MidiJingle

Midi jingle packet is used to play a short midi song, typically when the player accomplishes something. The normal song that was playing will be resumed after the jingle finishes playing. In the old days, the lengthInMillis property was used to tell the client how long the jingle lasts, so it knows when to resume the normal midi song. It has long since been removed, however - while the client expects a 24-bit integer for the length, it does not use this value in any way.
