1. BEFORE PLAYING

A. Power Supply

The YPP-15 can be used with batteries or a
power adaptor connected to AC current.

1) Using Batteries

Remove the Battery Compartment Cover
on the underside of the keyboard. Insert 6
batteries (1.5V SUM-1, D-cells, or R20) into
the compartment, making sure their direc
tion (+/-) is correct. Replace the cover.

* Change all batteries at the same time.
* Use only the batteries listed above. Do not

use Ni-Cd or other kinds of batteries.

* Remove the batteries if the YPP-15 is not

going to be used for a long time.

2) Using AC Power

You will need a supplied YAMAHA PA-3
power adaptor. Make sure the YPP-15 is
turned off. Connect the adaptor to the DC
IN 10-12V jack on the rear panel. Please
note that YAMAHA will not be held re
sponsible for any problems caused by us
ing other, unauthorized adaptors.

D. Using Headphones

There are 2 HEADPHONES jacks on the
rear panel of the YPP-15. Connecting your
headphones to the HEADPHONES jack(s)
turns off the speakers, so 1 or 2 people can
practise and listen without disturbing any
body else.

another Audio System

If you want more volume, connect the L/R
AUX. OUT jacks of the YPP-15, using
suitable cables, to the inputs of a stereo,
keyboard amplifiers or a similar device. If
the device is monoaural, use the Left (L)
AUX. OUT jack of the YPP-15.

A. Basic Playing Operation

1) Power

When all the necessary connections have
been made, turn on the POWER switch (1).

2) Volume

Adjust the volume with the VOLUME slider
(2). This slider controls the speakers’ and
headphones’ volume, as well as the output
level of the AUX. OUT Jacks.

3) Selecting Voices

Select the sound you wish to play by pressing
one of the 5 Voice Select buttons (3).

When the YPP-15 is first turned on, PIAN01

is automatically selected.

4) Playing

Normally you can play up to 16 notes si
multaneously except for PIANO 2 which
can be played up to 14 notes at a time.
While depressing the foot switch connected
to the DAMPER jack, you can play up to 28
notes with any voice.

The tone of some voices may change slightly
at one or more points on the Keyboard. This
is due to the way in which the voice wave
forms were initially sampled and is normal.

o o o o o

B. Demonstration Play

1) Listening to the Demonstration

The YPP-15 has a demonstration song for
each voice. Press the yellow DEMON
STRATION button (4), and the demonstra

tion song for each voice will be played in

order from PIANO 1 to VIBES. This se
quence is repeated indefinitely.

* During demonstration piay, the Metronome

function wiii not be avaiiabie.

* The demonstration songs are not output as

MIDi performance messages (See section 4,
MiDi).

2) Stopping the Demonstration

To stop the performance, press the DEM
ONSTRATION button again.

3) Playing Individual Demonstration

Songs

If you wish to play the Demonstration Songs
individually, first press the DEMONSTRA
TION button. While holding it down, press
one of the Voice Select buttons. The song
corresponding to the selected voice will be
played once. If you wish to stop the per
formance, press the DEMONSTRATION
button again.

3. PLAYING TIPS & FEATURES

A. Touch Sensitivity

The YPP-15 is Touch Sensitive, which

means that the sound changes according
to the player’s touch. If you play harder, the
attack (initial phase of the sound) changes,
and the notes sound louder. There are 3

levels of touch resopnse, soft, medium and

loud. To adjust the sensitivity range, press
and hold the B5 and C6 keys, then press one
of Voice Select buttons PIAN01 (Range 1),

PIANO 2 (Range 2), E. PIANO (Range 3).

* When the YPP-15 is turned on, the sensitivity

range 2 is automaticaliy selected.

We recommend that you practise fine-tuning
your touch on the YPP-15, so as to achieve
maximum dynamic control and musical ex
pression.

B. Using the Metronome

To activate the metronome, press the M ET-

RONOME button (5). The initial tempo,
after the instrument has been turned on, is
always 120 beats per minute. The two
TEMPO buttons (6) are used to adjust the
tempo. To increase the tempo, press the
TEMPO A button, and hold it down until the
desired speed is reached. To decrease the
tempo, follow the same procedure with the
TEMPO T button. Pressing both TEMPO
buttons at the same time brings the tempo
back to 120. The range of the Metronome
is from 40 to 280 beats per minute. To turn
off the metronome, press the METRONOME
button again.

You can use the metronome to tighten your
playing, rhythmically, orto practise a musical
selection at different speeds.

C. TVansposition

The overall pitch of the YPP-15 can be
transposed up or down as far as 6 semitones.
Transposition occurs in 100 cent (1
semitone) steps.

You can use the Transposition function to

play a passage of music in several different
keys, without actually changing the notes

you play. Similarly, if you have to do some

playing (for instance, accompanying or

improvising) in a difficult key, you can
transpose the YPP-15 to that key, so that
the played C major scale (i.e. the white

notes) will sound like a scale in that key.

1) Raising the Pitch

To raise the overall pitch of the YPP-15,

press the MIDI/TRANSPOSE button (7).
While holding it down press one of the C*5
to F*5 keys (shown in the Front Panel Dia
gram).

D. Fine Tuning

This function is very useful if you are playing
in a band or other ensemble. It allows you
to tune your instrument with the others. The
YPP-15 can be fine-tuned up or down up to
a quarter tone (+/-50 cents). You can also
use the Fine Tuning function in conjunction
with the Transposition function, in either
order.

1) Raising the Pitch

While holding down both the Cl and D1
keys, press any one of the C3 to B3 keys.
Each time a key is pressed, the pitch will be

simultaneously, press any one of the C3 to
B3 keys. Or, you can turn off the POWER
switch, then turn it on again after a few
seconds.

4. MIDI

A. What is MIDI?

The YPP-15 is MIDI-equipped keyboard. MIDI

(Musical Instrument Digital Interface) is a worldwide

standard for communicating performance informa
tion between electronic musical instruments. With

MIDI, the YPP-15 can control, and be controlled by,

other MIDI-equipped instruments, such as synthe
sizers, sequencers and drum machines.

Note: If you connect more than two instruments, the

third instrument becomes the second Slave. To do
this, make an additional One-Way connection from
the MIDI-THRU jack of the first Slave to the MIDI-IN
jack of the second Slave:

DIAGRAM

In asimple MIDI setup between two instruments, the
instrument which is controlling is called the Master,
and the instrument being controlled is called the
Slave (Diagram A). You can also set up the two

instruments so that they control each other, i.e. both

machines are simultaneously Masters and Slaves

(Diagram B). To connect the YPP-15 to another

MIDI-equipped instrument, use the MIDI-IN or MIDI­OUT jacks on the rear panel, and join the instruments
as shown in Diagram A or B.

DIAGRAM

A

DIAGRAM

B

Diagram A depicts a “One-Way” connection, and

Diagram B depicts a “Hand-Shaking” connection.

All the following MIDI explanations will relate to
these terms, as well as to the terms Master and

Slave. So please be clear about all of these concepts

before proceeding.

At this time, the first Slave simply transmits, from its

MIDI-THRU jack, the information received at its
MIDI-IN jack. In this way, a Master can control two

Slaves simultaneously.

Note: that some MIDI instruments, such as the

YPP-15, are not equipped with a MIDI-THRU jack,
so are best used as the final Slave in a MIDI chain.

* Although MIDI Is a uniform standard, different instru

ments may have different specifications. Making the
MIDI connection Is not enough. The MIDI instruments or
devices must also have the same MIDI functions. If you

wish to know about the MIDI functions of a device, refer
to its MIDI Implementation Chart. The MIDI Implemen
tation Chart for the YPP-15 is on the last page of this

manual.

. Types of MIDI Informa

tion

What kind of information is communicated by MIDI?

The most universal is information about the notes

being performed (or played back) from the Master.

This is called “Note On” message, which includes

information about the key being depressed (trans
mitted as MIDI note number), and, in the case of
touch sensitive instruments such as the YPP-15, the

velocity (speed) of depression (transmitted as ve

locity data). For instance, when the YPP-15 is set up
as a Master, playing something on it will activate the
sound module of the Slave, and you will hear,
simultaneously, the voices of both instruments as
you play. If your Slave instrument is equipped to

receive the velocity data, the volume, timbre of its

voice will also vary according to your performance.

In addition to Note On information, the YPP-15 is

also equipped to deal with Program Change and

Control Change messages.

1) Program Change Message

Program Change message is used to change voices

on a Slave instrument. For instance, with the YPP-

15 set up as a Master, if you select one of its voices,

a Program Change message (including MIDI Pro
gram Number) will be transmitted to the Slave. If the
Slave has the MIDI capabilities to receive this

message, its own voice will be changed according to

the MIDI Program Number it has received. Con
versely, when the YPP-15 is the Slave, it can receive
the message and will automatically select its voice
according to the MIDI Program Number from the

Master.

The following chart shows the relation between
YPP-15 voices and MIDI Program Numbers.

cannot be transmitted or received.

Cancelling Program Change Message

Program Change message is automatically avail

able when the YPP-15 is turned on. Though it is a
very useful feature, you may sometimes run into a
situation where you wish to cancel it. To cancel

Program Change message, while holding down the
MIDI/TRANSPOSE button, press the Voice Select
button PIANO 2. To reactivate this message, repeat
the same procedure.

2) Control Change Message

Control Change message deals with various as
pects of the played sound. For instance, when
you’re using the YPP-15 as a Master and depress
the foot switch, a Control Change message (includ
ing MIDI Control Number and a Damper value) will
be transmitted to the Slave, so that the the Slave’s
sound will also be sustained (unless it cannot receive
the message). If the VPP-^5 is the Slave, it will
receive Control Change message instructions from
the Master.

Cancelling Control Change Message

Normally, Control Change message is automati
cally available when the YPP-15 is turned on. But
you may wish to create a situation where, for example,
the Slave YPP-15 sounds are not sustained in
tandem with the Master sounds. To cancel the
Control Change message, while holding down the
MIDI/TRANSPOSE button, press the Voice Select
button E. PIANO. To reactivate this message,
repeat the same procedure.

The above-described Note On, Program Change,
and Control Change messages are known as MIDI
channel information. That is, these messages are
communicated through MIDI channels. Sowhatare
MIDI channels? The next section addresses this
question.

The YPP-15, as a Master, can transmit only Damper
information (MIDI Control Number 64 in the follow
ing chart) As a Slave, however, it can receive a lot
more information, as shown in the chart above:

C. MIDI Channels

There are 16 MIDI channels (1-16). Unless MIDI
instruments are set to the same MIDI channel, they
cannot communicate MIDI channel information (Note
On, Program Change, Control Change, etc.), even
if the cables are connected properly. MIDI channels
can be likened to television channels, i.e. information
from several TV stations is transmitted through the
air, so to receive the desired program, you have to
select one channel on your TV set.

When the YPP-15 is turned on, both its transmitting
and receiving MIDI channels are setto 1. If required,
these channels can be reset.

1) Setting a MIDI Transmitting Channei

While holding down the MIDI/TRANSPOSE button,
press one of 16 keys from Cl to D^*2 according to the
table below.

>. Applications

The following three examples show how several of
the YPP-15’s MIDI functions can be applied in

specific setups. In order to make best use of MIDI,
it is important to determine which instruments are
most effective as Masters or as Slaves. This will

depend on the individual situation. Consulting the

MIDI implementation chart of each instrument in
your setup will help you to decide in each case. If
one instrument has more transmission capabilities
than the other(s), it will generally be better suited as
the Master. Conversely, instruments with more

recognition capabilities will be better Slaves.

Example 1: Using the YPP-15 with another key

board or sound module

If you are a MIDI rookie, first, make a Hand-Shaking

connection between the two MIDI keyboards. After

matching the transmitting and receiving MIDI

channels (in both directions), you can use either

instrumentas Master or Slave. Whichever keyboard
you play, you will hear the sounds of both instruments.

In addition, the Slave will duplicate the Master’s

sustain, etc., as long as it is equipped to receive MIDI

messages such as Program Change, Control

Change, and so on.

* Practising with a Hand-Shaking connection is a good

way to learn which instrument will make the better
Master or Slave in a One-Way connection.

3) Omni On Mode

If required, the YPP-15 can be set to receive infor
mation on all MIDI channels (1-16). This mode is

called “Omni On”. To set the YPP-15 to this mode,
while holding down the MIDI/TRANSPOSE button,
press the E4 key. To get out of this mode, either
select a specific receiving channel, or turn off the
YPP-15, then turn it on again after a few seconds.

Note: If you have several Slaves, all set to OMNI

Mode, they will all receive the same instructions, and
therefore play the same music. To achieve individual
control of the Slaves, that is, to get each one to

respond to different instructions and play its own
part in an ensemble, you must set the Slaves’ MIDI

receiving channels individually. When a specific
channel is selected, it means the instrument is in

OMNI OFF Mode.

* If you’re connecting the YPP-15 to a MIDI sound module,

the latter is best used as a Slave in a One-Way connec
tion.

Example 2:

Using the YPP-15 with a drum ma-

Examples: Using the YPP-15 with a sequencer

(and other keyboards)

If you have a MIDI-compatible rhythm/drum ma
chine, use It as a Slave of the YPP-15. After
matching MIDI channels, play the YPP-15 key
board. Now you can have various percussion sounds
at your fingertips. Playing a key on the YPP-15 will
transmit a specific MIDI Note Number to the drum
machine, which reproduces the percussion sound
corresponding to it.

Here’s another idea: If your drum machine includes
a melody instrument such as bass or vibraphone,

you can access this sound from the YPP-15. First,

look up the MIDI receiving channel assigned for
controlling the sound. Then, set both instruments to

this channel. You can now play the drum machine’s

melody instrument sound from the YPP-15. If you

wish, you can accompany your performance with a

rhythmic pattern (start/stopped locally on the drum
machine). Yourentire performance can be input into

the drum machine as rhythm data.

DIAGRAM

Knowing how to use the YPP-15 effectively with a
sequencer makes you a MIDI pro!

After you’ve recorded all the parts of your perfor

mance on the sequencer, you’ll want to play back
your ensemble, with each part matched (via MIDI
channels) to the appropriate instrument or sound

module. Say you’ve recorded a two-part ensemble,
cello and flute, on MIDI channels 1 and 2, each
channel matched to a separate instrument or sound

module in your MIDI system (instruments A and B in
the Diagram below). When you play back the
ensemble, you may wish to experiment with the
sounds. Here’s one thing you can try: put the YPP-

15 (one of the Slaves in your setup) in OMNI ON

Mode, and select the voice you wish, say PIANO 1.
Thus, the YPP-15 will receive performance data in

both of MIDI channels 1 and 2, and so will play back

both parts in PIAN01 voice, as a complement to the
cello and flute sounds from instruments A and B.

Another use of OMNI ON Mode is for checking the
contents of an unlabelled performance data disk whose
MIDI channels are unspecified. After loading the data
into the sequencer, transmit it from the sequencer to the
YPP-15 in OMNI ON Mode. Regardless of the MIDI
channels to which the data was assigned, the YPP-15 In
OMNI ON Mode will play it back.

If you set up a Hand-Shaking connection between

the YPP-15 and the sequencer, there are two things
to be noted:

If the sequencer is set to transmit the same MIDI infor
mation as received at its MIDI IN jack (This is called
“Echo On”, “Soft Thru On”, etc., depending on the

make), set the YPP-15 to “Local Control Off If you
fail to do this, pressing a single key will sound twice as
many notes as in normal play. As a result, it will reduce
the polyphonic notes you can play at a time.

Conversely, when the sequencer is set to “Echo Off”
(“Soft Thru Off”, etc.), you cannot play directly from the
keyboard If it is in “Local Control Off”, because the
sequencer doesn’t retransmit any received MIDI data. In
this case, you have to set the YPP-35 to “Local Control
On”, which enables you to control the sound module
from either the keyboard or the sequencer.

(*1) Local Control On/Off: Normally, the YPP-15’s

keyboard is connected to its internal sound module,
which means that when you play, a sound is output
from the instrument, and when you select a different
voice, the sound changes. This state is called “Local
Control On”. However, if desired, the YPP-15 can
be set to “Local Control Off.” In this state, the
keyboard is disconnected from the sound module,
which means that if you play something, a sound will

not be produced from the instrument itself, but your
performance can be transmitted via MIDI to an
external instrument.

Local On

- Setting to Local Control Off

While holding down the MIDI/TRANSPOSE button,
press Voice Select button PIANO 1. To return the
YPP-15 to Local Control On, repeat the same pro
cedure.

One of the most exciting features of the YPP-15 is
that it is capable of playing all of its five voices at the
same time. This feature is called Multi-timbre, and
is most useful when using the YPP-15 as a Slave
from a sequencer.

The YPP-15 has two play modes: Normal and Multi
timbre. When the instrument is turned on, it is

always in Normal mode, that is, you play a single

voice on the keyboard. When in Multi-timbre mode,

however, the YPP-15 will act as ten independent
sound modules, with all 5 preset voices available for
use in an ensemble performance.

- Entering Multi-timbre mode

While holding down the MIDI/TRANSPOSE button,
press the HARPSICHORD Voice Select button. To
exit from Multi-timbre mode, repeat the same op
eration once again.

Now, try using the YPP-15 in Multi-timbfe mode with
a sequencer(*).

* To best use the YPP-15 in Multi-timbre mode, you will

need a Master device which can control other devices
with different MIDI channels at the same time. This could
be a sequencer, MIDI-equipped personal computer, or
MIDI master keyboard.

The following diagram relates to a Hand-Shaking
connection between a YPP-15 and a sequencer.
Try going quickly through the following steps, to

become familiar with the use of Multi-timbre mode.
The object is to record an ensemble performance of
several parts onto the sequencer, then play it back
with each part sounding in a different YPP-15 voice.

YPP-15

Step 1: Set the YPP-15 in Multi-timbre mode.

Step 2: Ensure the YPP-15 is set to Local Control

On and the sequencer to Echo Off, or the YPP-15 to
Local Control Off and the sequencer to Echo On.
Remember the notes on page 12.

Step 3: Select a MIDI transmitting channel from 1 -

10(*) on the YPP-15, then select the voice you

desire. You should set the transmitting channel

before playing, so that the sequencer will receive all

the information, via MIDI channel message, regarding
voice, touch, sustain, etc.

* In Multi-timbre mode, the YPP-15’s sound module can

receive MiDI messages In channels 1 -10. MIDI messages
in channels 11-16 cannot control the YPP-15’s sound
module. Additionally, when you enter Multi-timbre mode,

preset voices are automatically assigned to MIDI chan
nels, as shown in the following chart:

Step 4: Play one of the ensemble parts on the

keyboard, pedalling as needed, and record it onto

one of the tracks of the sequencer. You may, of
course, change voices during play.

Step 5: Repeat Steps 3 and 4 as needed. In each

case, selectthe appropriate MIDI channel (according
to the voice desired for that part) before Step 3, and

in Step 4, record onto a new track or overdub onto

previously recorded tracks.

Step 6: Play back the completed ensemble per

formance from the sequencer. You will hear the
different voices, corresponding to the different parts
of the ensemble, played out simultaneously.

MAINTENANCE

• Every once in a while, wipe the cabinet clean with a soft cloth slightly moistened with a diluted soap solution,
then wipe it with a dry cloth. Don’t use chemically treated cloths or other chemicals like oil, solvents or

insecticides.
