Fun fact 1: The drums are mostly DPCM + Noise and I tried to keep each sound distinct and consistent, espeically later on during the chorus. I also had to make the DPCM sounds a lot shorter than they originally were when I converted them because the entire song had a low hiss over it.
Fun Fact 2: Square 1 does nothing this entire track except play the same square wave drum pattern. It fills in the gaps when the DPCM has to play a snare. Without it, the gaps are much more noticeable.
