History and Products[edit]

SEM (1974–1979, 2009–)

Oberheim Electronics[edit] Originally a manufacturer of electronic effects devices (most notably the Maestro phase shifter),[3] and briefly an ARP Instruments dealer,[3] Oberheim went on to create several ground-breaking products in the early days of synthesizers and electronic music including the DS-2 (one of the first digital music sequencers) and the Synthesizer Expansion Module (SEM).

Oberheim 4 Voice (1975–1979)

Oberheim's Two-voice TVS-1, Four-voice FVS-1 in 1975,[1] and Eight-voice in 1977,[4] (which was the four voice frame with an external 4 SEM module) were among the first commercially available polyphonic synthesizers. Configurations were based on the SEM. The Two-voice synthesizer included a two channel voltage controlled sequencer, and the Four-voice and Eight-voice machines included a rudimentary Programmer, capable of recalling sound settings. Oberheim's later synths like the OB-X and OB-Xa abandoned the relatively bulky SEMs in favor of individual or compact voice cards, and common cabinetry and power supplies. Oberheim continued to make synthesizers until the late 1980s. Other notable Oberheim synthesizers include the OB-1 (monophonic), the OB-8, the Xpander, the Matrix-6, the Matrix-12, and the Matrix-1000 marketed after the acquisition by Gibson.[5][6]

Xpander (1984)

Oberheim drum machines[edit] Oberheim's DMX drum machine, a staple of early hip-hop music,[7] lent its name to the Producer Davy DMX, electro musician DMX Krew, and is still used in dancehall reggae music.

Both Marcus Ryle and Michel Doidic worked for Oberheim as instrument designers before helping develop the ADAT
multitrack digital tape recorder for Alesis, (a 'prosumer' grade digital recording multitrack deck designed to compete with the Tascam DA series of digital multitracks) and then moving on to found Line 6 together.[8] Oberheim/Gibson[edit]

OB-Mx (1994)

Oberheim went bankrupt and was acquired in 1985 by a group of lawyers who changed the name to Oberheim ECC. Tom was creatively still at the helm, although he left the company within a couple of years to start a new venture called Marion Systems. After a second bankruptcy in early 1988, Gibson Guitar Corporation, a larger musical instrument manufacturer (who, incidentally, also owned the Maestro brand), acquired Oberheim, and in collaboration with Don Buchla

produced the OB-Mx,[10] the Echoplex Digital Pro in collaboration with Aurisis Research, and the Strummer with Viscount International. Ironically, Gibson had split from its parent company, Norlin, in 1986. Norlin handled distribution for Oberheim's major competitor, Moog Music. Oberheim/Viscount[edit]

OB*12 (2000)

The trademark was later licensed to Viscount International, an Italian digital-organ producer. Viscount developed in a few years various instruments that were very innovative for the time and are still in demand: the digital synth Oberheim OB*12,[11] the guitar DSP GM-1000 with lots of effects,[12] the MC series of master keyboards,[13] and the OB32, a portable and inexpensive imitation of the popular Hammond series of organs.[14][edit] In 2009, Tom Oberheim

announced that he was manufacturing a new version of his classic analog SEM.[15][16][17][18] In 2011–2012, Tom Oberheim

announced a four-voice SEM called "Son Of 4 Voice" (SO4V),[19] as well as an updated version of the classic Two-Voice known as the Two-Voice Pro.[20] The "Son Of 4 Voice", also known as SO4V, the Two Voice Pro started shipping in 2014.[21]
