The .SNG file format was supported up to the "Digital Orchestrator Pro"
    program (2002). Life has to move on, so this format is not supported
    anymore by the "Record Producer" series. 

    Here is a two step workaround to use SNG files with RP_DLX. This also 
    requires that you have "Digital Orchestrator Pro": 
    
    *  Use DoPro to open all your .SNG files and save them as .ORC. 

    *  Then you can Open them in RP DLX. RP DLX is compatible with the 
       previous ORC format but not with the over 12 years old SNG format.

                              ***   
    NOTE:
       We understand that a lot of SPG users have created libraries over the
       years (some with thousands of SNG files) that they need to use in newer
       systems. These users had a good chance to purchase the discounted
       Upgrades that we offered for almost a decade. Unfortunately, at this 
       time "Digital Orchestrator Pro" is a Discontinued product that is no 
       longer available.
