Turok: Dinosaur Hunter - Jungle (Prototype OST)

An early rendition of the music heard in the jungle level of Turok: Dinosaur Hunter. It's mostly the same but uses different instrument samples particularly towards the end.
The track title of the MIDI is "Jungle PSX". It seems each midi that had the notes pitch adjusted for the N64 end in "U64" while the ones that didn't end in "PSX". Could be evidence of a potential PS1 port that never materialized, but to my knowledge the game was always developed as a N64 game so maybe it means something else.
