Overview of the RD-300GX
The RD-300GX can be divided into two sections: a controller
section and a sound generator section.
fig.00-G01e
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.
