Here’s another cool project from Kyle Evans, creator of the electroacoustic didgeridoo.
The de/Rastra oscillographic synthesizer is a real-time audio/video instrument and computer-interfacing device that lets you generate visualizations intrinsic to cathode ray tube technology while simultaneously creating the acoustic analog of the displayed imagery.
Here’s what Evans has to say about the de/Rastra oscillographic synthesizer:
Through hacking and exploiting the capabilities intrinsic to all CRT devices, the technology becomes repurposed as a performative interface, breaking down the device’s ‘consumption only’ nature. The performer is given control over the technology by removing it from the intended application and forcing it into an active state through a combination of physical and mental effort.
