FIELD: computer-based and electronic generation of sound images. SUBSTANCE: device has control board with melodic keyboard, tone frequency oscillator, accord structures unit, amplitude modulators of accords and melody sounds, digital mixing unit, acoustic monitor, digital-to-analog converter and amplifier. In addition device has harmonic and timbre keyboards, generator of temporal envelope of accord and melody structure overtones, generators of overtone structures and melody sounds. Device uses improved sound scale, which involves splitting octave into 171 steps. It has 171 keys for octave. Additional keyboards and generators of overtone structures and melody sounds help in production of precise approximation of rational values of main consonances (unison and octave) and achieve ranked ordering of frequencies of other consonances with respect to their adjacency or remoteness to main consonances. This results in additional musical expression possibilities with respect to fine melodic pattern and precise harmonic combination of sounds as basis for synthesis of sound images and music production. EFFECT: facilitated possibilities for musical expression and music production. 9 cl, 2 dwg
