音光 (Onkou) - Light Controller for Modular Synthesizer (Breakbeat Demo)

Published on Mar 31, 2018 Takumi Ogata

"音光 (Onkou) is a light controller for Eurorack modular synthesizer system. The module has a camera that can detect X, Y, and Z positions as well as the hue color of the light. Each of these 4 parameters are mapped to a control voltage (4 separate control voltage outputs). The custom light source consists of on/off button, a knob for controlling the hue of the light, and a switch that is used to go back and forth between auto and manual mode. In auto-mode, the module takes in two separate control voltage inputs and send on/off and hue messages to the light source via bluetooth. In this demo video, wavetable control voltage from Qu-Bit Chance module is used to randomly change the hue color and sequenced gate control voltage is used for the light’s on/off pattern.

Hardware/Software used:
Make Noise Morphagene = main sound source controlled by the light controller
Qu-Bit Chance = random control voltage for light hue control
Make Noise Tempi = On/off message for the light
Ableton Live
