Korg Volca Keys is a 27-key monophonic synthesizer that produces an incredibly powerful sound despite its compact body. We started with a filter section that uses the circuit from the legendary miniKORG700S (1974). With a simple layout that includes delay effect and a sequencer, it is the ideal choice as a first analog synthesizer. It offers the rich and expressive sounds typical of an analog synth for a powerful yet very easy-to-use sonic experience.
