LAMBDA ES50 (1979) BY KORG INC.
The Lambda ES50 was a 48-key polyphonic synthesizer released by Korg in 1979. It used divide-down technology to produce its polyphony. It featured two types of preset sound: Percussive (Electric Piano, Clavi, Piano, Harmonics) and Ensemble (Brass, Organ, Choir, Strings I, Strings II). The Percussive sounds had a simple fast attack and variable decay envelope, and the Ensemble sounds had both preset and variable attack/release envelopes. The Lambda had limitied programmability, but the presets sounded good and they were all available simultaneously.
The above model was made in Lightwave 3D. The model and texture files are available for download here:
