The
Specification
Oberheim took the idea and electronics of a Minimoog synthesizer and put them in a small box, making a few changes, and in 1974 introduced the SEM (Synthesizer Expander Module), which became the building block of his polyphonic synths. By strapping two, four, or eight of these SEMs together under keyboard control, he was able to create practical, albeit large, synthesizers that could play two, four, or eight notes simultaneously. The Oberheim Polyphonic Synthesizer was born. Each SEM in an Oberheim Polyphonic generates one voice (or note).
There was an optional Polyphonic Synthesizer Programmer module (PSP-1) for the four- and eight-voice models with 16 memories, which allowed the user to store and recall some sound settings of the SEMs, and you could glide from one note or chord to another using portamento.
The Oberheim Polyphonic was later outdated by a new line of microprocessor-controlled Oberheim synthesizers, beginning with the OB-X. The OB-X was fully programmable and significantly more compact than the Oberheim Polyphonic.
Despite their maintenance cost and rarity, Oberheim Polyphonic Synthesizers are still adored by many musicians today for their characteristic sonic 'thickness' and 'depth' caused in part by the random variance between each SEM module.
