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. 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. This is also an ideal beginner's instrument for learning the enjoyment of creating your own sounds.
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.
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.
