Follow these steps to start playing your YAMAHA YPR-50:

1. Turn on the power: Press the STANDBY/ON switch to turn on the power. To turn it off, press the switch again.

2. Adjust the volume: Play the keyboard and move the MASTER VOLUME slider until the sound reaches a comfortable level. Slide the control to the left to decrease volume and to the right to increase it.

3. Play the keyboard: The YAMAHA YPR-50 features a 76-key keyboard (from E0 – G6) with full touch response for dynamic control.

You can power your YAMAHA YPR-50 using either an AC power adaptor or batteries.

Using an AC Power Adaptor:

Connect the optionally available Yamaha PA-3B Power Adaptor to the DC IN 10-12V jack on the rear panel of the YPR-50, and plug the other end into a suitable electrical outlet. Using other adaptors could result in damage. Unplug the AC Power Adaptor when the instrument is not in use or during electrical storms.

Using Batteries:

1. Turn the instrument upside-down and remove the battery compartment lid.

2. Insert six 1.5-volt size “D” (SUM-1, R-20 or equivalent) batteries, ensuring the positive and negative terminals are properly aligned.

3. Replace the lid.

When the batteries run low, the YPR-50 may not function properly. Replace them with a complete set of six new batteries. Do not mix old and new batteries or different types of batteries.

Using Headphones:

For private practice, connect a set of stereo headphones to the rear panel PHONES/OUTPUT jack. The sound from the built-in speaker system is automatically cut off when headphones are plugged in.

Connecting a Keyboard Amplifier or Stereo System:

1. Ensure the YAMAHA YPR-50 and any external devices are turned off.

2. Set the volume of the external devices to the minimum setting to prevent damage.

3. Connect one end of a stereo audio cable to the PHONES/OUTPUT jack on the rear panel of the YPR-50.

4. Connect the other end of the cable to the LINE IN or AUX IN jack(s) of the external amplifier or stereo system.

5. After connecting, gradually raise the volume controls on all devices while playing the instrument to set the desired listening level.

You can use the included footswitch (Yamaha FC-5) or an optional footswitch (Yamaha FC-4) to sustain the sound of the keyboard voice, similar to a damper pedal on an acoustic piano.

1. Make sure the footswitch plug is properly connected to the DAMPER jack on the rear panel before turning on the power.

2. Press and hold down the footswitch as you play the keyboard to sustain the sound.

Important: Do not press the footswitch while turning the power on. Doing so changes the recognized polarity of the footswitch, resulting in reversed operation.

To select one of the five available voices, simply press the desired VOICE button on the control panel. The available voices are:

• GRAND PIANO

• E. PIANO

• HARPSICHORD

• ORGAN

• STRINGS

To listen to all 20 songs in order, press the DEMO button. Playback will start with the first song, “The Entertainer,” followed by all songs from 1 through 20. To stop the demo playback, press the DEMO button again.

During demo playback, you can use the PAUSE button to temporarily stop the song. Press PAUSE again to resume playback.

1. Hold down the SONG [SELECT] button.

2. While holding the button, press the appropriate key on the keyboard (C5 – G6) that corresponds to the desired song, as indicated on the panel.

3. The selected song will start playing as soon as you release the SONG button.

To stop the song, press the SONG [START/STOP] button. If you press the SONG button without selecting a specific song, the currently selected song will play.

The YAMAHA YPR-50 has several “transport” buttons to control song playback:

• START/STOP, SELECT: Press this to start playback of the currently selected song. Press it again to stop playback.

• PAUSE: Press this during playback to pause the song. Press it again to resume playback from the paused point.

• REW (Rewind): Hold this button down to move measure-by-measure in reverse through the song. The song automatically resumes playback from the selected point when the button is released.

• FF (Fast Forward): Hold this button down to fast forward through the song. The song automatically resumes playback from the selected point when the button is released.

Note: The song cannot be heard when holding down the REW button.

The YAMAHA YPR-50 allows you to independently play back the left-hand and right-hand parts of the songs for practice. Press the PART button to switch among three settings, indicated by the Part lamps:

• Both parts on (default): Both parts can be heard.

• Only the left part is on: The accompaniment part plays, letting you practice the melody with your right hand.

• Only the right part is on: The melody part plays, letting you practice the accompaniment with your left hand.

This setting can be changed even during song playback.

The built-in metronome is a convenient tool for practicing.

1. Set the tempo: Use the TEMPO DOWN/UP buttons to adjust the tempo. The range is 40 – 240 beats per minute. To restore the default tempo, press both TEMPO buttons simultaneously.

2. Turn on the Metronome: Press the METRONOME START/STOP button. The Beat lamp will flash in time with the metronome.

3. Turn off the Metronome: Press the METRONOME button again.

You can also use the metronome while a song is playing back; it will automatically match the tempo and time signature of the song.

To set the metronome’s time signature, simultaneously hold down the METRONOME button and press the key on the keyboard that corresponds to the desired time signature. The time signature may change automatically when a Pianist style or song is selected.

The available settings are:

The Pianist feature provides automatic piano accompaniment for your performances.

1. Select a Pianist Style: Simultaneously hold down the PIANIST STYLE button and press the appropriate key (E0 – B1) to select one of the 20 styles. The selected style is now in standby mode. Pressing only the PIANIST STYLE button will set the previously selected style to standby.

2. Start the Accompaniment: The accompaniment starts automatically when you play a key or chord in the left-hand section of the keyboard (E0 – F#2). You can then play the melody with your right hand.

3. Stop the Accompaniment: To stop the style, press the PIANIST STYLE button again. An ending pattern will play before the accompaniment stops completely.

The YAMAHA YPR-50 uses a “Multi Fingering” system, which recognizes both Single Finger and Fingered chord methods in the accompaniment section of the keyboard (E0 – F#2).

Single Finger Chords:

• Major Chord: Press the root note of the chord (e.g., C for C major).

• Minor Chord: Press the root note together with any black key to its left (e.g., C + Bb for C minor).

• Seventh Chord: Press the root note together with any white key to its left (e.g., C + B for C7).

• Minor Seventh Chord: Press the root note together with any white and black keys to its left (e.g., C + B + Bb for Cm7).

Fingered Chords:

You can play all the notes of the chord with conventional voicing and fingering, and the YAMAHA YPR-50 will recognize it. The system can recognize various chord types, including major, minor, seventh, suspended, augmented, and diminished chords. If a chord is inverted (e.g., C-E-G played as G-C-E), it will still be recognized as a C chord.

You can adjust the tempo in two ways:

Adjusting the Tempo Gradually:

Press the TEMPO UP or DOWN buttons. The tempo changes by a small amount with each press. The range is 40-240 beats per minute. To instantly reset to the song’s or style’s preset tempo, simultaneously press both the TEMPO UP and TEMPO DOWN buttons.

Setting the Tempo Value Directly:

To quickly jump to a specific tempo, simultaneously hold down both the TEMPO UP and TEMPO DOWN buttons and press the appropriate key on the keyboard (Eb5 – G6) corresponding to the desired tempo value printed on the panel. The range for this method is 40-200 beats per minute.

The Transpose function changes the key of the main voice, Pianist accompaniment, and songs. This allows you to play in a different key without changing your fingering. The range is +/- 6 semitones (1 octave).

To set the transposition, simultaneously hold down the TRANSPOSE button and press the appropriate key in the TRANSPOSE section of the keyboard (F#2 – F#3). The transpose values are printed above the keys. Normal pitch is “0” at C3. For example, to raise the pitch by one whole step (from C to D), hold TRANSPOSE and press D3.

Note: The Transpose setting cannot be changed during song playback or when the Pianist feature is active.

The Tuning function allows for fine pitch adjustments to match other instruments. The range is +/- 50 cents (approx. +/- 0.5 semitones).

• To Lower the Pitch: Simultaneously hold down the two leftmost keys of the keyboard and press a key in the tuning section (G3 – F#4) to lower the pitch in one-step increments.

• To Raise the Pitch: Simultaneously hold down the three leftmost keys of the keyboard and press a key in the tuning section (G3 – F#4) to raise the pitch in one-step increments.

• To Restore Normal Pitch: Simultaneously hold down all three leftmost keys and press a key in the tuning section to restore the pitch to normal (0).

The METRONOME LEDs indicate the amount of detuning:

Note: The Tuning setting cannot be changed when the Pianist feature is on.

You can set how the instrument’s volume level responds to your playing strength. To change the setting, simultaneously hold down the two highest keys on the keyboard (F#6 and G6) and press the appropriate key in the Touch Sensitivity section:

• FIXED (key: G4): Sets the keyboard to a fixed velocity. The volume remains constant no matter how hard or soft you play.

• SOFT (key: Ab4): Results in limited touch response, producing a narrow dynamic range. This is suited for music that demands consistently high volume, like rock ‘n’ roll.

• MEDIUM (key: A4): This is the default setting. It lets you play the voices over a normal dynamic range (soft to loud).

• HARD (key: Bb4): Designed for playing very soft passages, giving more detailed control in the soft volume range. It is best suited for quiet jazz, new age, and soft ballads.

The YAMAHA YPR-50 has MIDI IN and OUT terminals to interface with other MIDI instruments and devices, such as a sequencer. MIDI (Musical Instrument Digital Interface) is a worldwide standard for connecting and communicating between electronic musical instruments.

A typical use is to record and play back performance data. To do this with a sequencer:

1. Connect the MIDI OUT of the YPR-50 to the MIDI IN of the sequencer.

2. Connect the MIDI IN of the YPR-50 to the MIDI OUT of the sequencer.

This setup allows you to play the YPR-50 keyboard, record the performance data on the sequencer, and then play the data back from the sequencer to have the YPR-50 play the music automatically.

Important MIDI Notes:

• MIDI reception is enabled for channels 1, 2, 3, 4, 5, 6, 7.

• MIDI transmit channels are fixed: Ch. 1 for Keyboard, Ch. 2 for Bass, Ch. 3 for Chord, Ch. 4-7 for Other.

• MIDI data cannot be transmitted during song playback.

• Avoid using MIDI cables longer than 15 meters to prevent errors.
