Overview of the RD-300SX

Basic Organization 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

(controllers such as keyboard, pitch bend lever, etc.)

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

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).

Basic Operation of the RD- 300SX

Changing the Settings Values

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].
