Simple Colour Organ is a visually engaging plugin designed to translate musical notes into specific colors, inspired by historical concepts from figures like Father Louis Bertrand Castel and A. Wallace Rimington. Rather than producing sound, this plugin offers a unique visual experience where pressing a key triggers the display of corresponding colors, effectively turning music into dynamic light displays. It provides an innovative way to explore the relationship between sound and color within a digital audio environment.

The plugin includes seven distinct color palettes, six of which are based on the original schemes developed by Castel, Rimington, and Alexander Scriabin, while the seventh is a custom pastel palette created for a softer visual effect. Users have the flexibility to add their own palettes, enhancing customization. Switching between palettes is seamless and can be done in real time using simple mouse controls, allowing for smooth transitions and varied visual interpretations during performance or production.

Beyond its core visual features, Simple Colour Organ offers two automation-accessible parameters that control the attack and delay of the color envelope, enabling users to shape how colors appear and fade in response to notes. This adds a layer of expressive control, making the plugin adaptable to different artistic contexts. Simple Colour Organ is an ideal tool for musicians and producers seeking to incorporate color as a complementary element to their sound design and compositions.
