 classical sounds in the MMSyn7.Syllable module and respectively in the MMSyn7s and Main modules. Changed the behaviour for "-s2" first command line argument
 for mmsyn7s executable. Some minor documentation improvements.
 
-## 0.6.4.0 -- 2020-03-01
+## 0.6.5.0 -- 2020-03-01
 
 * Sixth version revised E. Improved the performance of the 'main7s' function for the "-s" first command line parameter.
