MIDI file writing

The simplest code for MIDI file writing is:

file.Write("Some great song.mid");

If a file with this name already exists, you'll get an exception. To overwrite existing file pass true to overwriteFile parameter:

file.Write("Some great song.mid", overwriteFile: true);

Compression

You can set specific policies via WritingSettings to reduce the size of an output file. For example, to use running status and thus don't write status bytes of channel events of the same type, set properties shown in the following code:

file.Write("Some great song.mid", settings: new WritingSettings
{
    UseRunningStatus = true,
    NoteOffAsSilentNoteOn = true
});

Complete list of available properties is placed in the documentation of WritingSettings.
