The Adoom port is not a bad one..it's good
and the sound works like Varthalll said if you download the midi instruments....
but...
the sound on Adoom port is not good cause none of the midi instruments sounds like in the original game
in other words:the midi sound on Adoom is very bad
as keropi said and I said ...the best way to go today to play doom is Doomsday port
bye
