NOTE: Although the YPP-50 keyboard stand can be assembled by a single person, the job is much easier with two people.
Open the box and remove all the parts. On opening the box you should find the parts shown in the illustration. Check to make sure that all the required parts, are provided. Invert the main unit (A). When main unit (A) is removed from the box, place it upsidedown on a soft, non-abrasive surface such as a clean rug or blanket to prevent scratches to the finish. This inverted position makes it easier to attach the assembled keyboard stand later on. Attach the side panels (D) to the front (B) and rear (C) panels. Begin by installing the joint connectors in the front (B) and rear (C) panels as shown in the illustration. The front and rear panels (the rear panel is the wider one) are attached between the side panels (D) using two long bolts at each end. The sides of the side panels (D) with the recesses at the top face inwards; the direction in which the feet extend from the side panels is the front (the direction the keyboard faces). The metal brackets on the front (B) and rear (C) panels face upwards and inwards. Attach the first panel loosely so that the second panel slides into position easily, then attach the second panel and finally tighten all eight bolts. When the assembly is complete and the bolts are securely tightened, snap the eight plastic bolt covers into place over the bolt heads.
When installing the joint connectors in the holes in the panels, make sure that the arrows printed on their upper surface face in the direction shown in the illustration.
Attach the stand assembly to the main unit (A). Turn the assembled stand upside down and place it on top of the main unit (which should also be upside-down) with the feet extending toward the keyboard side of the main unit. The tops of the side panels fit into the recessed areas at the ends of the main unit. Align the holes in the front and rear panel brackets with the holes in the bottom of the main unit, and firmly screw in the six short bolts through the brackets. Finally, turn the entire assembly rightside-up and stand it on its feet.
* Check to make sure that all screws have been securely tightened.
Plug in the damper pedal (E) Plug the supplied FC5 damper pedal cable into the DAMPER jack on the rear panel of the main unit, and place the pedal in a convenient position on the floor below the keyboard. Install the music stand (F) Insert the bottom (flat) edge of the music stand (F) into the slot on the top of the main unit (A) so that the music stand leans backwards away from the keyboard.
TAKING CARE OF YOUR PERSONAL ELECTRONIC PIANO
Your Personal Electronic Piano is a fine musical instrument, and deserves the most careful treatment. Observe the following points and your Personal Electronic Piano will sound and look great for many years. 1. Never open the case and touch or tamper with the internal circuitry. 2. Always turn the POWER switch OFF after use, and cover the keyboard with the supplied cover. 3. Clean the cabinet and keys of your Personal Electronic Piano 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 since these can dull or damage the finish. 4. Never place any vinyl products on your Personal Electronic Piano. Contact with vinyl can cause irreversible damage to the finish. 5. Install your Personal Electronic Piano in a place that is away from direct sunlight, excessive humidity or heat. 6. Never apply excessive force to the controls, connectors or other parts of your Personal Electronic Piano, and avoid scratching or bumping it with hard objects. 7. Do not leave heavy objects on the keyboard for an extended length of time. 8. Never spill water, beverages or other liquids on the keyboard or any other part of the Personal Electronic Piano. 9. 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.

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.

3. The demonstration music will begin playing as soon as you press the DEMO button. The demonstration will play continuously, providing samples of different voices, until the DEMO button is pressed a second time.

TRANSPOSITION

The Personal Electronic Pianos TRANSPOSE function makes it possible to shift the pitch of the entire keyboard up or down in semitone intervals up to a maximum of six semitones. Transposing the pitch of the Personal Electronic Piano keyboard makes it easier to play in difficult key signatures, and you can simply match the pitch of the keyboard to the range of a singer or other instrumentalist. The MIDI/TRANSPOSE button and TEMPO and buttons are used for transposition. 1. Press and hold the MIDI/TRANSPOSE button. 2. Press the TEMPO or button as many times as necessary to produce the desired degree of transposition. Each time the TEMPO o r button is pressed the pitch of the keyboard is transposed by one semitone in the specified direction (i.e. up or down). Pitch can be transposed up or down by a maximum of six semitones.* 3. Release the MIDI/TRANSPOSE button.
A different voice or tempo can be selected at any time while the demonstration is playing (refer to the appropriate sections of this manual for instructions). Voice changes, however, will only remain in effect until the next automatic voice change.
PLAYING THE PERSONAL ELECTRONIC PIANO
After making sure that the Personal Electronic Pianos AC plug is properly inserted into a convenient AC wall outlet: 1. Press the POWER switch located to the left of the keyboard to turn the power ON. When the power is turned ON, the PIANO voice selector LED will light (the PIANO voice is automatically selected whenever the power is turned ON).
* Pressing both the TEMPO and buttons simultaneously while the MIDI/TRANSPOSE button is held produces normal keyboard pitch.

PITCH CONTROL

Pitch control makes it possible to tune the Personal Electronic Piano over a 50-cent range in approximately 3-cent intervals. A hundred cents equals one semitone, so the tuning range provided allows fine tuning of overall pitch over a range of approximately a semitone. Pitch control is useful for tuning the Personal Electronic Piano to match other instruments or recorded music. Tuning Up 1. To tune up (raise pitch), hold the E0 and F0 keys simultaneously. 2. Press any key between C3 and B3. Each time a key in this range is pressed the pitch is increased by approximately 3 cents, up to a maximum of 50 cents above standard pitch. 3. Release the E0 and F0 keys. Tuning Down I. To tune down (lower pitch), hold the E0 and F #0 keys simultaneously. 2. Press any key between C3 and B3. Each time a key in this range is pressed the pitch is decreased by approximately 3 cents, up to a maximum of 50 cents below standard pitch. 3. Release the E0 and F# 0 keys. To Restore Standard Pitch* 1. To restore standard pitch (A3 = 440 Hz), hold the E 0, F0 and F# 0 Tkeys simultaneously. 2. Press any key between C3 and B3. 3. Release the E0, F0 and F# 0 keys.

* Standard pitch (A 3 = 440 Hz) is automatically set whenever the POWER switch is initially turned 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.
2. Play Along if You Like Play along on the YPP-50 keyboard if you like. Please note, however, that the YPP-50s eight-note polyphony limitation still applies. In other words, the total number of notes being played back by the Performance Memory and those played on the keyboard cannot exceed eight at any instant. 3. Stop Playback Playback will stop automatically when the end of the recording is reached. You can also stop playback at any time by pressing the PLAY or REC button. Playback will also stop if the DEMO button is pressed or if a MIDI STOP message is received via the MIDI IN connector.

MIDI FUNCTIONS

A Brief Introduction to MIDI
MIDI, the Musical Instrument Digital Interface, is a worldstandard communication interface that allows MIDI-compatible musical instruments and equipment to share musical information and control one another. This makes it possible to create systems of MIDI instruments and equipment that offer far greater versatility and control than is available with isolated instruments. For example, most MIDI keyboards (including the Personal Electronic Piano, of course) transmit note and velocity (touch response) information via the MIDI OUT connector whenever a note is played on the keyboard. If the MIDI OUT connector is connected to the MIDI IN connector of a second keyboard (synthesizer, etc.) or a tone generator such as the Yamaha EMT-1 FM Sound Box (essentially a synthesizer with no keyboard), the second keyboard or tone generator will respond precisely to notes played on the original transmitting keyboard. The result is that you can effectively play two instruments at once, providing thick multi-instrument sounds.
Program Change Numbers The YPP-50 transmits a MIDI program number between 0 and 14 when one of its voice selectors is pressed. This normally causes the correspondingly numbered voice or program to be selected on a receiving MIDI device. The Personal Electronic Piano will respond in the same way, automatically selecting the appropriate voice when a MIDI program change number is received. See Program Change ON/OFF on page 11 for information on turning program change number reception and transmission ON or OFF. NO. VOICE PIANO E.PIANO HARPSI VIBES BRASS STRINGS P.ORGAN BASS

VOICE PIANO + BASS E.PIANO + BASS HARPSI + BASS VIBES + BASS BRASS + BASS STRINGS + BASS P.ORGAN + BASS
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.
