Overview of the VR-760
Overview of the VR-760
Basic organization of the VR-
760
The VR-760 can be divided into three sections: a keyboard
controller section, a sound generator section, and a
effects section. The three sections are connected internally
by means of MIDI.

■ Keyboard Controller Section
This section includes the keyboard, the Pitch Bend/
Modulation Lever, the aftertouch, 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.
The three sound generators that can be controlled using the
VR-760’s keyboard are described below.
Organ Sound Generator
Piano Sound Generator
Synth Sound Generator
Not only can you have these sound generators play
independently of one another, you can layer them together
or even play different sounds on different parts of the
keyboard.
The Difference Between Traditional
Organs and the VR-760’s Organ
Sound Generator
Traditional organs create sound using 91 gears called “Tone
wheels.” Each wheel has waves corresponding to the various
pitches. When rotated at a fixed speed, the Tone wheels
cause audio signals to be produced through an
electromagnetic coil, with the audio signals to be output
selected according to how the harmonic bars are set and
which keys are pressed, creating the organ’s special sound.
The VR-760’s organ sound generator replaces the traditional
organ’s whole sound-producing mechanism with digital
technology. Instead of 91 Tone wheels, audio signals are
produced constantly by means of virtual Tone wheels. The
balance of audio signals is controlled by setting the harmonic
bars and pressing the keys, which thus creates the organ
sound.
About the Piano Sound Generator
The VR-760’s “piano sound generator” is capable of
producing both acoustic and electric piano sounds. In
addition to high-quality acoustic piano sounds, the
instrument also provides a number of important vintage
electric piano sounds. When using the electric piano sounds,
the amp simulation can be set to reproduce the sounds of
“stage” models, which require an external amp and speakers,
as well as “suitcase” models, which come with their own
amp and speaker. The instrument is also equipped with a
number of effects that are often used with electric pianos.
About the Synth Sound Generator
The VR-760’s “synthesizer sound generator” is built upon the
same basic principles as Roland’s many digital synthesizer
models. This arrangement allows you to produce a variety of
different tones, and the VR-760’s tones have been rigorously
selected to enable you to get just the right sound for analog
synthesizer and other electronic sounds, string and other
acoustic instrument sounds, and other sounds suitable for
ensemble and keyboard performances.
On the VR-760, this sound generator is referred to as the
“synthesizer sound generator” or simply the “synth.” In this
Owner’s Manual, it is also referred to as the “synth part” or
“synth section.”
■ Effects Section
This is the section used for adding effects to the sounds
produced by the sound generators. Adding effects allows
you to change the sound in various ways. The VR-760 offers
effects geared toward the organ, piano, and synth sections.
On top of this, the instrument also provides reverb and
equalization that are applied to all three sound generators.
