Class DurationPatternTransformer

java.lang.Object
  org.jfugue.PatternTransformer
      org.jfugue.extras.DurationPatternTransformer

All Implemented Interfaces:

java.util.EventListener, ParserListener

public class DurationPatternTransformer
extends PatternTransformer

The DurationPatternTransformer multiplies the duration of all notes in the given Pattern by a factor passed as a parameter.

This transformer can be used to increase or decrease the duration of notes. To increase the duration, use a variable greater than 1.0. To decrease the duration, use a value less than 1.0. The default value for this transformer is 1.0, which will result in no change to your Pattern.

For general information on how Pattern Transformers work, refer to the JFugue documentation.
