INTRODUCTION
Thank you for purchasing the Yamaha TX802 FM Tone Generator. The TX802
contains 8independent tone generators in acompact two-space rack-mountable
case, and can produce up to 16-note polyphony. It uses the same sound-producing
circuitry as the DX7II synthesizer and can use voice data created for the popular
DX7 synthesizer.
The sheet of Quick Playing Instructions included with the TX802 will tell you
how to try out the Performance and Voice memories. When you are ready to learn
more, read through this manual page by page.
This manual assumes you know something about MIDI, the world-wide stan-
dard interface for digital musical instruments. Supplementary material explaining
MIDI is available from Yamaha.

FEA TURES
*Eight independent tone generators, each with an individual audio output.
*Tone generators can be linked together to play chords of up to 16 notes.
*Voice data and all memory parameters can be edited from the front panel. No separate programming
device or computer is necessary.
*Each of the 8tone generators uses the same LSI as the DX7II synthesizer, producing especially clear and
powerful FM sounds.
*128 factory preset voices in ROM.
*64 user-programmable voice memories.
*64 user-programmable performance memories.
*Microtonal Scales.
*Fractional Scaling for precise voicing.
*Controller Assign Table allows incoming MIDI Control messages to be reassigned.
*Cartridge interface for quick external data storage. (ROM and RAM cartridges are not included.)
*Large 40-character two-line illuminated LCD.
*Front panel ten-key pad for speedy memory selection and data entry.
*Handy tilt stand is attached underneath for aconvenient operating angle when the unit is placed on a
table.
PRECAUTIONS
*Avoid placing the unit in direct sunlight or close to asource of heat. Also, avoid locations where the unit is
likely to be subjected to vibration, excessive dust, cold or moisture.
*Avoid applying excessive force to the switches, dropping or rough handling. While the internal circuitry is of
reliable integrated circuit design, the unit should be treated with care.
*Always grip the plug directly when removing it from an AC receptacle. Removing the plug from the AC
receptacle by pulling the cord can result in damage to the cord and possibly ashort circuit. It is also agood
idea to disconnect the unit from the AC receptacle if you don't plan to use it for an extended period of time.
*If necessary, clean the unit using aslightly damp cloth, and dry with asoft cloth. Never use solvents (such as
benzine or thinner) since they can melt or discolor the finish.
*All computer circuitry, including that in this unit is sensitive to voltage spikes. For this reason, the unit should
be turned off and unplugged from the AC receptacle in the event of an electrical storm. This precaution will
avoid the chance that ahigh voltage spike caused by lightning will damage the unit.
*Computer circuitry is also sensitive to electromagnetic radiation. Be careful not to set it too close to equip-
ment (such as atelevision set) that generates electromagnetic fields. Proximity to such equipment could
cause malfunctions in the TX802's digital circuitry and interfere with the operation of the other unit.
*When inserting acartridge in the cartridge slot, make sure it is facing the correct way, and do not use
excessive force.
*This unit contains no user servicable parts. Opening it or tampering with it can lead to electrical shock as well
as damage, and will void the product warranty. Refer all servicing to qualified Yamaha personnel.

PERFORMANCE SELECT
PERFORMANCE SELECT
You will normally play the TX802 in this mode. The TX802 contains 8tone generators, each with its own rear
panel audio output. Each tone generator can be set to a different voice and MIDI channel, and played as an
independent instrument with up to 2simultaneous notes. Or several tone generators can be linked together to
form an instrument with 4-16 note polyphony.
Acombination of settings for these 8tone generators is called aPerformance, There are 64 performance
memories inside the TX802, and you can store another 64 in acartridge.
The Performance Number and Name are displayed in the upper line of the LCD. The lower line shows the
voice numbers used. Long arrows '\—"to the right of avoice number means that tone generators have been
Linked (p. 7) to form an instrument of 4-16 note polyphony. Short arrows "f "between voice numbers indi-
cate that these voices are Alternately Assigned {p. 15), and sucessive notes will alternately play each voice.

6. Initialize
Table
The Control Number table (p. 8) allows you to redefine incoming MIDI control
messages. The Performance Select table (p.9) allows you to set which Perfor-
mance memory is selected by which incoming MIDI Program Change
message. This Initialize Table function lets you to initialize either of these
tables to its standard setting. Press PARAMETER SELECT 6to select the Con-
trol Number or Program Change table and press YES. You will be asked "Are
you sure?" so press YES again.
7. Recall Edit
Buffer
If while editing you accidently select aPerformance or Voice and wipe out the
edited data, you can use this function to recall the data to the edit buffer.
Press PARAMETER SELECT 7to select the Performance or Voice edit buffer
and press YES. You will be asked "Are you sure?" so press YES again. The
previously edited data will be recalled.
8. Copy When editing voice data (p. 18) it is often useful to copy the EG or oscillator
settings of one operator to another. You have three ways to copy data. Press
PARAMETER SELECT 8to select the operator data you want to copy.
EG and Scaling
EG parameters, Rate Scaling, Level Scaling parameters.
Oscillator
Oscillator Mode, Frequency, Detune.
Operator
All operator parameters (The above two and Velocity and AMS.)
Select the source and destination by moving the blinking cursor to the opera-
tor number, using the ten-key pad to set the operator number and pressing
ENTER. When the source and destination are set correctly, press YES. You will
be asked "Are you sure?" so press YES again. The data will be copied from
operator to operator.

The Performance
Ed/t Buffer
When you select aPerformance Memory, the data is loaded into aplace called
the Performance Edit Buffer, and this data tells the TX802 how to behave.
Changes you make in PERFORMANCE EDIT mode affect only this buffer, and
are not permanent until Stored into an Internal or Cartridge Performance
Memory. (See Store p. 6). Once aPerformance has been edited, the LCD in
PERFORMANCE SELECT mode (p.6) will show "int" or "crt" in lower-case let-
ters, indicating that the performance data has been modified.
^
Compare Any time you are editing aperformance, you can press COMPARE to see and
hear the original performance data. In COMPARE mode, all parameters in the
LCD will blink, and you will not be able to modify the data. Look through the
parameters just as in normal edit mode. To return to edit mode, press COM-
PARE again.
Linked Tone
Generators
When two or more tone generators have been linked together (p. 7) to form an
instrument with 4or more notes, the LCD will show an arrow "«—"for that
instrument, and its data will not be displayed.

7. Receive
Channel/
Alternate
Assign/
Forced Damp
(1-16, omni)
Messages on this MIDI channel will be received by this instrument. If you set
"omni", messages on any channel will be accepted. See also SYSTEM SETUP
MIDI Receive (p.8).
Program Change messages on this channel will select voices for this
instrument UNLESS this channel has been specified as the Performance
Memory Select channel (p.9) or Program Change message reception has been
switched off (p.8).
When adjacent instruments are receiving the same MIDI channel, they can
be set to Alternate Assign. Press ENTER + ON and ashort arrow "<- "will
appear to the left of the channel number, indicating that the instrument is in
Alternate Assign mode. In this mode, each incoming note will rotate between
the alternately assigned instruments. If three instruments playing Strings,
Brass and Piano were set to Alternate Assign, athree-note chord would
include one note of each voice. (However, by switching each instrument in and
out of Altermate Assign mode in random order, it is possible to confuse the
assignment scheme so that athree-note chord may be sounded as 2, 1,0
instead of 1, 1, 1.)
Press PARAMETER SELECT 1again to get the EG Forced Damp display.
When you play more simultaneous notes than an instrument can produce, the
oldest note will stop sounding in order to "make room" for the new note.
When EG Forced Damp is off, the envelope of the new note will be acontinua-
tion of the note that has stopped sounding. When EG Forced Damp is on, the
envelope of the old note will quickly drop to 0, and the new note will start its
envelope from the beginning.

2. Volume (0-99)
The volume of each instrument can be set from to 99. When aperformance
is first selected, the instruments will be set to the indicated volumes. MIDI
Volume control messages (Bn.07.xx) will affect all instruments evenly to
preserve the "balance" set here.

3. Output
Assign
(off, I, II, III)
Each instrument can be sent from neither, either, or both of the programmable
outputs Iand II. No matter what this setting is, the signal from each tone
generator is always sent from its own individual audio output —this cannot
be switched off. Even when two or more tone generators are linked (p. )to
make a4-16 note polyphonic instrument, the notes will be spread over the
individual outputs. Thus, when using linked tone generators, it is probably
easier to use the Assignable Outputs Iand II, which assign all the linked tone
generators of an instrument together.
The individual outputs are useful when you need independent EQ, pan-
ning and effects on each instrument, for example when using the TX802 as a
percussion tone generator with the PMC1 Percussion MIDI Controller or the
RX Rhythm Programmer.
4. Low/High
Limit
Midi Note
Shift
(C-2 -G8)
High and Low limits can be set for each instrument. Incoming notes falling out-
side of these limits will not be played. Using this, you can create split keyboard
effects using just one MIDI channel.
Instruments set to Alternate Assign (p.1 5) will all use the Low/High limits
of the left-most instrument.
(-24 -+24)
The incoming MIDI Note On message can be transposed up or down for a
maximum of two octaves. However, the resulting "note number" cannot fall
outside the MIDI note range of 0-1 27. Midi Note is independent of the voice
parameter Transpose (p.1 9), and the two will be added together to determine
the note actually sounded.

Each instrument can use adifferent tuning; you can choose from the 11inter-
nal presets, the 2internal user tunings, or 63 user tunings from acartridge.
Move the cursor to an instrument and use the +1/-1 keys to select atuning
for that instrument. When there is achoice of key (P02 -P05), move the
special cursor on the upper line to the key (ENTER +CURSOR) and select
using +1/-1. When "Internal" or "Cartridge" is displayed, move the special
cursor on the upper line in the same way and select 101/102 or C02-C63. ^

PERFORMANCE EDIT
The "normal" setting is P01 Equal Temperament. If you have selected a
cartridge tuning but acartridge is not inserted P01 will be used.
If you have modified atuning using SYSTEM 6>Micro Tune Edit (p.9),
the bank name (P, I, C) will be shown in lowercase letters (p, i, c).
For the tuning details of scales P01 to P08 see the data table on p.28.
P09 1/4 Shifted Equal Temperament is the normal scale shifted up 50 cents.
When P10 1/4 Tone is used, the interval between each key is 50 cents (ie.
play 24 keys to move one octave). When P1 11/8 Tone is used, the interval
between each key is 25 cents (ie. play 48 keys to move one octave.)

7. Performance Each instrument can be detuned independently. Two instruments playing the
Detune same voice in unison can be detuned to create arich sound.
Each performance memory can be given a20-character name. Use the ten-

In this section we assume you already know something about FM synthesis. If not, turn to p. 24 and read
"What's FM?" before continuing.
VOICE EDIT (I) is where you edit the parameters that determine how avoice sounds; ie. the FM synthesis
parameters. When you press VOICE EDIT (I) you will get the following display. Press the PARAMETER SELECT
keys 1-8 to select the parameters displayed in the lower line.

The Voice
Edit Buffer
When you select aPerformance Memory, voice data for each instrument in the
performance is loaded into aplace called the Voice Edit Buffer, and this data
tells the TX802 how to produce sound. There is aseparate Voice Edit Buffer
for each instrument 1-8. Changes you make in VOICE EDIT mode affect only
these buffers, and are not permanent unit Stored into an Internal or Cartridge
Voice Memory. {See Store p.7). Once avoice has been edited, the LCD in PER-
FORMANCE SELECT or VOICE SELECT mode will show the voice bank in
lower-case letters (e.g. i64 or a45), indicating that the voice data has been
modified.
Compare Any time you are editing avoice, you can press COMPARE to see and hear the
original voice data. In COMPARE mode, the lower line of the LCD will blink,
and you will not be able to modify the data. Lock through the parameters just
as in normal edit mode. To return to edit mode, press COMPARE again.
/. Operator
Select &
On/Off
Most of the parameters 2-6 in VOICE EDIT (I) can be set independently for
each operator. Step through the operators by pressing PARAMETER SELECT
1.When editing, it is often useful to hear only acertain combination of opera-
tors at once. By pressing ENTER +ten-key 1-6, you can turn each operator on
or off. The "111111" at the left indicates which operators are on (1 )or off
(0). If an operator is turned off you will not be able to edit it. Obviously, if all
carriers are turned off, there will be no sound.
