Class IntervalPatternTransformer

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

All Implemented Interfaces:

java.util.EventListener, ParserListener

public class IntervalPatternTransformer
extends PatternTransformer

The IntervalPatternTransformer alters music by changing the interval, or step, for each note in the given Pattern. For example, a C5 (note 60) raised 3 steps would turn into a D#5 (note 63). The interval is passed in as a parameter.

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