  Dynamic Difficulty Creator
  I am pleased to share with you the "Dynamic Difficulty Creator" which :
  - uses the XML files of each arrangement to produce a new version of these files (files like "PART REAL_GUITAR.xml")
  - generates all phrases automatically (if not already created in EOF)
  - generates all levels of dynamic difficulties from 0 to 19 if needed for each phrase
 

DDC v3.7 supports various time signatures :  
- if a time signature is missing, you can now configure its categorization maps  
- the synchronization process in EOF must respect the rhythm (the measures, beats and time signatures have to be correctly defined in EOF)    
For best results :  
- during the synchronization process in EOF, do not move the notes, just move the main measures (vertical bars)  
- create sections and phrases in EOF carefully because they strongly influence DDC process  
- All sections and phrases must start on the main beat of a measure   
If these rules are bypassed, DDC can work, but the results are not garenteed ...

 
  I'm writting a dedicated tutorial about DDC : DDC Tutorial
