If you don’t mind saying, what kind of tools do you use? (I’m pretty ignorant about electronic music production, but I’ve played around a bit with VCV Rack and some of the emulators on roland50.studio.)

Almost the entire song was created on the computer. The digital audio workstation used was Reaper; the synth sounds came from Zynaddsubfx and Vaz, along with a fair amount of delay, reverb, and distortion plugins. The vocals were recorded with a large-diaphragm microphone. The metal percussion sounds are older; I sampled and processed them on a hardware sampler back then.
