The Volca Modular is an analogue synthesizer[b] manufactured by the Japanese music technology company Korg.

[1] Volca Modular was released ahead Winter NAMM in February 2019,[3][4] although information and pictures were leaked in December 2018.

[1][2] The Volca Modular was inspired by the "West Coast" design of synthesizers, produced by the likes of Don Buchla and Serge Tcherepnin in the 60s and 70s.

West Coast synthesizers were based around the idea of adding harmonics to simple waveforms using complex oscillator cores and wavefolding,[9] unlike the filtering of high harmonic waves used by the contemporary "East Coast" pioneer Robert Moog.

[10] The Volca Modular's colour palette is also inspired by the Serge-Buchla synthesizers, with their iconic red, white and blue livery.

Of all the Serge-Buchla synthesizers, the Volca Modular is most similar to the Buchla Music Easel in terms of modules and capabilities.

It features a triangle-wave based complex oscillator core, dual low pass gates, function generators and a source of uncertainty (Sample and hold).

[12][13] The Volca Modular has of 8 distinct modules, with a total of 50 patch points[d] available to be connected:[10][14] The oscillator section contains a two VCOs that can only produce a triangle wave.

The other function generator on the Volca Modular is ramp shaped, with no control over the individual portions of the envelope.

[15] The Utility module uses two simple equations to attenuate and mix signals: a+b*c and a-b*c (where c is the knob marked "c").
