Chord progression is generated by knowledge base. ACS uses two type of knowledge base. One is for theme part. Other is for bridge and verse.



(1) [Knowledge Base for theme] button Specifies a knowledge base file for creating a chord progression of theme part. Opens [ Open File] dialog box.
Knowledge base file is a text file that contains set of provability between two chords.
For example, "300:C M7 -> G7" means motion from CM7 to G7 occurred with provability value 300. If provability value is large, it occurs often.
The order of lines in the Knowledge base does not affect the result. Only number of provability value affects how often it occurs.
