I figure I could do some due diligence and see what comes up in a google search.
I found a reddit post from about 6 months ago on r/aphextwin where OP asked what drum sounds he used on minipop (i actually forgot he had named a song after this piece of gear) and u/Vreature generously replied:
Snare
That snare is mostly white noise which is different from pink noise. White noise is a random signal that is equal volume across the entire frequency spectrum. Pink noise is a random signal that is equal volume across all octaves. The way we perceive sound makes Pink noise sound dull and low energy. White noise, like static on the radio, sounds higher energy and like I said it fills out the entire frequency spectrum, quite literally making the mix dense. Being Aphex Twin, he masterfully plays with cutting it off abruptly and turning it back on in all kinds of cool patterns.
There is a thick reverb on the snare. The tail of the reverb “slaps-back”. This means the reverb trails off in volume but then before it ends, it comes back to the forefront of the mix. When the volume shoots back up, it does so rhythmically and fills out the frequency spectrum where the snare was previously.
Kick
The kick is bigger and beefier than most of his kick drums, meaning it’s got some extra volume on the second octave above the root note. People usually take this out because it sounds muddy. It doesn’t sound muddy in Minipops because he’s an elite sound designer. Dense.
Shaker/Tambo
But most of all, it’s the tambourine/shaker/hi hat sound. Usually Aphex’s hi-hats are short little clicks. In This track, they are directly in the foreground, and they are and drawn out. There is a heavy amount of “swing” to them, meaning they are heavily syncopated. Syncopated means they are “off the grid”. They don’t land on the 1/8 or 1/16th notes, they land in between them. This fills out the spaces in between the main pulses; kick and snare. Again, this is mostly white noise which fills out the spectrum. Dense.
Fanfare
Then of course, he’s got what I call fan-fare. Fan-fare to me is all the other interesting percussive sounds that pop up out of nowhere adding all kinds of interest. Bongos and weird analog drum sounds.
Ride
Then there is the acid breakdown where the ride cymbal is in the loudest thing in the mix which is somewhat unusual for him. He does a similar thing in the first half of Omgyjya Switch 7, which on the whole has the same type of drum pallet.
Bass
The midrange of the analog synth bass is heavily filtered out, which gives space for the drums and makes them sound more prevalent.
I know the descriptions here are specifically in reference this one song, but it’s as good a jumping off point as any.
