January 1980, San Rafael (California): a 25-year-old engineer named Roger Linn ships the Linn LM-1 Drum Computer - the world's first drum machine that plays back digital samples of real drums instead of analogue imitations. Price: US$4,995 (roughly US$18,800 in 2024 money). Until then, drum machines went “pew-pew-pew”: the CR-78, the Rhythm Ace, the Boss DR-55 all ran analogue oscillators that at best resembled real drums from a distance. The LM-1 sounded like a live drummer - because inside it were 12 real samples, recorded from actual kits. Over the four years of its production life the machine showed up on records by Prince, Stevie Wonder, Peter Gabriel, The Human League - and redefined what 80s pop sounded like.
How Roger Linn invented the digital drum machine
Roger Linn (born 1955, Los Angeles) worked as a session guitarist until 1979, playing on Leo Sayer and Barbra Streisand dates. In 1978, commissioned by Leon Russell, he built a prototype electronic sequencer that could synchronise multiple tape machines. While working on it Linn heard a drum recording that had been digitally looped and realised: if you record individual drum hits to memory and trigger them from a keyboard, you get a perfect drum machine.
He built the first prototype on his kitchen table in Los Angeles over the winter of 1979. 2 KB EPROM chips, an Intel 8048 processor, a keyboard with 12 rubber pads (one per drum), a monochrome LCD. In January 1980 Linn incorporated Linn Electronics Inc. in San Rafael, Marin County, hired five employees and started a production run.
An early detail: the first LM-1s were built on a garage assembly line, and Roger Linn soldered the boards on the first fifty machines personally. Each unit was burn-in tested for eight hours with all 12 voices playing at once.
Series I specs (1980)

- Price: US$4,995 in the States, £3,800 in the UK, 25,000 DM in Germany
Across the first year Linn Electronics built and sold 525 units. The customer list reads like a roll call of early-80s pop: Prince, Stevie Wonder, Peter Gabriel, John Foxx, Fleetwood Mac, Pink Floyd, Hal Blaine, David Bowie. The LM-1 became a status object - its presence in a studio meant you were working with a pro, not “a guy with a Roland CR-78 budget”.
Prince and his ten LM-1s
Prince Rogers Nelson bought his first LM-1 in May 1981 at Knut Koupée Music in Minneapolis. Two years later he owned ten LM-1s - one at Paisley Park, one at his home studio, two spares, two in touring cases, and a few more for experiments. He was the only known musician of the era to own that many.
Prince albums where the LM-1 dominates:
- Controversy (1981) - first appearance
- 1999 (1982) - all drums on the record
- Purple Rain (1984) - “When Doves Cry”, “Computer Blue”, “I Would Die 4 U”
- Sign o' the Times (1987) - the title track entirely on LM-1
Prince often swapped a pad on the LM-1 for a “noisy” preset - he would crack the lid, physically swap the sample chip, or reprogram it. The signature “broken” kick on “When Doves Cry” is his modification of the factory preset.
“I bought the LM-1 so I wouldn't have to hire a drummer. A drummer gets tired, makes mistakes, wants lunch. The machine plays flawlessly for fourteen hours straight, and I hear exactly what's in my head. That saves me two thousand dollars a week”, - Prince in Musician Magazine, 1982.
LinnDrum LM-2 (1982) - going mass-market
The LM-1's success made Linn Electronics a commercial entity, but the technology was already moving on. In 1982 Roger Linn released the LinnDrum LM-2 - an improved version at US$2,995 (against the LM-1's US$4,995). New samples (snare with reverb, open/closed hats), expanded memory, a cleaner interface.
The LM-2 was far more widely sold: about 5,000 units across 1982-1985. That machine sits on most of the pop hits of the period: “Take On Me” by a-ha (1985), “Tainted Love” by Soft Cell (1981), “Dolce Vita” by Ryan Paris (1983), “Beat It” by Michael Jackson (1982), “Rebel Yell” by Billy Idol (1983).
Unlike competing machines (Simmons SDS5, Oberheim DMX, Roland TR-808), LinnDrum sounded realistic: a casual listener often couldn't tell it wasn't a live drummer. That was what made it universal.
The 1986 bankruptcy
By 1985 the drum machine market was crowded with Japanese competitors: Yamaha RX11, Roland TR-707, E-mu SP-12 (1986). All cheaper than the LinnDrum, all audibly better than Simmons. Linn Electronics couldn't compete on price. In October 1986 the company filed for bankruptcy with US$1.3 million in debt.
The assets and patents were bought by Forat Electronics, which ran out the remaining LM-2 production under licence. Roger Linn himself moved on to Akai, where he designed the legendary Akai MPC60 (1988) - the sampler/sequencer that shaped the sound of 90s hip-hop. That's a separate story.
Collector value and a 2020 revival
On Reverb.com and eBay in 2024 a working Linn LM-1 goes for US$12,000-20,000 (LinnDrum LM-2: US$3,000-5,000). More than a Fairlight Series II, comparable to a Moog Modular. The reason - scarcity: estimates put working LM-1s remaining in the world at around 200-300.
In 2020 Roger Linn (now 65) launched LM-1 Revived through his company Roger Linn Design - an exact hardware reissue with the original samples, the same processor, the same interface, in a modern chassis. Price: US$2,495. The first year's 300 units sold out.
What the LM-1 did for 80s sound
- Replaced the live drummer with a program - recording budgets dropped fivefold
- Made perfectly repeatable rhythm possible - a club standard that hadn't existed before
- Set the aesthetic of “clean” drum sound: no room resonance, only the sample
- Taught musicians to think of rhythm as a pattern rather than a performance
- Opened the door for samplers (Fairlight, E-mu SP-12, Akai S1000) in the 80s
Neighbouring gear pieces - Roland TR-909, Fairlight CMI. The TR-909 carried the analogue aesthetic, Fairlight the universal sampler, the LM-1 its narrow niche: a convincing imitation of live drums. Each of the three spawned a branch of electronic music - and all three are still in working studios in 2024. Tracks where you can hear LinnDrum clearly - “Dolce Vita” Ryan Paris, “Take On Me” a-ha, “Tainted Love” Soft Cell.
