Roland
TR-808, TB-303, Jupiter-8 — three machines that built entire genres
No single company has shaped electronic music more broadly than Roland. The TR-808 invented hip-hop's heartbeat. The TB-303 accidentally created acid house. The Jupiter-8 defined polyphonic luxury. The D-50 launched the digital era. Roland didn't just make instruments — they made entire genres possible, often in ways their own engineers never imagined.

History
Ikutaro Kakehashi founded Roland Corporation in 1972, having already built a successful career in the Japanese electronic instrument industry with Ace Tone (which produced the rhythm machines that would evolve into Roland's drum machine line). From the start, Kakehashi's vision was global — he wanted to build instruments that musicians everywhere could afford and enjoy, and he was relentless in pursuing that goal.
Roland's 1970s output was solid but not yet world-changing. The SH-series monosynths, the RS-202 string machine, and the RE-201 Space Echo (a tape-based echo and reverb unit that became a studio classic in its own right) established Roland as a reliable manufacturer of affordable, well-built instruments. But the late 1970s and early 1980s brought an extraordinary burst of creativity that would define the company's legacy.
The Jupiter-8, released in 1981, was Roland's flagship polysynth — a gorgeous eight-voice analog instrument with a warm, rich sound and a striking visual design. It competed directly with the Oberheim OB-Xa and Sequential Prophet-5, and many players considered it the equal of either. The Jupiter-4 and Jupiter-6 extended the line at different price points, and the entire Jupiter series became synonymous with premium analog polyphony.
The Juno series — the Juno-6 (1982), Juno-60 (1982), and Juno-106 (1984) — brought high-quality analog polyphony to the mass market. The Juno-106, with its simple architecture, built-in chorus, and MIDI implementation, became one of the most popular synthesizers ever made. Its warm, lush pad sounds and reliable performance made it a studio staple that remains in constant demand four decades later.
But Roland's most profound cultural impact came from two instruments that were initially considered commercial failures. The TR-808 Rhythm Composer (1980) was a drum machine that used analog synthesis rather than samples to generate its sounds. The kicks, snares, hi-hats, and cowbells sounded nothing like real drums, and the instrument was discontinued after just three years. Then Afrika Bambaataa released "Planet Rock" in 1982, using the 808's booming kick, snappy snare, and sizzling hi-hats to build a track that launched electro and profoundly influenced the development of hip-hop. The 808 became the most important drum machine in history — its sounds are now so deeply embedded in popular music that they're essentially part of the sonic vocabulary of the human race.
The TB-303 Bass Line (1981) suffered a similar fate — designed as a practice tool for guitarists who needed a bass accompaniment, it sounded nothing like a real bass and sold poorly. But when Chicago house producers discovered that cranking the 303's resonance filter produced a screaming, squelching, acid-drenched sound, an entire genre was born. Phuture's "Acid Tracks" (1987) launched acid house, and the TB-303 went from bargain-bin reject to the most culturally significant bass synthesizer ever made.
Roland continued innovating through the digital era. The D-50 (1987) introduced Linear Arithmetic synthesis, combining sampled attack transients with synthesized sustain portions to create sounds of remarkable realism and beauty. The JD-800 (1991) brought knob-per-function control back to digital synthesis. The company also produced the TR-909 drum machine (the foundation of techno and house), the SH-101 (a mono synth beloved by acid and techno producers), and the VP-330 Vocoder Plus.
Ikutaro Kakehashi was awarded a Technical Grammy in 2013 for his role in developing MIDI, the universal communication standard for electronic instruments — a standard he co-created with Dave Smith of Sequential Circuits. He passed away in 2017, but his company's instruments have shaped more genres and touched more lives than perhaps any other manufacturer in the history of electronic music.
Notable Instruments
TR-808
The TR-808 is the drum machine. Not the best-sounding, not the most realistic, not the most technically advanced — but the most important. Its analog-synthesized sounds — that deep, booming kick, that sharp snare, those sizzling hi-hats, that immortal cowbell — have appeared on more hit records than any other drum machine in history. Marvin Gaye's "Sexual Healing." Whitney Houston's "I Wanna Dance with Somebody." Kanye West's 808s & Heartbreak (the title says it all). Phil Collins' "In the Air Tonight" (that's an 808 accent pattern behind the famous drum fill). The entire genre of trap music is built on 808 kick drums tuned to musical pitches.
The 808's step sequencer — with its simple row of buttons and intuitive pattern-based workflow — defined how electronic musicians think about rhythm programming. Its accent, shuffle, and swing controls gave beats a human, dynamic quality that rigid quantization couldn't match. Afrika Bambaataa and the Soulsonic Force's "Planet Rock" was the 808's big bang moment, but the instrument's influence extends into virtually every genre of popular music made since 1982.
TB-303
The TB-303 is the most unlikely success story in music technology. A commercial failure designed for a purpose it was terrible at (emulating bass guitar), abandoned by Roland after poor sales, picked up for pennies at pawn shops by producers in Chicago — and then it changed the world. When DJ Pierre of Phuture started twisting the 303's cutoff and resonance knobs while its built-in sequencer ran, the squelching, screaming, acid sound that emerged became the basis of an entire musical movement.
Acid house wasn't just a genre — it was a cultural revolution that transformed nightlife, fashion, and youth culture across Europe and beyond. And it was all built on the sound of a failed bass machine. The 303's single oscillator, its distinctive diode ladder filter, its slide and accent controls, and its gloriously imprecise step sequencer combined to produce a sound so unique and so compelling that it remains as vital today as it was in 1987. Every modern synth with an "acid" preset is paying tribute to the TB-303.
Jupiter-8
The Jupiter-8 is Roland's most prestigious analog synthesizer — a beautifully designed eight-voice polysynth with two oscillators per voice, a flexible filter section, and a sound that is simultaneously warm and crystalline. Its voice architecture sits in a sweet spot between the thick, aggressive character of an Oberheim and the precise, controlled sound of a Prophet-5, giving it a versatility that made it equally at home in pop, new wave, synth-pop, and film scoring.
Duran Duran's Nick Rhodes made the Jupiter-8 central to the band's sound — those shimmering, elegant synth textures on Rio and Seven and the Ragged Tiger are pure Jupiter. Howard Jones, Depeche Mode (on their earliest material), and Japan's Richard Barbieri all relied on it. The Jupiter-8's split and layer modes, its arpeggiator, and its intuitive panel layout made it a performance instrument of real depth. Today it's one of the most valuable vintage synthesizers, commanding prices north of $30,000 for clean examples — a testament to both its sonic excellence and its iconic status.
Juno-106
If the Jupiter-8 is the champagne, the Juno-106 is the finest craft beer ever brewed — accessible, satisfying, and something you'll reach for every single time. The 106's single-oscillator-per-voice architecture is deceptively simple. One DCO, one filter, one VCA, and the famous Roland chorus circuit. That's it. And yet from those modest ingredients, the Juno-106 produces some of the most gorgeous pad sounds, warm basses, and shimmering textures in all of synthesis.
The built-in chorus is the secret sauce — it transforms the Juno's slightly thin raw sound into a wide, lush, animated stereo image that sounds far more expensive than the instrument's modest price tag ever suggested. The Juno-106 became a staple of house, techno, synth-pop, and ambient music. Its sounds are so ubiquitous that you've heard them thousands of times without knowing it. Enya, The Cure, Tame Impala, and virtually every electronic music producer born after 1980 has used or sampled a Juno-106. It is quite possibly the most-recorded synthesizer in history.
