Overview of the RD-700SX
The RD-700SX 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, the sliders, 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.
When using the RD-700SX, 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-700SX are
referred to as “Tones.” The RD-700SX provides 488 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-700SX contains a multitimbral sound
generator capable of playing sixteen Tones simultaneously.
“Parts” are where Tones that are created when the RD-700SX 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, 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-700SX’s internal sound
generator are referred to as “Internal Parts.”
Zone
The RD-700SX features four Parts (UPPER1, UPPER2, LOWER1,
and LOWER2) that you can use for freely controlling the Internal
Parts with the RD-700SX’s buttons and keyboard. These four
Parts that are used for controlling the Internal Parts are
collectively known as the “INTERNAL Zone.” Four of the
sixteen Internal Parts are assigned to the INTERNAL Zone for
control (the RHYTHM Part is fixed at Part 10).
Furthermore, you can freely control external MIDI sound
generators with the RD-700SX in the same manner as with the
INTERNAL Zone. You can likewise control the external MIDI
sound generator with the four Parts (UPPER1, UPPER2,
LOWER1, and LOWER2), with this group of four Parts being
referred to as the “EXTERNAL Zone.” The external MIDI sound
generator is assigned to these three Parts for control (the
RHYTHM Part can also be partially set).
ONE TOUCH Screen
When ONE TOUCH [PIANO] or [E.PIANO] is pressed, setting
the RD-700SX to the optimal status for piano performances, this
screen is displayed.
