Digital percussion synth with a 6-part x 2-layer structure

The term "digital" typically brings to mind sounds that are based on PCM-sampled bass drum, snare drum, or cymbal, but the volca drum creates its drum sounds by DSP-powered analog modeling. Oscillator waveforms such as sine wave, sawtooth wave, and noise are provided. By applying various changes to these waveforms, you can create a wide variety of percussion sounds that range from realistic to idiosyncratic, and are not limited only to drums.

The six parts each have two layers, and do not impose any rules or restrictions such as specifying which parts must be used for the bass drum or for the cymbal; all parts have the same specifications. You can freely assign your new sounds to these six parts without being limited by the conventions of a drum set. A kit consists of the six parts that you've assigned plus the waveguide resonator effect settings, and 16 such kits can be stored in memory (the factory settings contain 10 preload kits).

Distinctive sound from a newly developed DSP engine

Each part consists of two layers. For each layer, users choose one of five types of oscillator waveform including sine wave, sawtooth wave, and HPF noise, and also choose from three types of pitch modulator and amp EG, each optimized for drum sounds. Layer parameters can be edited either individually or simultaneously, and users can also use the two layers to produce the same sound for additional thickness.

You can customize the resulting trigger waveform by applying bit reduction to produce roughness, adjusting the wave folder depth to add complex overtones, and using overdrive to adjust the distortion. In this way, you can generate distinctive sounds from this sound engine that's structured rather differently from a typical drum machine.

Once you've specified the sound, you can adjust the balance of the parts by modifying the timing at which steps are heard, the pan, the gain before mixing, and the effect sends.

Waveguide resonator adds rich resonances

The effect section features a waveguide resonator that's based on physical modeling, and which adds sympathetic resonances to the sound. You can choose from two types of waveguide: "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 three knobs located in the center of the panel let you specify the DECAY (amount of attenuation), BODY (sonic character), and TUNE (pitch). Setting TUNE to a lower value will produce a delay-like behavior. You can take advantage of these knobs not only for sound design but also in your live performances.

16-step sequencer with a wide range of parameter automation

The 16-step sequencer is excellent for improvisation. You can easily create patterns using the 16 buttons, each corresponding to one of the 16 steps. In addition to step recording, the sequencer also supports realtime recording in which you can construct a pattern while looping the playback. The pattern chain function lets you play multiple sequence patterns successively, so you can successively play back desired patterns of consecutive numbers. Up to 16 sequences can be connected to construct patterns with 256 steps.

In addition to simply playing a drum pattern, you can use the motion sequence function to memorize knob operations during realtime recording and reproduce them during playback; a total of 69 different parameters can be memorized. This is useful not only when you're creating your patterns, but can also contribute to live performances that overflow with originality. Up to 16 sequence programs (16-step sequencer patterns, stored motion sequences, kit number) can be saved in internal memory.
