MIDI is the name for the protocol, see MIDI specification.
There's also the MIDI file format (which has the time information). Then there's another format for which I couldn't find an official spec:

You should be able to see pattern in MIDI files if they are not compressed or encrypted. Do not focus on single file. Some pattern are not that ovious. See also:

Can you please also provide information for the size of the files, e.g. how big is each KYD?

Songs are already represented by each file with the file extension KYD. (older mode Vivaus Pro ha KYC file extension, not sure if it the same format).
I can't really tell if the file is already close to a Midi file or if there were encryption, since I am not familiar with the .MID format. I tried renaming it to .MID and .KAR already, but can't be played. So, a conversion is necessary.

In the \RSONG folder, it has the following files:
  - EVENT.DAT - looks like it contains the list of new songs (referenced to other file) in the past 12 months
  - HIST.LST  - just a text file, listing the previous 12 months date
  - MEDSUB.DAT - no idea yet
  - SINGER.DAT - list of all the singer terminated by NULL character. They may be indexing in the file to the the singer name
  - SORT.DAT - most likely for indexing purposes
  - TITLE.DAT - List of all the titles of the song, it contains a header and additional DWORD value right after the song title
  - TITLE.INX - well, most likely the index for the titles (no idea yet)

If I can upload the song files directly, they I can save some bucks. The song files (.KYD) are just additional files while the 7 files I have listed above will be replaced/overwritten. So, not knowing the fileformat of those file is still okay for now. I will need to test this first on the next song update they will provide.
