All right folks, THIS IS IT! Perhaps my most ambitious build!

Taking Inspiration from Les Deutsch, Al Morse, Tim25, Organist117 and others, I have built my own Friesach Extension!

I have the latest version of GrandOrgue and the sampleset begins to open but then gets stuck and ultimately just closes the entire program

My best guess would be a system problem? I believe this requires at least a 16GB RAM PC to run this. Perhaps you've encountered a hardware limit?

Hi! i did the steps but i got an error that says: "Out of range value at section 'Rank088' entry 'Pipe068PitchTuning': 1300.262140" and then the sample doesnt open.

This is a classic error of not running the latest version of GrandOrgue. Please download the latest version which I believe is 3.17. The earlier versions did not accept beyond 1200 PitchTuning code.

Instructions I wrote for another user struggling with this:

Step 1: Download the Friesach organ from Piotr Grabowski - I believe he lets you choose GrandOrgue OR Hauptwerk. Choose GrandOrgue. Extract the .rar file with a .rar extractor such as WinRAR to ANY directory - I usually use a directory called "OrganInstallationPackages" which is what most of the organs require as the parent directory.

Step 2: Make sure the .organ file - in the case of Friesach from Piotr Grabowski it is called Friesach.organ Or Friesach FullImageResolution.organ is inside the same Parent directory as the "Data - Friesach" directory.

Does this make sense so far?

In other words - so far you have the "Data - Friesach" Directory and your Friesach.organ file INSIDE the same parent directory

Step 3: Double Click on the .organ file

This will start GrandOrgue if you have the current version installed. The current version is 3.15.4 I believe.

For My Extension - I have made it very simple.

Step 1: Download my .rar file from mps-orgelseite.de

Step 2: Extract the contents and place the Friesach6Manual.organ file and the "go-odf" directory INSIDE the same parent directory as the other two things mentioned above. That is, the Friesach6Manual.organ and go-odf directory are together with the Data-Friesach directory and the Friesach.organ file.

Step 3: Run the Friesach6Manual.organ by double clicking it - this should launch the GrandOrgue software and the 6 manual organ that I constructed from the Friesach stops.

If this doesn't work email me at pianoorganpraise@gmail.com

The heavenly voice never has the first 12 pipes. It always starts from the second C!

It depends what the organ builders decided to do! Most organ builders want to save pipes by not starting the celeste deep down-it is useless anyway until about C13. I have seen some unda maris' start at G20.

When I make my own celestes and unda maris' (using beating tuning) I create them from Pipe001 - easier to do this. I have not found any downside to this especially as the organist does not include this stop when playing loudly.

And..the Nancy organ that I am working with now appears to have a beating effect celeste that starts from Pipe001.

Take Care!

I follow your work and I really appreciate your organs.
however, I don't think it's as you say... (or maybe it's the fault of google translation)
all the celeste stops don't have the first 12 notes, because over the centuries it has been understood that, simply, those pipes sound bad. of course I have also seen organs with celeste stops starting from the second G, and this depends on the type of pipes used for that particular stop.
Personally I have nothing against experiments,
but an Unda maris 8' is born from a second row of pipes, tuned sharp, of Dulciana 8'; not Salicionale, not Viola da gamba.
In the same way the Fiffaro or Voce Umana is a second row of Principale 8' stops, not Prestant or Diapason.
Thus the Voce Celeste 8' that the French demand robust on Gamba pipes and the Germans prefer very sweet on Salicionale pipes, tuned flat or sharp with a very penetrating effect and soft and vaporous sounds.
in all these cases we will never find the first 12 pipes in the beathing row, indeed, in some mechanical organs these rows begin from C25!

Dear Simmy,

Thank you, you appear to be very knowledgeable about these stops. From my studying, it was my understanding that the Unda Maris was always tuned flat and did not beat at the same rate as the Celeste does - I believe a slower beating for the Unda Maris - but I would have to look that up again. For me, when I am making virtual stops I have to use what is available - I do not care whether I am making a Celeste or Unda Maris from a Prestant, Salicionale, Gambe or Dulciana because I am not a purist. If I was a purist, I most certainly would not be playing these extended demo and composite builds that I am making! As long it sounds lush and lovely, I am not bothered about this.

I was just glad to discover how to tune a uniformily beating celeste using the Logarithmic formula of c = 1200 × 3.322038403 log10 (f2 / f1). For example an A440 can be tuned to a cent difference of 2 beats per second by using A440 as F2 and A442 or A438 as F1. This can be done for every pitch of the entire frequency range of the keyboard.

Did you check out the Nancy Cavaille-Coll Organ - it has a full range Celeste! From the sound of it, it is not perhaps beating terribly far off from the unison stop so that the rumbling effect is not too bad at the bottom.

Looks like the Viola Celeste is playing at 4' and not 8'

I have tried. It sounds very compact, better than composite sets.

Thanks for sharing!
