The CV to Video box is an analog to digital converter for my audio visual performances. It enables me to use the control voltages signals of my modular synthesizers to control custom made video oriented patches in Pure Data or in Processing. It uses an Arduino Mega and some R2R analog to digital converters in order to acquire the signals.
It is an ongoing prototype that evolved a lot over time. Next revision will be standalone, using a raspberry pi to host the video generation program. Hopefully, it will one day by turned into a Eurorack module from Ritual Electronics.
