Korg DeltaReleased in 1979
The Delta DL-50 is a 49-note paraphonic string machine/synthesizer, and strings can be layered with the synth for a really nice sound. It is much more than a slimmed-down version of the Trident. Boasting deep bass and a fully polyphonic string section with separate outputs, achieving classic layered sounds is easy. It has independent envelopes for the string and synth sections, 24dB resonant low-pass and band-pass filter, built in equalizer, CV connectivity and even a joystick! The Korg Delta is a true classic.
