The synth Roland built when nobody at Roland believed analogue had a future.
The Roland SH-101 was released in late 1982 into a market that was, by most reasonable measures, already done with analogue synthesis. The Sequential Prophet-5 had been the studio polysynth of choice for four years; Yamaha's DX7, the digital FM synthesiser that would relegate analogue to a curiosity within eighteen months, was already in development and would ship in May 1983. The expensive end of the market was moving toward digital. The middle of the market was moving toward polyphonic. The cheap end of the market was, more or less, moving toward not buying a synthesiser at all.
Roland's answer, in this context, was to release a single-VCO, single-VCF, single-envelope, monophonic synthesiser, running on six AA batteries, with a thirty-two-step sequencer and a guitar strap mount, at a list price of US $495. The decision looked, at the time, like Roland accepting that they could not compete with the polysynths and aiming for the bottom of the market with a back-to-basics product that would sell on price and durability. The decision turned out to be correct, but for none of the reasons Roland had in mind. The SH-101 sold about fifty thousand units before being discontinued in 1986. Most of those units went to working musicians who used them as bass synths, lead synths and second-keyboard parts. A smaller and louder portion went to bedroom producers and to electronic-body-music bands who had never had access to anything as expressive at this price point before.
The instrument itself is, on inspection, almost laughably reduced. One oscillator, with sub-oscillator, four waveforms (sawtooth, pulse, variable-pulse, sub-octave). One filter, twenty-four-decibel-per-octave low-pass, with resonance. One ADSR envelope generator. One LFO with three waveforms. A small noise source. A simple mixer between the four sources. A modulation matrix that lives entirely in switch positions on the front panel: each routing decision is a flip of a three-position lever. There are no menus, no presets, no patch memory of any kind. The user is the patch memory; everything they want to remember is something they have to write down on paper.
I never really liked the SH-101. I kept it anyway. Richard D. James, in conversation, c. 2001 · paraphrased from numerous interviews
The instrument's relationship to the genre this archive covers begins around the time the EBM scene was crystallising around the first wave of 4/4 European industrial. Front 242 had it; DAF had Korg MS-20s but used SH-101s for sequenced bass; Skinny Puppy had a pair (one for live, one for studio); Daniel B. of Front 242 used the SH-101 onboard sequencer extensively; Liaisons Dangereuses ran one through a Boss CE-2 chorus and a tape echo and discovered, in the process, the cleanest version of the EBM bass sound the early decade produced. By 1986, the SH-101 was on records by every label in the genre's middle market: Wax Trax in Chicago, Mute in London, Antler in Brussels, Side Effekts in Cleveland. It was not, anywhere, the prestige synth: the prestige synth was the Prophet-5 or the OB-Xa. The SH-101 was the synth the second keyboard player owned or the synth the bass player picked up in tour breaks or the synth that was on the floor of the rehearsal room because no one bothered to put it back in the case.
Two technical points worth registering here, because they recur in later equipment files. First: the SH-101's resonance circuit, when pushed past about three-quarters of full, self-oscillates into a pure sine tone. This is the technical mechanism behind the acid sound: a square-wave oscillator routed through a resonant filter modulated by an envelope generator, with the resonance set high enough that the filter contributes its own pitched tone to the output. The TB-303, released the same year as the SH-101 and discontinued in 1984, became famous as the acid-house instrument, but the technique is older than either: the SH-101 produces a defensible acid bass with the right settings. Second: the onboard sequencer is rudimentary by any standard (thirty-two steps, no memory beyond the current pattern), but it has a feature later step-sequencers borrowed extensively, which is that the gate-time of each note is a function of how long the user holds the key during programming. You can write rhythm into the sequence as well as pitch.
The Bureau files the SH-101 first under Equipment because of what it represents structurally. Industrial music, in the period this archive covers, has been made by people with limited budgets, in domestic spaces, working with equipment that was not designed for studio use and that frequently was not designed for music at all. The SH-101 is the genre's ideal instrument: cheap when new, solid enough to survive being thrown into a van, expressive enough to carry a record and limited enough that working within its constraints produces a recognisable family of sounds. That almost every industrial-EBM record made between 1983 and 1990 has at least one SH-101 part on it is not, in the Bureau's reading, a coincidence; it is the sound of the genre being made by the people who could afford to be making it.
The instrument was discontinued in 1986. The decision was, in retrospect, premature: SH-101 prices on the second-hand market began rising almost immediately and have not stopped. As of 2026, a working SH-101 in original condition sells for between US $1,800 and US $3,500, depending on colour (the red ones are most coveted, then the blue ones, then the standard grey), originality of components and whether the strap mount is intact. The Bureau owns one, modestly. It has not been used on any of the work this archive references. It exists in a flight case, in a flat in a city this archive will not name and is taken out about twice a year for what the Bureau characterises as structural maintenance.
