Voice Mode

The Voice mode features 100 authentic Voices.

Many of these Voices have special preset

characteristics or embellishments. The Voices are

divided into various categories depending on their

characteristics or the effects used.

Dual Voices (#41 - #56) feature two Voices mixed

together in a layer for rich ensemble sounds. Split

Voices (#57 - #67) also have two Voices, but rather

than being layered, each is played from a different

range of the keyboard. Sustain Voices (#68 - #72)

extend the sound by adding a natural, slow release.

Harmony Voices (#73 - #85) have an additional one-,

two- or three-note harmony added to the original

monophonic Voice. Finally, Echo Voices (#86 - #00)

have an echo effect that adds delayed repeats to the

original Voice.

Included in the Voices are special PERCUSSION

Voices (#40 and #00) that lets you play various drum

and percussion sounds from the keyboard. (Refer to

the Percussion Assign List page 13.)

Selecting a Voice

Press the VOICE button to select the Voice mode.

Use the Numeric Keypad to select the desired Voice

number.

Each Voice is automatically called up with the most

suitable octave range setting. Thus, playin middle C

with one Voice may sound higher or lower than

another Voice at the same key.

Play the newly selected Voice. To change to another

Voice, repeat step 2 above.

You can also play rhythm Styles in the Voice mode by

simply pressing the START/STOP button. The Style

last selected from the Style mode will be played.

About the Harmony Voices

Since Harmony Voices are designed to automatically

play two or more notes with the notes you play on the

keyboard, only one note can be played on the

keyboard at a time. If several notes are played

together, only the last note or highest note played will

be heard.

The type of harmony used depends on the Voice that

is selected. When a Style or Song/Jam Track is not

being played back, the basic key for the harmony is

always C. When a Style is played or the Stopped

Accompaniment function is active, the harmony

changes according to the chord played with the left

hand. When a Song is played back, the harmony

changes according to the chord progression of the

Song or Jam Track.

NOTE

The PortaTone is polyphonic up to a maximum of 12 notes.

(Depending on the Voice selected, fewer notes may be available.)

This includes not only the Voices played from the keyboard, but

also the notes in a Style pattern, and so on. Thus, if you play too

many notes at one time, some may not sound and/or others may

be cancelled.
