-/*********************************************************************************
-*
-*   MIDITONES_SCROLL
-*
-*  Decode a PLAYTUNES bytestream of notes as a time-ordered scroll, sort of like a
-*  piano roll with non-uniform time. This is a command-line program with no GUI.
-*
-*
-*  There are two primary uses:
-*
-*  (1) To debug programming errors that cause some MIDI scripts to sound strange.
-*
-*  (2) To create a C-program array initialized with the bytestream, but annotated
-*      with the original notes. This is semantically the same as the normal output
-*      of MIDITONES, but is easier to edit manually. The downside is that the C
-*      source code file is much larger.
-*
-*  In both cases it reads a .bin file that was created from a .mid file by MIDITONES
-*  using the -b option.
-*
-*  For option (1), just invoke the program with the base filename. The output is to the
-*  console, which can be directed to a file using the usual >file redirection.
-*  Starting with the original midi file "song.mid", say this:
-*     miditones -b song
-*     miditones_scroll song >song.txt
-*  and then "song.txt" will contain the piano roll.
-*
-*  For option (2), use the -c option to create a <basefile>.c file.
-*  Starting with the original midi file:"song,mid", say this:
-*      miditones -b song
-*      miditones_scroll -c song
-*  and then the file "song.c" will contain the PLAYTUNE bytestream code.
