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. The LFO is very fast and can be used to make fast arpeggios with decay down to zero volume, without retriggering the ADSR. Another unique feature is being able to select noise as a modulation source for both pitch and the filter, resulting in distortion-like effects. External control is achieved using CV/Gate and not MIDI. The SH-101 was produced in three colors: gray, blue, and red. Contrary to legend, the SH-101 never came in white. A shoulder strap can be connected to it, and a small handgrip can be plugged into the side which contains a pitch bend wheel and a pitch modulation trigger. When slung over the shoulder it doubles as a "keytar".
The Roland MC-202 MicroComposer, a monophonic analog synthesizer/sequencer released by Roland in 1983, is similar to both the Roland TB-303 and Roland SH-101 synthesizers, featuring one voltage-controlled oscillator with simultaneous saw and square/pulse-width waveforms and a resonant -24db filter.
The popularity of the SH-101 is such that many companies have seen fit to cater to a significant market of musicians who want the sound of the 101 but are not able to pay for one. This has led to a rise in clones—devices designed to emulate the SH-101 for a much cheaper price. Such devices are the "Lush-101" by D16 group, "TAL-BassLine-101" by Togu Audio Line, and "PowerCore 01" for the PowerCore platform.
In 2014, Roland released the AIRA System-1 synthesizer which includes a digital emulation of the SH-101 that could be operated both as software on a computer and directly from the hardware keyboard.
