The YPP-50 contains digital circuitry and may cause interference if placed too close to radio receivers, television sets or similar radio-frequency reception equipment. If such a problem occurs, move the YPP-50 further away from the affected equipment. 10. IMPORTANT!: Check your power supply! Make sure that your local AC mains voltage matches the voltage specified on the name plate on the bottom panel. In some areas a voltage selector may be provided on the rear panel of the main unit. Make sure that the voltage selector is set for the voltage in your area. l Name Plate Location The YPP-50 nameplate is located on the bottom panel.

THE CONTROLS AND CONNECTORS: BASIC OPERATION
POWER Switch Press the POWER switch once to turn the power ON, a second time to turn the power OFF. When the power is initially turned ON, the PIANO voice selector LED will light. MASTER VOLUME Control The MASTER VOLUME control adjusts the volume (level) of sound produced by the Personal Electronic Piano. The MASTER VOLUME control also adjusts headphone volume when a pair of headphones is plugged into the HEADPHONE jack MIDI/TRANSPOSE Button The MIDI/TRANSPOSE button allows access to the Personal Electronic Pianos TRANSPOSE function (to shift the pitch of the entire keyboard up or down) and MIDI functions. For details refer to the TRANSPOSITION and MIDI FUNCTIONS sections on pages 8 and 10, respectively.
METRONOME Button Press the METRONOME button to start the YPP-50s builtin metronome. The metronome will sound at either the initial tempo of 120 beats per minute, or a tempo set using the TEMPO and buttons, described below. The METRONOME button LED will flash on the first beat of each measure. Press the METRONOME button a second time to stop the metronome sound. l Metronome Volume: The volume of the metronome sound can be independently adjusted in five steps (normal volume plus two steps up and two down) by pressing the TEMPO or button while holding down the METRONOME button. The button increases the volume while the button decreases the volume. Normal volume can be restored by holding the METRONOME button and pressing both the TEMPO and buttons simultaneously.
Note: The metronome is also related to operation of the YPP-50 Performance Memory. This relationship will be described in the PERFORMANCE MEMORY section on page 9.
TEMPO and Buttons The TEMPO and buttons are mainly used to adjust the tempo of the YPP-50 metronome. The tempo can be adjusted from 32 to 280 beats per minute in the following steps:
When the power is initially switched ON, the tempo is automatically set to 120. Each brief press on the or button increases or decreases the tempo by one step, respectively. Holding the or button down causes continuous incrementing or decrementing of the tempo value. The initial tempo of 120 can be restored at any time by pressing the TEMPO and buttons simultaneously.
Note: The TEMPO and buttons are also used for transposition and metronome volume control-see METRONOME Button above, and TRANSPOSITION on page 8 for details.
Voice Selectors The YPP-50 has eight voice selectors. Simply press any of the voice selectors to select the corresponding voice. The LED indicator above the voice selector will light to indicate which voice is currently selected. l The Bass Split Mode: The YPP-50 Bass Split Mode allows the BASS voice to be played on all keys to the left of and including the F# 2 key, and any other voice to played on all keys to the right of the F # 2 key. To activate the Bass Split mode and select the right-hand voice, hold down the BASS voice selector and press the voice selector corresponding to the desired right-hand voice, then release both voice selectors. Both the BASS LED and the LED of the selected right-hand voice will light. Please note that the damper pedal does not affect the bass voice in the Bass Split mode. The Bass Split mode can be disengaged and the normal voice mode restored by simply pressing any single voice selector.

Note: The PIANO voice is automatically selected whenever the POWER switch is initially turned ON.
OPTIONAL IN L/R and OUT L/R Jacks These jacks are intended primarily for use with Yamaha EMseries Expander Modules such as the EME-1 Reverb Box, EMT-1 FM Sound Box, EMT-10 AWM Sound Box and EMR-1 Drum Box. In the case of the EME-1 Reverb Box, for example, the OPTIONAL OUT jacks connect to the EME-1 LINE IN jacks, and the EME-1 LINE OUT jacks connect back to the Personal Electronic Piano OPTIONAL IN jacks. This allows application of a range of high-quality digital effects, including reverb and echo, to the Personal Electronic Piano sound. Refer to the EM-series Expander Module device owners manual for connection details. DAMPER Jack The supplied damper pedal (Yamaha FC-5) should be plugged in here. The damper pedal functions in the same way as a damper pedal on an acoustic piano. When the damper pedal is pressed notes played have a long sustain. Releasing the pedal immediately stops (damps) any sustained notes. MIDI IN and OUT Connectors The MIDI IN connector receives MIDI data from anexternal MIDI device (such as the EMQ-1 Memory Box) which can be used to control the Personal Electronic Piano. The MIDI OUT connector transmits MIDI data generated by the Personal Electronic Piano (e.g. note and velocity data produced by playing the Personal Electronic Piano keyboard). More details on MIDI are given in MIDI FUNCTIONS on page 10.
PERFORMANCE MEMORY REC and PLAY Buttons These buttons activate the YPP-50 Performance Memory record and playback functions. Operation of the Performance Memory is described in detail on page 9. DEMO Button Press the DEMO button to hear the YPP-50s pre-programmed demonstration. Further details are given on page 8. HEADPHONE Jack A standard pair of stereo headphones can be plugged in here for private practice or late-night playing. The internal speaker system is automatically shut off when a pair of headphones is plugged into the HEADPHONE jack.

ENJOY THE DEMONSTRATION

To give you an idea of the YPP-50s sophisticated capabilities, it is programmed with a demonstration sequence which plays automatically while demonstrating some of the instruments voices. Short segments of the following pieces are included: l 24 Preludes No. 15 in D flat major. Raindrop Op.28-15 by Chopin (PIANO voice). l The Harmonious Blacksmith by Hndel (HARPSI voice). l Arabesque by Debussy (PIANO voice). l Fugue in G minor by Bach (P.ORGAN voice). 1. Press the POWER switch to turn the instrument ON. The PIANO voice selector LED will light when the power is ON.

Note: Recording can not be activatedif the YPP-60 Multi-Timbre Mode is engaged (see The Multi-Timbre Mode in the MIDI FUNCTIONS section of this manual-page 101.

Recording

1. Set the Record Ready Mode Press the PERFORMANCE MEMORY REC button. This engages the record ready mode: the REC LED will light and the metronome will sound at the currently selected tempo.
2. Set the Tempo Before actually beginning to record, you should select a tempo that will be easy to record at (using the TEMPO and/or buttons). If you dont want to hear the metronome while recording, press the METRONOME button at this stage the metronome sound will stop but the METRONOME LED will continue flashing at the selected tempo. 3. Start Recording Recording will begin automatically as soon as you begin playing. 4. Stop Recording Press the REC button a second time to stop recording. It is also possible to stop recording by pressing the PLAY button. Recording will stop automatically if you exceed the Performance Memory note capacity.
Whenever you record using the Performance Memory, any previously recorded material will be erased. The Performance Memory can be erased deliberately as follows: press the PERFORMANCE MEMORY REC button while holding down the E 0 and F0 keys (the two lowest white keys on the keyboard), release the button and keys, and then press the PERFORMANCE MEMORY REC button one more time to exit the record mode.

Playback

THE PERFORMANCE MEMORY
The YPP-50 Performance Memory functions as a digital recorder that allows you to record and play back anything you play on the keyboard. You can simply enjoy listening to playback of your performance, or play along with it on the keyboard. You can record using any single voice, or using the Bass Split mode for a combination of left-hand bass and right-hand chords or melody lines.
1. Press the PLAY Button Playback of the Performance Memory recording begins as soon as you press the PERFORMANCE MEMORY PLAY button (the PLAY button LED will also light).
The Performance Memory records the following data: notes played, damper pedal operations, voice selection, bass split mode, the initial tempo and tempo changes made during the recording. Up to approximately 1300 notes can be recorded in the Performance Memory. This number varies, however, according to damper-pedal usage and other factors. Material recorded using the Performance Memory will be retained in the YPP-50 memory for approximately one week even the power is left OFF the entire time. To keep the recorded performance in memory for longer periods, make sure that the YPP-50 power is turned ON briefly at least once a week.

This same type of musical information transfer is used for MIDI sequence recording. A sequence recorder such as the Yamaha EMQ-1 Memory Box can be used to record MIDI data received from a Personal Electronic Piano, for example. When the recorded data is played back, the Personal Electronic Piano automatically plays the recorded performance in precise detail.
Control Change Numbers Control Change data representing damper pedal operations is transmitted by the Personal Electronic Piano whenever the pedal is used. If the receiving device is a tone generator or another keyboard, it will respond in the same way as the Personal Electronic Pianos internal tone generator when these controls are used. The Personal Electronic Piano also receives and responds to these as well as some additional control change data described in the MIDI DATA FORMAT section of this manual. See Control Change ON/OFF on page 11 for information on turning control change number reception and transmission ON or OFF.
Note: None of the YPP-50 MIDI functions can be engaged while the built-in metronome is running.
MIDI Transmit & Receive Channel Selection
The MIDI system allows transmission and reception of MIDI data on 16 different channels. Multiple channels have been implemented to allow selective control of certain instruments or devices connected in series. For example, a single MIDI sequence recorder could be used to play two different instruments or tone generators. One of the instruments or tone generators could be set to receive only on channel 1, while the other is set to receive on channel 2. In this situation the first instrument or tone generator will respond only to channel-l information transmitted by the sequence recorder, while the second instrument or tone generator will respond only to channel-2 information. This allows the sequence recorder to play two completely different parts on the receiving instruments or tone generators.
The examples given above really only scratch the surface. MIDI can do much, much more. The YPP-50 offers a number of MIDI functions that allow it to be used in fairly sophisticated MIDI systems.
Note: Always use a high-quality MIDI cable to connect MIDI OUT to MIDI IN terminals. Never use MIDI cables longer than about 15 meters, since cables longer than this can pick up noise which can cause data errors.

MIDI Messages Transmitted & Received by the Personal Electronic Piano ___
The MIDI information (messages) transmitted and received by the YPP-50 Personal Electronic Piano are as follows: Note and Velocity Data This information tells the receiving keyboard or tone generator to play a certain note (specified by the MIDI note number) at a certain dynamic level (specified by the MIDI velocity value). Note and velocity data is transmitted by the Personal Electronic Piano whenever a key is pressed, and the Personal Electronic Pianos internal AWM tone generator will play the corresponding note(s) whenever note and velocity data is received from an external MID1 device.
In any MIDI control setup, the MIDI channels of the transmitting and receiving equipment must be matched for proper data transfer. An OMNI receive mode is also available, which allows reception on all 16 MlDI channels. In the OMNI mode it is not necessary to match the receive channel of the receiving device to the the transmit channel of the transmitting device (except when receiving mode messages).
Setting the Personal Electronic Piano MIDI Channels 1. Press and hold the MIDI/TRANSPOSE button. 2. Press the key on the keyboard corresponding to the desired MIDI transmit or receive channel.* 3. Release the MIDI/TRANSPOSE button.
* Keys C 1 through D#2 on the keyboard are used to set the MIDI transmit channel, and keys C3 through D# 4 are used to turn the OMNI mode OFF and set the MIDI receive channel as shown in the illustration below. The E 4 key sets the OMNI receive mode and basic receive channel 1.
Turning Local Control ON or OFF 1. Hold down the MIDI/TRANSPOSE button. 2. Press the PIANO voice selector. If the PIANO LED is lit when the PIANO voice selector is pressed; you have turned local control OFF. If the PIANO LED is not lit when the PIANO voice selector is pressed, you have turned local control ON. 3. Release the MIDI/TRANSPOSE button.

Program Change ON/OFF

Normally the Personal Electronic Piano will respond to MIDI program change numbers received from an external keyboard or other MIDI device, causing the correspondingly numbered Personal Electronic Piano voice to be selected. The Personal Electronic Piano will normally also send a MIDI program change number whenever one of its voices is selected, causing the correspondingly numbered voice or program to be selected on the external MIDI device if the device is set up to receive and respond to MIDI program change numbers. This function makes it possible to cancel program change number reception and transmission so that voices can be selected on the Personal Electronic Piano without affecting the external MIDI device, and vice versa. 1. Hold down the MIDI/TRANSPOSE button. 2. Press the E.PIANO voice selector. If the E.PIANO LED is lit when the E.PIANO voice selector is pressed, you have turned program change reception/transmission OFF. If the E.PIANO LED is not lit when the E.PIANO voice selector is pressed, you have turned program change reception/transmission ON. 3. Release the MIDI/TRANSPOSE button.

Note: When the power is initially turned ON, MIDI receive is set to the OMNI mode and the transmit channel is set to 1.

The MIDI functions listed above are engaged by holding down the MIDI/TRANSPOSE button and pressing the corresponding voice selector. Full details are given in the following pages.
Control Change ON/OFF Local Control ON/OFF
Local Control refers to the fact that, normally, the Personal Electronic Piano keyboard controls its internal tone generator, allowing the internal voices to be played directly from the keyboard. This situation is Local Control ON since the internal tone generator is controlled locally by its own keyboard. Local control can be turned OFF, however, so that the Personal Electronic Piano keyboard does not play the internal voices, but the appropriate MIDI information is still transmitted via the MIDI OUT connector when notes are played on the keyboard. At the same time, the internal tone generator responds to MIDI information received via the MIDI IN connector. This means that while an external MIDI sequence recorder such as the Yamaha EMQ-1 Memory Box, for example, plays the Personal Electronic Pianos internal voices, an external tone generator such as the EMT-l can be played from the Personal Electronic Piano keyboard. Normally the Personal Electronic Piano will respond to MIDI control change data received from an external MIDI device or keyboard, causing the selected Personal Electronic Piano voice to be affected by pedal and other control settings received from the controlling device. The Personal Electronic Piano also transmits MIDI control change information when either of its pedals are operated. This function makes it possible to cancel control change data reception and transmission if you do not want the Personal Electronic Piano voices to be affected by control change data received from an external device or vice versa. 1. Hold down the MIDI/TRANSPOSE button. 2. Press the HARPSI voice selector. If the HARPSI LED is lit when the HARPSI voice selector is pressed, you have turned control change reception/transmission OFF. If the HARPSI LED is not lit when the HARPSI voice selector is pressed, you have turned control change reception/transmission ON. 3. Release the MIDI/TRANSPOSE button.

The Multi-Timbre Mode

The Multi-Timbre mode is a special mode in which the Personal Electronic Piano voices can be independently controlled on different MIDI channel numbers (1 through 10) by an external MIDI device such as the Yamaha EMQ-1 Memory Box. VOICE CHAN. CHAN. VOICE STRINGS 1 PIANO 7 P.ORGAN E.PIANO 8 BASS 3 HARPSI 4 VIBES 9 PIANO PIANO BRASS The Multi-Timbre mode can be activated as follows: 1. Hold down the MIDI/TRANSPOSE button. 2. Press the VIBES voice selector. If the VIBES LED is lit when the VIBES voice selector is pressed, you have turned the Multi-Timbre mode ON. If the VIBES LED is not lit when the VIBES voice selector is pressed, you have turned the Multi-Timbre mode OFF. 3. Release the MIDI/TRANSPOSE button. Heres an example of how you could use the Multi-Timbre mode to record three different parts on the EMQ-1 Memory Box that will play different voices on the Personal Electronic Piano when played back. 1. Connect the EMQ-1 to the Personal Electronic Piano as shown below.

Activating the Split & Left Local OFF Mode 1. Hold down the MIDI/TRANSPOSE button. 2. Press the STRINGS voice selector. If the STRINGS LED is lit when the STRINGS voice selector is pressed, you have turned the Split & Left Local OFF mode ON. If the STRINGS LED is not tit when the STRINGS voice selector is pressed, you have turned the Split & Left Local OFF mode OFF. 3. Release the MIDI/TRANSPOSE button.
The Split & Right Local Off Mode
In the YPP-50 either the right- or left-hand section of the keyboard can be assigned to control an external keyboard or tone generator. Assigning the left-hand section to external tone generator control was described in the previous section. To assign the right-hand section to external tone generator control while playing the Personal Electronic Piano voices with the left hand, press the BRASS voice selector instead of the STRINGS voice selector when activating the Split mode (See Activating the Split & Left Local OFF Mode in the previous section). All other operations are exactly the same as described in the previous section.
2. Select the first voice and MIDI transmit channel number, then record the first part on the EMQ-1. 3. Activate the Personal Electronic Piano Multi-Timbre mode, then select a new MIDI transmit channel and voice and record the second part on the EMQ-1 using its overdubbing function. 4. While still in the Multi-Timbre mode, select the third MIDI transmit channel and voice and record the third part on the EMQ-1 using its overdubbing function. 5. Still in the Multi-Timbre mode, play back the EMQ-1. The recorded parts will be played back using the individual voices selected during recording, providing a full ensemble sound.
Transmitting the Panel Settings
This function causes all the current Personal Electronic Piano control settings (selected voice, etc) to be transmitted via the MIDI OUT terminal. This is particularly useful if you will be recording performances to a MIDI sequence recorder* which will be used to control the Personal Electronic Piano on playback. By transmitting the Personal Electronic Piano panel settings and recording them on the MIDI sequence recorder prior to the actual performance data, the Personal Electronic Piano will be automatically restored to the same settings when the performance is played back. * The
Yamaha EMQ-1 Memory Box automatically receives and records the Personal Electronic Piano panel settings when a recording is begun, so this function is most useful with MIDI sequence recorders other than the EMQ-1.
The Split & Left Local OFF Mode
In the split mode one section of the Personal Electronic Piano keyboard is used to play a Personal Electronic Piano voice in the normal way, while the remaining section is used to play a second MIDI keyboard or tone generator such as the Yamaha EMT-1 FM Sound Box or EMT-10 AWM Sound Box. In this mode the right-hand section of the keyboard is used to play an internal Personal Electronic Piano voice, while the left-hand section of the keyboard plays the external keyboard or tone generator. Playing the left-hand section of the keyboard produces no sound from the Personal Electronic Piano. The split point, or the key that divides the left- and right-hand sections of the keyboard, is automatically set at F#2. The split mode is useful if, for example, you want to play a piano (Personal Electronic Piano) voice with the right hand while playing a synthesizer bass line or string section with the left hand. When the split mode is activated, notes played on the lefthand section are transmitted via the Personal Electronic Piano MIDI OUT connector on MIDI channel 2. Notes played on the right-hand section are transmitted on the basic channel (i.e. the channel set using the MIDI channel selection function described previously). Damper pedal data is sent via both channels.

1. Hold down the MIDI/TRANSPOSE button. 2. Press the P.ORGAN voice selector. 3. Release the MIDI/TRANSPOSE button.

TROUBLESHOOTING

If you encounter what appears to be a malfunction, please check the following points before assuming that your Personal Electronic Piano is faulty. 1. No Sound When the Power is Turned ON Is the AC plug properly connected to an AC wall outlet? Check the AC connection carefully. Is the MASTER VOLUME control turned up to a reasonable listening level? 2. The Personal Electronic Piano Reproduces Radio or TV Sound This can occur if there is a high-power transmitter in your vicinity. Contact your Yamaha dealer. 3. Intermittent Static Noise This is usually due to turning ON or OFF a household appliance or other electronic equipment which is fed by the same AC mains line as your Personal Electronic Piano. 4. Interference Appears On Radio or TV Sets Located Near the Personal Electronic Piano The Personal Electronic Piano contains digital circuitry which can generate radio-frequency noise. The solution is to move the Personal Electronic Piano further away from the affected equipment, or vice versa. 5. Distorted Sound When the Personal Electronic Piano is Connected to An External Amplifier/Speaker System If the Personal Electronic Piano is connected to a stereo system or instrument amplifier and the sound is distorted, reduce the setting of the Personal Electronic Piano volume control to a level at which the distortion ceases.
