Volca Keys packs true analog synthesis into Korg's smallest hardware format — a 27-key touch keyboard sitting over three voltage-controlled oscillators, one filter, one amp, and one envelope generator, with a filter circuit borrowed directly from the legendary 1974 miniKORG 700S. It's paraphonic up to three notes, enough for chords and lead lines without pretending to be a full polysynth.

A built-in delay effect and 16-step loop sequencer with eight storable patterns cover composition without a computer attached, and Motion Sequence records live knob tweaks into the loop for evolving textures. Battery power and a built-in speaker mean it's playable anywhere, no studio required.
