The Gottfried Silbermann organ in Großhartmannsdorf has two manuals and pedal with 21 stops. It comprises 1178 sounding pipes, the prospect is completed by 26 silent pipes. The organ case is 5,50 m tall and 4,30 m wide, the middle tower of the prospect shows the emblem of the church patron, who signed the contract with Silbermann and paid a substantial part of the cost of the instrument. The organ was inaugurated on the 3rd December 1741.
This instrument is one of the best preserved organs of Gottfried Silbermann, it has been well maintained but never been modified significantly. First repairs had been carried out by Adam Gottfried Oehme from Freiberg in 1780, further works by Gebr. Jehmlich from Dresden. Since 1952 the organ is maintained by Eule Orgelbau from Bautzen. It is not known at what time the temperament of the organ has been changed. It is now tuned to equal temperament, but still nearly a full note higher than todays concert pitch. Analysis of the samples shows a tuning with a1=462 Hz.
Many recordings are available with this instrument, mostly with works by J.S. Bach. The organ has a very bright and clear sound, which is typical for the instruments of Gottfried Silbermann.

The Sample Set
The organ has been recorded with high quality microfones and preamps in 16bit 44100Hz sample file format. The samples have been carefully denoised and prepared for use with Hauptwerk. Our own SampleLooper software has been used to compute loop points (up to nine/sample) and help setting the release markers. The original recordings have a lenght of 30 seonds/note for the manuals and 60 seconds/note for the pedal. These have been shortened to 8 seconds/note and 15 seconds/note resp.. The samples contan the original room reverbaration, which is about 1.5-2 seconds. As in our other sample sets we have created artificial staccato and portato release layers using convolution. The impulse response used in this process has been carefully designed to match the original reverb. If you do not want to use these artificial release layers, you can select to only use the default release sample in the rank audio output routing screen in Hauptwerk. Advanced Features:
- The compass is extended up to g”’ in the manuals and f’ in the pedal. There is a switch to toggle between extended and original compass. This is mainly because some of the stops are repeating, and for the extended compass they break at c”’.
- The tremulant can be switched to work as in the original, effecting the entire organ, and to only effect the OW, which makes it much more useful.
- The organ is tuned to a pitch of a1=460 Hz. A switch is provided to easily switch this to the standard pitch of a1=440Hz, without loading a different temperament file or using the HW tuning feature.
- There are two settings for the wind model. One is as unstable as the original, the other is more stable. Naturally you can also adjust using the organ settings menu. (Unfortunately only non US customers can benefit from that).
- Eight general combinations have been added to the GUI to allow rapid registration changes
