Welcome to the MU15

Congratulations and thank you for purchasing the Yamaha MU15 Tone Genera­tor!
The MU15 an advanced, yet easy-to-use tone generator providing exceptionally high-quality Voices, built-in effects, XG format and General MIDI (GM) compat­ibility, plus direct connection to computer — all in a highly compact and portable package.
With the built-in host computer interface and MIDI terminals, the MU15 is ideal for any computer music system — from connection to a simple laptop to integration in a complete MIDI studio. It even features a two-octave keyboard (with adjustable ten-octave range), allowing you to play the internal Voices and enter notes to a connected sequencer. Since it’s compatible with Yamaha’s powerful XG format, it lets you faithfully and easily playback any XG or GM song data.
The MU15 also features 16-Part multi-timbral capacity and full 32-note poly­phony for playback of even very sophisticated, multi-part song data. Three independent digital effect sections give you enormous versatility in “sweeten­ing” the sound. What’s more, the MU15 provides a host of comprehensive editing tools for getting just the sound you need.
4
GM System Level 1
“GM System Level 1” is a standard specification that defines the arrangement of voices in a tone generator and its MIDI functionality, ensuring that data can be played back with substantially the same sounds on any GM-compatible tone generator, regardless of its manu­facturer or model. Tone generators and song data that meet the “GM System Level 1” bear this GM logo.
XG
“XG” is a tone generator format that expands the voice arrangement of the “GM System Level 1” specification to meet the ever-increasing demands of today’s com­puter peripheral environment, providing richer expres­sive power while maintaining upward compatibility of data. “XG” greatly expands “GM System Level 1” by defining the ways in which voices are expanded or edited and the structure and type of effects. When commercially available song data bearing the XG logo is played back on a tone generator which bears the XG logo, you will enjoy a full musical experience that includes unlimited expansion voices and effect func­tions.

The MU15 — What It Is and What It Can Do
The MU15 — What It Is and
What It Can Do

What It Is...

The MU15 is a compact, highly portable and easy-to-use tone generator. It features XG compatibility with a stunning variety of 480 XG Voices (including 128 GM Voices) and 11 Drum Voices (with Drum and SFX kits).* The MU15 has 32-Voice polyphony and is 16­Part multi-timbral. In other words, the MU15 has 16 different Parts, each with its own Voice, so that up to 16 different Voices can be sounded simultaneously.
With the built-in two-octave keyboard, you can play any of the Voices directly from the MU15 itself. Or you can play them from a con­nected MIDI keyboard. In addition, the MU15 also has a TO HOST terminal for easy interfacing with a computer, allowing you to play the Voices using your favorite music software. This is where the advanced multi-timbral capabilities come in, letting you play up to 16 different Voices at the same time.
* The MU15 has a total of 676 different Voices. A separate
TG300B mode (page 43) features 579 Voices, some of which are diiferent than the XG set.

What It Can Do...

Here are a few ideas on how you can use the MU15. 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.
Carry It With You
If you have a laptop computer (and sequencing software), simply connect the MU15, plug in some headphones and you’ve got a complete music making system that’s ready to go wherever you go.
10
The MU15 — What It Is and What It Can Do
Use it for composing, arranging, practicing or making/playing demos for your band.
Perform With It
Bring it with you to a gig — as long as there’s a MIDI keyboard on stage, you can use the high-quality sounds of MU15 in your perfor­mance.
Multimedia
Since it’s portable and compatible with General MIDI, the MU15 is a natural for multimedia applications. Bring it with you to a presenta­tion — since the computer interface is built-in to the MU15, it hooks up instantly and easily to the computer’s serial port without the need for any other equipment.
Using With MIDI Keyboard
Use the MU15 as supplementary tone generator with your MIDI keyboard and play the Voices of both instruments in a layer together. Or, if your keyboard has the capability, program a “split” so that the notes you play on the right side of the keyboard play only the Voices of the MU15.
English
Using With Other MIDI Controllers
Even if you’re not a keyboard player, you can still play the MU15 with other types of MIDI controllers. For example, use a MIDI percussion controller to play the drum and percussion sounds of the MU15. Guitar controllers (such as the Yamaha G50) or wind controllers (such as the Yamaha WX5) are also available for players of those instru­ments.
Home Studio Setup
The MU15 integrates easily into any existing setup. If you have a MIDI keyboard, computer and sequencing software, the MU15 with its high-quality Voices and multi-timbral capabilities can expand your home studio system.

The MU15 — What It Is and What It Can Do

About General MIDI (GM)

General MIDI (GM) is a new addition to the worldwide MIDI stan­dard. MIDI, as you know, stands for Musical Instrument Digital Interface, and makes it possible for various electronic musical instruments and other devices to “communicate” with each other. For example, by connecting a sequencer to the MU15’s MIDI IN terminal, you could play back a song on the sequencer using the Voices of the MU15.
So, where does GM fit in all of this? One of the most important features of General MIDI is in the standardization of Voices. This means that a song recorded in the GM standard can be played back on any GM-compatible tone generator and sound just as the com­poser intended. For example, if there is an alto sax solo in the song, it will be played by an alto sax Voice on the General MIDI tone generator (and not by a tuba or harpsichord!). Since the MU15 is fully GM-compatible, you can take advantage of the vast wealth of musical material recorded in that format.

About XG

The Yamaha XG format is an extension of General MIDI, and pro­vides a number of significant improvements and enhancements. XG­compatible song data takes advantage of the expanded Voice set, extensive MIDI control and built-in effects of the MU15 (as well as other MU-series instruments).
To get the most out of XG and your MU15, we recommend using XG-compatible instruments and software. For example, the Yamaha CBX-K2 keyboard lets you dynamically control a variety of param­eters in real time while you play. The XGworks sequencer software not only lets you playback GM- or XG-compatible song data, it lets you record your own songs — and gives you enormously powerful and easy-to-use editing tools for adjusting detailed settings of the MU15 that are unavailable with the panel controls.

Guided Tour

Guided Tour
When using your MU15 for the first time, read through this short section of the manual. It guides you step-by-step in using many of the basic operations: setting the instrument up, connecting it properly to other equip­ment, and — most importantly — playing it. It also intro­duces you to most of the other, advanced features and operations of the instrument — enabling you to quickly and effectively get the most out of your new MU15.

Setting Up Your MU15

Since the MU15 has a built-in keyboard, you could use it with nothing more than a set of batteries and a proper set of stereo headphones. It can also be used effectively with a computer in a “desktop music” system.
English
In this section, however, you’ll learn how to connect the MU15 in a basic system with a MIDI keyboard and an external amplifier/speaker system. (For basic information on MIDI and its applications, see page 91.)

What You’ll Need

• The MU15 and a proper power supply (either an AC adaptor or batteries).
• A MIDI keyboard, electronic piano, or any instrument that can output MIDI data.
• An amplifier speaker system, preferably stereo. Alternately, you can use a set of stereo headphones.
• Audio connecting cables.
• A MIDI cable.
17
Setting Up Your MU15

Power Supply

Although the MU15 will run either from an optional AC adaptor or batteries, Yamaha recommends use of an AC adaptor whenever possible. Moreover, an AC adaptor is more environmentally friendly than batteries and does not deplete resources.
CAUTION
Before making any connections, make sure that all equipment to be connected is turned off.
Using a Power Adaptor
Connect one end of the power adaptor (Yamaha PA-3B) to the DC IN jack on the rear panel, and the other end to a suitable electrical outlet.
WARNING
Do not attempt to use an AC adaptor other than the PA-3B. The use of an incompatible adaptor may result in irreparable damage to the MU15, and even pose a serious shock hazard.
CAUTION
When connecting the AC power adaptor, first make sure that the MU15 is turned off (set to STANDBY). Next, connect one end of the power adaptor to the DC IN jack on the MU15, and connect the other end to an appropriate AC outlet.
The MU15 has a convenient data backup feature that maintains any changes you’ve made to the settings, even when the power is turned off. However, removing the batteries or disconnecting the AC adaptor automatically clears the data and restores the factory defaults. To save your important data, use the Dump Out function (page 65).
18
Setting Up Your MU15
Using Batteries
To use the MU15 on battery power, insert six 1.5V AA size (SUM-3, R-6 or equivalent) manganese or alkaline batteries in the battery compartment. Make sure to follow the polarity indications on the bottom case (and as shown below).
Securely replace the battery compartment cover when done install­ing the batteries.
When to Replace the Batteries
When the battery power runs too low to operate the MU15, the sound may become distorted and the following display will appear:
English
Battery
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.
19
Setting Up Your MU15

Making the Connections

CAUTION
Before making any connections, turn all related equipment off, and make sure the MU15’s power adaptor is not connected to an electrical outlet.
Operation
Z Connect the MIDI cable.

Selecting Voices

The MU15 has a total of 676 different instrument Voices. Here, we’ll select a different Voice for playing.
Each Voice is numbered, and there are 128 Voices from which you can immedi­ately select. (We’ll see how to select Voices outside of these 128 later.)
Operation
Use the VALUE buttons.
Pressing the VALUE /YES button steps up through Voice numbers while pressing the VALUE /NO button steps down through the numbers.

Hold either button down to move rapidly through the numbers in the selected direction. To move even more quickly through the num­bers, simultaneously hold down one button, and then press (or hold down) the other. For example, to rapidly decrease the value, simulta­neously hold down the
/NO button and press the /YES button.

About Parts, Voices, and Banks

Before we go on to the next section, a little explanation about the organization of the MU15 is needed. Here, you’ll learn about Parts, Voices, and Banks — three important concepts around which the sounds of the MU15 are organized.

Voices
As mentioned in the section “The MU15 — What It Is and What It Can Do,” the MU15 is capable of playing sixteen different instru­ment sounds at the same time. Each instrument sound is called a “Voice,” and the MU15 has 676 different Normal Voices, as well as 21 Drum Voices.
Let’s say, for example, you have a song in which you want to use the following sixteen Voices:
Grand Piano Pick Bass Steel Guitar Rock Organ
Tenor Sax Alto Sax Trumpet Flute
Marimba Drums Violin Cello
Strings Warm Pad Sweep Pad Saw Lead
Parts
For these Voices to be used simultaneously, they must be assigned to different “Parts.” These correspond exactly to the parts of a song or the elements of a band, such as bass, guitar, and drums.
English
Part 1 Part 2 Part 3 Part 4 Grand Piano Pick Bass Steel Guitar Rock Organ
Part 5 Part 6 Part 7 Part 8 Tenor Sax Alto Sax Trumpet Flute
Part 9 Part 10 Part 11 Part 12 Marimba Drums Violin Cello
Part 13 Part 14 Part 15 Part 16 Strings Warm Pad Sweep Pad Saw Lead
Obviously, each Part can have its own Voice setting, but it can also have independent settings for other aspects of the sound as well, as we’ll see later.
NOTE
Part 10 is normally reserved for Drum Voices, although this can be changed. (Page 28.)

Playing the MU15
Banks
As you learned in “Selecting Voices” above, each Voice is numbered, and there are 128 of them from which you can select. These 128 Voices make up a Voice “Bank.” The MU15 has many Banks, each of which contain 128 Voices. By selecting a different Bank, you can select different Voices — any of the 676 Voices available on the MU15.
Now, let’s go on to the next sections and see how to select different Parts, and how to select Voices on the other Banks.

Selecting Parts

In “Selecting Voices” above, you learned how to select a Voice. Here, you’ll see how to select a different Part and select a different Voice for that Part.
Operation
Z Select the desired Part by using the PART buttons.
Pressing the PART button steps up through the Part numbers while pressing the PART button steps down through the num­bers.
Part number
Hold either button down to move rapidly through the numbers in the selected direction.
X Select a Voice for the current Part.
Do this in the normal way, by using the VALUE buttons.

Selecting Banks

As you learned in “About Parts, Voices, and Banks” above, the MU15’s 676 Voices are organized into Banks of 128 Voices each. Here, we’ll see how to select Voices of different Banks.
Operation
Z Select the desired Part.
Do this in the normal way, by using the PART buttons.
X Select the desired Voice.
Do this in the normal way, by using the VALUE buttons.
In general, the Voice Banks feature variations on the basic Voices — for example, the “PercOrgn” Voice has several similar sounding organ Voices at the same Voice number, but in different Banks. That’s why it’s a good idea to decide which type of Voice you want, and then call up different Banks to select a specific Voice variation.
C Simultaneously hold down the XG BANK button and
press one of the VALUE buttons.
English
Holding down the XG BANK button and pressing the VALUE button steps up through Bank numbers while doing the same with the VALUE /NO button steps down through the numbers.
Notice that the Bank numbers jump to seemingly random values. For example, if you’ve selected Voice number 005 “E.Piano1,” holding down the XG BANK button and pressing the VALUE button will step through the following Banks:
GrndPnoK
Bank number. (This changes to the Voice number as soon as the XG BANK button is released.)
/YES
/YES

E.Piano1
El.Pno1K
MelloEP1
Chor.EP1
In this way, the MU15 skips over Banks that have the same Voices as the basic Bank (Bank 000), and lets you automatically jump to Banks that have unique Voices for the selected Voice number. In the above example, Banks 002 - 017 all have the same Voice for number 005: “E.Piano1.” Bank 018 has a unique Voice, followed by another unique Voice at Bank 032, and so on.
NOTE
When the SFX kit (XG Bank #126) or Drum kit (XG Bank #127) is selected , the Voice number is automatically set to 001.
…and so on.

Playing Drum Voices

The MU15 also features a wide selection of dynamic, realistic drum and percussion sounds. These sounds are grouped together in Drum Voices and each note on the keyboard plays a different drum or percussion sound.
NOTE
For details on which drum sounds are assigned to which notes of the keyboard, refer to the Drum Map charts on pages 80 - 83.
Operation
Z Select Part 10.
Do this in the normal way, by using the PART buttons.
NOTE
Part 10 is assigned to a Drum Voice by default. However, any Part can be set to a Drum Voice by selecting Bank 126 or 127 for the Part.
28
Playing the MU15
X Select the desired Drum Voice.
Do this in the normal way, by using the VALUE buttons.
C Play the drum sounds.
Play the sounds from the MU15’s keyboard or from a connected MIDI keyboard.
Since the various drum/percussion sounds are spread out over several octaves, in order to play them from the MU15, you’ll need to change the octave setting (see next section).

Changing the Octave Setting

Although the MU15’s built-in keyboard has a two-octave range, you can actually play it over a range of ten octaves.
Operation
Use the OCT DOWN / OCT UP buttons.
Pressing the OCT DOWN button lowers the pitch by one octave, and pressing the OCT UP button raises it by one octave. The current octave setting is shown in the display. (No indication appears when the octave setting is normal.)
English
Current octave setting. (In this example, the pitch is two octaves above normal.)
NOTE
For Normal Voices (such as Piano or Strings), this changes the pitch. For Drum Voices, this changes the drum/percussion sounds playable from the keyboard.
You can instantly restore the normal octave setting by pressing both OCT DOWN / OCT UP buttons simultaneously.

Editing a Part

The editing features of the MU15 provide various controls for changing the Parts and setting other important operating functions. Among other things, these let you set the Volume or Pan setting of each Part independently, change the Velocity of the built-in keyboard, and save your edits to a connected computer, sequencer or data storage device.
NOTE
The Velocity and Local Control settings cannot be saved.
Editing on the MU15 is basically divided into three types of controls: Part, Effect, and Utility. In this section, you’ll learn how to change the Note Shift setting and the Volume setting (both Part controls). However, the instructions given here are fundamentally the same for all editing operations. (See the Reference section of this manual for information about the specific editing functions.)
Changing the Note Shift and Volume Settings
The Note Shift parameter lets you change the key (pitch) of the selected Part. This only affects the Normal Voices, and does not change the pitch of the Drum Voices.
The Volume parameter allows you to change the level of each Part’s Voice, letting you set a custom balance or mix of all the Parts.
Operation
Z Select the desired parameter.
For Note Shift, simultaneously hold down the PLAY/EDIT button and press the NOTE SHFT button. Doing this enters the Edit mode and calls up the Note Shift parameter.
