The Korg Volca Keys is a compact analog lead synthesizer with 27 keys and a polyphonic sound engine. It has three voices and a built-in loop sequencer and delay effect. Its filter section uses the circuitry of the miniKORG700S (1974).
The structure is 3 VCO, 1 VCF, 1 VCA, 1 LFO, and 1 EG. The three oscillators can play chords, run in unison with detune for lead lines, or use ring modulation for metallic sounds. A Voicing knob selects how the oscillators combine: Poly, Unison, Octave, Fifth, Unison Ring, or Poly Ring. The delay effect also reproduces the pitch change heard when the delay time is changed on an analog tape echo unit.
The loop sequencer records phrases as they are played. The Motion Sequence function is used to refine loops, and the Active Step and Flux functions add change to sequences. A self-tuning function corrects pitch drift. The SYNC jack and MIDI IN connector allow synchronized performance with multiple units or a DAW. The Volca Keys runs on batteries and has a built-in speaker. It is part of the Volca series, alongside the Volca Bass and Volca Beats.
