SH-101

The Roland SH-101 is a monophonic analog synthesizer introduced in 1982. Its voice consists of a single voltage-controlled oscillator offering sawtooth and pulse waveforms with pulse-width modulation, alongside a sub-oscillator and a noise generator, routed through a resonant low-pass filter with an envelope generator and an LFO for modulation. It also includes a built-in step sequencer and arpeggiator, CV/gate sockets for connecting other analog equipment, and can be powered by internal batteries.
