About DX-XG
The DX Extension for XG (“DX Extension for XG” is abbreviated to DX-XG) included in the
PLG100-DX significantly enhances and expands the musical capabilities of the XG format with
the superior sound and expressive potential of Yamaha FM synthesis. The PLG100-DX supports
the same powerful FM synthesis voices as Yamaha’s legendary DX7. Plug this board into your
tone generator/sound card for 912 unbelievable FM voices with up to 16-note polyphony.

About the PLG100-DX
Features of the PLG100-DX
• Features the same FM tone generator that has won acclaim in the DX
series synthesizers.
The PLG100-DX employs an FM tone generator system, with six operators and 32
algorithms, that has been a favorite of musicians in DX series synthesizers like the
DX7 and the DX7II.
• Maximum 16 voice simultaneous polyphony
Ensures maximum 16 voice simultaneous polyphony equal to the DX7 and DX7II.
Furthermore, by installing multiple PLG100-DX boards, the maximum polyphony can
be increased to 128 voices (when eight boards are installed). By installing, for example, three PLG100-DX boards in the MU128 tone generator, maximum polyphony
will be 48 voices.
• 912 preset voices
The PLG100-DX already has 912 preset voices built right in. From electric piano to
bass, and reaching all the way to effect sounds, the preset voices have been selected for
usability centering on the sounds that made the DX series famous.
• Voice data can be exchanged in bulk between the DX7 and the DX7II
Because the PLG100-DX is compatible with the DX series, it can be used for bulk
transfer of voice parameters between the DX7 and the DX7I I. The DX7 and DX7II can
be used as editors for the PLG100-DX. By using the edit software for the DX7 and the
DX7I I, editing can be done for the PLG100-DX. Voice parameters for the DX1, DX7S,
TF1 (such as the TX816) TX7 and the TX802 are also supported.
• Some voices may sound slightly different than the voices of the devices mentioned above.
• Comes equipped with a low pass filter, a high pass filter and a two-band
equalizer.
A low pass filter, a high pass filter and a two-band equalizer have been installed in the
PLG100-DX. These features can be used together with the voice editing parameters for
the FM tone generator to create new voices. Even if you install the PLG100-DX in a
platform that doesn’t have these functions, the filters and EQ built into the PLG100DX will work.
• Compatible with the XG Plug-In system
Because the PLG100-DX is an XG plug-in board, it can be installed in any XG plug-in
tone generator, like the MU128.
Installing the PLG100-DX
To install your PLG100-DX board, see the manual that came with the “mother” tone generator (such as the MU128 or SW1000XG) or synthesizer.

Necessary Items that Are Not Included
XG tone generator or synthesizer
To use your PLG100-DX, you will need an XG tone generator or synthesizer equipped
with an XG Plug-in platform function that is compatible with the XG Plug-in system,
such as the MU128 or SW1000XG.
About the PLG100-DX
The MU128 and SW1000XG are equipped with each of the XG Plug-in platform functions, and can be used for installing the PLG100-DX.
The software programs explained below will put the functions of the PLG100-DX right
at your fingertips, helping you get the most enjoyment out of it.
XGworks(lite)
When you use Yamaha’s XGworks(lite) as your sequence software, you can take advantage of the two editing software programs explained below, the “DX Simulator”
and the “DX Easy Editor.” These programs make it really easy to edit the voices of
your PLG100-DX board.
DX Easy Editor
The DX Easy Editor lets you indirectly change the PLG100-DX voices by changing the
part parameters. It’s not for directly editing the voice parameters. Using this software,
you can edit both the XG part parameters (XG parameters) that are shared by all the
parts, and the native part parameters that are specially for the PLG100-DX (DX parameters). The changed parameters can be either inserted into the song as events, or saved
as a DX parameter file.
Because the DX Easy Editor is plug-in software for XGworks(lite), you must have
XGworks(lite) in order to use it.
The DX Easy Editor is included on the CD-ROM that was packaged with your PLG100DX board.

About the PLG100-DX
DX Simulator
The DX Simulator is special software for editing the custom voices of the PLG100DX. When you start up the program, an image of the DX7 front panel is displayed on
your computer screen. Using your mouse to operate the buttons and sliders, you can
edit voices just like using a real DX7. You can also display an edit list where you can
edit voices while checking all the parameters in a table on the screen. The edited voice
data can be either saved in memory or to a file, or can be inserted into a track as bulk
data.
Because the DX Simulator is plug-in software for XGworks(lite), you must have

About the CD-ROM
In addition to the two plug-in software programs, DX Simulator and DX Easy Editor, the
CD-ROM that was packaged with your board also contains several demonstration songs
that showcase the special features of the PLG100-DX, and also performance data (voice
settings) for use in the platform where you have installed your PLG100-DX. The demonstration songs can be enjoyed by playing them with sequence software like XGworks
V2.0 or XGworks(lite), or with a QY700. (A platform for connecting the PLG100-DX is
also necessary.) Use the same sequence software or device to send the performance data
as bulk data to the platform for the PLG100-DX.
● Demonstration Songs
“Ie Kia Bara Hein” (IeKiaBar.MID) by Noritaka Ubukata (Shofuku)
The title of the song means “What kind of spell is this?” in the Hindi language. It
features the voice that simulates a santur (hammer dulcimer) together with a sitar.
About the PLG100-DX
“DX VOICE” (DXVoice.MID) by Noritaka Ubukata (Shofuku)
Starting with the electric piano, this song features a series of the sounds of DX7
Shofuku. Unlike sampling, this music offers the listener subtle variation in the sound
caused by changes in velocity. Another special feature is the FM choir, where a more
realistic sound is created by combining FM synthesis with sampled human voices.
“Vel&EffectWorks1” (V1_EfWk1.MID)
“Vel&EffectWorks2” (V1_EfWk2.MID)
“DX Short Demo” (DxShtDM.MID) by Yasuhiko Fukuda (Shofuku)
These songs showcase a unique feature of FM: the violent changes in sound that are
caused by velocity.
“80’s Pops” (80Pop.MID) by Katsumi Nagae (Idecs Inc.)
Recalls the pop scene of the 80’s with synpads and metallic sounds like dum bells.
“D-Rock” (D-Rock.MID) by Katsumi Nagae (Idecs Inc.)
This song brings back the digital rock sound using the noise and SE system voices
that only DX has.
If you want to use digital noise, there is nothing that works like DX!
“EP Ballade” (EP.MID) by Katsumi Nagae (Idecs Inc.)
If it’s ballads you want—well, there is nothing like DX electric piano.
The voice in the electric piano part will also work with different electric pianos. Try
playing the song with different piano voices.

About the PLG100-DX
“House” (HOUSE.MID) by Katsumi Nagae (Idecs Inc.)
The typical house music sound is simulated in this song, which experiments with
reproducing sampling phrases using the DX Voice system. In addition, the second
half of the song features the metalic sound that is a strong point of the DX.
“Jungle” (DXJungle.MID) by Katsumi Nagae (Idecs Inc.)
This song adds a touch of Chinese feeling to the Jungle. The Oriental image is underscored by the “CHINA_S&” and “IMAGE9” plug-in SE voices.
If no sounds are played, or if you experience other problems with playback, see Appendix “When Your PLG100-DX Seems to Have a Problem” (→P. 59).

FM Tone Generation
Before actually editing the PLG100-DX voices, let’s get an idea of how the FM tone generator is
put together.
Operators
In the PLG100-DX, there are six special devices called “operators” that generate sine
waves. These six operators are combined in various ways to make up the different voices
produced by the PLG100-DX. The operators have the following two functions:
(1) They can freely change the frequency (pitch) of the generated sine wave.
(2) They can freely change the amplitude (volume or output level) of the generated
sine wave.
A sine wave is the fundamental wave of a note, with absolutely no overtones added.

Combinations of Two Operators
Although the six operators can be combined in myriad ways, here the fundamental combinations that involve two operators will be explained.
Two operators can be combined in the following two ways (the two operators will be
called A and B respectively):
(1) Horizontal Combination
When the two operators are combined horizontally, the sound generated by each is mixed
with the sound from the other. The actual sound (sine wave) is produced by A and B acting
together.
FM Tone Generation
A B
Mixed sound of A and B
The actual sound is generated by
A and B together
(2) Vertical Combination
When the two operators are combined vertically, the upper operator B works to change the
sound of the lower operator A, and a complex waveform with many overtones added to it
will be the output from operator A. In this situation, the B operator serves only to change
the sound of operator A, and does not generate the actual sound. Operator A generates the
actual sound as it undergoes changes caused by B. When the upper operator works to
change the sound of the lower operator in this way, it is called FM modulation (or simply
modulation).
B
B changes the sound of A (it generates no tone).
While A undergoes changes caused by B, it generates
A
the actual sound.
When these are put together, it looks like this:
• Horizontal Combination The two operators both generate the sound.
• Vertical Combination One operator is for changing the sound of the other operator.
One operator is for making the sound.
When two operators are combined vertically in this way, they both work completely differently.
11
FM Tone Generation
Carrier and Modulator
To distinguish the two operators when they are combined vertically, they are called the
“Carrier” and the “Modulator.”
• Carrier ................. The operator in the lowest position, that produces the actual sound. (Called A
• Modulator ............ An operator positioned above another operator, which changes (modulates)
When there are three or more operators, each operator is classified as a carrier or modulator in the same way.

(1) When all the operators are combined horizontally, there is no modulator and they are
all carriers. Because there is no modulation, all waveforms generated by the carriers
are sine waves.
(2) When three operators are piled vertically, only the lowest operator is a carrier. The
modulator on the top modulates the lower modulator, and the modulated waveform
from the lower modulator in turn modulates the carrier. The modulation of the carrier
becomes deeper and the sound output has more overtones.
12
(3) Here there are two carriers and one modulator. The modulator modulates the carrier
immediately below it. The modulated carrier generates sound with overtones. The
other carrier produces a pure sine wave. Finally, the sound from the two carriers is
mixed to form the whole sound.
(4) Here there is one carrier and two modulators. The two modulators each independently
modulate the single carrier. Since the carrier is modulated by the two modulators, it
generates a sound that has more overtones.
(5) Here there are two sets of two operators that have been combined vertically. In each of
them, the modulator modulates the carrier immediately below it, and the carrier generates a sound that has overtones. Finally, the sound from the two carriers is mixed to
form the whole sound.
Harmonics
Most sounds are made up of multiple tones that are different than the pitch (frequency).
Within these multiple tones, the one that determines the pitch of the entire sound is called
the fundamental tone (fundamental frequency). All the tones besides the fundamental tone
are called partials or overtones.
When all the harmonics that are related to a particular fundamental tone are arranged in
order, it is called a harmonic series. Each tone in the harmonic series is given a name in
order, with the fundamental tone being one, followed by the second harmonic, third harmonic and so on.
The frequency of each harmonic in the harmonic series is a natural number multiple of the
frequency of the fundamental tone. Overtones that have frequencies that are not natural
number multiples of the fundamental are called unharmonic overtones.
Generally, the more harmonics the tone has, the brighter the sound. On the other hand, if
the amount of harmonics is reduced, the tone will sound darker. Furthermore, the voice
will change a lot according to the type and volume of the harmonics. For example, if there
are a lot of high pitched harmonics in the tone, it will have a brilliant, crisp sound. On the
other hand, a tone with a large amount of lower harmonics will have a rather massive,
dignified sound.

Algorithms
While there may be only two ways to combine two operators, when you start talking about
six operators, the number of possible combinations becomes much larger. These combinations of six operators are called “algorithms,” and in both the DX7 series and the PLG100DX, 32 of these combinations have been selected that can be used for creating voices.
In an FM tone generator, which operators work as carriers and which work as modulators
are changed dynamically by the algorithms. For this reason, the first thing you have to
know when editing a voice is which algorithm is used by that voice.
The algorithms are numbered from 1 to 32. For information about the 32 algorithms, see
“Appendix, Chart of Algorithms” (→P. 28).
The six operators have also been numbered from one to six to help in distinguishing them.
Let’s take algorithm 28 as an example. In this algorithm, the operators work as follows:
Operator 1 ............. Outputs sounds while being modulated by Operator 2 (Carrier).
Operator 2 ............. Modulates Operator 1 (Modulator).
Operator 3 ............. Outputs sounds while being modulated by Operator 4 (Carrier)
Operator 4 ............. Modulates Operator 3 while being modulated by Operator 5 (Modulator)
Operator 5 .............
Operator 6 ............. Outputs a sine wave (Carrier)
Modulates Operator 4 while being modulated with its own feedback (Modulator).
Feedback
Feedback is a function where a portion of the output of an operator is returned back to the
operator again, where it is used to modulate the operator itself. Using feedback results in a
deeper sound.
Every one of the 32 algorithms has feedback set in one location. Among them there is even
one algorithm, number 4, where the output of three operators as a group is used as feedback. When a portion of the output of operator 4 in this algorithm is returned to operator 6,
an extremely deep sound is obtained.

Essentials for Determining Voices
Voices are determined by the following main elements:
(1) The output level from each operator (OUTPUT LEVEL).
(2) The frequency of the tone put out by each operator
(OUTPUT FREQUENCY).
(3) The feedback level (FEEDBACK LEVEL).
(4) The Envelope Generator (EG).
Each of these will be explained in order.

Feedback
(1) The output level from each operator
When voices are edited, the most important point is the output level for each operator.
Among these, the output level of the modulator has the largest effect on the voice. For
example, when two operators are vertically combined, and the output level of modulator B
is set to zero, the output waveform of carrier A will be a simple sine wave (a dark tone with
no harmonics included). If the output level of the modulator is gradually increased from
this condition, the amount of modulation will become deeper and the output waveform
from the carrier will change to one with many harmonics in it. As the harmonics increase,
the tone will also become brighter, finally changing to a harsh, grating sound.
From this we can conclude that the degree of modulation, which equals the brightness of
the sound, changes in relation to the output level of the modulator.

FM Tone Generation
On the other hand, because the carrier actually makes the sound, changing the output level
causes a change in the strength (volume) of the sound. If there is only one carrier, this will
simply cause the overall volume to change. However, if there are multiple carriers in the
algorithm, the timbre may also be changed as the balance in volume between the different
carriers is changed.
To summarize these points:
• The voice changes according to the output level of the modulators.
• The volume changes according to the output level of the carriers. The voice may also be changed
as the balance in volume between multiple carriers changes.
(2) The Frequency of the Tone Output from Each Operator
The type of harmonics added to the carrier output by means of the modulator is determined
by the ratio between the frequencies of the modulator and carrier. For example, when two
operators are combined vertically, and “F COARSE” for both of them is set to 1.00, the
frequency ratio will be 1:1 and the first, second, third and following whole number series
harmonics will be generated in order. This type of harmonic configuration is called a
sawtooth wave, and is used for making voices like brass, strings, or piano.
If the “F COARSE” for the modulation in this situation is changed to 2.00, the frequency
ratio will be 1:2, and the odd numbered harmonics, the first, third and fifth and following
harmonics will be generated. This harmonic configuration is called a rectangular wave,
and is used for creating voices for woodwinds like the clarinet and oboe.
Furthermore, if “F FINE” is used so that the frequency ratio is not a whole number, many
non-integer overtones will be produced. The sound can be used for creating metallic sounds,
the noise when strings are hit with something, or breath noise.

(3) FEEDBACK LEVEL
By raising the feedback level, the modulation deepens, and the timbre of the sound becomes brighter.
(4) Envelope Generator (EG)
The EG creates the changes over time in the output level from the instant a key on the
keyboard is pressed to the time that the sound disappears.
If you listen to various musical instruments, you soon realize that besides the differences
in the timbre of the sounds they create, there is a large difference in the way that the sound
first comes out, and in the way in which it fades away. For example, the sound from a
piano gets very loud the instant a key is struck, then the volume gradually fades away, even
if you continue pressing down the key. Also, if you look at the change in tone over time,
there is a bright sound with a lot of overtones the moment the key is struck, but the overtones soon fade away, and the tone takes on a darker aspect.
The function that produces the instrument’s change in volume and timbre over time is the
EG.
In an FM tone generator, an EG is built into each operator. The EG for the carrier changes
its volume over time, while the EG for the modulator changes the timbre of the sound over
time.

(64 Voices)
Edit Recall
Edit Recall Buffer
• The only voices that can be edited using an editing program like the DX Simulator are the custom
voices.
When using the custom bank
• The following parameters are not valid when using the custom bank because they are saved as voice
parameters.
XG Native Part Parameters
MONO/POLY MODE
BEND PITCH CONTROL
PORTAMENTO SWITCH
PORTAMENTO TIME
PLG100-DX Native Part Parameters
PitchBend Step

Portamento Mode
However, MONO/POLY MODE, BEND PITCH CONTROL, PORTAMENTO SWITCH, and
PORTAMENTO TIME are received through CC (Control Change). (When changing to another custom bank voice, that voice will be set to the saved parameters.)
• If an XG System On is received, or part assignment is changed, the custom voices will be initialized, but
the 64 voice VMEM and AMEM areas will not be initialized.

DX Voice Selection
The PLG100-DX voices can be selected just like the voices for the XG tone generator itself.
However, to use the PLG100-DX voices, XG mode or performance mode (PERFORM) must be
selected in the Sound Module Mode of the XG tone generator. Also the part/performance layer
assigned to the PLG100-DX must be specified in the sub-mode (PLUGIN) of the utility mode of
the XG tone generator.
• The displays used below for explaining tone generator operations are from the MU100. The screens may be
different for the tone generator you are using.
• For tone generators, like the SW1000XG, that have no display, the settings must be sent as System Exclusive
Messages (→ MIDI Data Format).
• The SW1000XG does not support the Performance Mode.
■ Selecting the Voices to be Used .............................................................................
1. Set the Sound Module Mode of the XG tone generator to XG or PERFORM.
When XG is selected, the tone generator will enter Multi Mode.
When PERFORM is selected, the tone generator will enter Performance Play Mode.
• DX voices can be selected only when the Part Mode is set to Normal.
• In XG Mode, DX voices can be used as one part, and in Performance Mode, as one layer.
2. Press the [SELECT / ] buttons, and move the cursor to the bank number.
3. Press the [VALUE / ] buttons and select the bank of the voice you wish to use.
Depending on the bank you have selected, one of the following will appear in the bank
number location of the display: 000,064 to 082, 096 to 109 (DX-XG/A); 000,064 to
082 (DX-XG/B); 000 (DX-XG/SFX) or 000 (Custom).

Editing DX Part Parameters
Editing with the parameters below is valid for voices in all banks. However, they cannot be set
separately for each voice. This means that whatever editing changes you have made will be
transferred as is to the new voice whenever you switch voices (editing done for the previous
voice will be also valid for the next voice chosen).
• When voices are switched after the parameters have been changed, or when the algorithm is changed with the
DX Simulator, unexpected sounds may cause injury to your ears. Always exercise caution when making changes.
• Parameters that have been edited cannot be stored in custom voices.
• When using the DX Simulator, voices can be edited, then stored in custom voices.
1. In Multi Play Mode, choose the part assigned to the PLG100-DX, then select the voice
to be edited.
2. Press the [EDIT] button.
The Multipart edit menu screen will be displayed.
3. Press the [SELECT ] button and move the cursor to “PLUGIN”. Press the [EN-
TER] button.
The parameter screen for the selected plug-in board will be displayed.
4. Press the [SELECT / ] buttons to move the cursor to the parameter to be edited.
Next, change the value for the parameter using the [VALUE
/ ] buttons.
5. Press the [EXIT] button several times to return to the initial screen.
• On the MU100 panel, normal part parameters that can be edited will be valid for DX voices.

Editing DX Part Parameters
■ PLG100-DX Part Parameters ...................................................................................
Carrier1 (Carrier Operator 1 Level) to Carrier6 (Carrier Operator 6 Level)
Settings: -64 to +63
Explanation:
• Sets the output level for operators that are working as carriers.
• Carriers are operators that work to output the actual sound. Changing the carrier output
level changes the loudness of the sound that is produced. If an algorithm is selected that
has multiple carriers, the quality of the sound, or “timbre” can be edited by changing
the volume balance between the carriers.
• Because this setting acts as an offset added to the output level set for the voice in the
PLG100-DX, it indirectly changes the timbre of the voice. When this parameter is set at
zero, the voice will remain as is. Setting it to +1 or more will increase the volume, while
setting it to -1 or less will decrease it.
• The operators that are assigned as modulators will be displayed as “***”, and it will not
be possible to edit them. To clarify matters when editing voices, look up the algorithm
number for the voice being edited on the voice list, then check which operators have
been assigned as carriers on the Chart of Algorithms (→P. 28).
Modulator1 (Modulator Operator 1 Level) to Modulator6 (Modulator Operator 6 Level)
Settings: -64 to +63
Explanation:
• Sets the output level for operators that are working as modulators.
• Modulators are operators that serve to modulate other operators. Changing the modulator output level changes the brightness (amount of overtones) of the sound that is produced.
• Because this setting acts as an offset added to the output level set for the voice in the
PLG100-DX, it indirectly changes the timbre of the voice. When this parameter is set
to zero, the voice will remain as is. Setting it to +1 or more will make the sound brighter
(increase the overtones), while setting it to -1 or less will darken it (decrease the overtones).
• The operators that are assigned as carriers will be displayed as “***”, and it will not be
possible to edit them. To clarify matters when editing voices, look up the algorithm
number for the voice being edited on the voice list, then check which operators have
been assigned as modulators on the Chart of Algorithms (→P. 28).

Editing DX Part Parameters
FeedBack
Settings: -7 to +7
Explanation:
• Sets the level of feedback.
• Feedback is a function where a portion of the output of an operator is returned
back to the operator again, where it is used to modulate the operator itself. Feedback can be used to change the brightness (amount of overtones) of the sound.
• Because this setting acts as an offset added to the output level set for the voice in
the PLG100-DX, it indirectly changes the timbre of the voice. When this parameter is set to zero, the voice will remain as is. Setting it to +1 or more will make the
sound brighter (increase the overtones), while setting it to -1 or less will darken it
(decrease the overtones).
PortaMd (Portamento Mode)
Settings: flw/ftm, rtn/fgr
Explanation:
• Portamento is an effect that produces a smooth glide between two notes of different pitch.
• The way in which the Portamento effect is applied is set with the Portamento
Mode. However, there will be a large difference in the effect depending on the
Poly/Mono setting for the selected voice.
When Poly Mode is set:
• When flw/ftm is set, the Portamento effect will also be applied to the sustained
sound from when the sustain pedal is depressed, and to the lingering sound after
the hand is removed from the key. The sound will change to the pitch of the next
note played.
• When rtn/fgr is set, the Portamento effect will not be applied to the sustained
sound from when the sustain pedal is depressed, or to the lingering sound after the
hand is removed from the key.
When Mono Mode is set:
• When flw/ftm is set, normal Portamento effect is applied.
• When rtn/fgr is set, the Portamento effect is only applied when the next key is
pressed while the first key is held down.
• In the DX7, each is called as follows:
flw: Sus-key P Follow
ftm: Full Time Porta
rtn: Sus-key P Retain
fgr: Fingered Porta
PortaStep (Portamento Step)
Settings: 0 to 12
Explanation:
• Sets the way in which the pitch is changed by the Portamento effect.
• The 0 value sets a normal continuous change.
• Setting 1 to 12 changes sound according to the scale. For example, if 1 is set, the
change is by semitones, if 2 is set, it is by whole tones.
23
Editing DX Part Parameters
PitBndStep (Pitch Bend Step)
Setting Values : 0 to 12
Explanation:
• Determines the way in which the pitch is changed by the pitch bend wheel.
• The 0 value sets a continuous change (the normal setting). Setting 1 to 12 changes the
sound according to the scale. For example, if 1 is set, the change is by semitones, if 2 is
set, it is by whole tones.
AC4 CC No. (AC4 Controller Assign)
Settings: OFF, MOD, BC, FC, EXP, CAT, PB
Explanation:
• When the AC4 controller parameter is set to EGbias, this parameter sets the controller
which operates EGbias.
• The settings indicate controllers as follows:
MOD ..... Modulation wheel
BC......... Breath controller
FC ......... Foot controller
EXP....... Expression pedal
CAT....... Channel aftertouch
PB ......... Pitch bend wheel
• When the amplitude modulation sensitivity of the selected voice has been set to carrier,
operating the controller that has been set in this parameter will change the volume in
realtime. When the amplitude modulation sensitivity has been set to modulator, the
timbre will change.
AC4CtrPrm1 (AC4 Controller Parameter 1)
Settings: Off, EGbias
Explanation:
This specifies whether the EGbias will be controlled by the controller that has been set
in the AC4 Control Change Number parameter.
AC4CtrDpt1 (AC4 Controller Parameter Depth)
Setting: -64 to +63
Explanation:
Specifies the depth of operation when EGbias is controlled by the controller that has
been set in the AC4 Control Change Number parameter.
• When AC4CtrPrm1 has been set to EGbias, the sound may change when AC4CtrDept1 is set positive, even
if the output from the controller set in AC4CCNo.is zero.
24
Editing DX Part Parameters
RcvDxSysEx (Receive DX System Exclusive)
Setting: OFF, ON
Explanation:
Specifies whether DX system exclusive messages will be received or not.
• The follow conditions must be met for DX system exclusive messages to be received:
With VCED, ACED (Parameter change, Bulk Dump)
With VMEM, AMEM: (bulk dump, 32 voice bulk dump)
Bulk select: Custom Bank
RcvDxSysEx: ON
RcvDxSysEx: ON
