Doom - E1M1 on eight floppy drives

Support me on Patreon! - I actually hit the limit of my Arduino with this song. I had intended to have the other seven drives play the really fast parts as well, but the Arduino had trouble switching pin states for all the pins necessary so fast. So instead I just got like five notes out of something thats supposed to play thirty. I don’t think it was because it couldn’t switch pin states fast enough because I improved the number of cycles it takes to do that, but rather because the loop used to do so isn’t effecient enough to keep up with that many operations.
