Korg Volca Drum - Digital Percussion Synthesizer
The Korg Volca Drum is a digital percussion synthesizer
 that harnesses the power of physical modeling to create sounds and 
patterns unlike most other drum machines, making it well suited for 
musicians and producers working in the studio or performing live on 
stage. The machine utilizes dual-layer drum parts, comprehensive motion 
sequencing, and sequencer tricks to generate a variety of standard 
percussive sounds and eccentric drum styles.
The Volca Drum provides six parts, each with two layers, from which the 
user selects any one of 5 oscillator waveforms including sine, sawtooth,
 and HPF noise. Additionally, the user can select from three types of 
pitch modulators and amplifier envelope generators, each optimized for 
drum sounds. Edit layers separately or together while adding bit 
reduction, wave-folder depth, overdrive, and distortion. A waveguide 
resonator adds sympathetic resonances to the sound and provides two 
selected types including tube, which adds the resonance of a cylindrical
 object such as a drum body or a long pipe; or strings, which adds the 
metallic resonance of a string.
The onboard step-sequencer allows the user to manually input up to 16 
steps per pattern, but also can be used for real-time recording. The 
pattern chaining function can chain up to 16 sequences to construct 
patterns with up to 256 steps. Use the motion sequence function to 
record knob movements during real-time recording and reproduce them 
during playback. There are a total of 69 different parameters that can 
be recorded and played back. Additional features and functions include 
Active Step, which replaces steps for each part; and Slice, which finely
 divides a step to allow drum-rolls; an Accent function that can be 
specified in 16 levels; and a convenient Choke function for specific 
grouping of parts.
The Volca Drum can be synchronized with other Volcas and Electribes via 
the trigger I/O. Additionally, the machine features a standard 5-pin DIN
 connector for connecting to other sequencers, allowing the unit to 
perform as a drum module. The Korg Volca Drum is powered by an optional 
power supply or via the included six AA batteries.
