The Alisa synth, specifically the Alisa 1377 model, is a vintage Soviet analog synthesizer designed for experimental electronic music, sound effects in Soviet cinema, and scientific acoustic research.
It was manufactured in the USSR in 1986 at the Ljuberetskij Radioplant "Rodina" near Moscow.
The synthesizer features a single voltage-controlled oscillator (VCO) with four waveforms (triangle, saw, square, odd harmonics), an ADSR envelope, a filter, various modulations, vibrato, and portamento effects.
The filter can also function as an additional oscillator when the resonance knob is set to self-oscillation, producing unique and unconventional sounds.
The Alisa 1377 has a 44-key keyboard and is known for its warm, aggressive, and original analog sound.
It was primarily used within the Soviet Union and remained relatively unknown outside the country, making it a rare and sought-after instrument among collectors and enthusiasts.
