Volca Drum is a digital percussion synthesizer with a 6-part x 2-layer structure. Using DSP-powered analog modelling, it creates a wide range of unique sounds with wave folder, overdrive, and waveguide resonator effects. The 16-step sequencer supports realtime recording and motion sequencing, with features like active step, slice function, accent function, and choke function for dynamic pattern creation. Compact, battery-operated design allows for portability.
