The soundfont was sampled using some websites/web apps that offer an animated drumset with different arrangements of key controls to play the kick, hats, snare, toms and cymbals. I'm so slow to adapt these custom maps, so I decided to slap the samples to the classic GM/GS drum map and finally layered the rest of percussion. Not only that but also I added a missing China cymbal from Milton Paredes' Just T4, which kinda fits neat with it.
Some samples from my ColomboGMGS2 soundfont (Percussion, Mostly, all the way from Eric Hermansen's Industromatic V1.0 and Basement Noises soundfonts) and other pipe sounds were used here. Mainly the actual pipe sound by @ThatTechGuy2007 on YouTube shorts and some random compilation of "ASMR Good For Sleeping" something pipe sounds compilation.
