The ideal introductory synthesizer, with a simple – yet powerful – polyphonic analog sound engine and loop sequencer The polyphonic synthesizer you've been waiting for Three note true analogue synthesis Voicing function lets anyone create sounds easily Delay effect for even more sonic possibilities Simple loop sequencer Loop sequencer lets you record phases just as you play them Motion Sequencer records knob edits in real time Active Step function and Flux function to add dynamic change to your sequences Convenient functions for tremendous ease of use Self-tuning function for constant, stable pitch Sync In and Out allows clock sync of multiple instruments from the volca Series as well as Korg's Monotribe Compact size, battery-powered operation, and built-in speaker for enjoyment anywhere Volca Keys is a long-awaited synthesizer that adds a new chapter to the long and storied history of Korg's analog synthesizers. This 27-key analog lead synth delivers unbelievably powerful sound in a compact body. Starting with a filter section that uses the circuitry of the legendary miniKORG700S (1974), it delivers astonishing sound that takes full advantage of Korg's half-century of know-how in circuit design. With a simple structure that includes delay effect and a sequencer, it's also an ideal choice for a first analog synth. It offers the richly expressive sounds that are distinctive of analog, providing the enjoyment of simple yet deep sound-creation. The possibilities are endless; you can use the three oscillators to play chords, use them in unison with detune to produce solid lead lines, or apply ring modulation to create far-out metallic sounds.
