The Roland arranger keyboard features several technologies, which are explained below:

V-Link

Audio and Video Together At Last! Using V-LINK, musicians can play video from their electronic instrument--or even control a live video camera--when used with Edirol video products. All it takes is a simple V-LINK connection to make the magic happen. With V-LINK, musicians have a powerful new interface for realtime audio and video integration. Welcome to the future of music. With V-LINK, musicians can take their performance to the next level by seamlessly integrating audio and video. Imagine hitting a key and instantly triggering a corresponding video clip. Or tweaking a filter knob to create radical visual effects. Or seamlessly blending different video clips at the touch of an audio fader. These are just some of the possibilities available with V-LINK. Integrating video with a musical performance used to be a complicated process. In fact, it was more of an afterthought than an extension of the music. Roland's V-LINK has changed all that forever, giving musicians the power to control video while performing on stage. Using Edirol's V-1 4-channel Video Mixer, for example, musicians can create exciting visual effects that sync to BPM, or even control the picture from a live video camera.

SRX

SRX sounds are industry-leading sound for “SRXpandable” Synths. The SRX-Series is a sound library developed with a strong focus on quality. Each 64MB board contains waveforms that have been meticulously sampled in world-class studios—using only the finest tools—for a level of realism and expressiveness like you’ve never experienced. For whatever sounds you need, look to the SRX-Series when quality matters most.

GS

The GS Format is a Roland specification which defines the manner in which multitimbral sound sources respond to MIDI messages. The GS Format includes specifications of sounds, functions available for Tone editing, effects (chorus and reverb), and additional standardized parameters. Any sound source that carries the GS Format logo is compatible with any GS Music Data (music data created under the GS Format).

GM2

General MIDI is an industry-wide set of specifications for sound sources that allow music data to be created regardless of manufacturer or specific models. General MIDI defines the minimum number of voices that should be supported, the MIDI messages that should be recognized, which sounds correspond to which Program Change numbers, and the layout of rhythm sounds on the keyboard. The General MIDI logo on a sound source indicates compatibility with song data which also carries the General MIDI logo. M2 (General MIDI System Level 2) is a set of standards for editing voices not covered by GM1. GM2 also defines the operation specifications of effects and other elements in detail, and enables more sophisticated performance expression and greater compatibility, by expanding range of voices.

DigiScore

This function displays the notations of Music Files; all preset songs, of songs you record yourself, or of Standard MIDI Files- right on the large LCD Screen. Notation pages are turned automatically and the size of the staff/note display can be adjustable as desired.

D-Beam

The beam is a hand controlled sensor which allows you to control various aspects of your performance. The D BEAM Controller uses an infrared beam of light to send various controller changes depending on the function selected. (D BEAM light has been colored for illustrative purpose only. Actual infrared beam is invisible).

COSM

Composite Object Sound Modeling. Once a musical instrument generates sound vibrations, it reaches the human ear through various mediating, objects, each of which significantly affects the sound. The material and configuration of the instrument, the electric/magnetic amplifying system, the air and the reverberation of the room all affect the final sound. Sound modeling, the latest DSP technology, "virtually" reconstructs these objects. Roland's breakthrough Composite Object Sound Modeling (COSM) uses the advantages of multiple modeling methods and succeeds in accurately emulating existing sounds, as well as producing sounds that have never before been created.
