There’s a synthesizer module called the Endless Processor made by the company Blukač, which is based in Ukraine. The Endless Processor uses various techniques, including what’s called granular synthesis, to achieve a “clickless stream while preserving the timbral and tonal character of the original” source audio that is fed into it. The result is quite beautiful. You send the Endless something and it captures a brief moment (details at blukac.com), which it can then hold indefinitely. There are numerous devices that accomplish similar end results, each with its own sonic qualities, and the Endless has caused several musicians I follow to explore and document its inherent characteristics.
A musician going by the name Olio, who is from Trentino-South Tyrol in Italy, released an eight-track set of quavering drones of varying types, simply titled Endless:
And Ras Thavas, based in California, produced three tracks that constitute Endless Processor Studies, including a 20-minute one you can really get lost in:
Settle into both albums and listen for the hallmarks — the watermark — of the Blukač Endless Processor. In effect, while the Endless synthesizer module was designed to identify and hold the tonal qualities of a specific moment in time, musicians like Olio and Ras Thavas are helping identify and hold the tonal qualities of the device itself.
