The Volca Keys is an analogue synthesizer manufactured by the Japanese music technology company Korg.

The Volca Keys uses subtractive synthesis to create sounds and is three-note paraphonic, meaning that it can play chords with all voices sharing a single voltage-controlled filter (VCF).

At the time of its release, it filled the niche of an affordable analogue synthesizer, which contributed to its success.

MusicTech stated, "Korg has listened to its customers and managed to hit the perfect balance of price and features"[3] and Future Music seemed to agree, saying that "the Volca synth is revolutionary at this price point" and suggesting that "everybody should own one".

[3] The knobs on the front are made of transparent and solid plastic and are similar to those on Korg's Monotron, although the build quality is improved.

[1] Connections on the Volca Keys include MIDI in, sync in/out and 9V DC power input.

Controls over oscillator pitch, detune, portamento (glide) and envelope intensity are available.

[5] Modulation on the Volca Keys comes from two sources, an ASR envelope generator and low-frequency oscillator (LFO).
