Electric musical instrument '' Tom-1501 ''.
Electronic musical instrumentsProfessionalThe electronic musical instrument "Tom-1501" was produced in the early 80s of the 20th century by the Tula association for the production of musical instruments "Melodia". "Tom-1501" is an electronic musical instrument with an orchestral effect of a portable type, assembled on semiconductor devices, intended for solo performance of musical works of any genre and accompaniment as part of an ensemble. It is a one-channel keyboard instrument that imitates the sound of a piano, harpsichord, orchestra's bow group consisting of violins, violas, double bass; brass instruments. The instrument consists of the following units: a master oscillator, twelve manipulators, an infra-low frequency generator, a delay line, a breaststroke filter, a filter block, output amplifiers, a power supply, a volume pedal, and a sustain pedal. The formation of all tones is carried out from one master oscillator, which excludes the possibility of detuning the instrument during its operation. The basis of the instrument's timbre formation is the synthesis of 6 registers of the left and 5 registers of the right parts of the keyboard. Tom-1501 allows you to quickly change the character of the sound during performance, using effects: sustain, vibrato, chorus. Technical characteristics: Full volume of the keyboard, octave 5 1/12.
