ELECTRONIC MUSICAL KEYBOARD INSTRUMENT "MAXBOX" Russian patent published in 2014 - IPC G10C3/12 C10H7/00 

FIELD: physics.

SUBSTANCE: electronic musical keyboard instrument includes a system of interconnected sound-extraction units, wherein each unit is designed to generate one fundamental audio frequency and is matched on that frequency with audio frequencies generated by other units, wherein the number of sound-extraction units, the principle of their matching on generated audio frequencies, the labelling of sound-extraction units on the instrument and spatial arrangement thereof are defined by a multi-step musical pitch, formed from a discrete set of monochromatic sounds, the instrument being characterised by that the system of sound-extraction units consists of independent keyboards with control units and is configured to use an octave with the step 2, 3, 4, 5, 6, 7, 8, 9, 10, wherein the number of tones in an octave varies from 4 to 25, the structure of the octave itself has the capacity for a combinational set of a series of non-uniform tones: tone, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8, 1/9 and 1/10 tone, wherein the keyboard are arranged in two levels.

EFFECT: disclosed musical instrument has broader capabilities owing to a system of sound-extraction units, based on use of a new type of musical pitch.
