Korg Volca Modular Semi-Modular Analog Synthesizer with 16-Step Sequencer

Volca Modular - Micro Modular Synthesizer

A semi-modular analog synthesizer that makes modular synthesis more accessible and understandable than ever before.

Creating new sounds that don’t exist in the outside world is an unending dream which has continued since the birth of electronic musical instruments. This dream has evolved and expanded throughout the development of new and unique music production devices.

The popularity of modular synthesizers around the world has generated new excitement and interest in the so-called "West Coast style" of synthesis that deviates from traditional synthesis norms.

The compact body of this volca synth features eight modules and 50 patch points. While learning the basics of a modular synth, you can use popular features of the volca synthesizer line to control a unique and different flavor of analog sounds.


An analog synth composed of modules

Eight modules

The volca modular is a semi-modular synthesizer consisting of independent analog synth modules, digital effects, and a sequencer. Each of the modules has been carefully selected for its stand-alone completeness. The modules are internally connected so that sound can be produced even before connecting the included pin cables, and the routing is shown by white lines on the panel. Module connections via a pin cable take priority over the internal connections, bypassing them.


A fusion of West Coast style in a volca format

Analog synthesizers in which a simple oscillator such as a saw wave or square wave is modified by a filter are referred to as "East Coast style" because of their origin from well-known American manufacturers. Synths of this style, as exemplified by the MS-20, have continued to evolve toward a goal of being used in many mainstream musical genres, thus being equipped with a keyboard for performance. Their sounds are notable for sharp filters and rich presence, and can be heard in many well-known songs.

Synthesizers of the "West Coast style" evolved in a uniquely different direction from such musical developments. Pursuing the freedom that is inherent to electronic musical instruments, these were based on oscillators such as FM modulation which generated numerous overtones, and used random and complex control signals and low-pass gate circuits to vary tonal character and volume, so that slight movement of a knob might dramatically transform the sound. While their potential was acknowledged, the resulting sound and its changes were difficult to predict, causing these synths to be used in a more experimental capacity.

For these reasons, hardware products of this style have been few in number. However, recent years have seen the popularity of modular synths such as Eurorack, as well as DAW plugin instruments that resurrect classic bygone synths of the past. This world-wide movement toward embracing interesting sounds has received renewed attention, spurring a new look at the sounds of this style.

Starting from analog, and freely taking in all elements including FM and PCM, the volca series has also focused on this trend. And now, this distinctive "West Coast style" sound has been added to the KORG volca series.


Volca sequencer elevates experimental sounds into music

Sixteen-step sequencer that can automate parameters

While the volca modular is a semi-modular synth, it is equipped with a full-fledged 16-step sequencer providing a wide range of functions, letting you enjoy automatic performance even when used stand-alone.

Using the 16 buttons familiar from the volca series, you can perform step input or use the buttons as a keyboard for realtime recording. The pattern chaining function plays back multiple sequence patterns in succession, allowing you to connect up to 16 sequences with up to 32, 64, or even 256 steps to create large-scale development.

The motion sequence function records knob movements, letting you add time-varying change to the sound. You can create loops, or use this function live for strikingly original performances. Up to 16 sequence patterns and sounds can be saved in the unit.

Also provided is an active step function which lets you play back while skipping the steps you specify. You can skip the latter half to produce a short loop, use an alternate time signature to create polyrhythms, and evolve sequence patterns in real time to create a dynamic performance.
