   Object

  Included Modules

   Enumerable

  Class Methods

   decode(str)
   read(io)
   load(fn)
   new([format=1[, division=96[,tc=nil]]])

   The three methods decode(), read() and load() replace NoteOn with
   NoteOff when its velocity is zero.

  Accessors

   format
   division
   tc

  Methods

   This nearly have all methods of array object. In addition, this also
   have the following methods.

   ntrks
   self >> tr
   each{|tr| ...}
   join!
   encode
   write(io)
   save(fn)

   The iterator each{} ignores all nil elements.

  Methods

   This nearly have all methods of array object. In addition, this also
   have the following methods.

   nevts
   self >> ev
   each{|ev| ...}

   The iterator each{} ignores all nil elements and sorts events
   (stable).
