PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep this manual in a safe place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:
•Do not place the power cord near heat sources such as heaters or radiators, and
do not excessively bend or otherwise damage the cord, place heavy objects on
it, or place it in a position where anyone could walk on, trip over, or roll anything
over it.
•Only use the voltage specified as correct for the instrument. The required
voltage is printed on the name plate of the instrument.
•Use the specified adaptor (page 102) only. Using the wrong adaptor can result
in damage to the instrument or overheating.
•Check the electric plug periodically and remove any dirt or dust which may have
accumulated on it.
•This instrument contains no user-serviceable parts. Do not open the instrument
or attempt to disassemble or modify the internal components in any way. If it
should appear to be malfunctioning, discontinue use immediately and have it
inspected by qualified Yamaha service personnel.
•Do not expose the instrument to rain, use it near water or in damp or wet
conditions, or place containers on it containing liquids which might spill into
any openings. If any liquid such as water seeps into the instrument, turn off the
power immediately and unplug the power cord from the AC outlet. Then have
the instrument inspected by qualified Yamaha service personnel.
•Never insert or remove an electric plug with wet hands.
•Do not put burning items, such as candles, on the unit.
A burning item may fall over and cause a fire.
•Always replace all batteries at the same time. Do not use new batteries together
with old ones.
•Do not mix battery types, such as alkaline batteries with manganese batteries, or
batteries from different makers, or different types of batteries from the same
maker, since this can cause overheating, fire, or battery fluid leakage.
•Do not tamper with or disassemble batteries.
•Do not dispose of batteries in fire.
•Do not attempt to recharge batteries that are not intended to be charged.
•Keep batteries away from children.
•If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid
should come in contact with your eyes, mouth, or skin, wash immediately with
water and consult a doctor. Battery fluid is corrosive and may possibly cause
loss of sight or chemical burns.
•Always make sure all batteries are inserted in conformity with the +/ - polarity
markings. Failure to do so might result in overheating, fire, or battery fluid
leakage.
•When the batteries run out, or if the instrument is not to be used for a long time,
remove the batteries from the instrument to prevent possible leakage of the
battery fluid.
•When one of the following problems occur, immediately turn off the power
switch and disconnect the electric plug from the outlet. (If you are using
batteries, remove all batteries from the instrument.) Then have the device
inspected by Yamaha service personnel.
• The power cord or plug becomes frayed or damaged.
• It emits unusual smells or smoke.
• Some object has been dropped into the instrument.
• There is a sudden loss of sound during use of the instrument.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage
to the instrument or other property. These precautions include, but are not limited to, the following:
•Do not connect the instrument to an electrical outlet using a multiple-connector.
Doing so can result in lower sound quality, or possibly cause overheating in the
outlet.
•When removing the electric plug from the instrument or an outlet, always hold
the plug itself and not the cord. Pulling by the cord can damage it.
•Remove the electric plug from the outlet when the instrument is not to be used
for extended periods of time, or during electrical storms.
•Do not place the instrument in an unstable position where it might accidentally
fall over.
•Before moving the instrument, remove all connected cables.
•When setting up the product, make sure that the AC outlet you are using is
easily accessible. If some trouble or malfunction occurs, immediately turn off
the power switch and disconnect the plug from the outlet. Even when the power
switch is turned off, electricity is still flowing to the product at the minimum
level. When you are not using the product for a long time, make sure to unplug
the power cord from the wall AC outlet.

Connecting to a Computer
Nearly all of the electronic musical instruments made today—particularly synthesizers,
sequencers and computer music related devices—use MIDI. MIDI is a worldwide stan-
dard that allows these devices to send and receive performance and setting data. Natu-
rally, this instrument lets you save or send your keyboard performance as MIDI data, as
well as the songs, styles and panel settings.
The potential MIDI holds for your live performances and music creation/production is
enormous—simply by connecting this instrument to a computer and transmitting MIDI
data. In this section, you’ll learn the basics of MIDI and the specific MIDI functions pro-
vided by this instrument.
No doubt you have heard the terms “acoustic
instrument” and “digital instrument”. In the world
today, these are the two main categories of instru-
ments. Let’s consider a grand piano and a classical
guitar as representative acoustic instruments. They
are easy to understand. With the piano, you strike a
key, and a hammer inside hits some strings and
plays a note. With the guitar, you directly pluck a
string and the note sounds. But how does a digital
instrument go about playing a note?
As shown in the illustration above, in an electronic
instrument the sampling note (previously recorded
note) stored in the tone generator section (elec-
tronic circuit) is played based on information
received from the keyboard. So then what is the
information from the keyboard that becomes the
basis for note production?
For example, let’s say you play a “C” quarter note
using the grand piano sound on the instrument.
Unlike an acoustic instrument that puts out a reso-
nated note, the electronic instrument puts out infor-
mation from the keyboard such as “with what
voice”, “with which key”, “about how strong”,
“when was it pressed”, and “when was it released”.
Then each piece of information is changed into a
number value and sent to the tone generator. Using
these numbers as a basis, the tone generator plays
the stored sampling note.
Example of Keyboard Information
Your keyboard performance and all panel opera-
tions of this instrument are processed as MIDI
data. The songs, auto accompaniment (styles), and
User songs are also made up of MIDI data.
MIDI is an acronym that stands for Musical Instru-
ment Digital Interface and it allows different musi-
cal instruments and devices to instantly
communicate with each other, via digital data. The
MIDI standard is used all over the world and was
designed to transmit performance data between
electronic musical instruments (or computers).
Thanks to MIDI, you can control one instrument
from another and transmit performance data
between the devices-taking your creative and per-
formance potential to even higher levels.
MIDI messages can be divided into two groups:
Channel messages and System messages.
What Is MIDI?
●Acoustic guitar note production
Pluck a string and the body
resonates the sound.
●Digital instrument note production
Based on playing information from the keyboard, a sampling note
stored in the tone generator is played through the speakers.

Connecting to a Computer
●Channel Messages
This instrument is capable of handling 16 MIDI
channels simultaneously—meaning it can play up
to sixteen different instruments at the same time.
Channel messages transmit information such as
Note ON/OFF, Program Change, for each of the 16
channels.
●System Messages
This is data that is used in common by the entire
MIDI system. System messages include messages
like Exclusive Messages that transmit data unique
to each instrument manufacturer and Realtime
Messages that control the MIDI device.
The following functions become available when this instrument is connected to a computer.
● Performance data can be transferred between the instrument and the computer (page 87).
● Files can be transferred between the instrument and the computer (page 89).
The connection procedure is as follows:
1
Install the USB-MIDI driver on your com-
puter.
The USB–MIDI driver is included on the CD-ROM.
Installation of the USB MIDI driver is described on
page 92.
2
Connect the USB terminal of the computer
to the USB terminal on the instrument using
a standard USB cable (USB cable sold sep-
arately).
The supplied CD-ROM also includes a Musicsoft
Downloader application that allows you to transfer
song files from your computer to the instrument’s
flash memory. For instructions about how to install
Musicsoft Downloader and how to transfer song
files, see page 90.
■Precautions when using the [USB] termi-
nal
When connecting the computer to the [USB] termi-
nal, make sure to observe the following points.
Failing to do so risks freezing the computer and
corrupting or losing the data. If the computer or the
instrument freezes, restart the application software
or the computer OS, or turn the power to the instru-
ment off then on again.
