1.1 INTRODUCTION
This manual is intended for all users that have upgraded their JX-10 to the new Vecoven firmware. If you’re not
sure what extra features are now available, read on. Or, if you are interested in something specific, you can jump
straight to the index to find what you’re looking for. To go to the index, click HERE.
To help with navigation, all words that are underlined and have hyperlinks on them can be used to jump directly to
the respective page.
The Roland JX-10 is a fully programmable 12 voice polyphonic synthesizer. Various sounds and performance
control functions can be stored, which can be immediately recalled and used.
•The JX-10 features a memory capacity that can retain up to 64 different programs (called “Patch Memory”)
which are the combinations of sounds (Tones) and performance control functions.
•Any of the Patch Memories can be recalled simply by pressing the appropriate buttons.
•Patch Memory you have written into memory can be easily edited at any time.
•Using optional M-64C Memory Cartridges, it is possible to expand the storage capacity.
•Thanks to the new and refined MIDI implementation the JX-10 can now be edited via sysex and dedicated
Editor Librarians such as EMAGIC SoundDiver®, SoundQuest MidiQuest®and other editors specially
designed for the Apple iPad. To dump and load patches there’s now no need to keep the M-64C cartridge
inserted.
•The 76 note keyboard and improved associated MIDI functions now serve to make the JX-10 an excellent
master keyboard.
New MIDI implementation
•Each parameter is now OFF/RECV/SEND/ON, allowing fine control of what gets sent and what is filtered.
•Sysex support : allows edit of patch, Tone A and Tone B individually. (No need for M-64C cartridge).
•Fast bulk dump/load : 4-5 seconds to dump everything. Can dump to/from cartridge and internal memory.
•Parameter edits (patch and tones) send sysex, so all edits can be sequenced. The PG-800 programmer is now
supported, so edits made from the PG-800 can also be sequenced.
•Copy from/to cartridge to create a full backup of the internal memory (all settings can now be copied to the
cartridge or restored from it).
•Later versions of firmware also have a few more additions. Check out the Firmware Versions - Page 64 for
further details.
Controls C1 and C2 enhancements
•Any tone parameter can now be assigned to C1 or C2.
•Any arpeggiator parameter can be assigned to C1 or C2.
•C1 and C2 can be used, in tone edit mode, to modify upper/lower tone parameters. This is a new feature and
allows quick editing of tones for those who do not own a PG-800 programmer.
Arpeggiator
•8 arpeggiator “patches”.
•Internal or external synchronisation.
•Supports up, down, up/down, as played and random note ordering.
•Various arpeggio types.
•Velocity setting (fixed or as played).
•Note duration (1-15 or legato).
•Use of lower split point to control which notes are arpeggiated.
PG-800 programmer support
•New display options.
•Control whether updates from sysex, PG-800 or controllers are displayed temporarily on-screen.
Compatibility mode
•Allows disabling of new features for full compatibility with old software (for example, sysex changes made to
tone A can be redirected to the currently selected tone, etc...)
Test modes
•Test hardware controllers (Voices, A/D controllers (Aftertouch, Bender, C1/C2), Keyboard)
•Test memory chips

1.2 IMPORTANT NOTES
•The appropriate power supply for this unit is shown on its name plate. Ensure that the line voltage in your
country meets the requirement.
•Do not use the same mains power socket as any device which inherently generates noise (such as high
voltage switching, motors, lighting system dimmers etc.).
•The unit may not work correctly if turned on immediately after it is turned off. If this happens, simply turn it off,
wait 10 seconds and turn it on again.
•Before connecting the unit to other devices, switch all of them off.
•The unit may generate slight heat when in operation. However, this is not cause for concern.
•To clean, use a soft cloth and use only mild detergent.
•Avoid use of any solvents (such as paint thinners etc.) on any surface of the device.
•Avoid using the unit in excessive heat or humidity conditions or where it may be affected by direct sunlight or
excessive dust.
•Save your sound data to a cartridge or make a data dump before having the JX-10 repaired, in case the
internal memory should happen to be accidentally erased.
•Before connecting or disconnecting the cartridge, be sure to set the Protect Switch to the ON position. To
prevent the accidental loss of the data, never move the Protect Switch to the OFF position, unless specifically
instructed to in the manual.

SECTION 2 – REAR CONNECTIONS AND SWITCHES
2.1 Total Mix Output Jack
Connect this jack to an amplifier. To make the best use of the JX-10, use an amplifier and speaker with wide
frequency response and dynamic range such as a keyboard amplifier or a pair of powered studio monitors.
2.2 Parallel Output Jacks
These are also for connecting amplifiers. Different methods of connection will yield various sound effects.
The following shows several different ways to use the Output Jacks.
Connection

When the JX-10 is set to Whole mode, connecting a stereo amplifier to the UPPER MONO and LOWER
MONO of the Parallel Output Jacks (output jacks B and C shown in the above picture) will cause the sounds to
be output irregularly through L or R. This is normal behaviour. In this case, use a different configuration.
2.3 Output Level Switch
Use this switch to select the best output level depending on the amplifier connected to the Total Mix Output.
* This switch does not work on signals sent from the Parallel Output Jacks.

2.4 Headphone Jack
Connect stereo headphones to this jack.
2.5 Hold Pedal Jack
By connecting the optional pedal switch DP-6 or DP-2, the Hold effect can be turned on or off by pressing the
pedal. "Hold" is the effect of holding the sound “on” even after a key is released (useful for piano sustain effects).
2.6 MIDI Connectors (In / Out / Thru)
These are for connection to other MIDI devices using MIDI/SYNC cables (optional).
2.7 Programmer Connector
Connect this to the optional PG-800 programmer using the supplied 6 Pin DIN cord.
2.8 Protect Switch (Internal Memory)
Always make sure that this switch is set to the ON position to protect the data in the JX-10, except when saving or
loading data.
2.9 Control Assign Jack
Use this jack when assigning Control Changes with the expression pedal or pedal switch.

SECTION 3 - OUTLINE OF JX-10 FUNCTIONS
The JX-10 features functions that are quite different from those of older synthesizers. Therefore, it is very important
to understand these functions. Read the following explanations, then go to “SECTION 4 - OPERATION”.
3.1 The JX-10 stores 100 different sounds (Tones) – 50 of them can be rewritten, the other 50 are
non-volatile. There are 64 combinations of Tones and various performance control functions (this
combination is called Patch Memory). That is, a Patch Memory consists of a Tone or a pair of
Tones and performance control functions which we call Factors in this manual. Normally, to
change sounds during a live performance, you would select a different Patch Memory.
(See page 10 “Selecting a Patch Memory”)
3.2 The Factors of a Patch Memory can be edited easily whenever you want.
(See page 17 “Editing a Patch Memory”)
3.3 The Tone of a Patch Memory can be edited just like you would on a normal synthesizer, A tone
consists of various parameters and a tone is edited by changing these parameters.
(See page 20 “Editing a Tone”)
3.4 To write the edited Patch Memory into the JX-10’s memory, follow the appropriate WRITE
procedure.
(See page 30 “Writing a Patch Memory”)
3.5 Using a Memory Cartridge (M-64C), the following data transfer is possible:
a) Saving of each Patch Memory/Tone to the memory cartridge and loading it back to the JX-10.
b) Saving the entire data (50 Tones and 64 Patch Memories) on the JX-10 to the memory
cartridge and loading it back to the JX-10.
(See page 35 “Memory Cartridge”)
3.6 Note that with the new firmware, the Sequencer (supplied as standard in the original unmodified
JX-10) is not present any more.
This has been replaced with a programmable 8 memory arpeggiator.
(See page 29 “Arpeggiator”)
3.7 All the Patch Memories and Tones can have their own unique names which can be changed as
necessary.
(See page 32 “Naming a Patch Memory”)
3.8 The JX-10 features MIDI functions necessary for operating with or being operated by, other MIDI
devices. The MIDI functions can be changed according to your requirements.
(See page 41 “MIDI”)
3.9 To make the above operations quicker and easier, the JX-10 has a display window. If you perform
an incorrect operation, the display will respond with an appropriate error message.
(See page 40 “Error Messages”)

SECTION 4 - OPERATION
Connect the JX-10 to the external devices (e.g. an amplifier and speaker), then switch it on. The JX-10 is now
ready to be played using any of the 64 Patch Memories.
A Patch Memory is made of one, or a pair, of the 100 different Tones and various performance control functions
such as Split Point, Bender Sensitivity, etc.

Manual Version 3.21
Page. 10 of 73
4.1 SELECTING A PATCH MEMORY
Make sure that the connections are made securely and correctly then switch the JX-10 on.
The Display will show “ROLAND JX-10” (plus the current version of firmware) for several seconds then change to
as shown below. Note each of the display areas A to E below:
A. The 64 Patch Memories are stored either in the JX-10's internal memory or on the optional Memory Cartridge
(M-64C). The display above (Area A) shows whether the Patch Memory currently selected is in the JX-10 or on
the Cartridge.
I : Internal Memory of the JX-10
C : Cartridge Memory
B. The 64 Patch Memories are stored in the locations of 8 Banks (A to H) and 8 Numbers (1 to 8). The above
display (Area B) shows the Bank and the Number of each Patch Memory.
C. Each Patch Memory can be named with up to 18 characters (this is called Patch Name). The patch name is
displayed in Area C.
D. The numbers 1 to 100 are assigned to the 100 Tones in the JX-10’s memory. The numbers of the Tones used
for the Patch Memory currently selected are displayed here. The Tone number of the LOWER section of the
keyboard is shown in Area D.
E. The numbers 1 to 100 are assigned to the 100 Tones in the JX-10’s memory. The numbers of the Tones used
for the Patch Memory currently selected are displayed in Area E as are the Tone numbers of the UPPER
section.
*The characters shown at Area A (Memory Mode) and at Area B (Bank / Number of Patch Memory) are always
displayed, except when in Writing (see page 30)and Master Tuning (see page 38)modes.
To select a Patch Memory, assign the Bank and Number using the Patch Memory Buttons. Using these buttons,
press a letter then a number (e.g. A, 2, - Patch memory A2 will be selected).
The JX-10 is designed to produce no sound while you are changing Patch Memories. This serves to mute the
transition noise from one preset to another which otherwise would be heard. If you do not want the sound to be
muted, instead of changing Patch Memories, change the Tones (See page 15).This method allows recall of the
required sound without any muting.

Manual Version 3.21
Page. 11 of 73
4.2 CONTROL KNOB FUNCTIONS
The following controls can be operated whilst you are playing the JX-10.
a. Control Assign sliders
Each of these two sliders can be used for controlling the performance control function you select with the Control
Assign button. (See page 12 “Control Assign”)
b. Bender lever - Bend Range switch
This Bender lever can be used during live performance for creating a guitar “choke-bend” effect. The left and right
extremes of movement create the same amount of pitch bend effect up or down. The maximum effect of the bender
can be selected with the Bend Range switch: major 2nd, minor 3rd, major 3rd, perfect 5th, perfect octave higher or
lower.
Pressing the Bender lever forward will create a vibrato effect. When the tone you are using already has vibrato
assigned to it, the effect will be deepened (unless it is already set to max).
c. Aftertouch Fine Adjust slider
The Aftertouch effect is the ability to change the sound by the amount of downward pressure applied to the key (or
keys). When a note or chord is played, pressing harder generates an Aftertouch signal proportional to how “hard”
you press. The JX-10’s Aftertouch effect works on the Vibrato, Brilliance and/or Volume.
Vibrato:
The depth of the vibrato effect is deepened.
Brilliance:
The tone will become brighter.
Volume:
The volume of the sound will increase.
The On/Off setting or value of each Aftertouch effect
can be written to each Patch Memory independently
but the Aftertouch Fine Adjust knob
allows even
more delicate adjustment of the effect.
When this
knob is set to the center position, the same effect as
set in the Patch Memory can be obtained, and no
effect is obtained at the lowest position [-].
* Different On/Off settings and values of the
Aftertouch and Bender are written to each of the 64
Patch Memories. Therefore, the actual effect you
hear can differ depending on how these are set up in
each of the Patch Memories: No
effect may be
obtained in some particular settings.
d. Voice Memory switch
This switch selects which memory mode; the JX-10’s Internal memory or the Cartridge memory is to be used.

Even after you have changed Memory modes with the Voice Memory switch, the new selected position does not
affect the memory until you select a NEW Patch Memory.
When you select a new Patch Memory, “I” (Internal) or “C” (Cartridge) is shown at the left end of the Display,
(Area A) depending on which position has been selected with the Voice Memory switch.

Manual Version 3.21
Page. 12 of 73
* When the Memory Cartridge is not connected, be sure to set the Voice Memory switch to the “INT” position.
4.3 CONTROL ASSIGN
The JX-10 allows you to control some of the performance control functions with the Control Assign knobs on the
control panel and the Pedal Switch (DP-6 or DP-2). This is excellent for live performance. However, the functions
which can be controlled are only two of the four with the two Control Assign knobs and one of the four by the pedal
switch at a time. (See the table shown on the next page). The following explains how to assign the functions to the
knobs and the pedal switch. The function assigned to each knob is controlled by moving the slider, and the function
assigned to the pedal switch is controlled with the pedal operation.
We call these eight functions “Control Assign functions”.
PROCEDURE
1. Select the Control Assignment C1, C2 or Pedal
Switch where you wish to assign the function by
pressing the appropriate Control Assign button;
C1, C2 or PEDAL SWITCH.
The Display will now show the Control Assign
function that has been selected.
2. Rotating the αDial, call the new function to be
assigned.
(See the table shown on the next page)
3. To continue to assign other functions, repeat
steps 1 and 2.
4. When you have completed assigning all the
Control Assign functions, press the Control
Assign button currently in use.
The Display will return to its normal indication. Whilst the Display shows the Control Assign function, nothing can
be done on the JX-10 except for playing the keyboard.
Note: When Expression Pedal EV-5 is connected to the Control Assign jack on the rear panel, the assigned Control
Assign function cannot be controlled with the Control Assign knob - only with the pedal.
Writing the Control Assignments
The Control Assign functions you have set can now be written into the JX-10’s internal memory as follows:
After step 3, set the Protect Switch on the JX·10 to the OFF position, then press the WRITE Button.
The Display will respond as above, then return to its normal indication.

4.4 PATCH MEMORY - QUICK EDIT
The following three Factors can be quickly edited (even during live performance) simply by pressing the relevant
button.
•Key Mode Select: Whole (Upper, Lower), Dual and Split
•Tone Number: Tone(s) in a Patch Memory
•Chase Play: When the Key Mode is set to Dual, delay-like effect can be obtained
*The above editing function does not automatically rewrite the data to memory unless you select the appropriate
WRITE procedure. (See page 33).Therefore, selecting a new Patch Memory will erase the just-edited data.
a. Key Mode
There are 6 Key Modes:
1. UP WHOLE
2. LO WHOLE
3. DUAL
4. SPLIT
5. T-VOICE
6. X-FADE
Key Modes 1 – 4 can be recalled with Quick Edit. Key Modes 5 - 6 can be set only when editing the Patch Memory.
The three Key Mode Buttons are used for setting Key Mode. Press a button and it will illuminate.
Split Mode
This mode divides the keyboard of the JX-10 into the upper and lower sections where two different Tones can be
used. This means that the JX-10 works like two 6 voice synthesizers each with different sounds.
The JX-10's unique Split system allows setting of the lowest key in the Upper section and the highest key of the
Lower section separately on the same keyboard. Quick Edit, however, does not include this function. This is
possible only when editing a Patch Memory.
PROCEDURE
Hold the SPLIT Key mode Button down, then press the key which is to be the Split
Point.
•Whilst holding the button down:
•Press the Key where the keyboard should be divided into two sections, Upper
and Lower.
•The right side (including the pressed key) will become the Upper keyboard and
the left side will become the Lower keyboard.
Whole Mode
In this mode, the JX-10 can be used as a 12 voice polyphonic synthesizer. That is, all 76 keys will have the same
Tone. Therefore, it is required to select one of the two different Tones provided for the Upper and the Lower
sections. When the Tone for the Upper section is selected, it is called Upper Whole Mode, and when the Lower
Tone is selected, called Lower Whole Mode. Pressing the Whole Button will alternately select the Lower and Upper
Tones. The Display shows the Tone Number currently selected.
Dual Mode
Dual Mode turns the JX-10 into 6 voice synthesizer mode which allows both the Upper and the Lower Tones to
sound simultaneously. A richer sound is obtained. There are two independent parallel outputs for the Upper and
Lower Tones, which serve to create an effect as if two synthesizers were being played simultaneously.

Manual Version 3.21
Page. 15 of 73
b. Tone Number
To change the Tones in a Patch Memory, simply assign the Tone Number of the relevant Tone by using the Ten
Keys (i.e. the Numeric Keypad).
PROCEDURE
1. Press the Upper or the Lower Button to select the Upper or Lower Tone which you wish to change.
2. Pressing the appropriate Ten Keys, assign the new Tone Number, then press the ENTER Key.
*”0” of the Ten Keys can be used instead of the UPPER and LOWER Buttons.
Even when using the Patch Memory (the JX-10’s internal memory), the Tone Number of a Cartridge can be
recalled.
After taking step 1, change the Voice Memory Switch to the CART position. Then return it to the INT position after
taking step 2.
If you call another Patch Memory without writing the current one into memory first, the Tone called from the
Cartridge memory will be erased.
To call the Tone from the Memory Cartridge (M-64C), use exactly the same procedure as above. The available
Tone Numbers, however, are from 1 to 32.
c. Chase Play
The Chase Play function makes it possible to output the Lower sound slightly later than the Upper sound. This
function, however, is available only in Dual Mode.
Depending on the delay time and the Tone in use, the effects created can differ; delay-like effect, sound-on-sound
effect etc.
PROCEDURE
1. Press the Chase Play ON/OFF Button: The corresponding indicator will light up, showing that the Chase Play
function is turned on.
2. Set the following 3 functions: Time, Level and Mode so that the desired effect is obtained.
The “Level” and “Mode” are alternately selected by pressing the FUNCTION Chase Play Button.
The Display shows the function selected. The “Time” function can be selected by pressing the TIME Chase Play
Button. The value of the selected function can be changed by using the αDial.
1) Level
This sets the level of the delayed sound (= Lower sound). Rotate the αDial, to set the required value. The value
can be set from 00 to 99. The higher number sets a higher level.
**: 00 to 99

2) Mode
This sets how the delayed sounds are output sequentially. As you rotate the αDial, the Display changes as follows:
“U – L - U“ / “U – L - L“ / “U - L”
•Key Mode Select: Whole (Upper, Lower), Dual and Split
•Tone Number: Tone(s) in a Patch Memory
•Chase Play: When the Key Mode is Dual, delay-like effect can be obtained

3) Time
This sets the time between the first (Upper) sound and the second (Lower) sound.
Press the TIME Chase Play Button to select Time Adjust mode, then change the value using the αDial. Choose a
value from 01 to 99. The higher number represents a longer time.
**: 01 to 99
When you have completed editing all the functions, press the ENTER Key.
*If the level described on the previous page in “1) Level” is set high and the key aftertouch is set to a high value,
more delay sound from the “Lower” sound can be obtained. If the Tone Parameter Number 63 “VCA Dynamics
Range” is set to OFF, the volume of the sound does not change, but repeats at the same volume.

4.5 EDIT PATCH PARAMETERS
The Tones and Patch Memories written to the JX-10’s internal memory or to the cartridge memory can be edited to
your taste. This editing does not automatically rewrite the previous data. To write the edited data, execute the
WRITE procedure (See page 30)
a. Editing a Patch Memory
Each of the A-1 to H-8 Patch Memories consists of 39 different Factors and changing the values of these Factors
will edit a Patch Memory. Editing is quite simple; the value of each Factor has two figure number, so use the
appropriate number to call the Factor whose value you wish to change, then change it.
Patch Factors can be recalled through the numeric keypad 0 – 9.
Patch Factors can be assigned to C1/C2 sliders, pressing C1/C2 buttons and selecting the relevant Patch Factor
via the αDial. In this way, two selected Patch Factors can be controlled in real time.
#
Parameter
Range
Description
11
UPPER/LOwER BALANCE
00 to 99
This Factor determines the volume balance of the
Upper and the Lower. When the value is about 50, the
volumes of the both sections are the highest, and as
the value increases, the Lower volume decreases, the
Upper volume remaining the highest. That is, when the
value in the Display is 99, only the Upper sound will be
heard. When the value is smaller than 50, the opposite
effect will be obtained.
12
DUAL DETUNE
-50 to 00 to +50
This Factor can detune the Lower sound from the
Upper sound. At a “+” value, the Lower sound pitch is
raised. At zero, the pitch is thesame as the Upper, and
at a “-“value, the pitch is lowered.
13
Upper split point
E1 to G7
The Split Point set with Quick Edit is restricted to the
lowest note of the Upper section. Here, however, these
two Factors are used for setting two different Split
Points; the lowest note of the Upper section, and the
highest note of the Lower section. (The value and the
note name). The lowest note is E1, middle C is C4 and
the highest note is G7. (“+” indication represents #.)
14
Lower split point
E1 to G7
15
Portamento Time
00 to 99
This Factor adjusts the Portamento time.
Higher values increase Portamento time.
16
Bender ranGe
2, 3, 4, 7, 12
This Factor sets the maximum effect of the Bender.
The value in the Display represents semi-tones. “2” is
Major 2nd, “3” is Minor 3rd, “4” is Major 3rd, “7” is Perfect
5
th
and “12” is Perfect Octave.

however can be set.
T. Voice and X-Fade can be selected by rotating the α
Dial counterclockwise. Other modes can be selected by
rotating it clockwise.
T.Voice
x-fade
Touch Voice Select Mode (T. VOICE)
In this mode, either the Upper or Lower Tone is output
depending how you play the keyboard. That is, when
you play the keyboard
hard, the Upper Tone Is
selected, and when you play softly, the Lower Tone
sounds. As shown in the left picture, the key touch
pressure that selects the Upper or the Lower Tone
changes depending on the Upper Split Point (= Factor
13). When the Split Point is set to a higher note,
heavier key touch will be required to obtain the Upper
Tone.
Cross FadeMode (X-FADE)
This is a kind ofDual mode.
In this mode, the volume of the Lower Tone decreases
with heavier key touch, and the volume of the Upper
Tone decreases by weaker key touch. This mode,
therefore, can be effectively used to change the volume
balance of the Tones
by changing the manner of
playing when you are using different Tones for Upper
and Lower.

and lower. If a number higher than +5 is assigned, the
highest octave substitutes it, and if a value lower than
-7 (such as -8, -9 etc.) is assigned, the lowest octave
substitutes it.

POLY 1
This mode turns each of the Upper and the Lower
Keyboards of the JX-10 into a 6 voice polyphonic
synthesizer assigning one synthesizer module to each
key pressed. This is suitable for a
sound whose
envelope curve is similar to a piano or guitar and is
therefore chosen for usual performance.
POLY 2
This mode is very similar to Poly mode above
assigning only one synthesizer voice to each key
pressed. However, the same module as assigned to
the key previously played is
assigned to the note
played later. So, this mode is suitable for performance
with using a portamento effect.
UNISON 1
In this mode, two sound modules are assigned to each
key, therefore the created sound is richer than in Poly
mode. i.e: each of the Upper and the Lower sections
becomes a 3 voicesynthesizer.
UNISON 2
This is similar to Unison 1 mode above, but one of the
two modules is assigned to be one octave lower than
the other.
MONO 1
This mode turns each of the Upper and the Lower
keyboard into a single voice synthesizer that assigns
one module to each key.
MONO 2
This mode turns each of the Upper and the Lower
keyboard into a monophonic synthesizer that assigns 6
modules to one key pressed.

The Upper and the Lower sections of the keyboard can have different Key Assign modes, which gives various
interesting combinations. However, please note that when Whole key Mode is selected, the Key Assign Factor you
set will be ignored. When Portamento is turned ON, Poly 2 is automatically selected. When it is OFF, Poly 1 mode
is selected. Also, when Key Mode is either set to Touch Voice or Cross Fade, the Key Assign parameter selected
on the Lower will be ignored and the Upper Key Assign of the Upper takes effect.

The Chase Play function makes it possible to output the Lower sound slightly later than the Upper sound. This
function, however, is available only in Dual Mode. Depending on the delay time and the Tone in use, the effects
created can differ; delay-like effect, sound-on-sound effect etc.
PROCEDURE
1. Press the Chase Play ON / OFF Button. The corresponding indicator will light up, showing that the Chase Play
function is turned on.
2. Set the following 3 functions: Time, Level and Mode so that the desired effect is obtained.
The “Level” and “Mode” are alternately selected by pressing the FUNCTION Chase Play Button.
The Display shows the function selected.
The “Time” function can be selected by pressing the TIME Chase Play Button. The value of the selected function
can be changed by using the αDial.

Chase play level
00 to 99
This sets the level of the delayed sound (= Lower
sound).
Rotate the αDial, to set the required value. The
value can be set from 00 to 99. The higher number
sets a higher level.

This sets how the delayed sounds are output
sequentially. As you rotate the αDial, the Display
changes as follows: "U-L-U", "U-L-L" or "U-L".
•U-L-U: In this mode, Upper sound is output
first, then Lower, Upper, Lower repeatedly.
•U-L-L: In this mode, Upper sound is output
first, then Lower sounds repeatedly.
•U-L: In this mode, Upper sound is first output
then Lower. No moresound is output.

Chase play time
01 to 99
This sets the time between the first (Upper) sound
and the second (Lower) sound.
Press the TIME Chase Play Button to select Time
Adjust mode, then change the value using the α
Dial. Choose a value from 01 to 99. The higher
number represents a longer time.
When you have completed editing all functions,

4.6 EDITING PROCEDURE – PATCH MODE (a)
1. Press the PATCH Edit button.
The PATCH button indicator lights up showing that you are now in EDIT mode. The Display changes as shown
below.
A. Factor Number and Factor Name are displayed
B. The value of each Factor is displayed
2. Using the Ten Keys, assign the number of the Factor whose value is to be changed. As shown below,
press the Ten Keys in the correct order to select the Factor number, then press the ENTER Key.
3. Using the αDial, change to the desired value. It may be necessary to actually listen to the sound while
changing the value.
4. To continue to edit other Factors, repeat steps 2 and 3.
It is also possible to use the αDial to call a Factor. After pressing the PARAM button, rotate the αDial, and the
Factor shown in the Display will change sequentially. When the Factor you wish to edit appears in the Display,
press the VALUE edit button, then change the value with the αDial.
This method is useful for when you are editing the Factor of a number close to what is already selected. However,
to continue to edit other Factors, be sure to press the PATCH then the PARAM buttons - then call the Factor you
want by using the αDial.
When you have completed editing the Patch Memory, press the PATCH button. The PATCH indicator goes out and
the display returns to the usual indication except that the Bank and the Number of the Patch Memory flash -
showing that the Patch Memory has been edited but not yet written into memory. If you call another Patch Memory
at this stage, the edited Patch Memory will be erased. If you wish to keep your edit, execute the WRITE procedure.
b. Editing a Tone
A Tone consists of various parameters. Like any normal synthesizer, the JX-10 allows editing of these parameters
for sound synthesis. The JX-10, however, does not feature knobs or switches on its panel for you to touch or move.
Instead, there are two methods of synthesizing. One is to call each parameter and change the value. This method
does not allow editing of more than one parameter at a time, so may be used for making a slight edit during live
performance. Another method is to use the optional PG-800 programmer which works just like the panel controls
on a regular synthesizer. For quicker and easier editing or synthesis from scratch, the PG-800 may be essential.
1. Editing using the PG800 Programmer
As shown, connect the programmer and the JX-10 using the 6 pin DIN cable.
The PG-800 works just like the control panel of a normal synth, i.e., you can edit
the existing Tone or make a complete new Tone from scratch by actually using
physical sliders, knobs and buttons. Note: The PG-800 does not work when the
JX-10 is in WRITE mode.
