MidiFileInfo

Getting information about a MIDI file

Purpose. Displays general information about a MIDI file: MIDI file type, division type, timing resolution, length (in ticks) and duration (in μs)
Usage. 

java MidiFileInfo [[ -f ] | [ -u ] | [ -s ]] [ -i ] [ midifile ]

Parameters. 

-s

use standard input as source for the MIDI file. If this option is given, midifile is not required.

-f

interpret midifile as filename. This is the default. If this option is given, midifile is required.

-u

interpret midifile as URL. If this option is given, midifile is required.

-i

display additional information

midifile

Bugs, limitations.  Some combination of options do not work. With Sun's implementation tick and microsecond length are only shown with option -i. With Tritonus, length and duration cannot be displayed at all.
