Welcome
Welcome to the DX7s, the newest member of the growing family of FM digital
synthesizers from Yamaha. Using the industry-standard DX7 as its starting point, the
DX7s offers a number of important new features, such as improved sound quality,
additional FM features, new performance options, and improved controls.
Since there is so much material available on the DX7 family of synthesizers (and on the
theory of FM digital synthesis), this manual will not be an FM tutorial. Instead, it has
been designed to be a “users manual” in the truest sense — its goal is to help you make
music with your new DX7s as quickly as possible.
If you are already familiar with the operation of the original DX7, this manual will help
you make the transition to the DX7s in short order. On the other hand, if this is your first
FM digital instrument, this manual will guide you into the operation of your new
synthesizer with easy-to-follow, step-by-step instructions and explanations.
After you are comfortable with the operation of your new synthesizer, you may want to
explore the fascinating world of FM digital voicing. If so, consult the extensive list of
reference works on FM synthesis listed in the bibliography at the back of this manual.
Tips
The DX7s has been designed for years of trouhle-free use. In order to ensure that it
remains a healthy member of your family
following tips in mind:
of
musical instruments, please keep the
Installation:
When setting up the DX7s in your home or studio, avoid exposure to direct sunlight or
other sources of heat. Environments with excessive dust, cold, dampness, or vibration can
also damage your instrument. Even though the DX7s is electronic, you should treat it with
the same kind of care you would lavish on any other musical instrument.
Also, since the DX7s is electronic, you should make sure not to set it too close to
equipment (such as a television set) that generates electromagnetic fields. Such proximity
could cause both malfunctions in the synthesizer’s digital circuitry and interference noise
in the other unit.
Handling:
The DX7s is sturdy, but it can do without rough handling. Don’t subject it to sudden jolts
(such as dropping it), as this can damage the internal circuitry. If you plan to travel with it,
be sure to use a road case. Also, make sure not to apply excessive force to any of the keys,
buttons, or other controls.
Cleaning:
To clean or dust your DX7s, use nothing more than a clean, slightly damp cloth. Using
chemical solvents will damage the finish, and using too much water may do considerable
damage to the internal circuitry.
AC Power & Other Equipment:
When you are using the DX7s with an amplifier or mixer that has unbalanced outputs,
connect both units to the same AC outlet to avoid hum.
If you use a number of electronic instruments in your setup, you may want to consult an
electrician, who can make sure that your system does not overtax the available power.
AC Power & Down Time:
Whenever the DX7s will not be used for an extended period of time, it is best to protect it
from potential disaster. Electrical storms and other natural or man-made disasters can give
rise to power surges, which may damage the digital circuitry of your DX7s — even if the
power is turned off. Either unplug your instrument when not in use, or invest in power
strips with surge protectors to safeguard all of your electronic equipment.
Service & Your Warranty:
The DX7s contains no user-serviceable parts. Opening it up or tampering with it in any
way will void the warranty, and may also lead you to experience some nasty electrical
shocks. If you have a problem with your instrument, please take it to an authorized
Yamaha service center.
Modifications & Your Warranty:
Unless you are assured to the contrary in writing, you should assume that any
modifications made to your DX7s will void the original product warranty. Therefore, you
should make sure that you receive a warranty (or some other kind of guarantee) from the
person or company that is responsible for the modification.

You can begin to enjoy your DX 7s immediately, without poring through a lot of
complicated electronic theory. A ll you have to do is take the instrument out of the box and
proceed as follows:
Making Audio Connections
There are three different ways to connect the DX7s to sound reinforcement equipment.
The one you choose will depend on your situation:
you

Banks
The ROM Cartridge supplied with your DX 7s actually contains several sets of data —
called “ banks.” These banks can be selected from the front panel. In order to hear all of
the Voice and Performance data, you will need to set the Voice/Performance bank to 2.
Also, certain voices in the DX7s are created using the new fractional scaling feature.
These scalings are stored in bank 3 of the ROM cartridge, so the Fractional Scaling Bank
will need to be set to bank 3. Look at the diagram on the next page and make the
necessary changes before you begin playing.
Inserting the ROM Cartridge
Before you begin to play your DX7s, insert the supplied ROM cartridge into the cartridge
slot:

useful performance-oriented features to be stored and recalled instantly. These features
will be explained in detail in Sections 2 and
the steps below, and explore the richness of the Performance Mode by playing through all
of the new sounds available in the Internal and ROM Cartridge memories.
As explained on page 6, the DX7s ROM cartridge contains several banks. To hear the

The Play Modes
Now that you have an idea of some
a closer look at how the various Play M odes operate. Read on:
Voice Mode and Performance Mode
The DX7s has two different play modes: Voice Mode and Performance Mode. As you
have just seen, the Voice Mode is where you recall the 64 Internal Voice memories and
the 64 Cartridge Voice memories. Press Voice and use the 1 ~ 32/33 ~ 64 button and the
program number buttons to select specific voices. There are 32 Performance memories
that you can access by pressing Performance and the program number buttons. When you
are in Performance Mode, the light over the Performance button will be lit. When you
choose a Performance, features such as Micro Tune and Key Shift are added to the voice.
Using the 1 ~ 32/33 ~ 64 Button
The light above the 1 ~ 32/33 ~ 64 button tells you which set of voices can be selected. If
the light is off, voices 1 ~ 32 can be selected using the number buttons; if the light is lit,
voices 33 ~ 64 can be selected using the number buttons.
Using the Poly/Mono Button
The light above the Poly/Mono tells you which Key Mode is currently active in Play
Mode. If the light is off, the Key Mode is polyphonic; if the light is lit, the Key Mode is
monophonic. Key Modes will be explained further in Section 4.

the DX7s, it is time to take
Using the Key Shift Button
The Key Shift button determines whether the key shift programmed in Performance Mode
will be applied when you recall the Performance. If the light above Key Shift is off, no
key shift will be applied; if the light is lit, the preprogrammed key shift is applied.
- 16 -
Using
Controllers
with the DX7s
The DX7s is designed to operate with many controllers, each of which can be set to
perform one of a number of different effects. The settings for these controllers can be
different for each Voice memory or Performance memory. To begin your exploration of
the expanded musical possibilities available with controllers on the DX7s, try the
examples listed below. Many of you may already be familiar with the operation of the
these controller’s; for those who are not, each section below begins with instructions on
how to locate or attach the controller in question.
Pitch Bend Wheel
The Pitch Bend Wheel is located to the far left of the keyboard. To get an idea of some of
the effects possible with the Pitch Bend Wheel, use it with Internal Performance #1 or
Internal Performance #31. Move the Wheel both quickly and slowly as you play.
Modulation Wheel
The Modulation Wheel is located to the near left of the keyboard (to the right of the Pitch
Bend Wheel). For a taste of the possibilities of the Modulation Wheel, try it with Internal
Performance #6 or Internal Performance #13.
After Touch
After Touch is a keyboard feature that gives you extra control over a voice. It is engaged
by pushing down on the keys after they have already been depressed. To try some of the
effects available with After Touch, call up Cartridge Performance #4 or Cartridge
Performance #5 (from bank 2 of the ROM). After you have played a group of keys, press
them down into the key bed and listen to the result.
Breath Controller
The Breath Controller plugs into the mini-jack to the left of the Phones plug on the front
of the DX7s. It allows you a great deal of expressive control over the shape of the sounds
you play on the keyboard. Try using the Breath Controller in conjunction with Internal
Voice #9. With this voice, you will notice that playing on the keyboard by itself produces
no sound. In order to hear the voices, you must hold down keys and blow into the Breath
Controller.
- 17 -
Foot Controllers 1 and 2
The Foot Controllers plug into the two Foot Controller plugs on the back panel of the
DX7s. They can give you continuous control over a number of aspects of the sounds. Try
using Foot Controller 1 with Cartridge Performance #25 or Internal Performance #12
(from bank 2 of the ROM). Foot Controller 2 is most often used as a volume pedal, but
other effects are possible.
Footswitches 1 and 2
The Footswitches plug into the two Footswitch plugs on the back panel of the DX7s.
Footswitch 1 acts much like a sustain pedal on a piano. Try it with Internal Performance
#19 or Cartridge Performance #5 to get an idea of the different effects that are possible.
Footswitch 2 can be used to engage a number of effects, including that of the soft pedal on
a piano. Try it in conjunction with Internal Performance #4 or Cartridge Performance #8
(from bank 2 of the ROM).
Continuous Sliders 1 and 2
The Continuous Sliders are located to the right of the Volume Slider on the left side of the
DX’s front panel. They can be programmed to give you control over many aspects of the
timbre of the sounds, and can even be used to alter parameters of a voice in real time. Try
using Continuous Slider 1 with Internal Performance #8 or Cartridge Performance #3.
Then listen to the effect that Continuous Slider 2 has on Internal Performance #3 or
Cartridge Performance #24.

(edited) to create new Voice and Performance setups. To find out how this works, read on.
Editing and Edit Mode
Editing is the process of changing various settings of a Voice or Performance memory. In
the DX7s, this is accomplished in Edit Mode. Usually, you will use Edit Mode to create a
new Voice or Performance setup, but you can also use it to find out the parameter values
for the factory preset Voices and Performance setups.
Most of the buttons on the DX’s front panel have multiple functions. You can see this by
looking at the way the buttons are labeled on the front panel. For example, the +1 button
also functions as YES and ON. In most cases, the buttons will have different functions in
different operating modes.
The 32 number buttons are no exception: In the Play Modes, they are used to call up
various Voice and Performance memories; but, in the Edit Modes, they are used to access
the various parameter values that make up a sound.
Normally, when you enter the voice play mode (by pressing the voice button), the
performance parameters will automatically be initialized. If you then go into the
performance play mode (by pressing the performance button) the LCD display will show
you this by displaying “INIT PERF”.

parameters.
Entering Edit Mode
In the above procedure, the Edit Mode is entered after the Edit button is pressed in step
#1. At that time, you can push any or all of the buttons indicated as many times as
necessary to make the desired edits.
There is a distinction between editing Performance parameters and editing Voice
parameters that you may want to be aware of. In certain cases, (such as using compare)
you may not retain all your edits. It is a good idea to edit Performance and Voice data
separately (more on this later).
- 22 -
Editing Performance and Voice Data
After entering one of the Edit Modes, use the number buttons to access the parameter
whose value you wish to change. Each number button calls up a variety of parameters,
often through the use of multiple LCD screen displays. A complete set of these screen
displays will be given at the beginning of Section 3 (for Performance parameters) and
Section 4 (for Voice parameters). In most cases, each LCD display gives you access to a
number of parameters.

Edit/Compare
Once you have started to edit a voice, you can compare your new sound to the original by
pressing the Edit/Compare button:
You may use the compare feature for Voice data, Performance data, or Micro Tune data. It
is best not to use compare when you are simultaneously editing more than one type of
data. For example, if you are editing Voice data, and then start editing Performance data,
using compare may cause Voice data to revert to the original.
