1987 vintage Korg DS-8 Digital Synth, 61 key, 100 editable presets, plus extra DS series library card. It is a digital FM synthesizer with 4-operators per voice, 8 voices of polyphony and 8 parts multitimbrality. It's good for electric pianos, percussive, strange effect noises and such because its sound is so unique. It has some digital effects such as chorus, flange, delay and analog-like controls for modulators, envelopes and the LFO. A joystick provides control of modulation and pitch bending. It also has a performance section for quick edits on the fly using (3) real-time sliders to control timbre, EG1 and EG2.
