keys:

    
  
    
    
    
    
      p                      
      pause/continue
      s
      toggle autoscale
    
    
    
      ] or c
      go to next measure
      l
      toggle line/measure cursor
    
    
    
      [ or x
      go to previous measure
      h
      toggle help
        In addition, when
synchronization is enabled:

    
  
    
    
    
    
      ,
      shorten the duration of the current measure
      ctrl-,
      shorten the initial offset (idle time before cursor starts
      moving).
    
    
    
      .
      lengthen the duration of the current measure
      ctrl-.
      lengthen the initial offset.
    
    
    
      w or
    save button    		
      save timings, abc code and other settings to a file.
        When abcweb                is opened with the name of this file as
        parameter in the url, it preloads the score and media. Example:
              http://your.domain.org/abcweb.html?file_name. Also works locally
        with file:///path/to/abcweb.html?file_name
        
    (Note: you have to correct the path to the media file in the
        saved preload file).                 

synchronizing:

    
  
  • When your audio file is synthesized from score, no manual synchronization
  is necessary (but, see requirements below).            Otherwise (e.g. live
  performance or video) you have to synchronize the media manually.
    • 
  
  • By clicking in a measure you synchronize the *first* beat of that measure
  to the audio.            After clicking, playback jumps one measure backwards
  for auditing how well the entry of the measure became synchronized.
  You could then click again to improve synchronization.
    • 
  
  • Clicking in the first measure synchronizes the first beat (of the music)
  to (the first note) in the media file. This            sets the, so called,
  offset of the media file.            Do not forget to look at the measure
  duration and offset numbers in the top right hand corner of the display.
       You can also adjust these numbers (more precisely) using the keyboard
  (e.g. while the music is paused).
        abc requirements for
automatically synchronized score (e.g. using abc2midi):

    
  
  • metre definitions should be in the form M:x/y (a single quotient).
    • 
  
  • tempo definitions should be in the form Q:1/y=... (beats per minute).
    • 
  
  • tempo definitions should occur at the beginning of a measure. (if not,
  they are still treated as if they did)
    • 
  
  • the media should be .mp3, .ogg or .mp4, webm
