The instrument
The Korg LP-10, released in 1980, is an analog electric piano with 61 keys. It offers divide-down synthesis for polyphony, an attack-decay envelope, a chorus, decay, sustain and the voices piano, organ and harpsichord, which can be combined. There’s also a 6-band graphic equalizer for shaping the sound, compatible with a sustain pedal. (Korg manual)
