JFugue - Java API for Music Programming

Download JFugue

JFugue 4.0+ requires Java 1.5.0 at a minimum. A lot of Java Sound bugs were fixed in Java 1.5, and JFugue takes advantage of those fixes. JFugue 4.0+ also makes use of generics, varargs, and other 1.5 language enhancements. JFugue 2.1 still works with Java 1.3 and 1.4, and is provided below.

Important: The Tempo command has changed as of JFugue 4.0. It now represents beats per minute (BPM) instead of microseconds per beat, or pulses per quarter (PPQ). BPM = 60,000,000 / PPQ

Version Information

JFugue 4.0.2 - Bug fix release. May 15, 2008

  • Changes to StreamingPlayer: now there are two methods, stream() and streamAndWait()
    • stream() should take only a String or Pattern containing a single token, and will return immediately. You'll need to manually throttle the music you send.
    • streamAndWait() can take a String or Pattern containing multiple tokens, and will take the time it needs to play each token
    • DurationPatternTransformer promoted from org.jfugue.extras to org.jfugue
    • The timing on streamAndWait() is still not 100% correct. Still looking into this. Suggestions welcome!
JFugue 4.0.1 - Bug fix release. May 11, 2008
  • Fix to Player(Sequence) and Player(Synthesizer) constructors, which weren't initializing the Player
  • Fix to the transform() method of PatternTransformer, which wasn't returning the correct Pattern
  • Re-introduced Player.allNotesOff() no-arg method
JFugue 4.0 - Major release. May 1, 2008
  • Changes to Tempo
    • Change: IMPORTANT - Tempo has changed. It now represents beats per minute (BPM) instead of microseconds per beat (or pulses per quarter, PPQ). BPM = 60,000,000 / PPQ
    • New: Constants defined for Tempo: T[Adagio], for example
    • New: public static final constants defined in Instrument, Note, Controller, and Tempo, to facilitate compile-time checking when creating object instances
  • Changes to Note parsing
    • New: Chord inversions
    • New: Triplets and other tuplets
    • New: Supports double-sharp (##) and double-flat (bb) notes
    • Change: Duration for 128th note is now "o" instead of "n"
  • Changes to the MusicStringParser and other Parsers/Renderers
    • Change: Improved MusicStringParser - quicker, and easier to understand and modify
    • New: JFugue Elements (Note, Tempo, etc) now have verification strings for verifying MusicString parsing
    • New: Support for MusicXML through the MusicXmlParser and MusicXmlRenderer
  • Changes to the Player
    • New: Pause, stop, fast-forward, or rewind a Player
    • New: Player can be created with pre-existing Synthesizer or Sequencer
    • Fix: Player now ends play when the music actually stops playing, as opposed to when it expects the player to be finished based on the millisecond length of the sequence
    • Fix: Exported MIDI now plays at the correct tempo
    • Fix: Multiple improvements to StreamingPlayer. New stream() method for sending new bits of music, instead of adding music to a pattern.
  • Changes to Pattern and PatternTransformer
    • New: Pattern now has user-definable properties, such as Author, Date, etc. These are persisted to/from a saved Pattern file
    • Change: PatternTransformer's 'returnPattern' now accessed through getReturnPattern() method
    • Change: PatternTransformer no longer has getName(), getDescription(), getParameter() methods
    • Change: PatternFactory and RockPatternFactory have been removed. Rhythm takes its place
  • Updates to Special Features
    • New: IntervalNotation class lets you specify a piece of music based on intervals
    • New: Rhythm class can now control voices (in addition to percussion layers)
    • Change: MicrotoneHelper changes: It's now called MicrotoneNotation, and the notation has changed from [note] to <note>
  • Experimental MusicalEffects class for ornamentation
JFugue 3.2
  • Ability to generate music at runtime using StreamingPlayer
  • Improvements for Anticipator class
  • New EasyAnticipatorListener class
