I don't mind getting down to some hard core bare knuckles C++ or C# bit-level programming if necessary. Although it would be nice if the custom creation of realtracks were supported by BIAB (or RealBand) itself, I was thinking that if the format of the BT0 file were available I could write a custom GUI application to create appropriate BT0 files to match the WMA files containing the real audio. Do any members of the forum happen to know if PG Music is willing to provide information on the BT0 format and other technical information that might be neecessary to create such real tracks?
