This is a longshot, but I guess it's worth a try.

I still use the ancient version of Buzz from circa 2000.

WAY back in 2007, I had composed a track, and sure enough -- it got corrupted during the save process, and now it opens to just a blank view from old-school Buzz. (You basically see the MASTER generator, and that's all.)

I noticed today that the content of the track is still largely there - I had opened it up with a hex editor, and you can clearly see all the generators and effects in there.

Theoretically, are there any utilities that exist that would take a BMX file and restore its file structure so it can load?

My Plan B was to try and get a better understanding of the BMX file format to see if I can go in and manually repair the data with the aforementioned hex editor.

Thanks! That looks like it would definitely fit the bill. I'll let you know if it works.

[EDIT : Nah - I think it's a lost cause. After trying to both open it and rescue it, I got errors. Reviewing the file format further, it looks like most of the machine info is intact, but the file clearly got cut off prematurely, removing most of the pattern info. I can still probably use the info I can retrieve with the hex editor to try and recreate something like the original file, anyway.]

You may already know this, but the newer Buzz versions save a .backup file specifically in order to prevent this from ever happening.

Yeah - I really, really should upgrade, but I'm a creature of habit.

I may give the new version a try, but I doubt ever I'll quit my grunge-era Buzz addiction completely.

I have this little utility called paramfix. If I remember well, it was an utility to fix some wrong bmx.
I think it was working with drag'n'drop the bmx or bmw on the paramfix.exe.
Maybe you can make (always) a copy of the bmx and try to drop it on the exe and see if it helps ?

Is there someone here remember what was the exact purpose of paramfix.exe ?

Anyway, hope that helps :D But dont expect miracles... :|

EDIT : I was right, here is a description found on a site :

not a machine. small exe that can fix a certain type of broken bmx by renaming the PARA section to LJUD>>>. zephod >>> wrote the exact same thing but thought up a less funky name for it.

found it on USR site :

EDIT 02 : Do you run Buzz as Administrator ? (right-click on the exe and use "Run as Adminitrator"
