Pitch Key Follow

Sensitivity

Determines the sensitivity of the Key Follow effect (the pitch interval of

adjacent notes), assuming the pitch of the Center Key as standard.

 +100% (the normal setting): Adjacent notes are pitched one semitone

apart.

 0%: All notes are the same pitch specified as the Center Key.

 Negative values: The settings are reversed.

This parameter is useful for creating alternate tunings, or for use with

sounds that do not need to be spaced in semitones, such as pitched drum

sounds in a Normal Voice.

Voice Parameters

1-2-3 Pitch EG (Pitch Envelope Generator)

This lets you control the transition in pitch from the moment the sound starts to the moment the

sound stops. You can create the Pitch EG by setting parameters as illustrated below. When

you press a key on the keyboard, the pitch of the Voice will change according to these Pitch

EG settings.

This is useful for creating automatic changes in pitch, which is effective for Synth Brass

sounds.

Hold Time Determines the time between the moment you press a key on the

keyboard and the moment the envelope starts to rise.

Attack Time Determines the speed of attack from the initial pitch (Hold Level) to the

normal pitch of the Voice after the hold time has elapsed.

Decay 1 Time Determines how fast the envelope falls from the normal pitch (Attack

Level) of the Voice to the pitch specified as the Decay 1 Level.

Decay 2 Time Determines how fast the envelope falls from the pitch specified as the

Decay 1 Level to the pitch specified as the Decay 2 Level.

Release Time Determines how fast the envelope falls from the pitch specified as the

Decay 2 Level to the pitch specified as the Release Level when the note is

released.

Hold Level Determines the initial pitch at the moment the key is pressed.

Attack Level Determines the normal pitch of the pressed key.

Decay 1 Level Determines the level which the pitch of sound reaches from the Attack

Level after the Decay 1 time elapses.

Decay 2 Level Determines the sustain-level pitch which will be maintained while a note is

held.

Release Level Determines the final pitch reached after the note is released.

EG Depth Determines the range over which the pitch envelope changes.

 0: The pitch does not change.

 The farther from 0 the value is, the larger the pitch range.

 Negative values: The pitch change is reversed.

1-2-4 Filter

A filter is a circuit or processor that modifies tone by blocking or passing a specific frequency

range of the sound.

Filters work by allowing portions of the signal lower or higher than a given frequency to pass,

and cutting the remainder of the signal. This given frequency is referred to as the Cutoff

Frequency. You can produce a relatively brighter or darker sound depending on how you set

the Cutoff Frequency.

By adjusting the Resonance (which boosts the level of the signal in the area of the Cutoff

Frequency), you can produce a distinctive "peaky" tone, making the sound brighter and harder.

On the tone generator block of the Electronic Musical Instrument, the sound signal output from

the Pitch unit is processed by the Filter unit.

Cutoff Frequency Determines the Cutoff Frequency for the Filter, or the central frequency

around which the Filter is applied.

The tonal characteristics of the Voice and function of the Cutoff Frequency

differ depending on which Filter Type is selected (see Chapter 1-2-5 Filter

Type).

Voice Parameters

Cutoff Velocity

Sensitivity

Determines how the Cutoff Frequency responds to Velocity, or the strength

with which you play notes.

 Positive values: The Cutoff Frequency rises the stronger you play the

keyboard.

 Negative values: The Cutoff Frequency rises the softer you play the

keyboard.

 0: The Cutoff Frequency does not change, regardless of the Velocity.

Resonance Resonance is used to set the amount of Resonance (harmonic emphasis)

applied to the signal at the Cutoff Frequency.

This parameter can boost the level of the signal in the area of the Cutoff

Frequency. By emphasizing the overtones in this area, this can produce a

distinctive "peaky" tone, making the sound brighter and harder.

This can be used in combination with the Cutoff Frequency parameter to

add further character to the sound.

This parameter is available when an LPF, HPF, BPF (excluding the

BPFw), or BEF is selected as a Filter Type.

Width The Width parameter is used to adjust the width of the band of signal

frequencies passed by the filter with the BPFw.

This parameter is available when a BPFw is selected as a Filter Type.

Resonance Velocity

Sensitivity

Determines the degree to which Resonance responds to Velocity, or the

strength with which you play notes.

 Positive values: The higher the Velocity, the greater the Resonance.

 Negative values: The lower the Velocity, the greater the Resonance.

 0: No change of the Resonance value.

Gain Determines the Gain of the signal sent to the filter.

The lower the value, the lower the Gain. The tonal characteristics

generated by the filter differ depending on the value set here.

Cutoff Key Follow

Sensitivity

Determines the degree to which the notes (specifically, their position or

Octave Range) affect the Cutoff Frequency of the selected Element,

assuming C3 as the basic pitch.

 Positive values: The Cutoff Frequency drops for lower notes and rises

for higher notes.

 Negative values: The Cutoff Frequency rises for lower notes and

drops for higher notes.

Distance Determines the Distance between the two Cutoff Frequencies of the Dual

Filter Types (which consist of two identical filters in parallel), and of the

LPF12+BPF6 type.

When any other Filter Type is selected, this parameter is not available.

HPF Cutoff

Frequency

Determines the central frequency for the Key Follow parameter of the HPF.

This parameter is only available for Filter Types LPF12+HPF12 and

LPF6+HPF6.

HPF Cutoff Key

Follow Sensitivity

Determines the degree to which the notes (specifically, their position or

Octave Range) affect the Cutoff Frequency of the HPF.

 Positive values: The Cutoff Frequency drops for lower notes and rises

for higher notes.

 Negative values: The Cutoff Frequency rises for lower notes and

drops for higher notes.

This parameter is only available for Filter Types LPF12+HPF12 and

LPF6+HPF6.

1-2-5 Filter Type

LPF (Low-Pass

Filter)

This is a Filter Type that only passes signals below the Cutoff Frequency.

The sound can be brightened by raising the Cutoff Frequency of the filter.

On the other hand, the sound can be darkened by lowering the Cutoff

Frequency of the filter. You can produce a distinctive "peaky" sound by

raising the Resonance to boost the signal level in the area of the Cutoff

Frequency.

This Filter Type is most popular and useful for producing classic

synthesizer sounds.

This filter has a smoother cutoff slope than the LPF18 type.

HPF (High-Pass

Filter)

A Filter Type that only passes signals above the Cutoff Frequency.

You can use the Resonance parameter to add further character to the

sound.
