"The synthesizer "Alisa - 1387" made in Luberetskiy factory of musical instruments. This instrument has 3-octaves keyboard, a modualation wheel and the control system (regulators and buttons). The instrument consists of the following main blocks: tone generator, filter, contour filter, signal contour, modulation, sound mixer and output. Later to this synthesizer was integrated MIDI interface. Controls on the front panel: Tone generator - tuning, generator 1:3 waveforms, modulation amount, pulse width modulation, portamento, register: subfrequency, 32',16',8'; generator 2: sync on, interval, waveforms (square, sawtooth) Sound mixer - generator 1 (level), generator 2 (level), noise (level). Filter - cut off, resonance, vibration, keyboard tracking Filter contour - attack,sustain, decay, release. Modulation - tempo; waveforms ON, oscillator/filter, depth (wheel). Output - common level; output ON. Switcher to "MIDI mode". The supply voltage - 220-230V/50Hz. For 110/127V, a voltage converter is necessary. Connectors of back board: line output (Jack 1/4'') MIDI IN (5-DIN) power on power plug external triggering - generator, output, input, ON. Front board - output for head-phones (5-DIN). About "external triggering - generator, output, input, ON" - I don't know how it works and I have never used it. Perhaps it is useful thing if you have another extra analog synth."
