Oh no...the numbers are quite quite important.
We've replaced the entire music.tbl file in Babylon Project, and while im not a idiot on howto edit table files (ie. im not breaking the parser) I am 99% sure now that the numbers are causing a consistantly happening Illegal Operation apon closing FS2 when using the music.tbl file for The Babylon Project.
The information on Dnet was useless as it talks about measures and you don't determine that by looking at file formats as the information implies. And yes, I am a musician and I have been playing music for the better part of 7 years. No, im no music theory genius and I definately do not have a great level of musical notation understanding, but the number of measures doesn't help me here.
