The Korg Prologue 8 is a professional-grade 49-key analog synthesizer offering eight voices of polyphony, dual VCOs, a digital multi-engine, and built-in DSP effects. Combining analog warmth with digital flexibility, it features a bi-timbral architecture, studio-quality reverb and delay, and a user-customizable oscillator section that supports third-party development. Its powerful 16-slot modulation matrix, OLED oscilloscope, and aluminum and wood construction make it both a performance-ready synth and a deep sound design tool. This unit is in excellent condition and ready to anchor any stage or studio setup.
