Overview of the RD-700
 
Basic Organization of the RD-700
 
The RD-700 can be divided into two sections: a keyboard 
controller section and a sound generator section. The two 
sections are connected internally by means of MIDI.

Keyboard Controller Section
 
This section includes the keyboard, the Pitch Bend/
Modulation Lever, the panel knobs, and any pedal connected 
to the rear panel. Actions such as pressing and releasing of 
keys on the keyboard, depressing a pedal, and so forth, are 
converted to MIDI messages and sent to the sound generator 
section, or to an external MIDI device.
 
Sound Generator Section
 
The sound generator section produces the sound. Here, MIDI 
messages received from the keyboard controller section or 
external MIDI device are converted to musical signals, which 
are then output as analog signals from the OUTPUT and 
PHONES jacks.
 
Units of Sound
 
When using the RD-700, you will notice that a variety of 
different categories come into play when working with 
sounds. What follows is a simple explanation of each sound 
category.
 
Tone
 
The individual sounds used when playing the RD-700 are 
referred to as “Tones.” The RD-700 provides 468 types of 
Tones. Tones are assigned to each part.
The Tones also include various groups of percussion 
instrument assembled into “Rhythm Sets.” Each key (note 
number) of a Rhythm Set will produce a different percussion 
instrument.
 
Part
 
A sound generator of this type which can control multiple 
sounds using one device is referred to as a multitimbral 
sound generator. The RD-700 contains a multitimbral sound 
generator capable of playing sixteen Tones simultaneously.
“Parts” are where Tones that are created when the RD-700 is 
used as a sound generator are assigned. Since different Tones 
can be assigned to each of the Parts and controlled 
individually, you can have multiple Tones play 
simultaneously (layer), divide the keyboard into separate 
ranges and have different Tones sound in the different parts 
(Split), and enjoy playing ensemble performances.
The sixteen Parts played by the RD-700’s internal sound 
generator are referred to as “Internal Parts.”
 
Local Parts and MIDI TX Parts
 
The RD-700 features three Parts (UPPER1, UPPER2, and 
LOWER) that you can use for freely controlling the Internal 
Parts with the RD-700’s buttons and keyboard. These three 
Parts that are used for controlling the Internal Parts are 
collectively known as the “Local Parts.” Three of the sixteen 
Internal Parts are assigned to the Local Parts for control (the 
RHYTHM Part is fixed at Part 10).
Furthermore, you can freely control external MIDI sound 
generators with the RD-700 in the same manner as with the 
Local Parts. You can likewise control the external MIDI 
sound generator with the three Parts (UPPER1, UPPER2, and 
LOWER), with this group of three Parts being referred to as 
the “MIDI TX (Transmit) Parts.” The external MIDI sound 
generator is assigned to these three Parts for control (the 
RHYTHM Part can also be partially set).
