3 GB limitations of current Windows

Because I was asked by several users about the subsets available, I summarize here the main point:

The Litomysl sample set is quite a big organ and the loops of the samples are long (several seconds) to ensure rich and realistic sound. Therefore, the memory requirements are ENORMOUS.

However, the current versions of Windows systems have a limit of 3 GB per application (although you can have more physical memory istalled). That means, that you cannot load under any circumstances the completely whole set. We will have to wait for the future versions of Windows to be able to load it. A note: I could not try it so far, but maybe, if you have more physical RAM installed, you can run two instances of Hauptwerk - each with a different subset of Litomysl, forming together the very complete Litomysl organ.
Neverthless, I have made several subsets which are loadable by current versions of Windows (i.e. under 3 GB of RAM). As the organ literature does not usually count with enormous instruments, I am convinced that these limitations are no obstacle to perform any organ piece written so far.
The full set mentioned on the screenshot page is really full in terms of stops used: all available stops are loaded into memory. However, to follow the Windows limitations of 3 GB I have shortened the compass of manuals (4 octaves) so that the organ can be loaded at all. Therefore I call the subset "Full -shortened".

The complete compass of the instrument may be seen on the pictures of the real console. As far as I know there is no real instrument having full 5 octaves compass. It is not organ-like. It is just that digital world counts with 5 octaves, not the organ world. As far as I know, also the big instruments usually finish at high G or A. In case of Litomysl, the compass finishes at G, so it is 4.5 octaves.
The compass of organ pedals also vary considerably. In the baroque period, the pedal had just 18 tones, covering 1.5 octaves. Later, it has become usual to finish at D (2+ octaves), nowadays, the compass of the pedal is usually up to F or G (2.5 octaves). In the case of Litomysl, the compass is up to F (2.5 octaves).
I am pretty sure that this compass enables to perform any organ literature, because also the composers know the limitations of the real-world instruments! However, if a kind of digital "furia" comes to one's mind, he can, of course, extend the compass of the instrument using a third party tools, such as a freeware PipeTune from Martin Duemig. But my aim is to give the playable images of the real organs, I am not a fun of "digital organ school".
