Installing Optional Hardware
Available devices 
The following optional devices can be installed to the MOTIF ES.
Installation locations
Installation Precautions
Before installing the optional hardware, make sure you have a Philips screwdriver and ample space to work. Protective cushions 
or supports for the instrument may also be needed.
•Before beginning installation, switch off the power to the instrument and connected peripherals, and unplug them from the power outlet. Then remove all 
cables connecting the instrument to other devices. (Leaving the power cord connected while working can result in electric shock. Leaving other cables 
connected can interfere with work.) Installation or removal of any devices should be started ONLY after the instrument (and the optional hardware) 
returns to normal room temperature.
•Be careful not to drop any screws inside the instrument during installation (this can be prevented by keeping the optional units and cover away from the 
instrument while attaching). If this does happen, be sure to remove the screw(s) from inside the unit before turning the power on. Loose screws inside 
the instrument can cause improper operation or serious damage. If you are unable to retrieve a dropped screw, consult your Yamaha dealer for advice.
•Install the optional units carefully as described in the procedure below. Improper installation can cause shorts which may result in irreparable damage 
and pose a fire hazard.
•Do not disassemble, modify, or apply excessive force to board areas and connectors on optional units. Bending or tampering with boards and 
connectors may lead to electric shock, fire, or equipment failures.
•Before handling the optional units, you should briefly touch the metal surface to which the optional unit cover is attached (or other such metallic area  be 
careful of any sharp edges) with your bare hand so as to drain off any static charge from your body. Note that even a slight amount of electrostatic 
discharge may cause damage to these components.
•It is recommended that you wear gloves to protect your hands from metallic projections on optional units and other components. Touching leads or 
connectors with bare hands may cause finger cuts, and may also result in poor electrical contact or electrostatic damage.
•Handle the optional units with care. Dropping or subjecting them to any kind of shock may cause damage or result in a malfunction.
•Be careful of static electricity. Static electricity discharge can damage the IC chips on the Plug-in board. Before you handle the optional Plug-in board, to 
reduce the possibility of static electricity, touch the metal parts other than the painted area or a ground wire on the devices that are grounded.
•Do not touch the exposed metal parts in the circuit board. Touching these parts may result in a faulty contact.
•When moving a cable, be careful not to let it catch on the circuit Plug-in board. Forcing the cable in anyway may cut the cable, cause damage, or result in 
a malfunction.
•Be careful not to misplace any of the screws since all of them are used.
•Do not use any screws other than what are installed on the instrument.

Optional AIEB2 or mLAN16E Installation
By installing an optional mLAN expansion board (mLAN16E) or an I/O expansion board (AIEB2), you can increase the input/output 
capability and interfacing options of the MOTIF ES. 
Installing the AIEB2
1Turn the power of the MOTIF ES off, and disconnect the 
AC power cord. Also, make sure to disconnect the 
MOTIF ES from any connected external devices. 
2Turn over the MOTIF ES so that the keyboard faces 
down, giving you direct access to the underside of the 
instrument.
To protect the Knobs, Wheels and Sliders from damage, 
place the keyboard so the four corners are supported by 
something that provides sufficient support like magazines 
or cushions.
Since the instrument — particularly the MOTIF ES8 — is very heavy, this 
procedure should not be done alone, but by two or three people.
3Remove the cover from the bottom. 
With the rear panel of the instrument facing you, remove the 
screws from the cover and slide the cover away to remove 
it. (The MOTIF ES6 and MOTIF ES7 have seven screws, 
while the MOTIF ES8 has five.)  On the MOTIF ES6/7, slide 
the cover away from you (toward the front of the instrument, 
as shown).  On the MOTIF ES8, slide the cover to the right.
Keep the removed screws in a safe place. They will be used when re-
attaching the cover to the instrument after installing the AIEB2.

Optional DIMM Installation
This section explains how to install DIMM memory modules to the MOTIF ES. 
Compatible DIMMs
The MOTIF ES does not necessarily support all commercially 
available DIMMs. Yamaha cannot guarantee operation of 
DIMMs that you purchase. Before purchasing DIMMs, please 
consult your Yamaha dealer, or an authorized Yamaha 
distributor (see list at end of the Owner’s Manual) for advice, 
or see the following page:
http://www.yamahasynth.com/
DIMM Type and DIMM Configuration
•Yamaha recommends that you purchase DIMMs that 
conform to the JEDEC* standard. Please be aware, 
however, that conformance to this standard does not 
constitute a guarantee that the DIMMs will operate correctly 
on the MOTIF ES. 
*JEDEC (Joint Electron Device Engineering Council) sets standards for 
terminal configurations within electronic devices.
•Use only 168-pin DIMMs of 64, 128 or 256 MB capacity 
(synchronized DRAM; PC100 or PC133).
•When installing DIMMs, make sure to install them in a 
matched pair of the same capacity.  You cannot install only 
one module and leave the second memory socket open.  
Also make sure each DIMM in the pair is of the same 
manufacturer and the same type. DIMMs of different 
makers and configurations may not work together.
•When purchasing DIMMs, make sure that the DIMM design 
does not utilize more than 18 memory chips per module. 
(DIMMs comprised of more than 18 chips do not operate 
correctly on the MOTIF ES.)
DIMM Installation
1~3
Use the same operation as in “Installing the AIEB2.” 
4Insert the two DIMMs into the DIMM sockets. 
5Re-install the cover you removed in step #3, in reverse 
order (page 285). 
6Check that the installed DIMMs are functioning properly. 
Set the MOTIF ES right-side up, and connect the power 
cord to the rear-panel AC INLET jack and an AC outlet. Turn 
on the power, go to the SAMPLING display by pressing the 
[INTEGRATED SAMPLING] button, and press the 
[INFORMATION] button (page 276). If the DIMMs have 
been installed properly, the appropriate available memory 
size is indicated in the display.
nIf the DIMMs have not been installed properly, the MOTIF ES may 
freeze when you press the [INTEGRATED SAMPLING] button. If 
this occurs, turn the power off, perform the instructions above 
again, and make sure to install the DIMMs firmly in step #4.

Glossary
This section explains in detail various words and terms that were not covered in the manual.  Another resource for looking up 
unfamiliar technical terms related to music, synthesis and audio is a special website we’ve prepared, the Glossary for Electronic 
Musical Instruments.  If you come across a musical or technical term you don’t know, click on the following URL.
■ Glossary for Electronic Musical Instruments 
http://www2.yamaha.co.jp/manual/english/word/index.html   (This URL and title may be changed without notice.)
A
Audition
The function or process of hearing the edited sample (in the 
Sampling function).
C
Channel
There are two types of channels: MIDI channels, which are used to 
transmit MIDI messages, and audio channels, which are used to 
send audio signals. You can set the MIDI channel in the display of the 
MOTIF ES. 
Clock
[1]A unit of note resolution for MIDI Sequence data. 
The sequencer determines the playback position of the Song or 
Pattern (MIDI sequence data) by using the units Measure, Beat, 
and Clock. 
[2]Also referred to as “MIDI Clock” or “Timing Clock” defined as 
System Realtime Message in MIDI. 
This message is transmitted at a fixed interval (24 times per 1/4 
note) to synchronize connected MIDI instruments. 
On the MOTIF ES, the Utility mode lets you select whether the 
instrument’s internal clock will be used as the Timing Clock, or 
external Timing Clock messages received via MIDI IN will be 
used.
Common
This edit related term refers to the editing of parameters that affect all 
Elements or Parts of a program. For each program, this term is used 
as listed below.
•Normal Voice .................Common Edit and Element Edit
•Plug-in Voice .................Common Edit and Element Edit
•Drum Voice....................Common Edit and Key Edit
•Performance .................Common Edit and Part Edit
•Song Mixing ..................Common Edit and Part Edit
•Pattern Mixing  ..............Common Edit and Part Edit
•Master ...........................Common Edit and Zone Edit
D
Destination
The MOTIF ES provides the following three types of destination. 
[1]In copy operations, this refers to the location to which the original 
“source” data or file is to be copied.
[2]In sampling operations, this refers to the internal memory area to 
which the external audio “source” is to be recorded.
[3]In the Controller Set function, this refers to the parameter adjusted 
by the controller defined as “Source.”
Directory
This is a path created on a data storage device (such as SmartMedia 
card or hard disk), allowing a tree-like hierarchical organization of data 
files and folders.  Effectively a virtual file cabinet, this is the place 
where files are stored and arranged according to type or application.
F
Filter
The MOTIF ES provides the following three types of Filter. 
[1]A circuit or processor that modifies tone by blocking or passing a 
specific frequency range of the sound. This is one of the Voice 
parameters (page 161).
[2]A function (referred to as “Event View Filter”) that lets you select 
the event types that appear on the Event List display in the Song 
Edit/Pattern Edit display (page 225). 
[3]
A function (referred to as “MIDI Filter”) that determines which MIDI 
events will be transmitted/recognized via the MIDI IN/OUT (page 262).
Folder
This is an organizational feature on a data storage device (such as 
SmartMedia card or hard disk), allowing you to group data files 
together according to type or application.  Folders can be nested in 
hierarchical order for organizing data.  (Also see “Directory.”)
L
LSB
[1]An abbreviation for Least Significant Byte, referring to the lower byte of 
data when MIDI control change data (such as Bank Select and Data 
Entry) is divided into two bytes (the MSB and LSB) for transmission. 
[2]An abbreviation for Least Significant Bit, referring to the lowest bit 
among eight bits that make up one byte.
M
MSB
[1]An abbreviation for Most Significant Byte, referring to the upper byte of 
data when MIDI control change data (such as Bank Select and Data 
Entry) is divided into two bytes (the MSB and LSB) for transmission. 
[2]An abbreviation for Most Significant Bit, referring to the uppermost 
bit among the eight bits that make up one byte. In MIDI, this “bit” 
is very important because it determines whether the byte to which 
this “bit” belongs is a status byte or data byte.
O
Offset
A type of editing in which a specified value (the “offset”) is added to 
or subtracted from the current parameter value. Unlike normal 
editing, in which the parameter is given a specific, new value, offset 
editing changes the parameter relative to its current value.
