The Akai MS-100 is a vintage monophonic analog synthesizer produced in the 1970s. It features a single voltage-controlled oscillator (VCO), a voltage-controlled filter (VCF), and various modulation options. The synth has a compact design with a built-in keyboard and a control panel with knobs and sliders for adjusting parameters. Other features include an envelope generator, a low-frequency oscillator (LFO), and basic built-in effects like vibrato and tremolo. The MS-100 is known for its warm and gritty analog sound. However, it is worth noting that detailed technical specifications and availability may vary since it is an older model.
