Roland SH-101 is a synthesizer from the early 1980s, manufactured by Roland. It is a small, 32 key, monophonic analog synthesizer. It features one oscillator with 3 simultaneous waveforms, an 'octave-divided' square sub-oscillator, triangle and square/pwm waveform. It has a low-pass filter/VCF capable of self oscillation. The self oscillation filter can be used to make bass drum sounds.

The controls are simple to use as there is a slider or switch available for every single parameter, and there is an external trigger input to control the speed of the sequencer or the arpeggiator
