Within the project "Instrumentos para Todos", it was developed an electronic instrument called Matrixz. Matrixz allows all people, including those whith special needs, to compose in real-time a sequence of loop sounds, simply by puting some colored 'eggs' into a special box. Each color corresponds to a rhythmic type, and if there is a space between two 'eggs', it is considered as silence. Matrixz is a variable rhythmic matrix. The loop lenght varies in direct propotion to the amount of 'eggs' in the box. It is an extremely intuitive, simple and yet with plenty of musical possibilities.
