Overview of the RD-300GX
 
The RD-300GX can be divided into two sections: a controller 
section and a sound generator section.

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 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-300GX, 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-300GX are 
referred to as “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-300GX contains a multitimbral sound 
generator capable of playing sixteen Tones simultaneously.
“Parts” are where Tones that are created when the RD-300GX 
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-300GX’s internal sound 
generator are referred to as “Internal Parts.”
 
Zone
 
The RD-300GX features three Parts (UPPER 1, UPPER 2, and 
LOWER) that you can use for freely controlling the Internal 
Parts with the RD-300GX’s buttons and keyboard. These three 
Parts that are used for controlling the Internal Parts are 
collectively known as the “Internal Zone.”
Furthermore, you can freely control external MIDI sound 
generators with the RD-300GX in the same manner as with the 
Internal Zone. You can likewise control the external MIDI 
sound generator with the three Parts (UPPER 1, UPPER 2, and 
LOWER), with this group of three Parts being referred to as the 
“External Zone.” The external MIDI sound generator is 
assigned to these three Parts for control.
