Program Notes

“Looking at the map, we view ourselves from above. Abstracted from time, the map suggests our terrain to be permanent and unchanging. We define our locations by the things that surround us, but our relations to geographical reference points have become increasingly distant and vague. Some 20,000km overhead, GPS satellites form fleeting trios, constructing my position and my course“



Technical Notes

GPS satellites transmit psuedo-random binary encoded into phase alternations, 0 being 0° and 1 being 180°. The sounds for this piece were created by applying this method to ssynthesis, realized in VCV Rack, with random binary generated via Mutable Instruments’ Branches module. These sounds were then performed using audio, with 3 floors of a stairwell each containing it’s own “satellite.”
