Hello! It’s been a while since I shared anything. I made this song just about a year ago, right before I started spending more time on Sonic Pi using MIDI. I’ve recently come back to the synth/sample stuff I was working on to render it out in multiple tracks and mix it in Ardour.
This is more or less all Sonic Pi with some EQ and wave edit cleanup, the one exception being a different Amen sample. I was looking at the sample that comes with Sonic Pi and noticed that it’s clipped, and while there may be some tradition to a highly overdriven version, I wanted a clean Amen so that the bit crusher posed an even greater contrast to the cleaner break.
So I went to my trusty massive stash of old school breaks and sought out the Winstons. There are some differences between the original full Amen and the one most commonly used in music production. First thing is that the original version starts with a note stab, so most versions use the second measure twice to start out. Also it’s been typically quantized to make it friendlier to note choppers. That would be Detrimental to the likes of Tom Jenkinson, but the average human does better with some quantization. I used Ardour and split the beats by hand, shrinking by overlap, but stretching up to 10% on short hits when absolutely necessary. So it’s not a sample perfect recreation, but at most it phases beside the original. Only the most hardcore junglist tweaker should be able to hear the quantization difference when used for DnB tempos or above. Also, because the hats are a lot quieter than the kick and snare, I gave it a little bit of compression. If I give it enough to sound the right volume in the chopper, it’s sounds unnatural as a loop, so I compromised in the middle. Compress it another 3-6 dB to taste if you like, as I have provided this sample along with the Recording of the song. You can find both here. https://drive.google.com/open?id=15xvyJEdbut-DYOkTMKn4mn_g-hwtj5G8
It wouldn’t be sonic pi if I didn’t share the code. Right now I want to just focus on sharing the drum code with y’all and let you try whatever you like with it. Once I get my album out (I’m in the recording and mixing stage), I will release full, annotated source to accompany it with a link back to Sonic Pi and this community.

…And yes it’s so intentionally a Venetian Snares style homage that I accidentally call it Detrimentalist sometimes Hope someone finds this useful!
