Yamaha Clavinova CLP-154S Owner's Manual

If there is no sound from your Yamaha Clavinova CLP-154S speakers when the power is turned on, first check if the AC plug is properly connected to an AC wall outlet. Also, ensure the MASTER VOLUME control is turned up to a reasonable listening level. Additionally, if headphones are plugged into either of the PHONES jacks, the internal speaker system is automatically shut off.

To adjust the touch sensitivity or keyboard response, hold the MIDI/TRANSPOSE button and press the REVERB button repeatedly until the indicator corresponding to the desired setting lights up. The available settings are:

• HARD: Requires playing keys quite hard for maximum loudness.
• MEDIUM: Produces a standard keyboard response (initial factory default).
• SOFT: Allows maximum loudness with relatively light key pressure.
• FIXED: All notes are produced at the same volume, regardless of key pressure.

To memorize the current touch sensitivity setting, hold the MIDI/TRANSPOSE and REVERB buttons simultaneously, then press the C7 key.

To change the instrument sounds, simply press any of the voice selectors on the control panel. The LED corresponding to the selected voice will light up to indicate which voice is currently active.

To connect the Yamaha Clavinova CLP-154S to a computer for MIDI recording, use the MIDI OUT connector on the Clavinova to transmit MIDI data generated by playing the keyboard. The computer or MIDI recording device would receive this data via its MIDI IN connector. The Clavinova also has a MIDI IN connector to receive MIDI data from external devices and a MIDI THRU connector to re-transmit received MIDI data.

To use the dual voice (layer) 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 dual mode is active. To return to the normal single-voice play mode, press any single voice selector. You can adjust the balance between the two voices using the C2 through C4 keys on the keyboard while pressing the two voice selectors. The C3 key provides equal (50:50) balance.

To transpose on the Yamaha Clavinova CLP-154S, press and hold the [MIDI/TRANSPOSE] button. While holding the button, press a key between F#2 and F#3 on the keyboard corresponding to the desired amount of transposition. Finally, release the [MIDI/TRANSPOSE] button. Pressing the C3 key restores normal keyboard pitch. Keys to the left of C3 transpose the pitch down, while keys to the right of C3 transpose it up, with a maximum shift of six semitones in either direction.

To adjust the reverb effect, press the REVERB button repeatedly until the indicator for the desired reverb type lights up. To adjust the depth of the selected reverb effect, hold the REVERB button and use the C2 through C4 keys on the keyboard. The C3 key sets the normal depth, keys to the left decrease the depth, and keys to the right increase it. To memorize the reverb type and depth settings, hold the REVERB button and press the C7 key.

Yes, the Yamaha Clavinova CLP-154S features a 2-track digital recorder that allows you to record and play back performances directly on the keyboard, with a maximum capacity of approximately 4,200 notes. To record, press the RECORDER [REC] button to engage record ready mode, select the track you want to record on, and then recording will begin automatically as soon as you play a note or press the PLAY button.

The Yamaha Clavinova CLP-154S has three foot pedals with the following functions:

• Soft (Left) Pedal: Reduces the volume and slightly changes the timbre of notes played.
• Sostenuto (Center) Pedal: Sustains notes or chords held when the pedal is pressed, while allowing subsequently played notes to remain unsustained.
• Damper (Right) Pedal: Provides a long sustain for notes played. When no reverb effect is selected, it also produces a special "resonance" effect that simulates the sound of an acoustic piano's strings and soundboard.

Yes, you can connect external speakers to the Yamaha Clavinova CLP-154S using the AUX OUT L/L+R and R jacks. These jacks deliver the output of the Clavinova for connection to an instrument amplifier, mixing console, PA system, or recording equipment. If connecting to a monaural sound system, use only the L/L+R jack.

To perform a factory reset, hold the C7 key while turning the [POWER] switch ON. This action will restore all dual mode, reverb, brilliance (CLP-155), touch sensitivity, and pitch control settings to their original factory preset values and will also erase all recorder data.

The Yamaha Clavinova CLP-154S has two pairs of standard stereo headphone jacks located on the bottom panel. Plugging headphones into either jack automatically shuts off the internal speaker system.

Yes, the Yamaha Clavinova CLP-154S has a built-in metronome function. You can turn it on and off using the METRONOME button. The metronome volume can be adjusted using the TEMPO control while holding the METRONOME button. The time signature can be set by holding the METRONOME button and pressing the appropriate voice selector button.

The Yamaha Clavinova CLP-154S has six voice selectors: PIANO 1, PIANO 2, CLAVINOVA TONE, E. PIANO, HARPSICHORD, and ORGAN.

To properly clean and maintain the surface of your Clavinova:

• Clean the cabinet and keys only with a clean, slightly damp cloth. A neutral cleanser may be used if desired.
• Never use abrasive cleansers, waxes, solvents, or chemical dust cloths, as these can dull or damage the finish.
• Never place any vinyl products on your Clavinova, as contact with vinyl can cause irreversible damage to the finish.

To play the demo songs, press the [DEMO] button to engage the demo mode; the voice selectors will flash in sequence. Then, press one of the flashing voice selectors to start playback of the corresponding demo tune. The demo tunes will play in sequence until stopped, starting with the selected tune. The voice selector indicator will flash during demo playback. You can adjust the volume using the MASTER VOLUME control. To play a different demo tune during playback, simply press the corresponding voice selector. To stop the demo, press the [DEMO] button again.

Yes, the Yamaha Clavinova CLP-154S has a dedicated ORGAN voice selector, allowing you to play organ sounds.
