Korg Volca Keys Analog Synthesizer Simple three-voice polyphonic analog synthesizer - With its structure of 3VCO, 1VCF, 1VCA, 1LFO, and 1EG, the volca keys has a recognizable, versatile structure. The ability to generate diverse and powerful sounds with just a few carefully selected parameters is a distinctive characteristic of analog synthesizers. Voicing function lets anyone create sounds easily - The Voicing function makes it easy to specify how the three oscillators will be combined. Simply turn the knob to choose one of six combinations: Poly, Unison, Octave, Fifth, Unison Ring, or Poly Ring. Without complicating the volca's simple design, this feature makes it easy to obtain a wide variety of sounds. Delay effect for even more sonic possibilities - The volca keys contains a delay effect that's indispensable for creating spacey synthesizer sounds. This effect also reproduces the pitch change that occurs when you change the delay time on an analog tape echo unit. Loop sequencer lets you record phrases just as you play them - There's a loop sequencer with up to 16 steps, allowing you to record your performance on the touch panel keyboard just as you play. It's easy to create phrases that come to mind, and you can also use overdub recording to produce complex loops that could not be played individually. Up to eight sequence patterns can be stored in internal memory. Use the Motion Sequence function to meticulously craft your loops - The Motion Sequence function lets you record knob movements, letting you apply time-varying changes to your sound that will enhance your loops and add originality to your live performances.
