Rgb_1 algorithms

 

Rgb_1 was first main package of the interactive schemes produced for the Rgb installation. Its main focus is harmonical and tonal aspect of the musical communication..

 

Polyphonic field concept

 

"Polyphonic field" concept was the main algorithm of Rgb1.

 

In this concept audience activity is cruicial for the musical composition. One could say that while audience creates musical content, performers create form of the composition.

 

 

There is field of 88 sensors on the projection screen.

 

Every sensor represents one tone of the sensor field. Tones are layered by pitch from the most lower in the lower part of the canvas to the most higher tones in the upper part of canvas. Together they create certain harmonical system. Connection between sensor and light turns the tone on and off.

 

Every colour of the RGB light represents one sound (instrument) with distinguishing characteristic (for example blue colour represent pads with long attack, red colour sound with percusive characteristic).

 

Combination of two different colours causes new colour creation (yellow, violet or azur). This is the second layer of the system which turns on more complex sounds in the forms of samples and other more complex sound material.

 

 

System has its own visualisation, first layer of the system is represented by dots, second by squares.

 

Performers have many tools how to form the music into composition: masking the sensor net (only certain parts are active), recording played sequences into loops and playing them back in the system as new tracks of the compositions, turning on and off certain circuits of the system (which colour, which layer of the system is active), changing banks, harmonical system in real time.

 

In a way musician play on the whole net of sensors like on some complex harmonical instrument.

 

Result is polyphonic music, which is characteristic and in a way distinguishing by its pointilistic, on one hand minimalistic but on the other non repeating sequencially endless character.
