      Description



      Name: ddT132432 Date: 09/17/2001


      C:\>java -version
      java version "1.3.1"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
      Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

      This problem is reproducable in Windows 2000 and Me. My configurations :
      Win 2000 : Dell Inspiron 8000 laptop
      Win Me : Hp Pavillion. We have two of these machines, both exhibit the
      problem.
      Mac G4 running OS10.0.4, the MIDI file appears to playback correctly.

      You may find the following file useful :
      ftp://ftp.mgtsciences.com/pub/users/sun/Invention.mid

      Load this file into Windows Media Player and play it. This is the correct way
      to playback this file. Load it into Juke and play it. You will notice that
      the timing "walks" around. You may need to play them back and forth a couple
      of times to let your ear tune in to the difference.

      Groove is less pronounced due to the nature of what's being played. The problem
      is exposed in "Groove" at the point in time when the playback loops. There is
      a slight, but noticable timing error. Perhaps someone who isn't a musician
      wouldn't notice it.

        To expose the problem in "Groove" :
      1. Start Groove
      2. Click "loop"
      3. Listen closely at the end of the pattern when it loops.

      I am writing a music transcription application in Java. We are about to go to
      Beta sites, and this could be a major show stopper.
