Thanks Fred
I guess there is no way to edit an MFD file and be able to change things like the Style, Name, Tempo and what voices are used .. I see that some of the data in each entry is coded in the actual .MFD file in Fake Book MFD's but they also contain an XLS file in normal text .. wonder what language they are using to create the final MFD file. Being a programmer I'm always curious.
