some side notes:
I have asked Bob and Barn (via Facebook) about the MediEvil soundtracks, and they shared some interesting info: the main sample libraries used are “Sound Ideas - Symphonic Adventures” and the Peter Siedlaczek ones (such as Advanced Orchestra). All the other sounds come from a Roland JV1080 and a Kurzweil K2500.
other stuff I found out:
- the skeleton laugh from MediEvil's main menu also appears here
