The Roland U-220 is a polyphonic analog synthesizer that was released in 1987. It was designed to be a more compact and affordable version of Roland's popular Jupiter-8 synthesizer. The U-220 features a 3-oscillator-per-voice architecture, with a single filter and a built-in 16-step sequencer. The synthesizer was widely used by musicians and producers in the 1980s, particularly in the genres of electronic, pop, and rock music.
