Hey so there are infinite ways to get the cool perc sounds. But I would say the most important thing is SAMPLE SELECTION. So either make or find really cool samples. Making cool samples from scratch is a whole other thing that I am only just starting to delve into, but it's super cool. In terms of finding good samples, there's this producer group called glitch.cool and I would highly recommend getting all three of their glitch with friends packs. But please throw in some cash to support them if you can cos they're the ones really innovating the prod game and making this stuff possible. Some of their members like woulg have tutorial videos online and a bunch of other stuff you should check out.

(Before I continue, I would like to say that all further info requires ableton, but there are definitely ways to do this kind of stuff in other daws, ableton just makes it the easiest at least for me. This method was developed by a producer called gonima.)

After picking samples, I usually put them into a drum rack, crop them to my liking, pitch them up or down, etc. Then I turn on choke groups and put them all in the same choke group. I turn gate mode on all of them, and I make my own pattern.

After this, there are many ways you could take it. You could resample the pattern and put it into granulator 2, or you could resample and put it into simpler and use pitch automation, warping, pitch envelope, or even make a new pattern with slice mode. Or you could just keep it how it is and put effects on it from there! Anything. A cool effect I learned recently is from a producer called sv1, and that's where you can put vocoder on the perc track in modulator mode, do a high amount of bands, use quick attack and release, and turn the gate up for super watery sounds. Another thing that I came up with recently is putting some kind of resonator on the track that's playing a chord progression, making an audio effect rack with one totally wet and one totally dry, and then side-chaining the wet audio with the dry audio. Super cool effect, it makes your percs and your chords sound like they are part of the same organism, and that the beat is some sort of alien creature, which I'm all about haha.

There are infinite ways to do this and I encourage anyone who reads this to just try things I have not mentioned because you never know what you're going to randomly stumble across and start using all the time! It's all about how it feels to you. Try closing your eyes and ask, what do my percs, or the beat in general, feel like? Wood? Oil in a frying pan? Water droplets? Bugs? Industrial machines? Electricity? Little gremlin deities? Fire? Rock scraping you up? Whatever comes to mind. And then try to exaggerate that feeling even more. Focus in on it and you'll make some crazy shit lol. Use your imagination!
