Algorithm

When the main checking function has detected a note error, next state reception will call the sub-function mididetector_checknoteerror which implements the following algorithm:

 BEGIN



		 for (all detected errors since last check)




index_offset = index(lastFollowedNote) - index(previousFollowedNote)



				 if (index_offset == (number of detected errors since last check) + 1)



						 if (pitch(lastPlayedNote) == pitch(nextExpectedNote)




Error = type SKIP NOTE



						 else




Error = type WRONG NOTE



						 endif



				 else




Error = type ADDED NOTE



				 endif



		 end for



 END
