Waldian
Waldian is a standalone, wall hanging sound and light fixture capable of playing a near infinite amount of melodic permutations over a predetermined musical scale, complemented by emerging light patterns from twelve separate LEDs spread across the sculpture. In technical terms, Waldian contains two oscillators, an envelope generator and a voltage controlled amplifier, all controlled by impulses from a network of logic gates akin to those of early computers. These impulses are essentially the nerves in the electronic ecosystem, deciding over pitch and amplitude changes as well as creating bursts of light to highlight the entrances of each note. Finally, there is a tube overdrive stage that creates harmonic and subharmonics based on how far away the two oscillators are from each other in frequency. Most parameters are customizable, such as the aforementioned pitch, amplitude and overdrive, but the responsiveness and envelope of the light bursts can also be adjusted, directly affecting the appearance of the light patterns.
