Synthesizer

• 1. Early Electronic Precursors

  ›

  In 1938, the Hammond Organ Company unveiled the Novachord. This massive instrument relied on 72 voltage-controlled amplifiers and 146 vacuum tubes to generate sound. It stood as a precursor to modern synthesis but remained too large for most venues. Earlier still, the Telharmonium used rotating generators to produce tones over telephone lines in the late 19th century. By 1957, Harry Olson and Herbert Belar finished the RCA Mark II Sound Synthesizer at Princeton University laboratories. The machine required punched paper tape to control its operation and contained 750 vacuum tubes inside. Milton Babbitt, a composer at Princeton University, used this system almost exclusively for his compositions. Columbia-Princeton Electronic Music Center acquired the unit and kept it within their facility. Hugh Le Caine completed the electronic sackbut in 1948 with keyboard sensitivity allowing vibrato and glissando.

• 2. The Modular Revolution

  ›

  Robert Moog introduced the first commercially viable synthesizer in 1964. His design featured modular components connected by patch cables to route signals between oscillators and filters. Don Buchla created the Buchla Modular Electronic Music System around the same period using touchplates instead of keyboards. Touchplates transmitted control voltages based on finger position and force applied by the player. Moog's inclusion of a standard keyboard made his instrument more accessible to musicians than Buchla's alternative. Both engineers initially avoided calling their creations synthesizers due to negative associations with earlier RCA models. By the 1970s, the term became standard across the industry. The voltage-controlled oscillator allowed pitch to be controlled through electrical voltage rather than mechanical linkages. Envelopes, noise generators, and sequencers became standard components within these systems. These innovations transformed laboratory curiosities into tools usable by working composers and performers.

• 3. Portability And Polyphony

  ›

  Moog launched the Minimoog in 1970 as a smaller, cheaper version of his original modular system. It was the first synthesizer sold directly in music stores for live performance use. Franklin Crawford noted Robert Moog's death from brain cancer decades later while reflecting on this legacy. The Minimoog standardized the concept of self-contained instruments with built-in keyboards. Early synthesizers could only play one note at a time, limiting them to basslines or solos. Tom Oberheim created some of the earliest commercial polyphonic synthesizers like the OB-X in 1979. Sequential Circuits released the Prophet-5 in 1978, which used microprocessors to store sounds in patch memory. Users no longer needed to adjust cables and knobs every time they wanted to recreate a sound. This shift facilitated a move from unpredictable sounds to producing familiar packages of audio. ARP products like the Odyssey rivaled the Minimoog in the American market. EMS synthesizers found homes with European art rock acts including Brian Eno and Pink Floyd.

• 4. Digital Technology And Sampling

  ›

  The Yamaha DX7 launched in 1983 as the first commercially successful digital synthesizer. It sold more than 100,000 units and remains one of the bestselling instruments in history. John Chowning developed frequency modulation synthesis at Stanford University before Yamaha licensed the technology. Critics described its sounds as harsh, glassy, and chilly compared to warm analog tones. MIDI arrived in 1982 as a standardized means of synchronizing electronic instruments across different brands. The Fairlight CMI appeared in 1979 with the ability to record and play back samples at different pitches. High prices made it inaccessible to amateurs until competitors lowered costs. Kate Bush and Peter Gabriel adopted the Fairlight for high-profile pop music productions. Early samplers included the E-mu Emulator released in 1981 and the Akai S-series arriving in 1985. Roland introduced the D-50 in 1987 blending linear arithmetic algorithms with samples. Korg released the M1 in 1988 featuring sampled transients and loops. More than 250,000 units of the M1 were sold, making it the best-selling synthesizer ever.

• 5. Software And Analog Revival

  ›

  Propellerhead Software released ReBirth in 1997 as one of the first software synthesizers playable via MIDI. Reality by Seer Systems followed shortly after allowing real-time performance through digital interfaces. Cubase updated in 1999 enabled users to run software instruments as plug-ins within their sequencers. Reason launched in 2000 introducing an array of recognizable virtual studio equipment. Older analog synthesizers regained popularity in the 2000s sometimes selling for much more than original prices. New affordable analog synthesizers appeared in the 2010s from companies including Moog, Korg, Arturia, and Dave Smith Instruments. Modern surface-mount technology made analog synthesizers cheaper and faster to manufacture. The market for patchable modular systems rebounded in the late 1990s after years of decline. Mackie lost a lawsuit against Behringer in 1997 because copyright law did not cover circuit board designs. Clones became legal where patents had expired allowing companies like Behringer to model famous instruments.

• 6. Cultural Impact And Genre Evolution

  ›

  Switched-On Bach released in 1968 took synthesizers to the mainstream through Wendy Carlos arrangements of Bach compositions. Debates about appropriateness arose regarding baroque music but serious classical circles quickly abandoned the instrument. Keith Emerson became the first major rock musician to perform with the Moog synthesizer in 1970. His performances helped take Emerson Lake & Palmer to global stardom using the instrument as a trademark. String synthesizers were used by progressive rock bands including Camel, Caravan, Electric Light Orchestra, Gentle Giant, and Renaissance. Stevie Wonder placed the Minimoog at the center of his work within African-American music. Disco artists including Abba and Giorgio Moroder widely used the Minimoog during the late 1970s. Gary Numan's 1979 hits Are Friends Electric and Cars made heavy use of synthesizers for pop success. OMD released Enola Gay in 1980 using distinctive electronic percussion and synthesized melody. Soft Cell utilized a synthesized melody on their 1981 hit Tainted Love. The Yamaha DX7 E PIANO 1 preset became particularly famous especially for power ballads performed by Whitney Houston and Prince.

• 7. Industry Labor And Union Conflicts

  ›

  The rise of the synthesizer led to major changes in the music industry including job displacement comparable to sound film arrival in the 1920s. One keyboardist or music programmer could produce the same range of sounds as an entire orchestra threatening session musicians. For a period the Moog was banned from use in union work negotiated by the American Federation of Musicians. Robert Moog felt that the AFM had not realized his instrument had to be studied like any other. He imagined critics believed all sounds existed inside the machine waiting to be triggered by buttons. Walter Sear persuaded the AFM that the synthesizer demanded skill leading to acceptance of the category synthesizer player. Players faced suspicion and hostility for years after gaining entry into the union. In 1982 following a tour by Barry Manilow using synthesizers instead of an orchestra, the British Musicians Union attempted to ban them. A few skilled programmers found employment creating sounds for other acts during the 1980s. The conflict highlighted tensions between technological progress and traditional notions of musical authenticity.
