(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.

Program (YRM 103)" cartridge.
Setup 2 (Large Setup)
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
Patch 3 234567% х
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.
NOTE:
The "Connection Chart" can be found on p. 18. Please photocopy it, so that you are
able to see your patch connections at a glance.

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.
