The Korg Monologue is a compact, full-featured analog monosynth with a 25-key keyboard, built-in sequencer, and micro-tuning support. It offers two VCOs, a classic Korg filter, drive circuit, and 16-step motion sequencer for recording parameter automation. With its solid metal chassis, battery or AC power options, and direct hands-on controls, it’s a versatile tool for basslines, leads, and experimental sound design.
