Congratulations and thank you for purchasing the Yamaha MU10
Tone Generator!
Welcome to the MU10
The MU10 is a sophisticated, yet highly compact MIDI tone
generator, specially designed for use with computers and MIDI music
systems.
With the built-in host computer interface and MIDI terminals,
the MU10 is ideal for any computer music system — from connection
to a simple laptop to integration in a complete MIDI studio. The host
computer interface is especially convenient, allowing you to directly
connect it to your computer without the need for a special MIDI
interface.
Featuring Yamaha’s high quality AWM2 tone generation technol-
ogy, the MU10 has 676 Normal Voices and 21 Drum Voices (percus-
sion sets), with full General MIDI compatibility — including
Yamaha’s new XG-MIDI. It provides 16-Part multi-timbral capac-
ity and full 32-note polyphony for playback of even the most sophis-
ticated song data. Three independent digital effect sections — with
11 types of Reverb, 11 types of Chorus, and 43 different Variation
effects — can be used simultaneously and give you enormous versatil-
ity in “sweetening” the sound. Plus, the MU10 has two convenient A/
D INPUT jacks, allowing you to connect external audio sources
(such as a microphone, guitar, or CD player), and mix those sources
with the AWM2 Voices of the MU10.
Because of all the above, as well as its exceptionally portable size
and convenient battery/AC adaptor power supply, the MU10 is an
invaluable tool for all MIDI musicians and performers.

The MU10 — What It Is and What It Can Do
What It Is
The MU10 is a compact, highly portable MIDI tone generator, designed
especially for use with computers and MIDI music systems. Specifically, it
is a high-quality XG- and GM-compatible tone generator, with 676 Voices
and 21 drum Voices (percussion sets). The tone generator can be played
either from an external MIDI device (such as a keyboard or a sequencer) or a
computer. The MU10 also includes three independent digital effect sections
— with 11 types of Reverb, 11 types of Chorus, and 43 different Variation
effects — for enhancing the sound of the Voices.
The MU10 features a built-in host computer interface, allowing you to
directly connect it to your Macintosh or IBM PC/AT (and compatible)
computer—eliminating the need of installing a special MIDI interface to your
computer. With the proper sequencing software on the computer, the MU10
can be used for both recording and playing back of sequencer data. The
internal tone generator also allows for comprehensive control over all Voice
and effect parameters — via incoming system exclusive messages, transmit-
ted from a sequencer or other MIDI device. (Refer to the MIDI Data Format
section on page 25 for details on controlling various MU10 parameters.)
The MU10 also features two convenient A/D INPUT jacks, allowing you to
connect external audio sources and mix those sources with the Voices.
Moreover, the built-in effects can be applied to the external sources as well
as the internal AWM2 Voices.
The MU10 is also the latest instrument in the Yamaha line to support the XG
format, a new addition to the General MIDI standard. In short, XG provides
for more instrument sounds and variations, and greater expressive control
over voices and effects.

The MU10 — What It Is and What It Can Do
What It Can Do
Here are a few application ideas on how you can use the MU10. The list
below is not comprehensive, but is meant to be a general guide to the
possibilities and provide a starting point or springboard for your own creative
ideas and explorations.
■Using in a MIDI Music System
Connect the MU10 to a computer with MIDI sequencing software, and
you’ve got comprehensive music making power—for recording, composing,
arranging, practicing, and editing. Combine it with a laptop computer, and
you’ve got a complete and portable music production system that’s ready to
go wherever you go. The built-in A/D Inputs let you connect an external
audio source (such as a microphone or guitar), allowing you to play along
with the MIDI tracks.
The MU10 is an ideal addition to larger MIDI studios as well, since it gives
you a high-quality 16-Part multi-timbral tone generator.
■Multimedia
Since it’s portable and compatible with the XG and General MIDI formats,
the MU10 is a natural for multimedia applications. Because of its portability
and great sound, it’s the only tone generator you’ll need for recording,
editing and playing back MIDI data on your multimedia creations.
■Using With a MIDI Keyboard in Live Performance
Simply connect the MU10 to a MIDI keyboard and play the dynamic Voices
in live performance situations. With the built-in A/D Inputs, you can even
use the MU10 as a simple 2-channel mixer. Bring a computer or MIDI data
player to your gig, and you can even mix another instrument (such as guitar
or bass) with the MIDI-driven Voices of the MU10.

Setting Up the MU10 in Your Music System
Whatever your system, you should follow the basic instructions in this section when
setting up your MU10. Use the example illustrations as a general guide when making
the connections with your own system.
Setting Up Your MU10
Power Supply
■Using a Power Adaptor
Connect one end of the power adaptor
(optional Yamaha PA-3B, PA-1207, or
equivalent) to the DC IN jack on the
rear panel, and the other end to a
suitable electrical outlet.
Your MU10 will run either from an optional AC adaptor or batteries. When-
ever possible, you should use the AC adaptor, since the MU10 runs only for
a short time on battery power (approximately two hours and twenty minutes
on alkaline batteries).
■ NOTE
●Before making any connections, make
sure that all equipment to be con-
nected is turned off.
■ CAUTION
●Do not attempt to use an AC adaptor
other than the PA-3B, PA-1207, or
equivalent. The use of an incompatible
adaptor may result in irreparable
damage to the MU10, and even pose a
serious shock hazard. (The recom-
mended power adaptor may vary,
depending on your location. Please
consult your nearest Yamaha dealer for
details.)
●Be sure to disconnect the power adaptor
from the outlet when the MU10 is not in
use for an extended period of time or
during electrical storms.

Setting Up Your MU10
■Using Batteries
To use the MU10 on battery power,
remove the battery compartment cover
(as shown at the right) and insert six
1.5V AA size (SUM-3, R-6 or equiva-
lent) manganese or alkaline batteries
in the battery compartment. Make
sure to follow the polarity indications
on the bottom case.
Securely replace the battery compart-
ment cover when finished installing
the batteries.
■When to Replace the Batteries
When the battery power runs too low to properly operate the MU10, the
POWER lamp will flash slowly. When this happens, replace all batteries
with a complete set of six new batteries of the same type.
■ CAUTION
●NEVER mix old and new batteries or different types of batteries! Also, to
prevent possible damage due to battery leakage, remove the batteries from the
instrument if it is not to be used for an extended period of time.
●The MU10 has no memory backup function. Turning the power off will auto-
matically initialize all settings and parameter values.
