CHAPTER 1
DX1 OLTTLINEn-HE FM VOICE GENERATOR SYSTEM
1-1 DX1 System Outline
The block diagrem in figure 1roughly
outlines the DXl system. It consists of
four main sections:
(1) CONTROL PANEL
(2) FM TOIIE GmERATOR
(3) DIGITAL EG
(4) KEYBOARD
The simplicity of the systeir: nas oeen made
possible because it functions mostly on
digital principles. Based on the clock
diagram in figure 1, we'll roughly describe
each section.
(1) CONTROL PANEL
Almost all controls are logic control
switches. Other features on this remarkably
simple panel include agraphic LED display,
an alphanumeric LCD display, afew linear
controls and controller wheels.
(2) FM TONE GENERATOR
In addition to pitch, timbre and level
programming capability, these sophisticateo
tone generators are also capable of
generating noise components like those found
in natural sounds and acoustic instruments.
They offer unprecedented precision and
versatility in voice creation.
(3) DIGITAL EG
This system permits programming time-based
variations of pitch, timbre and level.
Because it is adigital system, the EG curve
can be precisely programmed in numeric form.
Further, the digital EG has 8variable
parameters permitting exceptionally
versatile EG curve generation,
(4) KEYBOARD
This is a73-key, 32-note polyphonic
keyboard with three touch functions: key
velocity sensitivity (initial touch), after
touch, and key individual after touch. This

offers greatly expanded expression

precision weighted-return action for the
most natural overall keyboard response.
1-2 THE FM TONE GENERATOR
The Yamaha FH tone generator permits precise
control over voice pitch, timbre and level.
The following is abrief description of Fr:
tone generator principles. See Chapter 9
for amore technical explanation of Fii tone
generator theory.
What is Fii? "
FM stands for Frequency Modulation, just as
it does when used to describe an "FM"
station or radio broaacast.
The term "modulation" means, basically, to
superimpose one signal on top of another
signal. In other words, asignal of agiven
pitch may be used to "modulate" asignal of
another pitch. The vibrato effect is an
example of alov7-f requency signal (the
vibrato) modulating ahigh-frequency signal
{the note to which vibrato is applied).
In an FH radio broadcast, a"carrier" —an
extremely high-frequency radio signal which
can be transmitted via the atmosphere—is
used to "carry" the program material. The
program material "modulates" the
radio-frequency carrier.
In the FM tone generator, the carrier and
modulator function as follows:
CARRIER: determines the level and pitch
of the sound.
MODULATOR: determines the timbre of the^
sound, "
Of course, the carrier and modulator
frequencies are much closer together in the
FM tone generator than they are in an FM
broadcast, and they are both pure sine
waves.
The 2Main Merits of FM
In an FM broadcast, since the carrier
frequency is somewhere around 80 million
hertz (cycles) and the music signal which
moaulates it contains frequencies which are
much lower—20 Hz to 20,000 Hz, the music
signal is basically unchanged by the
carrier. If we bring the frequencies of the
carrier and modulator much closer together,
however, we begin to generate new signal
components—harmonics of the modulator
and/or carrier and noise components.
It is these modulator-carrier
characteristics that we take advantage of in
the FM tone generator. Its first big
benefit is that the FH generator is capable

of closely controlling the pitch, tin.bre and
level of the sound produced without the need
for conventional VCO (Voltage Controllea
Oscillator—pitch control) ,VCF (Voltage
Controlled Filter—Timbre) or VGA (Voltage
Controlled Amplifier—level) elements.
Further, while the conventional VCF controls
timore by removing certain harmonics from
the sound, the FM tone generator works by
adding harmonics as required—and where
required—for much more sound control
versatility. In fact, the harmonic spectrum
of avoice can programmed with total
freedom.
Another rrajor oenefit of the FM system is
that noise components that conventional VCOs
are simply incapable of producing can be
easily generated. Noise is avery important
part of the sound of any acoustic
instrument—not just the instrument's pure
tonal harn.onics. For example, in aviolin
there is bowing noise, breath noise in a
saxophone sound, or the purely percussive
portion of adrum sound. The FH tone
generator system permits producing total
^pound such as these, incorporating both
surely tonal and noise spectra.
Specifically, random harmonic structures and
noise can be produceo by setting the ratio
of modulator and carrier frequencies so one
is not amultiple of the other, and by
greatly increasing the modulation level. Of
course, it is then possible to use the DXl
EG to independently control different
portions of the sound.
The FM Tone Generator and Algorithms
The DXl has two FK tone generator
channels—Aand B. Each channel has 6
OPERATORS—atotal of 12—which are the
basic FM voice building blocks. An operator
is essentially asine wave oscillator that
can be used either as amodulator or as a
carrier. Furthermore, since the DXl is an
all-digital instrument, these sine wave
oscillators function by "reaoing" the sine
wave from adigital sine wave memory, rather
^han by using conventional analog oscillator
Jpircuitry, for exceptional precision and
Stability.
The six operators in each channel can be
combineo in many ways, with different
configurations and mooulator-to-carrier
relationships. Such operator "patterns" are
called ALGCRITHilS. The simplest form of
algorithm is acombination of two
operators—one acarrier and one a
modulator. This combination is shown in
fig. 2below.
Fig. 2. FM Sound Source Basic Algorithm
Hodulatoc
Carrier
JJ
4. Modulation Signal
^Audio Signal
Vv'ithout any modulation, an operator produces
apure sine wave with absolutely no harmonic
content other than the fundamental
frequency. V/hen modulation is applied,
however, arather complex waveform with a
complex harmonic structure is produced (fig.
3). There are three main ways of
controlling the resultant waveform. They
are:
The frequency ratio between modulator and
carrier.
Modulator output level.
Feedback.
The DXl uses all three of these control
elements to create an unbelievably broaa
spectrum of natural voices.
Fig. 3. FM Waveform Variation
Waveform before modulation
by carrier. {Sine Wave) Waveform after modulation
by carrier. (Complex wave)
The actual algorithms used in the DXl are a
little more complex than the one shown
above. Carriers may be arranged "side by
side" as shown in fig. 4, or n.any
modulators may be piled on top of one
another to create a"chain" of modulation.
Figures 5—7are examples of actual DXl
algorithms, 32 different algorithm patterns
are provided, and can be used independently
in channels Aand B. The two channels can
then be mixed in any way desired to create a
range of voices unprecedented in any
electronic music synthesizer system.

CHAPTER 2
DX1 FEATURES AND FUNCTIONS
Despite of the fact that the DXl has avast
number of functions, its control panel is
remarkably simple. This has been made
possible by the use of many multi-function
switches that change their function
according to the number of times they are
pressed. This system of providing many
functions with the smallest number of
switches is similar to that of using an
alphanumeric keyboard for inputting commands
on alarge computer. In this section we
will briefly introduce the features and
functions of the DXl control panel.
2-1 TTie 4modes of the DX1
The DXl has four main modes. These are
selected using the MODE selectors. Each
mode has its own set of parameters,
PLAY MODE
In this mode, voice and effect data called
can be used directly in performance.
Although there is no specific switch for
this mode, it is the basic mode selected
when the three modes described below are all
turned OFF, In the play mode, the
PERFORMANCE MEMORY/FUNCTIOH and VOICE MEMORY
buttons become the play mode voice
selectors.
EDIT MODE
In this mode voice data can be programmed.
Data already contained in the voice memory
can be edited and changed, or completely new
voices can be created simply by inputting
the appropriate data. The edit mode takes
priority over the play mode,
FUNCTION MODE
In this mode the many effects used during
performance can be set. Commands related to
memory control and the MIDI terminal are
also included in this mode. This mode takes
priority over both the play and edit modes. ^
STORE MODE ^
In this mode data can be stored in the voice
and performance memories. Voice parameters
in the EDIT mode can be memorized in the
VOICE MEMORY, and function parameters and
VOICE MEMORY numbers can be combined and
recorded in the PERFORMANCE MEMORY. The
store mode takes priority over the play,
edit and function modes.
2-2 Control Panel (fig. 8)

CHAPTER 3
PLAY modePERFORMANCE MEMORY
In the PLAY raode, data already in the memory
is used for performance. In this section
we'll describe how to call out the required
voice for performance, and how memory
positions can be changed without altering
the voice or performance data.
3-1 PERFORMANCE MEMORY &VOICE MEMORY
What is PERFORMANCE MEMORY?
In the DXl the two channels of internal
VOICE MEMORY or external cartridge VOICE
JIEMORY are combined with the FUNCTION raode
jHjffects to form the complete performance
~oices. The PERFORMANCE MEMORY is amemory
in which the VOICE MEMORY numbers are
combined with effects and stored. Channel
A/B corabinations and the addition of effects
can be freely set up and stored in the
PERFORMANCE MEMORY. In the PLAY mode
complete voices can be easily selected using
the PERFORMANCE MEMORY switches. ^P.12
*When the DXl is initially shipped, its
PERFORMANCE MEMORY contains 64
combinations pre-programmed at the
Yamaha factory, permitting immediate
performance when the instrument is
received. The PERFORf-J^ICE MEMORY
banks 1—4hold the internal voice
memory, and banks 5—8select the DXl
VOICE ROM cartridge side II memory.
*Voice and effect combinations are
stored in the PERFORMANCE MEMORY as a
number. The actual voice data {the
EDIT mode parameters) are not
memorized.
•* The internal RAM (Random Access Memory)
VOICE MEMORY can be used to store all
EDIT raode parameters. When the
instrument is initially shipped, the
VOICE MEMORY contains 32 voices in
each channel, Aand B, for atotal of
64 voices.
*The 5ROM (Read Only Memory) cartridges
provided contain original Yamaha
voices and effect data.
*The two DXl VOICE ROM CARTRIDGES each
contain 64 voices for atotal of 128
voices. Each cartridge has two sides:
Iand II. The I/II switch is used to
select the desired side. Side I
contains the same voices as are
initially stored in the instrument's
internal memory, and side II contains
different voices. Be sure to switch
to the desired side before plugging a
cartridge into the DXl. ^p.13
*The two DX7 VOICE ROM CARTRIDGES
provided also contain 64 voices each
for atotal of 128 voices.
*The PERFORI'IANCE ROM CARTRIDGE contains
the same 64 effect "settings" as the
DXl internal PERFORMANCE MEMORY. When
this cartridge is inserted into the
pxl, the data it contains is called
into the internal memory, combined
with the desired voice data and used
rCor performance.
Up to 32 original voices {voice
parameters) or 64 original effects
(function parameters) can be stored in
the RAM cartridges. When aRAH
cartridge is plugged into the DXl,
original data can be freely called
from it.
The RAM cartridges are initially
shipped set up with the VOICE MEMORY
(voice parameter) format. To use the
RAM cartridge for PERFORMANCE MEMORY
storage (function parameters), use the
FUNCTION mode CHANGE CART, FORMAT -*P.46
function.
The BUFFER
The buffer is aspecial separate memory
into which DXl data is called from
memory for performance or editing, A
buffer is provided for the PERFORMANCE
MEMORY and the VOICE MEMORY. When a
memory number is selected, the data
corresponding to that memory number is
read into the buffer (fig. 10),
In the PLAY mode data read into the
VOICE EDIT BUFFER and PERFORMANCE EDIT
BUFFER is used as is for performance.
In the EDIT mode VOICE MEMORY data is
read into the VOICE EDIT BUFFER for
editing.

*In the FUNCTION mode PERFORMANCE MEMORY
effect data is read into the
PERFORMANCE EDIT BUFFER for editing.
*In the STORE mode, data in the VOICE
EDIT BUFFER or PERFORMANCE EDIT BUFFER
is stored or copied into the VOICE
MEMORY or PERFORMANCE MEMORY.
*In the DXl the memory backup system
also provides backup power to the
buffer data. When the DXl power is
turned OFF, the basic data which was
being used at the time is held in
memory, and is available immediately
power is turned back on.
3-2 Calling Memory Data
(1) Calling the DXl PERFORMANCE MEMORY (fig,
11)
With the PERFORMAlN'CE MEMORY it is possible
to call out voice data and effect data
simultaneously. At the same time the effect
data is called into the PERFORMANCE EDIT
BUFFER, the selected voice number data is
called into the VOICE EDIT BUFFER.
(a) Turn all MODE selectors (EDIT,
FUNCTION, STORE) OFF.
*It does not matter if the EDIT switch
is flashing at this time.
(b) Insert two VOICE MEMORY CARTRIDGES
into the DXl,
(c) Using the upper row of 8bank
selectors in the PERFORMANCE
MEMORY/FUNCTION section, select the
desired bank number, and select the
desired voice +effect with the lower
row of 8buttons.. In this way atotal
sound, incorporating the voice data
and effects, is called,
*As shipped, banks 1—4contain the
internal DXl VOICE MEMORY, and banks
5—8contain the cartridge voice data.
(d) The LCD display displays the
performance name as "PERFORMANCE
MEMORY #1-1 **XXXX**'', or the voice
name as "INT Al-1 YYYY POLY SRC=0 INT
Bl-1 2ZZZ POLY SRC=0'',
*The "ftl-l" in the performance name
display is the memory number, and XXXX
is the performance name (fig. 12),
*In the voice name display the upper and
lower rows display the channel Aand B
voice names, respectively, "INT Al-1"
and "INT Bl-1" are the memory numbers,
while "YYYY" and "ZZZZ" are the voice
names. The data following "POLY" are
Fig, 11. Calling Internal Performance Memory
function parameters that need to be
checked for performance (fig, 13) .-/>.35
*The voice name and performance name
display can be switched by pressing
the bank selectors.
*When the KEY ASSIGN MODE is set to
SINGLE, the voice name displayed is
either that of channel Aor B
depending on which is in use.
*If a PERFORMANCE MEMORY CARTRIDGE (i.e.
acartridge formatted for PERFORMANCE
MEMORY) is inserted in the DXl,
selecting banks 5—8results in a
momentary "**ERROR** Cartridge format
conflicti" message, and the voice
data will be called from the internal
VOICE MEMORY, banks 1—4, In this
case go back to step (b) above and
repeat the process correctly.

In the PLAY mode it is possible to use the
DXl VOICE MEMORY switches to directly call
VOICE MEMORY data into the VOICE EDIT BUFFER
without calling aPERFORMANCE MEMORY (in
which the voice number is combined with
effect data) and add effects as required
while playing.
(a) Turn all MODE selectors OFF.
(b) Use the bank select switches in the
VOICE MEMORY switch group to select
the desired banks for channels Aand
B.
*If the KEY ASSIGN MODE is set to SINGLI
then only channel Aor channel B,
whichever is in use, needs to be set,
(c) Then, using the VOICE MEMORY voice
switches, select the desired voice
number. This causes the selected
VOICE MEMORY data to be called into
the VOICE EDIT BUFFER,

"INT" portion of the display indicates
that the internal memory is selected.
*The performance name will not change
even if the VOICE MEr40RY buttons are
pressed,
(3) Calling acartridge VOICE MEMORY
It is also possible to use the DXl VOICE
MEMORY switches to directly call VOICE
MEMORY CARTRIDGE data into the VOICE EDIT
BUFFER for performance. In particular this
process is suited for calling voice data
from the DX7 VOICE ROM CARTRIDGES.
(a) Turn all MODE selectors OFF.
(b) In the case of aROM cartridge set
the cartrdge bank selector switch
before inserting the cartridge.
(c) Insert the cartridge into the
Ik cartridge slot.
W(d) Press the CARTRIDGE switch to
initialize the cartridge access mode.
*If the CARTRIDGE switch is pressed
without inserting acartridge the LCD
display will show ***ERROR** Cartridge
not ready!". In this case go back to
step (c) and properly insert the
cartridge,
*If aPERFORI-iANCE MEMORY CARTRIDGE (a
cartridge formatted for PERFORMANCE
MEMORY) is inserted, the ''**ERROR**
Cartridge format conflict!" message
will be displayed. In this case the
data originally in the buffer will not
be affected. Go back to step (c) and
insert the correct cartridge.
(e) Using the VOICE MEMORY BANK switches
select the desired bank.
*If the KEY ASSIGN MODE switch is set to
SINGLE, then only channel Aor B,
whichever is in use, needs to be set.
(f) Using the VOICE MEMORY voice switches
select the desired voice number. This
causes the selected cartridge voice
number to be called into the VOICE
EDIT BUFFER ready for performance.
*The effects are set up according to the
currently selected PERFORMANCE MEMORY
unless the FUNCTION mode is used to
reset the PERFORMANCE MEMORY
parameters.
(g) The voice name display displays the
name of the voice called from the
catridge,
*The "EXT" portion of the display
indicates that the external cartridge
memory is being used.
(4) Calling acartridge PERFORMANCE MEMORY
(fig. 16)
It is possible to call PERFORMANCE MEMORY
CARTRIDGE data into the PERFORMANCE EDIT
BUFFER and call internal VOICE MEMORY data
into the VOICE EDIT BUFFER, combining the
two for performance,
*The method for calling data from the
PERFORMANCE MEMORY CARTRIDGE is
different from that for calling data
from aVOICE MEMORY CARTRIDGE, so care
should be taken to follow the correct
procedure,
(a) Turn all MODE selectors (EDIT,
FUNCTION, STORE) OFF.

has been accessed, the last section of
the upper row of the performance name
display will read '•<<CARTRIDGE»''
.
*If a PERFORMANCE MEMORY switch is not
held, or it is released before the
CARTRIDGE button is pressed, or a
VOICE MEMORY CARTRIDGE is inserted
instead of aPERFORMANCE MEMORY
CARTRIDGE, the '•**ERRROR** Cartridge
format conflictl" message will be
displayed, and the desired data will
not be read.
(d) Then by using the PERFORMA^iCE MEMORY
bank and PERFORMANCE &VOICE switches,
the desired effect data can be called
into the PERFORMANCE EDIT BUFFER.
*Only cartridge data which is called
into the PERFORMANCE EDIT BUFFER can
be used. Once the cartridge is
removed from the cartridge slot, all
other PERFORMANCE MEMORY positions
other than the one that was called
into the PERFORMAl^JCE EDIT BUFFER can
no longer be used. Further, if the
CARTRIDGE switch is turned OFF then
the internal PERFORMANCE MEMORY will
be called into the PERFORMANCE EDIT
BUFFER and the cartridge data will be
lost.
*If the effect data in the PERFORMANCE
EDIT BUFFER needs to be saved, use the
store performance function, -^p.S3
*In order to use all the PERFORMANCE
MEMORY CARTRIDGE data in the internal
memory, use the load function, ~*p.46
*Since the PERFORf-lANCE ROM CARTRIDGE
supplied with the unit contains the
same data as the internal PERFORMANCE
MEMORY at the time of shipping, only
banks 1—4can be used, VOICE MEMORY
CARTRIDGE data is set for banks 5—8,
however, since aVOICE MEMORY
CARTRIDGE cannot be inserted, the
internal VOICE MEMORY data is
automatically used,
(e) The performance name and voice name
are displayed on the LCD display each
time the bank switches are pressed.
The performance name display is
"PERFORIiANCE MEMORY #1-1 <<CARTRIDGE>>
**XXXX**".
*When the supplied PERFORMANCE MEMORY
ROM cartridge is used and one of the
banks 5—8is selected, "Cartridge
format conflict!" will be displayed
momentarily before the performance
name. As for the voice name, the
lower display row will read •'**ERROR**
Cartridge not ready 1". This indicates
that banks 5—8are set up to use the
VOICE MEMORY CARTRIDGE data.
*When it is necessary to change the
internal VOICE MEMORY data use the
VOICE MEMORY and bank switches to
select the desired voice data.
*Internal PERFORMANCE MEMORY data cannot
be called during PERFORMANCE MEMORY
CARTRIDGE access. The cartridge M
switch must be turned OFF in order to"
call the internal PERFORMANCE MEMORY.
*If the PERFORMANCE MEMORY CARTRIDGE is
removed while it is being accessed,
and the internal PERFORMANCE MEMORY is
selected, an error will result and
data may be lost.
3-3 STORE/MOVING MEMORY
The DXl permits changing the positions of
the PERFORMANCE MEMORY and VOICE MEMORY,
The combined preset voices in channels Aand
Bcan be selected and re-stored in the
PERFORMANCE MEMORY as required.
*The memory protect function is
automatically turned on when the DXl
power is turned on in order to prevent
accidental erasure of the internal
memory. The memory protect function
must be turned OFF in order to change
locations of either the PERFORMAiJCE or^
VOICE MEMORY. i
*When PERFORMANCE or VOICE MEMORY is
moved to anew position, the data that
was originally in that position is
erased. The position from which the
data has been moved, however, still
contains the original data. To

CHAPTER 4
EDIT mcxte/VOICE PARAMETERS
In the EDIT mode, the VOICE MEMORY voice
parameter data can be read into the VOICE
EDIT BUFFER and edited. The vast number of
parameters that can be edited permits
extremely broad-ranging voice creation.
After editing, the new data can be re-stored
in the VOICE MEMORY,
4-1 The EDIT mode
(1) The EDIT process
In the EDIT mode, the many voice parameters
in the VOICE MEMORY are read into abuffer
and edited. Since the DXl PERFORMANCE MEMORY
settings are apart of the voice created, the
PERFORMANCE MEMORY will also be involved in
the editing process. The following two
variations on the editing process are
possible:
(I) The VOICE MEMORY for aspecific voice
is altered without changing the PERFORMANCE
MEMORY.
(II) Both the edited VOICE MEMORY and
PERFORMAl^CE MEMORY are re- stored as anew
voice.
*I:
Editing the VOICE MEMORY without changing
the PERFORMANCE MEMORY.

*II:
Re-storing both the edited VOICE MEMORY
and the PERFORMANCE MEMORY as anew
voice.

(2) EDIT mode selection/Loading the buffer
*I: PERFORMANCE MEMORY selection
(fig. 20)
This is for the case in which the VOICE
MEMORY data is edited and re-stored while the
PERF0Rf4ANCE MEMORY is left unchanged.
(a) Turn all mode selectors (EDIT,
FUNCTION, STORE) OFF.
*It does not matter if the EDIT switch is
flashing,
*To edit RAM CARTRIDGE VOICES, first turn
the cartridge memory protect OFF, then
insert the cartridge into the cartridge
slot.
*After editing data from aROM cartridge,
the new voice can not be written back
into the same cartridge,
(b) Select the PERFORMANCE MEMORY position
to be edited.
*The PERFORMANCE MEMORY can not be
re-selected once the EDIT mode is
entered.
*II; VOICE MEMORY selection (fig. 21)
This is for the case in which both the
edited VOICE MEMORY and PERFORMANCE MEMORY
are re-stored as anew voice.
(a) Turn all mode selectors (EDIT, A
FUNCTION, STORE) OFF,
*It does not matter if the EDIT switch is
flashing.
*To edit ROM cartridge voice data, first
set the switch on the cartridge to the
appropriate bank, insert the cartridge
in the cartridge slot and press the
CARTRIDGE switch.
*To edit RAM cartridge voice data and
store the results in the same
cartridge, first turn the cartridge
MEMORY PROTECT switch OFF, insert the
cartridge into the cartridge slot, then
press the CARTRIDGE switch,
*To edit RAM cartridge voice data and
store the results in the internal
memory, insert the cartridge into the
cartridge slot with the MEMORY PROTECT
switch ON, then press the CARTRIDGE
switch.
*If aPERFORMANCE MEMORY CARTRIDGE is
inserted, the error message "**ERROR**
Cartridge format conflict" will be ^^
displayed when the CARTRIDGE switch id9
pressed,
(b) Select the VOICE MEMORY to be edited,
*The selected VOICE MEMORY can not be
changed once the EDIT mode has been
entered.

(3) Sv/itchintj to the EDIT mode and Entering
Data (Fig, 22)
{c) Enter the EDIT mode using the
EDIT/COMPARE switch. This makes it
possible to alter the data in the EDIT
BUFFER.
(d) The VOICE MEMORY channel will
automatically be selected/ and the
target EDIT voice indicator will flash.
*If the KEY ASSIGN MODE switch is set to
DU/iLr sound will be output from both
channels Aand B, In order to monitor
only the target EDIT voice, set the
BALANCE slide control all the way to
the corresponding channel.
(e) The LED and LCD displays display the
data for the target voice,
*The leftmost operator select switch
determines which individual operator
data is displayed.
*The LED display displays the data for
the parameter shown belov7 it.
*The LCD display shows the data of
.parameter selected by the PERFORMANCE
fMEMORY/FUNCTION switch.
(f) Select the parameter to be edited
using the row of voice parameter
switches below the LED display, or the
PERFORI-iAlXE liEnORY/FUNCTION switches.
*The voice parameter switches include
most of the FK tone generator and
operator functions that are essential
for voice creation. -*p.27
*The PERFORM/J^ICE MEMORY/FUNCTION switches
include LFO modulation-related effects
that affect all operators
simultaneoulsy. ~*p.27
*Envelope generator voice parameter Rl is
automatically selected. Simply press
the appropriate switch to select
another parameter,
(g) Set the desired data value using the
DATA ENTRY section.
*Data can also be set by continuously
pressing the selected (flashing)
PARAMETER switch.
*Use the COMPARE switch to compare the
sound of the edited data v;ith the sound
of the original data. -»a^
(h) To set the parameters for each
operator, use the OPERATOR SELECT
switches to select the operator to be
worked on. ^p.21
*Using the OPERATOR ON/OFF switches it is
possible to concentrate on asingle
operator, permitting extremely fine
sound control, -^p.22
(i) After editing on one channel has been
completed, switch over to the other
channel and perform any necessary
editing on that channel. Either
channel can be selected by pressing a
bank or voice switch of the channel you
wish to select.
*Also set the balance slider all the way
to the appropriate channel.
(4) Storing Edit Data
In order to store edit data, astore
operation must be performed. Two processes
are possible: (1) Storing data without
changing the memory position, and (II),
storing data in anew VOICE MEMORY or
PERFORMANCE MEMORY position.
*Each time power to the DXl is turned on,
the internal memory protect system is
activated in order to prevent
accidental memory erasure. This
function must be turned off in order to
perform astore operation.
*VJhen astore operation is performed,
data originally in the memory to which
the store is performed will be erased.
Data which needs to be saved should
therefore be stored in an external RAM
cartridge, -/»4ff
*In order to store edit data on an
external cartridge, acartridge
formatted for VOICE MEMORY storage must
be used. Acatridge formtted for
PERFORMANCE MEMORY cannot be used.

*I: Replacing an Original VOICE MEMORY
(fig. 23)
In order to re-store edited data in tVie
original memory locationr use the STORE ALL
function (the VOICE MEMORY and PERFORMAi-TCE
MEMORY are simultaneoulsy re-stored in their
original locations),
*Using the STORE ALL function it is
not possible to move data to another
memory location, move data from one
channel to another, or move data from
the internal memory to an external
cartridge.
*The STORE ALL function makes it possible
to store internal VOICE MEMORY data
back into the same internal memory
location, or to store cartridge memory
data back into the same cartridge
memory location. ^P.53
(j) In order to defeat the memory protect
function, switch to the FUNCTION mode,
(k) Call the protect memory write
function.
(1) When the LCD display reads "Internal
memory write protect ON", press the
DATA ENTRY NO key, causing the display
to read "Internal memory write protect
OFF". This defeats the memory protect
function.
*If you attempt astore operation with
the memory write protect function ON,
the "**ERROR** IV-protectedl "message
will be displayed and storing will not
be possible.
*The STORE VOICE function can be used if
PERFORMAI>ICE MEMORY data has not been
changed.
(m) If the store switch is used to enter
the STORE mode, the "STORE ALL FROM >>
CURRENT EDITING TO >> CURRENT SELECTED"
message will be displayed. VJith the
STORE ALL function the store position
selection process is greatly shortened.
(n) Press the DATA ENTRY YES button to
begin the store operation.
*Both channels Aand Dcannot be stored
at the same time. The store operation
must be performed on one channel at a
time,
*After the store operation be sure to
turn the VOICE MEMORY or RAH cartridge
memory protect function back on.

function (the store function which permits
movin9 VOICE MEMORY data to anew memory
location) is used. In addition the STORE
PERF0RI:A1jCE function must be used. The STORE
PERFORMANCE function is the function which
permits movinc; PERFORMANCE MEMORY data to a
new memory location.
*To store to anew position in aRAM
cartridge, or to store from aROM or
RAM cartridge to the internal memory
(single load) insert the cartridge into
the DXl and press the CARTRIDGE switch.
*If aPERFORMANCE MEMORY CARTRIDGE is
used the "**ERROR** Cartridge format
conflict!" message will be displayed
when the CARTRIDGE switch is pressed.
