An analog synthesizer is an electronic musical instrument that generates sound using analog circuits and signals. Unlike digital synthesizers, which use computer algorithms, analog synthesizers create sound through voltage-controlled oscillators, filters, and amplifiers. This results in rich, warm tones that many musicians and producers prefer for their unique character. These instruments often feature knobs and sliders for real-time control, allowing users to shape sounds dynamically. Popular models include the Moog Minimoog and Roland SH-101. Analog synthesizers are widely used in various music genres, from electronic to rock, and have played a significant role in the development of modern music.
