Hi,

This isn't a bug with PicoGUS but it's something you might want to add to your compatibility list wiki page (I don't have permission to edit it). Doom uses the DMX sound library which has a bug that causes it to play the wrong patches for some instruments. There's a PWAD I made that fixes the bug.

A demo video is here that shows the difference it makes. The same WAD should also work for other Doom engine games: Heretic, Hexen, Strife, Chex Quest.

Thank you so much for this, I was scratching my head at why Doom 2's first level sounded so comically strange. It does exhibit some silent instruments with E4M1's music but it sounds quite great
