Yamaha CLP-154S, CLP-155

The Dual Mode

The DUAL mode makes it possible to play two voices simultaneously across the entire range of the key-

board. To activate the DUAL mode simply press two voice selectors at the same time (or press one voice

selector while holding another). The voice indicators of both selected voices will light when the DUAL mode

is active. To return to the normal single-voice play mode, press any single voice selector.

The volume levels of the two voices combined in the DUAL mode are

normally set automatically to produce a pleasing balance (see “Default Set-

tings” below). The balance can be adjusted manually by using the C2

through C4 keys on the keyboard while pressing the two voice selectors

corresponding to the voices to be combined in the DUAL mode.

The C3 key produces equal (50:50) balance between the two voices,

while keys to the left of C3 increase the volume of the left voice in relation

to the right voice, and keys to the right of C3 increase the volume of the

right voice in relation to the left voice. By “left” and “right” voice we refer

to the relative positions of the voice selectors — i.e. in a PIANO 2/

CLAVINOVA TONE combination PIANO 2 is the left voice and

CLAVINOVA TONE is the right voice.

Depending on which voices you combine using the DUAL mode, the

combination may sound better if one of the voices is shifted up an octave.

To shift the right voice, press the C5 key while pressing the two voice se-

lectors corresponding to the voices to be combined in the DUAL mode.

Press C5 again to shift the voice back to its normal range. Use the C1 key

in the same way to shift the left voice.

Default octave settings are provided for all voice combinations, as listed

in the “Default Settings” chart, below.

In a DUAL mode voice combination using STRINGS and any other

voice, it is possible to switch the STRINGS voice to a slow-attack variation

when initially selecting the voices by pressing the [STRINGS] selector

twice while holding the other voice selector. Repeat this operation to return

to the normal STRINGS voice attack.

●Memorizing the Balance,

Strings Type (CLP-155), &

Octave Shift Settings

Press the C7 key while holding any two voice selectors to memorize all

balance, STRINGS voice attack variation (CLP-155), and octave shift settings

made since the power was turned on. The memorized settings will be retained

in memory for about one week after the power is turned off, then the default

settings will be restored. To keep the memorized settings for longer periods,

turn the power on briefly at least once a week.

If these settings are not memorized as described above, they are retained in

memory only until the Clavinova is turned off.
