6.  CSSYNTH.INF entry values
--------------------------------------------------------------------------------
    The following INF entries can be customized :

    -   Setting the Default CrsytalWave volume (GlobalGain)

        GlobalGain is a log scaled value, set on the cssynth.exe panel.  The 
        range of values is from 0 to 3ffh and the default value is 2f0h

        The INF entry is the following:    
        HKLM,Software\Crystal\CrystalWave\0.0,GlobalGain,1,f0,02,00,00

        Example
        To set the default volume value to 320h, the entry needs to be modified
        to read:
        HKLM,Software\Crystal\CrystalWave\0.0,GlobalGain,1,20,03,00,00


    -   Setting the primary DirectSound buffer size (DS_BuffSz_fSec)
        The default value is 1.00 second.  The INF entry is the following:
        HKLM,Software\Crystal\CrystalWave\0.0,DS_BuffSz_fSec,,1.000

        Example
        To set the buffer size to 1/2 second, modify the entry to read:
        HKLM,Software\Crystal\CrystalWave\0.0,DS_BuffSz_fSec,,0.500

        NOTE: The recommended size is 1.00 second.  Make sure the decimal point
              is included in the value since the data type is a floating 
              point.


    -   Changing the Window Caption (WindowCaption)
        The default value is "CrystalWave Synthesizer 2.30".  You may modify
