Electromusical keyboard instrument '' Electronics EM-141 '' (Venta).

Electronic musical instrumentsProfessionalElectromusical keyboard instrument "Electronics EM-141" (Venta) was produced in the late 80s of the 20th century. It is a one-channel, five-octave, polyphonic, portable instrument. Designed for performing pop and classical pieces as a solo or accompanying instrument in professional and amateur ensembles, as well as at home. The instrument consists of the following sections: flute section, percussion section, synthesizer section, chorus-flanger section. The flute and percussion sections of the instrument represent the generally accepted structure of the organ. The sound timbre is synthesized from 10 harmonics by a set of their levels. Timbre formation, built on a pure sinusoidal signal, allows you to simulate the sound of a Hamond organ, vibraphone and other instruments. The synthesizer section, which contains a controlled filter device in a controlled envelope, simulates wind instruments (French horn, English horn, and others), as well as a wide variety of sounds typical of synthesizers. The chorus-flange section enriches the instrument, gives the instrument sounding properties of spaciousness and simulates the effect of the sound source rotating in space. The KEMI case is a part of the protective casing of the device. The instrument provides: high stability of the frequency of the leading oscillator, due to the use of quartz automatic frequency control, the minimum error of the intervals of the scale relative to the equal-tempered musical scale, the ability to shift the entire tuning of the instrument by +/- 1/4 tone, rich timbre coloring with the ability to adjust the decay of the sound ... Technical characteristics: The number of manual registers: flute with a set of timbre 10 (16; 5 1/3; 8; 4; 2 2/3; 2; 1 3/5; 1 1/3; 1; 1 1/2), flute fixed switching on 1, percussion with a set of level 7 (4; 2 2/3; 2; 1 3/5; 1 1/3; 1; 1 1 / 2_), bass registers of fixed switching in the volume of 2 lower octaves 2. Full sound range of 8 octaves. The error of the intervals of the scale relative to the uniformly tempered scale, no more than 0.05%.
