The Korg Volca Keys is a three-voice polyphonic analog synthesizer in the compact Volca form factor. It produces pads, leads, and textural loops from three analog VCOs with detune, ring modulation, and portamento. A built-in analog delay effect adds space and depth. The 16-step sequencer and touch keyboard make it a self-contained musical instrument that runs on batteries. Analog Sound Engine Three VCOs with sawtooth and square waveforms, tuneable in octave steps with detune and ring modulation. A 12 dB/oct low-pass filter with cutoff, resonance, and envelope intensity shapes the tone. One LFO modulates pitch and cutoff with sawtooth, triangle, or square waveforms. An analog delay effect with time, feedback, and tempo sync adds depth.
