Under the Covers – Notation

A few days ago John asked a great question over on our Facebook Page:

Could you tell me if it’s possible to copy some of the sheet music that’s on my Wersi OAX onto a USB stick, so I can transfer them onto my computer then use my music notation program to change some tunes into a key that I like to use. If so can you tell me how to copy the sheet music onto a USB stick?

After a little digging the short answer is No – 🙁 But, let me share what I do know and see if anyone else can add to that.

First – DON’T try this unless you are very comfortable with Windows and can restore your instrument should you click on the wrong thing by accident! – Did we mention USE AT YOUR OWN RISK?  Ok, now let’s have some fun!

The first question is where are the notation files stored? That one is pretty easy. You can find them in the directory C:\WERSI\Scores\Fact (there is also a directory called C:\WERSI\Scores\user where any notation files you upload are stored). You might notice two things? The name of the file (N0000_0) and the file extension of “dat.” Here are the first few files:

Volume in drive C has no label.
Volume Serial Number is 95A7-74C4

Directory of C:\WERSI\Scores\Fact

01/07/2017 12:10 PM <DIR> .
01/07/2017 12:10 PM <DIR> ..
12/12/2015 06:56 AM 52,559 N0000_0.dat
12/12/2015 07:08 AM 59,384 N0001_0.dat

That name doesn’t match up to anything we recognize unless you happen to have access to Microsoft Access or some utility that can open and read an Access Database. We copied the Access database from our Sonic to another PC where we have Access installed. There is a ton of very interesting data in there, but we are only going to show you info from the table called “Fact_TableScores_New”. Here’s what the first few lines look like (Click on it to make it big enough to read):

Access DB Notation
Access DB Notation


Look under the column titled “SongSheet” and notice the first two entries in this table match the first two files in the directory we listed out above. So, now we know that the file called N0000_0.dat is the notation for the tune called Verde – Ricky King. You can figure out the next one.

Now, comes the problem. We have no idea of what program is needed to properly open and display those files. We copied the first file and opened it up to find only one clue.











No idea that this is/isn’t file that you could open in Photoshop or not. We don’t own Photoshop and have never used it. We do know that *.dat is not the default extension used by Photoshop.

At this point, we will open up for comments from others. Anyone have thoughts on how to properly open the files so John can transfer and use on another device? It very well may be that Wersi does their own file encode and decode, but I suspect they are using some off the shelf utility rather than writing their own utility for that. I’ll also add that we have loaded a few of our own notation files. Those were originally in *.jpg format but are now saved on the organ in the mysterious *.dat format.

John – Suspect this isn’t the answer you were looking for, but we do have a group of smart folks following along. Perhaps someone will have some ideas for next steps.

    Hi Curt I have two music notation programs, the main one I use is called Encore 4.5
    and the other is called MusicScore 2. I thought of taken photos of the mWersi music files,
    but I thought of asking you and any Wesri members if they knew of a better way of copying
    the Wersi sheet music files. Thanks for the members suggestions.
    regards John

    Hey John, What notation program are you using? What file formats can it open? I’m guessing XML, MIDI and whatever native format it’s using?

    One other question – Which song(s) are you interested in?

    I use StarOffice, and found that USER files under under the Scores directory can be displayed using the Database of StarOffice, but FACT files cannot be displayed, so presumably they are encrypted somewhere and only moved into the Scores directory when activated.

    Take a picture with a smartphone and switch to a computer

    Hi Curt/John/Geoff,

    as mentioned in the the first line, the graphics format should be “PNG”.
    But I haven’t tried it.

    Maybe an easy work around…I didn’t try this myself…but, why not connect a keyboard and hit the “print screen” button? Then paste it in Paint and crop it and save it in JPG? Would that work? I don’t know, but I think it is easy enough to try?

    Hi Curt/John/Geoff,

    Coming at this from a different direction, when you view sheet music on the Sonic does OAX spawn another process/task or application. Might be worth checking in task manager to see if anything looks different when you view sheet music.

    Like above comment, I can’t believe that Wersi wrote their own encryption routines or indeed a sheet music viewer when there are plenty of public domain offerings out there – but maybe wrong.

    I used to work with the UNIX operating system which used .dat files. I wonder if a Linux installation on a PC would read the files? Otherwise I believe that under Windows, .dat is a general file extension for data files and you would need to know which utility was used to create the file.

    Thank you for trying Curt, it looks like a lot of in depth work needed, So I’m looking forward to any members coments before I tryto do it?
    Regards John
