(1) Use a "Music Composer II (YRM 501)" cartridge to compose your music. Data are
input via the DX7's keyboard. Playback is achieved via DX7, TX7 and SFG Sound
Synthesizer Unit. RX11 is clocked by Music Computer.
(2) Choose Connection Setting (2) to play DX7 and TX7 manually (TX function memory
controls DX functions), while RX is clocked by CX (sound also comes from SFG).
With the "MIDI-Recorder (YRM 301)" cartridge however, you are able to record in
real time, which contributes to the liveliness of your recording.

In this setup the ТХ81 6 module numbers 2, 3 and 4, 5 are combined. ВХ is directly connected
to "Common THRU" terminal of TX816. The KX88 functions as master keyboard, either
inputting data into QX1 or controlling TX816 and DX5 (if desired, DX5 may be used as
master keyboard). See following Connection Setting examples.

With this Connection Setting, the KX88 MIDI Master Keyboard controls TX816, thus taking
full advantage of your versatile system (especially suited for live performance). All modules
can be switched to "Common" situation only by choosing this Connection Setting, even
if TX816 is located in remote position.
On top of that, the RX11 sounds are accessible via TX816's "Common THRU" terminal.

Patch 2 3456781*
KX88 serves to input recording data into QX1 tracks 1 —6 which control respectively modules
1-8 (2, 3 and 4, 5 are combined). RX11 is clocked by QX1, or can be triggered by KX88.
OUTPUT 12345678

DX5 triggers module 1 of TX816, at the same time, QX1 tracks 1-5 trigger modules 2, 3
(combined), 4, 5 (combined), 6, 7, and 8 of TX816. RX11 is synchronized with QX1. This
Connection Setting enables you to add a human touch to your sequenced track, or to perform
on your own. If desired, any track of QX1 can be assigned to send MIDI signals to Common
MIDI IN Terminal, and any module of TX816 can receive those MIDI signals if it is set to
Common MIDI Input.

SPECIAL MESSAGE SECTION
ELECTROMAGNETIC INTERFERENCE (АРІ): Your Yamaha
Digital Musica! Instrument Product has been type tested and
found to comply with all applicable regulations. However,
if itis installed in the immediate proximity of other electronic
devices, some form of interference may occur. For additional
RFI information see FCC information section located in this
manual.
IMPORTANT NOTICE: This product has been tested and
approved by independentsafety testing laboratories in order
that you may be sure that when it is properly installed and
used in its normal and customary manner, all foreseeable
risks have been eliminated. DO NOT modify this unit or
commission others to do so unless specifically authorized
by Yamaha. Product performance and/or safety standards
may be diminished. Claims filed under the expressed war-
ranty may be denied if the unitis/has been modified. Implied
warranties may also be affected.
SPECIFICATIONS SUBJECT TO CHANGE: The information
contained in this manual is believed to be correct at the time
of printing. Yamaha reserves the right to change or modify
specifications at any time without notice or obligation to
update existing units.
NOTICE: Service charges incurred due to a lack of know-
ledge relating to how a function or effect works (when the
unit is operating as designed), are not covered by the
manufacturer's warranty. Please study this manual carefully
before requesting service.
NAME PLATE LOCATION: The graphic below indicates the
location of the Name Plate on your Yamaha Digital Musical
Instrument. The Model, Serial Number, Power requirements,
etc., are indicated on this plate. You should note the model,
serial number and the date of purchase in the spaces pro-
vided below and retain this manual as a permanent record
of your purchase.
STATIC ELECTRICITY CAUTION: Some Yamaha Digital
Musical Instrument products have modules that plug into the
unit to perform various functions. The contents of a plug-in
module can be altered/damaged by static electricity dis-
charges. Static electricity build-ups are more likely to occur
during cold winter months (or in areas with very dry cli-
mates) when the natural humidity is low. To avoid possible
damage to the plug-in module, touch any metal object (a
metal desk lamp, a door knob, etc.) before handling the
module. If static electricity is a problem in your area, you
may want to have your carpet treated with a substance that
reduces static electricity build-up. See your local carpet
retailer for professional advice that relates to your specific
situation.

FCC INFORMATION
While the following statements are provided to comply
with FCC Regulations in the United States, the cor-
rective measures listed below are applicable world-
wide.
This series of Yamaha professional music equipment
uses frequencies that appear in the radio frequency
range and if installed in the immediate proximity of
some types of audio or video devices (within three
meters), interference may occur. This series of Yamaha
combo equipment have been type tested and found
to comply with the specifications set for a class B
computing device in accordance with those specifi-
cations listed in subpart J of part 15 of the FCC rules.
These rules are designed to provide a reasonable
measure of protection against such interference.
However, this does not guarantee that interference
will not occur. If your professional music equipment
Should be suspected of causing interference with other
electronic devices, verification can be made by turning
your combo equipment off and on. If the interference
continues when your equipment is off, the equipment
is not the source of interference. № your equipment
does appear to be the source of the interference, you
should try to correct the situation by using one or
more of the following measures:
Relocate either the equipment or the electronic device
that is being affected by the interference. Utilize power
outlets for the professional music equipment and the
device being affected that are on different branch
(circuit breaker or fuse) circuits, or install AC line
filters.
In the case of radio or TV interference, relocate the
antenna or, if the antenna lead-in is 300 ohm ribbon
lead, change the lead-in to co-axial type cable.
If these corrective measures do not produce satisfac-
tory results, please contact your authorized Yamaha
professional products dealer for suggestions and/or
corrective measures.
If you cannot locate a franchised Yamaha professional
products dealer in your general area contact the
Electronic Service Department, Yamaha Music Cor-
poration, 6600 Orangethorpe Ave., Buena Park, CA
90620, U.S.A.
If for any reason, you should need additional infor-
mation relating to radio or TV interference, you may
find a booklet prepared by the Federal Communi-
cations Commission helpful:
“How to Identify and Resolve Radio — TV Interference
Problems”. This booklet is available from the U.S.
