some years ago, i used to modify midis to use them in my proyects, some turned up good, most of them not, i dont know if anybody will find them usefull for their own proyects but anyway, hope you people enjoy them.
Spoiler:
D_VICTOL - attempt to make the original midi sound kindda like darkness dawning from the album the dark side of phobos... and it seems it failed
TENSEMAP03 - i wanted to make the song more tense, and i think i succeded... by the wrong reasons
SMAP07 - Map07 + Slayer's original song, not very good, but not bad either
DMRe2m8 - My first doom proyect ever was called doom reincarnated, years latter i wanted to remake it and for one of the levels i modified the e2m8 mid, and i think the result was very good
E2M4B - Did it as a request for a friend... meh, i never liked the original song anyway
