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.
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 of musical instruments, please keep the following tips in mind: Installation: When setting up the DX7s in your home or studio, avoid exposure to direct sunlight or other sources of heat.
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.

Bank 4 of the supplied ROM cartridge contains the Voice & Performance Memory loaded into the DXs Internal Memory when it is shipped from the factory. Bank 2 contains an entirely different set of Voice & Performance data. The Cartridge Performance Memories Performance Voice Voice Name No.
Exploring the DX7s Voice Library The voices in the DX7s were created using techniques like those used on the original DX7. There are a number of new features available in Voice Mode (mos t of them extensions of the Function Mode in the original DX7). All of these features will he discussed in detail in Sections 2 and 4 of this manual.
These are the Voice Memories loaded into the DX7s when it is shipped from the factory. Since these memories can be adjusted, your DX’s Internal Memory may contain different data. If so, reload the Internal Voice & Performance data from bank 1 of the supplied ROM cartridge (see page 70).
Selecting the Cartridge Voice Memories As explained on page 6, the DX7s ROM cartridge contains several banks. To hear the cartridge voices, make sure that the Voice/Performance bank is set to bank 2 of the ROM cartridge (see page 7 for instructions on how to change the cartridge banks).

The Play Modes Now that you have an idea of some of the sound possibilities of the DX7s, it is time to take a closer look at how the various Play Modes operate. Read on: Voice Mode and Performance Mode The DX7s has two different play modes: Voice Mode and Performance Mode.
Using Controllers with the DX7s - 17 - 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.
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).

Creating New Sounds The Voices and Performance setups in the DX7s are stored as digital information in a computer-like memory. And, like computer memory, the memory of the DX7s can be altered for different uses. In other words, voices do not exist as unchangeable presets (as they do in electronic organs), but rather as streams of data.
In the Edit Mode, you can edit both Voice and Performance 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.
The cursor buttons and the data entry slider/buttons. The Edit/Compare LED display. 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.
Voice parameters are discussed in more detail in Section 4. Voice parameters are discussed in more detail in Section 4. Edit Button Quick Reference Guide - 24 -.
Performance parameters are discussed in more detail in Section 3. Utility parameters are discussed in more detail in Section 5. MIDI parameters are discussed in more detail in Section 6.
Saving New Sounds Once you have altered a particular Voice or Performance memory to your liking, you will want to save your new data in one of the DX’s memory locations. Voice memories and Performance setups can be saved either to the Internal Memory or to a RAM Cartridge Memory.

Basic Performance Parameters Accessed using buttons 28 and 29, these parameters determine the basic voice relationships in Peformance Mode. Total Volume This parameter allows you to set an overall volume for each Performance memory.
Under normal conditions, the DX’s envelope acts this way. Using the EG Forced Damping parameter, the envelope is forced to retrigger itself for each new note played. EG Forced Damp Even though the DX7s is a 16-voice synthesizer, these voices can be used up quickly when you use a Sustain Footswitch pedal.
Since you have a total of ten characters to define your Peformance Memory, make sure that your Performance Name conveys the basic approach of the specific Performance Memory. Performance Name You can enter a Performance Name of up to ten characters. To do so, follow the instructions below.
Performance Controllers The DX7s features a greatly expanded set of controller options. The settings for Footswitches 1 and 2 and Continuous Sliders 1 and 2 are adjusted in Performance Edit Mode, using button 27. (The other controller settings are accessed in voice parameters.
The Continuous Sliders provide a new avenue for exploration of real-time timbral control. Continuous Sliders The two Continuous Sliders give you access to real-time control of FM voice parameters.

Basic Voice Editing Functions Voice editing is easier on the DX7s, thanks to the direct operator access provided by buttons 1 ~ 6 and 17 ~ 22. Operator Select The parameters accessed using buttons 8 ~ 11 are adjustable for each of the six operators. While editing Voice data, buttons 1 ~ 6 provide a quick way to move from one operator to another.
New Voice Parameters Maximum Pitch Range Change Range 1/2 6 semitones 1 1 octave 2 2 octaves 8 8 octaves Representative Pitch Enselope Generator shape. The basic voice of the DX7s is almost exactly the same as that of the ori,ginal DX7, assuring complete compatibility between the old and new instruments.
Key Modes The DX7s offers two Unison Key Modes, which create “fatter” sounds. Since these new Modes use more than one note of the DX’s sixteen-note capacity, they will affect the total number of.
Voice Controllers Pitch Bend Modes on the DX7s. The DX7s features an expanded set of controller options. The settings for Pitch Bend Wheel, Modulation Wheel, Aftertouch, Breath Controller, and Foot Controllers 1 and 2 are adjusted in Voice Edit Mode, using buttons 24 ~ 2 6 (The other controller settings are accessed in Performance Edit Mode.
Pitch Bias With the new Pitch Bias feature you can use After Touch or the Breath Controller to control the pitch of a voice. When Pitch Bias is set to 0, there is no pitch change. Positive Pitch Bias settings result in an upward bend, while negative Pitch Bias settings cause the pitch to bend down.
Fractional Scaling Fractional Scaling allows you to adjust the output level of each operator for three-note groups. Entering Fractional Scaling Edit Mode One of the most important aspects of DX7 voicing is Level Scaling, which allows adjustment of each operator’s output over the range of the keyboard.

Memory Types The chart below is a graphic representation of the way all the different DX7s memory areas interact with one another. Since there are many facets to the memory layout of the DX7s, it may look intimidating at first.
System Setup Memory System Setup Memory contains most of the basic MIDI settings. System Setup is always retained in Internal Memory, along with the Voice & Performance Memory and the two User-defined Micro Tunings. For more information on System Setup Memory, see Section 6 of this manual.
Memory Storage Types The RAM4 cartridge can be used to store one of three possible kinds of data. In addition to having a number of distinct types of memory, the DX7s offers a number of ways to store these various memories. To understand how the various memory storage possibilities interact, read on.
The supplied ROM cartridge holds a number of different kinds of DX memory. ROM Cartridge The supplied ROM cartridge contains 4 banks, which can be accessed using button 15 in Edit Mode: The first two banks are Cartridge Voice and Performance data.
Basic Utility Functions Most of the basic Internal Memory Utility functions are accessed using button 14 in Edit Mode, as follows: Master Tune This sets the tuning of the DX7s relative to its internal A-440 reference. Recall Edit These functions can be used to recall Voice, Performance, or Micro Tuning data from the DX’s Compare/Recall Memory.
Cartridge Memory Functions LCD display indicating that required Fractional Scaling or Micro Tuning data is not available. When the needed data is supplied via a RAM cartridge, these displays disappear. RAM cartridges are useful storage centers for Voice & Performance data.

System Setup Since the use of many basic MIDI functions might depend on the contents of a specific set of Voice & Performance data, the DX7s provides a special memory location, System Setup Memory, to store basic MIDI parameters and orher data in conjunction with a Voice & Peformance Memory block.
Note On/Off This parameter works with MIDI receive only. It’s usually set to “all,” meaning that all Note On information received at the DX’s MIDI In will play a note. If the Note On/Off parameter is set to “even,” it will only play notes that have even MIDI note numbers.
MIDI System Exclusives If you use the DX7s as part of a MIDI system, there are a number of advanced MIDI functions available for your use: MIDI Device Number If the DX7s is connected to another Yamaha product, this parameter must be used to set a Yamaha System Exclusive Device Number for MIDI System Exclusive data reception or transmission.
Immediate MIDI Program Change Out This function allows you to send a program change number to an external MIDI tone generator without changing the program number on the DX7s.
Appendices -79-.
Appendix 1: Supplemental Information As mentioned at the outset, this manual has not attempted to cover all of the functions of the DX7s in exhaustive detail. To do so would have required a manual of large scale and density, one in which it would have been very difficult to locate specific information needed to begin using the DX7s.
Appendix 2: Bibliography Many of the basic functions of the DX7s are the same as those of the original DX7. Since there is a wealth of material available on the operation of the original DX7, this manual has focused on the new functions and features.
