My point was not to snark about granular synthesis; my point was to demonstrate the amount of freedom that exists in synthesis methods that have been around for a long time. I understand the criticism that a lot of music is stuck in 12-tone equal temperament, I don't understand the idea that electronic music as a whole is stuck there.
I actually have no idea what telemetry is supposed to sound like but I think this guy was just making bad music, with granular synthesis. Granular synthesis can actually be quite beautiful and tonal if thats what you're looking for, see examples [1] and [2] just to dig up some quick examples. Ableton's built-in time stretching uses granular synthesis. One guy's bad granular music isn't really indicative of anything.
