WARNING: Failure to follow appropriate service and safety procedures when servicing this product
may result in personal injury, destruction of expensive components and failure of the
product to perform as specified. For these reasons, we advise all Yamaha product owners
that all service required should be performed by an authorized Yamaha Retailer or the j
appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute
authorization, certification, recognition of any applicable technical capabilities, or
|establish aprinciple-agent relationship of any form, ;
jThe data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The

HOW TO USE THE TX7
1. What is the TX7?
The TX7 is atone generator module that can be controlled
by MIDI signals from the DX series, QX1 ,CX5 etc. It is
the equivalent of the DX7 tone generating section.
When connected to aDX7 or DX9, it can act as afunction
memory for the DX7 or DX9, and thus allow you to create
sounds just like aDX1
.
[Features]
•FM tone generation system.
•16 note polyphonic.
•Internal memory: 32 voice data, 32 function data,
stored in pairs. Each voice memory has its own function
memory.
•Individual volume and high and low note limits can be
set for each voice memory. Also, independently of the
voice memory, two volumes may be preset, and recalled
instantly by afront panel switch. This can be used for
muting.
•Besides the TX7's own 32 voice memories and 32 func-
tion memories, it will store 32 function memories for
the DX7. This can be used as an extended function
memory for the DX7.
2.Memory diagram and flowchart of the TX7
The internal memory structure is shown below.

;Voice edit buffer
Function edit buffer

Volume, master tune
The voice and function data of the selected memory
number is loaded into the voice and function buffers.
Then, the voice and function data is loaded into the FM
tone generator, and it is ready to produce sound.
All editing of voice and function data is done on the data in
the buffers.
When the store command is executed, the data in the
buffers is stored into the respective memories.
The data in the function edit buffer will be stored into the
memory that you designate.
3. How the switches work
There are four kinds of switches on the from panel of the
TX7. 0Switches to enter volume and data, 0Switches
that have different operations when in normal or shift
mode, ®Selector switch normat/shift mode, 0Switches
to set function data.
The operation of switches types 0^0is shown below.

When changing the other way back to program change or
store modes, press MODE switch again to change to
NORMAL mode. Then press the program change or store
mode switch.

•When you press avoice select switch on the DX7,
program change data is sent from MIDI OUT. The TX7
will load voice and function data for the selected pro-
gram number into its edit buffers 0
At the same time, the DX function data for that pro-
gram number will be sent from the TX7 MIDI OUT as
one performance bulk data (2)
•The same thing will happen if you select aprogram
number using the TX7 switches.
In this way, by using the program select switches of
either the TX7 or the DX7, you can change both func-
tion memories simultaneously, simulating the operation
of the DX1 performance memory.
2) Individual mode
•In the setup shown in diagram 3, when you press aDX7
voice select switch, program change data will be sent
from MIDI OUT.
The TX7 will send the DX function data for that pro-
gram number out of its MIDI OUT as one performance
bulk data (2)
However, the TX7 voice and function will not change,
ie 0will not occur.
•In the setup shown in diagram 3, when you change the
TX7 voice number, the TX7 will load the selected voice
and function data into its buffers 0
However, DX function data will not be sent from MIDI
OUT, ie 0will not occur.
In this way, you may select programs independently for
the TX7 and DX7, and change voice and function
memories as apair, thus expanding the possibilities of
combinations.
4. Program change mode
This is the mode to select voices. Use this mode when play-
ing the TX7. This mode has the following two choices.
•Combined mode {when power is switched on, it will be
in this mode.)
•Individual mode
Select voices using the [YES +1 3[NO -1 ]switches.
1) Combined mode
Here is adiagram showing the data flow when aDX7 is
connected to MIDI IN.OUT when the TX7 is in combined
mode.

3) Editing voices of the TX7
You may edit TX7 voices by sending the voice data from
the TX7 to an editing device (such as the DX7), editing it,
and sending the edited voice data back to the TX7.

Diagram 5
0Turn the TX7 Data Entry Receive ON. (MIDI mode)
0Set the editing device to accept TX7 voice data. (For
example, using the DX7, set the internal memory pro-
tect OFF, and set system information to AVAIL.)
0When the TX7 display shows edit voice out, press [YES
+1 ]to transmit the voice data in the edit buffer.
®Put the editing device in edit mode, and edit the voice.
This will change the data in the TX7 voice edit buffer
(one parameter at atime). At present (January 1985),
possible editing devices are DX7, DX9, DX1, YRM13.
*When in program change mode (combined mode, indi-
vidual mode), if the DX7 system information is AVAIL
and you press avoice select switch, 1voice bulk data will
be sent from MIDI OUT, and the data in the TX7 voice
edit buffer will be replaced by the new data from the
DX7.

3. Transmission data
Normally, there will be no data transmission. Data will be
transmitted when there is adump request signal from
outside, or through operation of the panel switches. The
transmitted data is voice and function system exclusive
data. Data will always be sent on channel 1
.

The contents of the TX function memo-
ries 1-32 will be sent.
f=932 voice bulk data
Voice data of programs 1-32 will be
