The Roland SH-101 is an analog synthesizer manufactured by the Roland Corporation between 1982 and 1986. Though it was a commercial failure, it became a staple of electronic music in the 1990s, particularly house music.
The SH-101 is monophonic, meaning it can only play one note at a time. It has a single oscillator and a sub-oscillator, a low-pass filter, a mixer allowing users to blend different waveforms plus a noise generator, and an arpeggiator and sequencer. An ADSR envelope generator controls the filter and VCA, and the filter, VCA, pitch and pulse width can be controlled with an LFO. The SH-101 also features an arpeggiator and sequencer. Users can attach an optional handgrip with modulation controls and shoulder strap to play the SH-101 as a keytar, and it could also be powered via battery. According to MusicRadar, the SH-101 has "snappy and razor-sharp" bass, "squelchy and expressive" leads, and a "piercing yet smooth" filter.
