About the Velocity Control Function
The MX-200’s organ tones play at a set volume level, regardless of how forcefully the keys are pressed
(Velocity Control: OFF). This is the setting for normal use.
Switching the Velocity Control function on allows you to adjust the volume level so to obtain a balance in
volume between the organ’s own tones and the MX-200’s organ tones*.
* Tones in the Classic Organ Category (FLUE, REED, MIXTURE, CELESTE, PEDAL, THEATER, ENSEMBLE)
and E.ORGAN Category.
This function applies velocity (which changes the volume in response to the force used to press the keys)
to tones that are not natively velocity-responsive. Use of this function allows you to adjust the volume of
the selected tone using the Rodgers organ coupler function (Velocity Level).
Turning the MX-200’s Velocity Control On and Off
1. Hold down the [VOLUME] knob and press the [VALUE] knob to enter Edit mode.
The “EDIT” MODE indicator lights.
2. Turn the [TONE CATEGORY] knob to select “CELESTE (SETUP MODE).”
The “SETUP” MODE indicator lights.
3. Turn the [PART] knob to select “10 (VELOCITY CONTROL).”
4. Turn the [VALUE] knob to select “ON.”
5. Press the [VALUE] knob to set (write) the value.
6. Press the [VOLUME] knob to exit Edit mode.
Adjusting the Organ Velocity Level
The following is a description of this procedure using the Rodgers Model 795 organ. The procedure used
for other models is roughly the same.
Before you start, you will need to make the required MIDI coupler settings.
1. Hold down the organ’s [SET] piston and turn the [SELECT] knob to the right to display the following
screen.
2. Turn the organ’s [SELECT] knob to move the cursor to “VEL.”
3. Turn the organ’s dial to adjust the volume.
The value set here (2–127) is transmitted to the MX-200 as the fixed velocity value used while performing.
4. Press the organ’s CANCEL (0) piston to quit the setting.
As this procedure sets the volume at a fixed, constant level, regardless of the force used in
pressing the keys, the level of expressiveness in the sound is more controlled. Use this
function only when you find you cannot achieve a proper tone balance while performing.

IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT
SAFELY” on page 2, please read and observe the
following:
Power Supply
301
• Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
302
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
307
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
Placement
351
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of inter-
ference.
352a
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
352b
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or initi-
ating a call, or while conversing. Should you experience
such problems, you should relocate such wireless devices
so they are at a greater distance from this unit, or switch
them off.
354b
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Also, do not allow lighting devices that normally are used
while their light source is very close to the unit (such as a
piano light), or powerful spotlights to shine upon the
same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.
355b
• When moved from one location to another where the
temperature and/or humidity is very different, water
droplets (condensation) may form inside the unit. Damage
or malfunction may result if you attempt to use the unit in
this condition. Therefore, before using the unit, you must
allow it to stand for several hours, until the condensation
has completely evaporated.
356
• Do not allow rubber, vinyl, or similar materials to remain
on the unit for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
359
•Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.
401b
• To clean the unit, use a dry, soft cloth; or one that is
slightly dampened. Try to wipe the entire surface using an
equal amount of strength, moving the cloth along with the
grain of the wood. Rubbing too hard in the same area can
damage the finish.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Repairs and Data
452
• Please be aware that all data contained in the unit’s
memory may be lost when the unit is sent for repairs.
Important data should always be backed up in another
MIDI device (e.g., a sequencer), or written down on paper
(when possible). During repairs, due care is taken to avoid
the loss of data. However, in certain cases (such as when
circuitry related to memory itself is out of order), we
regret that it may not be possible to restore the data, and
Roland assumes no liability concerning such loss of data.
Additional Precautions
551
• Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend that
you periodically save a backup copy of important data
you have stored in the unit’s memory in another MIDI
device (e.g., a sequencer).
552
•Unfortunately, it may be impossible to restore the contents
of data that was stored in the unit’s memory once it has
been lost. Roland Corporation assumes no liability
concerning such loss of data.
553
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
554
• Never strike or apply strong pressure to the display.
556
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
558a
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.

General MIDI is a set of recommendations that
standardizes the MIDI capabilities of sound modules.
Sound modules and music files that adhere to the
General MIDI standard bear the General MIDI logo
(). Music files bearing the General MIDI logo can be
played back using any General MIDI sound module with
essentially the same musical results.
The upwardly compatible General MIDI 2 ( )
recommendations pick up where General MIDI leaves
off, offering enhanced expressive capabilities and even
greater compatibility.
Issues not covered by the original General MIDI
standard - such as how sounds are to be edited, and how
effects should be handled - are precisely defined in
General MIDI 2. Moreover, the available sounds have
been expanded. General MIDI 2 compliant sound
modules are capable of reliably playing back music files
that carry either the General MIDI or General MIDI 2
logo. In some cases, the conventional form of General
MIDI, which does not include the new enhancements, is
referred to as “General MIDI 1” as a way of
distinguishing it from General MIDI 2.

Basic Operation
Playing the MX-200’s Sounds from the Organ
Now try out some of the MX-200’s various tones using the
MIDI couplers.
The following describes an example using the organ’s Great
keyboard.
■Try Playing Sounds from the
Organ
Make sure that the equipment is properly connected (p. 18)
and that the necessary settings are made (p. 22).
1. Turn on one of the organ’s MIDI couplers
(example: GT A).
When you play the keyboard to which the selected MIDI
coupler (example: GT A) is associated, sounds are then
played from the MX-200.
2. Turn the organ’s MIDI coupler off.
When the coupler is off, the MX-200’s sounds are not used
for the organ performance.
Organs are equipped with separate MIDI couplers for each
part. For example, the drawknobs, tablets, and pistons
labelled as “ORCH/MIDI GREAT,” “MIDI SWELL” and so
on are MIDI couplers. In addition, some organ models may
feature two MIDI couplers for one part, for example MIDI
GT A and MIDI GT B. In such cases, the MX-200 is capable of
playing the two tones A and B from a single keyboard.
What Are MIDI Couplers?
The MIDI couplers featured on Rodgers organs are couplers that allow the use of external sound modules. These
couplers are switches whose function is to “couple” or connect the organ with external sound modules.
Each MIDI coupler has a different MIDI channel pre-assigned to it. When a MIDI coupler is switched on,
performance data is output to that coupler’s MIDI channel. Connecting an external sound generator or module to
this MIDI channel further allows you to incorporate tones other than those of the organ in your organ performances.
Each keyboard on Rodgers organs is equipped with one or two of these MIDI couplers, thus totaling three to eight
MIDI couplers for the entire instrument.
The following table shows the correspondence between MIDI couplers and MIDI channels for the main Rodgers
organ models (current as of 2003).
GT: Great SW: Swell PD: Pedal CH: Choir SO: Solo
Shown in parentheses are the MIDI channels over which the keyboard data is output. These are used mainly in
recording performances with sequencers and other such devices.
Example:
If you are using a T797 organ, the MX-200’s Part 1 is played when the MIDI GT A piston is on.
With Rodgers organs, MIDI Channels 12–16 are used to output the performance data from the organ itself.
To prevent the MX-200 from playing the sounds on these channels, mute the corresponding parts (12–16) on the MX-
200 (p. 23). Note that if the corresponding parts are not muted, the sounds may still be played, even if you press the
organ’s Cancel (0) piston.

Basic Operation
Switching Tones with the
MX-200
Now try using the MX-200 to switch the MIDI coupler tones.
fig.
1. Set the MX-200’s [PART] knob to “1.”
2. Use the organ controls to switch on the MIDI GT
A (or GT) piston.
3. Select the desired tone category with the MX-
200’s [TONE CATEGORY] knob.
4. Turn the MX-200’s [VALUE] knob to select a
sound variation.
You can now perform with the selected tone when you
play the Great keyboard.
In the same manner, you can set other tones for the other
keyboards using the corresponding part numbers, for
example assigning tones to the Swell keyboard with Part 2,
the Pedalboard with Part 3, assigning part numbers to the
Choir keyboard and coupler B as well.
* You can save the settings that determine which tone is used
with each of the organ’s MIDI couplers. When tones are
selected by operating the MX-200, the saved tone selections
are cancelled as the result of such selections.
* For instructions on how to save tones to the organ’s MIDI
couplers, refer to your organ owner’s manual.
Adjusting the Master tuning
on the MX-200
When adjusting the organ’s tuning, the MX-200’s tuning
must also be changed to the same value. Matching the tuning
removes muddiness in the sound, allowing you to get a
clearer, more beautiful sound.
1. Press the [VALUE] knob to make the TUNE
indicator in the display lights up.
2. Turn the [VALUE] knob to adjust the tuning.
The frequency of A4 is used as the basic reference pitch.
When indicating this frequency, the display shows the
lowest two digits and the first digit after the decimal
point.
For example, when set to 440 Hz, “40.0” is indicated in
the display.

Basic Operation
Selecting Temperament on
the MX-200
The “temperament” specifies the intervals between the keys.
Adjusting the pitches of the instrument based on this is
referred to as “tuning.”
With the MX-200, you can select from eight different
temperaments: Equal, Mean-Tone, Pythagorean, Kirnberger,
Werckmeister I, Werckmeister III, Young I, and Young II.
1. Press the [VALUE] knob to make the TUNE
indicator in the display lights up.
2. Turn the [TONE CATEGORY] knob to adjust the
temperament.
The correspondence between the position of the TONE
CATEGORY knob and the temperament is as shown
below.
fig.Category
Equal
Also known as 12-Tone Equal Temperament. Now the most
commonly used temperament, it makes performances sound
the same in any key. Most musical works after the Roman
period were composed under the assumption that they
would be performed in Equal temperament, and this
temperament is used today for almost all keyboard
instruments.
Mean-Tone
Mean-Tone is an unequal temperament that was created by
partially modifying the Just temperament to allow
modulation. In modulations up to three sharps or two flats,
chords sound very similar to chords in Just temperaments.
Pythagorean
This was developed by the Greek philosopher Pythagoras.
This scale eliminates the lack of definition in fourths and
fifths. While it does yield beautiful-sounding melodies, it
also creates ambiguity in the thirds. Passed down by the
Greeks to the Romans, it was used for a long period in
church music as the scale for the Gregorian chants. In fact, it
was the main tuning used up until the development of the
Mean-Tone temperament.
Kirnberger
This tuning is an improvement of Mean-Tone and Equal
temperaments. Along with the Werckmeister temperament,
it is often used in concerts and recitals.
Werckmeister I and III
This temperament, which exhibits greater freedom of
modulation than the Mean-Tone temperament, was devised
to sound harmonically in key signatures with few incidentals
and melodically in key signatures with more incidentals.
Young I and II
A classical temperament devised by Vallotti around 1754,
later improved on by Young. This has become the basis for a
variety of different tunings.
Once you set the temperament, it does not change until you
use the procedure to switch the temperament again. Even
when the [TONE CATEGORY] knob is adjusted for some
other function, the temperament still remains the same.
The temperament is reset to Equal when the power is turned
off.
Switching the Reverb Type
Reverb refers to the reverberation that normally occurs
within a room. Applying reverb lets you add more richness
to the sound being output. The lower the type number you
select, the less reverb is added to the sound; higher numbers
result in a grand, majestic-sounding reverberation. Pipe
organs in particular are used in large churches that feature
long reverberation times, and adding reverb allows you to
reproduce this imposing sound.
Certain large organ models allow reverb to be applied to the
sounds from a connected MX-200. In such instances, you may
find it better not to add much reverb to the MX-200’s sounds.
1. Press the [VALUE] knob so that the TUNE
indicator lights in the display.
2. Turn the [PART] knob to select the reverb type.
You can select one reverb type to be applied to the MX-200’s
overall sound.
You can adjust the amount of reverb for each part
individually with the Part Reverb Send Level (p. 23) in Edit
mode.

Advanced Ways to use
Switching Tones with MIDI
Besides switching tones directly with the MX-200, you can
also switch the MX-200’s tones using MIDI. Rodgers organs
are designed to take advantage of this function.
The following describes two ways to switch tones using
MIDI.
Tone Map
The tones contained in the MX-200 can be selected with the
numbers indicated in the tone map by means of Program
Change (PC), Bank Select (MSB), and Bank Select (LSB).
MIDI signals are designed to enable the communication of
performance data among sixteen separate sound modules.
With the MX-200, these sixteen sound modules correspond to
the part numbers 1 through 16, and you can select the tone
for each individual part by setting the PC, MSB, and LSB for
the respective part.
For instructions on how to do this, refer to “Selecting Tones
from the Organ” in the column to the right.
(Examples) Selected from the Tone List (p. 28)
When “93” is received for the MSB, “126” for the LSB, and
“3” for the PC, the tone “16' Pommer” is selected.
* The MX-200’s display may not show any particular changes
when tones are changed with MIDI. However, since changes
are handled in exactly the same manner whether made with the
panel controls or with MIDI, when a PC is received following
adjustments with the panel controls, the tone selected with the
panel controls is switched to the tone received via MIDI.
Conversely, when a tone is switched with the panel controls
after tones have been switched with MIDI, the tone selected via
MIDI is switched to the tone selected with the panel controls.
Selecting Tones from the
Organ
Using signals called MIDI Program Changes, the MX-200
allows you to switch its tones without directly operating the
unit. You can store these Program Changes to the organ’s
MIDI couplers to switch the MX-200’s tones.
By way of example, the following will set the Rodgers T797
organ’s GT A MIDI coupler to “002: MX Strings” in the MX-
200’s STRINGS category. To select the “MX Strings” tone,
you will need to set PC: 113, MSB: 93, and LSB: 126
(alternatively, you can select this with PC: 50, MSB: 65, and
LSB: 0). (See Tone List (p. 28).)
→Also refer to “Connecting to MIDI Devices” in the T797
Owner’s Manual. If you happen to be using a different model
Rodgers organ, similar descriptions will be given in the
Owner’s Manual for that model.
1. Hold down the organ’s [SET] piston and press the
MIDI coupler piston for the part to be used (in
this case, press GT A).
The MIDI coupler piston flashes, indicating that the
instrument can be set.
2. Turn the organ’s [SELECT] knob to highlight the
PGM number.
3. Rotate the organ’s Alpha Dial to select the
Program Change number (113) you want to have
transmitted.
4. Turn the organ’s [SELECT] knob to the MSB
number.
5. Rotate the organ’s Alpha Dial to select the Bank
Select MSB number (93) you want to have
transmitted.
6. Turn the organ’s [SELECT] knob to the LSB
number.
7. Rotate the organ’s Alpha Dial to select the Bank
Select LSB number (126) you want to have
transmitted.
8. Press the GT A coupler piston.
It stops flashing. You can now play “MX Strings” tone on
the Great manual.
→For more detailed information on Program Change numbers
and Bank Select MSB and LSB numbers, refer to the Tone
List (p. 28).
The procedure above assigns “002: MX Strings” from the
MX-200’s STRINGS category to GT A MIDI.
Save the MIDI coupler settings to the organ’s combination
piston. If you press the combination piston without first
saving the MIDI coupler settings, the current settings will be
cleared.

Advanced Ways to use
Switching Tones from the
Organ Keyboard
Rodgers organs feature a “Quick Key Map” function that lets
the performer use the organ keyboard to switch the tones.
This function allows you to switch the MIDI coupler tones
simply and easily as you perform, without having to adjust
the MX-200 itself.
When switching tones, the only numbers that can be
specified from the keyboard are the “PC” numbers. The MSB
and LSB numbers must be set ahead of time. Following the
instructions in the organ Owner’s Manual, set the MSB to 65
and the LSB to 0. Setting the MSB to 65 selects the “Capital
Tone” as the basic tone to be used. To select other variations,
set MSB numbers from 66 to 69.
Instructions for Setting the MSB/LSB
(Overview)
1. Hold down the SET piston and turn the SELECT
knob to switch to the MIDI coupler settings
screen.
2. Turn the SELECT knob to advance to the PGM/
MSB/LSB menus.
* Some earlier model organs have no LSB displayed, and show
VAR instead of MSB. However, as the LSB is set to 0 anyway,
this presents no problem.
3. Set MSB to 65 and LSB to 0. Select a number for
the PGM as well so that OFF no longer appears in
the display.
How to Switch Tones Using the Quick
Key Map
1. Hold down the (SET) piston and press the desired
MIDI coupler.
The MIDI coupler lamp flashes, and the selected tone is
enabled.
2. Play a key on the keyboard.
The tone is switched, without the note for that key being
played, and the MIDI coupler lamp stops flashing and
remains lit.
To view the key map itself, see p. 44.
* When using a device that has the MIDI couplers assigned to
tablets, press the upper tablet area instead of the MIDI
couplers.
* Note that certain organ models do not feature a tone selection
mode.
Part Mute
In addition to the MIDI coupler tones, performance data
from the organ itself is transmitted via specific MIDI
channels. Most Rodgers organs use Channel 12 through
Channel 16 (Parts 12 through 16) for this purpose. The MX-
200 features a “Part Mute” function to deal with this data.
For instructions on making the Part Mute settings, refer to
Part Mute (p. 23).
Rhythm Sets
Performance data received over Channel 10 (Part 10)
contains particular tone arrangements called “rhythm sets.”
You can use a “rhythm set” in any part by selecting “rhy” for
the part type (on p. 23).
For instructions on making the actual settings, refer to Part
Type (p. 23).
Tremulant Effect
Tremulant is an effect that adds a trembling effect to the
sound.
While this effect is generally known as “vibrato,” with pipe
organs, this particular effect is obtained through the use of
special boxes that change the air pressure.
With the MX-200, tones in the Tone List (p. 28) appended
with (*1) are linked with the organ, so the tremulant effect
will be automatically applied when the tremulant is switched
on by means of the organ’s controls.
* If the organ features two MIDI output systems, the MX-200
must be connected with the organ’s Sequencer Out.
* The organ must be set so that the tremulant is included in the
stops.
However, some tones already have the tremulant applied.
(Example)
The FLUE #011 tone is the FLUE #004 tone with tremulant
added.
Quick Key Map Mode
In selecting tones with the keyboard as described above,
if the (SET) piston is held down and one of the keys on
the keyboard is pressed, the unit switches to Quick Key
Map mode, and the MIDI coupler continues to flash.
You can perform as usual in this mode, but you can also
change tones by holding down the (SET) piston and
pressing a key on the keyboard.

15
Advanced Ways to use
Using SRX Wave Expansion
Boards
The MX-200 is equipped with one “slot,” which accepts a
Roland SRX Series Wave Expansion Board. Installing a Wave
Expansion Board allows you to increase the number of MX-
200 tones you can use.
The Wave Expansion Board can be installed by removing the
top cover.
A wave board designed exclusively for use with the MX-200
comes installed in Slot B. Do not remove this board.
Removing this board will prevent the MX-200 from
functioning correctly.
■Cautions When Installing an
Wave Expansion Board
• To avoid the risk of damage to internal components that
can be caused by static electricity, please carefully
observe the following whenever you handle the board.
→Before you touch the board, always first grasp a
metal object (such as a water pipe), so you are sure
that any static electricity you might have been
carrying has been discharged.
→When handling the board, grasp it only by its edges.
Avoid touching any of the electronic components or
connectors.
→Save the bag in which the board was originally
shipped, and put the board back into it whenever
you need to store or transport it.
• Do not touch any of the printed circuit pathways or
connection terminals.
• Never use excessive force when installing a circuit
board. If it doesn’t fit properly on the first attempt,
remove the board and try again.
• When circuit board installation is complete, double-
check your work.
• Install only the specified board, and remove only the
specified screws.
• Be careful not to cut your hands on the opening for
installing the board.
■How to Install a Wave
Expansion Board
1. Before installing the Wave Expansion Board,
switch off the power to the MX-200 and any
connected equipment.
2. Detach the cover on the upper portion of the MX-
200. Loosen the screw on the upper portion of the
cover.
fig.Exp1.e
3. Position the board holders so they are oriented.
fig.Exp2
4. Insert the connector for the Wave Expansion
Board into the connector on the unit, and at the
same time, fit the board holders into the holes.
fig.Exp3.e
5. Use the tool supplied with the Wave Expansion
Board to rotate the board holders to LOCK,
securing the Wave Expansion Board in place.
fig.Exp4
6. Use the (specified) screws you removed in step 2
to reattach the cover.
This completes the installation of the Wave Expansion Board.
Next, make sure the board is installed correctly (p. 16).

the last two digits of the Wave Expansion Board’s model name
are displayed.
For example, If you have an SRX-01 “Dynamic Drum Kits”
installed, “A01” will be displayed.
3. Turn [TONE CATEGORY] to choose EXP.
fig.Exp6
If 001 appears in the display, the Wave Expansion Board has
been installed correctly.
If the display shows “- - -,” it’s likely that the Wave
Expansion Board is not being recognized correctly. Follow
the steps inTurning Off the Power (p. 9) to switch off the
power, then reinstall the Wave Expansion Board, making
sure you do it correctly.
Using a Sequencer
Playback
When data prescribing the tone selections has been placed at
the beginning of a song, the song is played using the tones
the song data prescribes, regardless of the MX-200’s settings.
If no data prescribing the tone selections has been recorded
at the beginning of a song, the song is played in accord with
the MX-200’s settings.
In addition, when GS or GM song data is played back, the
MX-200 functions as a GS/GM sound module.
The MX-200 may not function as a GS/GM sound module
when RECEIVE GM2 ON (p. 25) is set to OFF.
Recording
The arrangement by which the data for selecting tones is
recorded at the beginning of the song data is handled by the
organ and sequencer. When the sequencer is placed in record
mode, it transmits a message alerting the organ that it is
ready for recording. In response to this, the organ transmits
information regarding the tones selected on the organ itself
and the MIDI coupler tone selection data. The sequencer
records this information while further transmitting the tone
selection data to the MX-200. In this manner, the sequencer
records the tone selection data at the beginning of the song
data.
The MX-200 is designed to be used in conjunction with the
MR-200 sequencer, which performs the operation described
above automatically. When using other sequencers with the
MX-200, refer to the corresponding MIDI Implementation for
the proper settings.
