Critic Reviews

SIGMA ENIGMA

soundonsound.com

The Korg Sigma, a quirky blend of home-organ aesthetics and synthesizer functionality, struggles with an identity crisis. Its charm lies in the unconventional control layout and intriguing performance features, such as dual joysticks and aftertouch sensitivity. However, it falls short with its limited sound sculpting options and lack of filter resonance control. While it offers unique sound combinations and nostalgic presets, its dated design and "nasal" timbre may not satisfy modern synth enthusiasts. Ultimately, the Sigma is a niche choice, appealing to those seeking its specific vintage character rather than versatility or depth.
