About the Organ:
The organ of the St. Bonifatius church in Ditfurt/Germany has been built by Ernst Röver in 1903. Röver was one of the foremost organ builders in the eastern parts of Germany of the late romantic area. More than 60 of his organs are still in existance in this area of the contry.
Rövers organs are characterized by a large number of foundation stops of different tonal colors, mixtures without breaks and a sparing use of reeds. For this organ this means that about 2/3 of all stops are 16' and 8' stops providing the organist with a huge pallette of sounds. Both mixtures are straight without breaks, and the organ uses only two reeds, the Hauptwerk trumpet and the powerful Pedal Posaune.
His organs are also known for exceptionally high quality, he used the best materials available and put much emphasis on good craftsmanship, making his organs work flawlessly for very long. Röver brought the pneumatic unit chest to a level of perfection that yielded a response without noticable lag, making this pneumatic action organ respond as directly as a good tracker action. The action is also operating very quietly, and, since most of the sensitive parts are protected inside the wind chest, it is working nearly maintenance free for decades.
The organ has survived all modernization trends, maintaining its tonal characteristics basically unchanged. In 2006 it was restored to perfect working condition and some pipework that had been replaced by lower quality material during the wars of the past century could be replaced with new pipes made of the original material.
This organ is now a premier example of the late romantic period and of the solid craftsmanship of Ernst Röver.

This page will be filled with more information shortly. Meanwhile have a look at the booklet accompanying the sampleset. You can download it from here.
This sample set requires a powerful Windows-PC or Apple Mac-OS computer with 64-bit operating system and the Hauptwerk™ software Basic or Advanced Edition1 (version 4.0 or higher). A powerful CPU (e.g. a modern quadcore CPU) and sufficient main memory (RAM) are essential. The memory requirements for the Hauptwerk process with the sample set loaded are specified in the table below for the most important sample loading options.
A Windows-PC will need about 1 GB additional memory for the operating system and other necessary processes, a Mac-OS computer should have about 30% additional memory available due to its different memory management system.
The compression used by Hauptwerk when loading samples is lossfree, i.e. loading samples compressed does not result in any loss of quality. It results however in an increase in CPU load of about 15% during playing. The best quality is obtained when loading the samples in 24-bit resolution, loading in 16-bit will cause a small but noticeable loss of quality. Since these options can be selected for each stop separately it is possible to individually adjust the options to match the available RAM.
Additional options are e.g. loading with 20-bit resolution (about 10% less memory required than 24-bit) or to only load the first loop of each sample (also about 10% reduced memory requirement).
Approximately 8 GB of free space is needed on the harddisc to install the sample set.
1 The Hauptwerk Basic Edition will only allow you to load the set in 16bit resolution. For best results the Advanced Edition of Hauptwerk is required.
