Frequently Asked Questions - P-45 YAMAHA

How to disable auto power off?
Hold down the lowest key (A-1) and press the [O] (Standby/On) switch to turn the instrument back on. The indicator blinks three times to confirm deactivation.
My pedal produces the opposite effect (sound cuts when I press it). What should I do?
This happens if the pedal is pressed when turning on the power. Turn the instrument off, then turn it back on without pressing the pedal.
Can I connect this instrument to an iPad or iPhone?
Yes, via the USB TO HOST port with an appropriate USB cable (type AB). Enable Airplane Mode on your iOS device to avoid interference.
How to transpose the keyboard?
Hold down the [GRAND PIANO/FUNCTION] key and press F6 (lower by a semitone) or G6 (raise); F#6 returns to original pitch. Range of -6 to +6 semitones.
How to layer two voices (Dual mode)?
Hold down [GRAND PIANO/FUNCTION] and press two voice keys simultaneously (C0 to A0). The first key selects voice 1, the second voice 2.
How to use Duo mode for two players?
Hold down [GRAND PIANO/FUNCTION] and press D3. The keyboard is divided into two zones with the split point at E3. Each zone is independent for two musicians.
How to adjust the metronome?

How to lower the pitch of the Yamaha P-45?
Frequently Asked Questions - 17 j
Response Notice-Facile

The Yamaha P-45 offers two ways to lower the pitch:

Transposition by semitone

To lower the keyboard pitch by semitones (up to -6 semitones):

  • Press and hold the [GRAND PIANO/FUNCTION] key (the lowest key on the keyboard)
  • Press the F6 key

You can repeat this operation several times to reach the desired pitch. To return to the original pitch, hold [GRAND PIANO/FUNCTION] and press F#6.

This function is very useful for accompanying a singer or playing in a different key without changing your fingering.

Fine tuning

For a finer adjustment of the frequency (approximately 0.2 Hz per increment):

  • Hold [GRAND PIANO/FUNCTION] and press G#6 to decrease
  • Hold [GRAND PIANO/FUNCTION] and press B6 to return to A3 = 440 Hz (the standard pitch)

This function allows for precise tuning of the piano with other instruments or external audio sources.

Why do I have to press very hard on the keys of the Yamaha P-45 digital piano to get a sound?
Frequently Asked Questions - 11/03/2026
Response Notice-Facile

If you have to press very hard on the keys of your Yamaha P-45 digital piano to get a sound, it is most likely related to the touch sensitivity setting. The P-45 has four different modes that control the keyboard's response to your playing strength. If the Hard mode is activated, you will indeed need to press very hard on the keys to produce a sustained sound with significant dynamic variations.

To adjust the touch sensitivity setting of the Yamaha P-45, hold down the [GRAND PIANO/FUNCTION] key and simultaneously press one of the keys between A2 and C3. Here are the four available modes:

  • A2 (Fixed): The volume remains constant, regardless of the playing strength. The keyboard does not respond to dynamics.
  • A#2 (Soft): The volume changes slightly in response to your playing strength. This mode is suitable if you find the touch too hard.
  • B2 (Medium): This is the default setting, offering a standard response of an acoustic piano with a balance between dynamics and ease of play.
  • C3 (Hard): The volume changes significantly and requires more playing strength. Select this mode if you are currently playing with a lot of pressure and cannot produce the desired sounds.

If the problem persists after trying the Soft or Medium mode, check that your piano does not have a hardware issue. The Yamaha P-45 is equipped with a Graded Hammer Standard (GHS) keyboard with 88 weighted keys, which means it naturally offers some resistance to replicate the touch of an acoustic piano. This resistance is normal and is part of the P-45's design.

In case of persistent mechanical malfunction (stuck keys, faulty velocity sensors, or debris accumulation under the keys), gently clean your keyboard with a soft, dry cloth, and then have the device inspected by a qualified Yamaha technician. Do not attempt to open the piano or modify its internal components yourself.

Why do the keys on the right side of my Yamaha P-45 digital piano not produce the correct sound?
Frequently Asked Questions - 11/03/2026
Response Notice-Facile

Several factors may explain a weak or absent sound on the keys to the right of your Yamaha P-45. Start by checking your setup:

Check the Duo mode. In Duo mode, the keyboard is automatically split at the E3 key: the keys on the left play one sound and those on the right play another. If this mode is accidentally activated, the right sound may be set too low or on an inappropriate quality. To disable it, press and hold the [GRAND PIANO/FUNCTION] key, then press D3. This will restore the full keyboard with a single sound.

Adjust the MASTER VOLUME slider. Make sure that the [MASTER VOLUME] slider located on the front panel is high enough. It controls the overall volume of the piano. A level that is too low will affect all keys. In Dual mode (layering two sounds), you can also adjust the balance between the left and right sounds: press [GRAND PIANO/FUNCTION] + B5 to decrease, C6 to balance, or C#6 to increase.

Check the connections. A headphone plugged into the [PHONES] jack automatically cuts off the built-in speakers. Make sure no plug is connected to this jack. Similarly, if you are using headphones or an external amplifier, first test with the built-in speakers to isolate the problem.

Consider the polyphony limit. The P-45 has a polyphony of 64 notes. With complex pieces or reverb activated, the oldest notes may be cut off if you exceed 64 simultaneous notes. This is a normal limitation of this instrument.

Check the touch sensitivity. In Fixed mode, all keys produce the same volume regardless of your touch. In Hard mode, you need to strike very hard to get a sustained sound. Press and hold the [GRAND PIANO/FUNCTION] key, then press a key between A2 and C3 to adjust this setting (successive keys allow you to choose Fixed, Soft, Medium, or Hard).

Reset the instrument. To return to the default settings, press and hold the C7 key (the farthest right), then turn the instrument on. The indicator blinks during initialization. This action resets the saved data (metronome volume, touch sensitivity, fine tuning, etc.) without loss of function.

If after these steps the keys on the right still do not sound correctly, it is likely that an internal hardware defect is present (key sensors, electronic circuits). In this case, contact an authorized Yamaha dealer or customer service for a professional diagnosis and repair.

How to disable the default pedal function on the Yamaha P-45 digital piano?
Frequently Asked Questions - 03/02/2026
Response Notice-Facile

To disable the default pedal function on your Yamaha P-45 digital piano, follow this simple procedure:

  1. Turn off the piano to start the setup safely.
  2. Press and hold the C1 key (the first white key on the far left) while turning on the piano.
  3. Release the C1 key once the piano is powered on.

This action disables the default pedal function. To reactivate this function, simply repeat the same steps.

This method allows you to modify the behavior of the built-in sustain pedal, which can be useful depending on your playing style or preferences.

How to record your performance on the YAMAHA P-45 digital piano?
Frequently Asked Questions - 03/12/2025
Response Notice-Facile

The YAMAHA P-45 digital piano does not have a built-in recording function. To record your playing, you need to use a computer or an external device with recording software. Here’s how to proceed:

1. Connecting the piano to a computer

  • Use a USB cable to connect the P-45 to your computer.
  • Install the necessary drivers available on the official YAMAHA website if your computer does not automatically recognize the piano.

2. Setting up the recording software

  • Open a MIDI-compatible software, such as GarageBand, Ableton Live, FL Studio, or any other audio/MIDI recording software.
  • In the software settings, select the YAMAHA P-45 as the MIDI input source.
  • Create a new MIDI track to record your performance.

3. Recording the performance

  • Press the record button in the software.
  • Play on your piano; the software will capture the played MIDI notes.
  • Once finished, stop the recording in the software.

4. Saving and exporting

  • Save your project in the software to keep your performance.
  • You can also export your recording in audio format (MP3, WAV, etc.) depending on the options provided by the software.

If you want to record the sound directly (audio) rather than the MIDI notes, you can connect the audio output of the P-45 to an audio interface connected to your computer or to an external recorder.
