However, we have designed a PC program which will convert .SNG files to .MID format. You can download a Windows version. Some users apparently have problems with the Windows version, which we believe is cause by some type of conflict with other files in their system, but have not been able to identify. If you have problems with the Windows version, you can download a DOS version, which seems to work for just about everyone.
