EMS Synthi 100 Oscillographics [Radio Belgrade Electronic Studio]

EMS Synthi 100 Oscillographics [Radio Belgrade Electronic Studio] from macumbista on Vimeo.

"This is a series of audiovisual X/Y oscilloscope patches for the EMS Synthi 100 at the Radio Belgrade Electronic Music Studio, and visualized on the Tektronix 5000 series modular rack oscilloscope. They were programmed to run autonomously without any human control. Most of them use two or three oscillators tuned to a close harmonic, and small changes in the frequencies (including temperature drift!) will make large changes in the image/sound. A couple use the Synthi 100's low pass filters as well. All are based on Ron Pellegrino's laser designs from "The Electronic Arts of Sound and Light" (1983)."

"This is an audiovisual X/Y oscilloscope patch designed for the EMS Synthi 100 at the Radio Belgrade Electronic Music Studio and visualized on the Tektronix 5000 series modular rack oscilloscope. OSC 1 serves a visual purpose mainly and can be adjusted freely. OSC 2 provides the fundamental of the image/sound. OSC 10 sweeps FIL 2 through the harmonics and adds or subtracts nodes from the visual figure. Based on Ron Pellegrino's "Laser design 6", The Electronic Arts of Sound and Light (1983). NOTE: for X/Y display, replace "Time Base/Ampl" module on oscilloscope with "Y2" module.
