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.
