KEYBOARD STAND ASSEMBLY

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.
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.
2. Initially set the MASTER VOLUME control about three quarters of the way towards the MAX setting. Then, when you start playing, adjust the VOLUME control for the most comfortable listening level.
3. Select the desired voice by pressing one of the voice selectors.
4. Play. 2. Slide the MASTER VOLUME control to a position about three quarters of the way towards the MAX setting. You can set this control for the most comfortable volume level after playback begins.
Note: The Personal Electronic Piano has 8-note polyphony which means you can play up to 8 notes at once. If you activate the Bass Split mode, up to two notes can be played on the lower (bass) section of the keyboard and up to six notes can be played on the upper fright-hand) section (see Voice Selectors- The Bass Split Mode on page 7). The Metronome also uses one note, so up to seven notes can be played on the keyboard while the metronome is running (the metronome uses one note of the righthand keyboard section when the Bass Split mode is active). The Personal Electronic Piano also offers keyboard touch response, so the volume and timbre of notes played can be controlled according to how hard you play the keys. The amount of variation available depends on the selected voice.

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.

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.

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.

This series of Yamaha Personal Electronic Piano uses frequencies that appear in the radio frequency range, and if installed in the immediate proximity of some types of audio or video devices within three meters (approximately ten feet), interference may occur. This series of Yamaha Personal Electronic Piano has been type-tested, and found to comply with the specifications set for a class B computer in accordance with those specifications listed in sub-part J, part 15 of the FCC rules. These rules are designed to provide a reasonable measure of protection against such interference. However, this does not guarantee that interference will not occur. If your Personal Electronic Piano should be suspected of causing interference with other electronic devices, verification can be made by turning your Personal Electronic Piano off and on. If the interference continues when your Personal Electronic Piano is off, the Personal Electronic Piano is not the source of the interference. If your Personal Electronic Piano does appear to be the source of the interference, you should try to correct the situation by using one or more of the following measures: l Relocate either the Personal Electronic Piano or the electronic device that is being affected by the interference. l Utilize power outlets for the Personal Electronic Piano and the device being affected that are on different branch (circuit breaker or fuse) circuits, or install a/c line filters. l In the case of radio-TV interference, relocate the antenna or, if the antenna lead-in is a 300 ohm ribbon lead, change the lead-in to coaxial type cable. If these corrective measures do not produce satisfactory results, please contact a Yamaha dealer for suggestions and/or corrective measures. If you can not locate a Yamaha dealer in your general area, please contact the Service Division, Yamaha Corporation of America, 6600 Orangethorpe Ave., Buena Park, CA 90620, U.S.A.
