Overview of the RD-300SX
The RD-300SX 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.
Tone
The individual sounds used when playing the RD-300SX are referred
to as “Tones.”
The RD-300SX has 340 individual tones, and a variety of tones can be
used in performances.
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-300SX contains a multitimbral sound generator capable of
playing sixteen Tones simultaneously.
“Parts” are where Tones that are created when the RD-300SX is used
as a sound generator are assigned. Different Tones can be assigned
to each of the Parts and controlled individually.
* As these are performances with 16 parts, they require control from
external devices via MIDI or USB.
Zone
With the RD-300SX, you can freely control two of the above-
mentioned parts using the RD-300SX’s buttons and keys; these two
parts are referred to as the UPPER zone and LOWER zone. You can
layer each zone (Dual Play; p. 21) or play them in different ranges of
the keyboard (Split Play; p. 22).
When changing settings values, you can use [DEC] and [INC].
[DEC], [INC]
Pressing [INC] increases the value, and [DEC] decreases it. Keep the
button pressed for continuous adjustment. For faster value increases,
keep [INC] pressed down and press [DEC]. For decreasing value
faster, keep [DEC] pressed down and press [INC].
