Overview

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.
