Trident History — Korg

Trident

1980–1982

The Korg Trident is a polyphonic multi-section synthesizer released by Korg in 1980, combining three distinct synthesizers within a single instrument: a polyphonic section with two VCOs, alongside dedicated String and Brass sections. The polyphonic synthesizer section allows for eight-note polyphony with dual oscillators. The String section offers an ensemble effect and simple attack/release envelope controls, whereas the Brass section features an independent filter and a dedicated ADSR envelope. These sections can be assigned to two different regions of the keyboard independently, and the Trident also offers a flanger effect along with a joystick for pitch bending and modulation.

OverviewKorg's Trident, released in 1980, combined polyphonic synthesis, brass sounds, and string ensemble in a single programmable instrument. This 8-voice polyphonic synthesizer offered three distinct sections—synthesizer, brass, and strings—that could be layered for complex textures. The Trident represented early workstation concepts, integrating multiple sound sources.
The instrument featured dual VCOs per voice, a resonant low-pass filter, and comprehensive envelope generators. The 61-key keyboard and 16 patch memories supported professional performance. The Trident's size and weight reflected its comprehensive architecture.
Korg produced the Trident and the enhanced Trident II through 1982. The instrument influenced subsequent Korg workstations and demonstrated the market for integrated keyboard instruments. The Trident remains collectible for its unique combination of sounds and historical significance.
