One sample run through lots of effects, but a large part of the sound is made by running the sample at really fast repetitions, so fast it just becomes a tone. That and making the sound repeat in fractions (?) or something like that. Like one trigger is 5 times and then the next is 3 times in the same space of time. Etc. Created by mangling a sample in reaper's js scripting language.
