An versatile micro bass synth featuring fat analog sounds and Electribe-inspired sequencer to rule the low end of your music

Korg’s Volca Bass synthesizer takes you back to the ’80s, when synthesizers displaced guitars as the primary instrument of popular music, and bass ruled the low end. It was because of synthesizers such as the Korg x which the Volca Bass descends from, that bass guitar makers started adding five and six strings to compete with the low-end capabilities of the synths. Taking its cues from the classic Korg MS-10 and MS-20, the Volca Bass has what you need for a wide range of bass lines. Simple in design and execution, yet highly musical to use, Volca Bass features an analog sound engine that offers low-frequency presence and nuance that can’t be reproduced by digital emulations. The Volca Bass also features a step sequencer derived from the famed Korg Electribe—a powerful way to generate free-form bass loops.

Korg Volca Bass synthesizer in one take:

  • Three oscillators generate a variety of bass sounds
  • Bright, crisp sound from Korg’s legendary analog filter
  • 3-part, 16-step sequencer derived from the famed Korg Electribe
  • Self-tuning function
  • Sync jack and MIDI In, battery-powered operation, and built-in speaker

INSIDE THE BOX—Korg Volca Bass

Three oscillators generate a variety of bass sounds

The Volca Bass features three oscillators that can be used in a variety of ways, from one-part unison to three-part chords, giving you a diverse array of thick and modulated bass sounds. By creating a sequence that uses each oscillator individually, you can create a complex pattern in which three different phrases are woven together. Using the oscillators in a 2+1 combination lets you place one set of oscillators at a low pitch and the other at a higher pitch, producing simultaneous bass and melody lines. When using the three oscillators together, you can slightly detune their pitch to generate thick unison sounds. Setting the oscillator’s pitch to 0, +3, and +7 will produce a chord.

Bright, crisp sound from Korg’s legendary analog filter

The Volca Bass features a finely tuned analog filter. Turning the Cutoff knob to open the filter will make the sound brighter and more expansive; closing the filter produces a round, milder sound. Using the Peak knob to increase resonance will initially produce a clean peak, while further increases will create a great-sounding distortion. The Volca Beat’s resonance distortion, an essential component of acid music, has been specially tuned to enhance bass sounds.

Simple structure with a single VCF, VCA, LFO, and EG

In addition to the three VCOs (voltage controlled oscillators), the Volca Bass provides a carefully selected parameter structure consisting of a single VCF (voltage-controlled filter), VCA (voltage-controlled amplifier), LFO (low-frequency oscillator), and EG (envelope generator), ensuring that the sound that you want can be created with a little creative tweaking. This is also the standard structure of a synthesizer, making the Volca Bass an ideal introductory instrument for learning the fundamentals of synthesis, so beginners can experience the joy of sound design.

 Loop sequencer derived from the Korg Electribe

 The Volca Bass step sequencer is designed to make editing easy and to let you add or remove parts in an improvisational fashion. You can use its 16 step keys to enter notes while visually monitoring the timing of the notes within the measure. You can also enter completely different phrases for each of the three oscillators, and play the touch panel keyboard to record in real time. Up to eight patterns can be stored in internal memory. The volca bass provides Slide function that creates the impression of connected steps for moving bass lines, which make it easy for anyone to produce acid sounds. The slide can be specified for each step. The Volca Bass sequencer also has an Active Step function that lets you skip a step during sequence playback. It can create effects similar to a short loop, or unexpectedly irregular rhythms, allowing dynamic performances as though you were performing the sequence live.

 Self-tuning function

While we all enjoy the rich sound of analog synthesizers, the one downside was that pitch would drift with changes in temperature or the passage of time. The Volca Bass solves analog pitch drift by providing a Self-tuning function that constantly tunes the oscillators. You’ll never need to tune during a performance, or wait for the pitch to stabilize after turning the power on.


Sync jack and MIDI In

Other performance features of the Volca Bass include a sync jack for synchronized playback with multiple Volcas or a monotribe. The MIDI In connector also lets you synchronize with other devices, as well as play the Volca from a MIDI keyboard or send note messages from your DAW to use the Volca Bass as an analog sound module.

You can also use the “SyncKontrol” iPhone app to wirelessly control tap tempo, swing settings, and synchronized playback with iOS music apps via Korg’s WIST (Wireless Sync-Start Technology).

Battery-powered operation and built-in speaker

With its compact size, battery operation, and built-in speaker, it’s easy to take the Volca anywhere. It can sit on a small DJ coffin while creating huge sounds. Or you can ascend to a mountain peak, view the firmament, and serenade the local villagers with Volca bass lines.
