Pibrac is a nice little town in the south of France near Toulouse.
It has a pipe organ from Puget built in 1863 (16 stops)

The initial reason for sampling the organ was to document the current status of the instrument.
However as the quality of the samples were appreciated by several organists, it was decided to release an HW1 version of this organ.
The sample set is sold by the non profit organization: "Les Amis de l'Orgue de Pibrac". The only benefit for the author is the pleasure to play the organ even when the real instrument is not available. The benefits (if any 
) will be used by the association to maintain and promote the organ.

Here are a few demos that should allow you to appreciate the instrument.
The first version is purposely very close to the real instrument, including a lot of the defaults. We will provide to the users, improved and extended version in the near future. These demos have no reverb added:
