Aeris Castilian replica Organ from Budapest                           
Gazdagrét is a neighbourhood of Budapest, the capital of Hungary. It is located in the western part of the 11th district. It is a residential area consisting of prefabricated buildings (see panelház) with a population of 11,929.  

This housing estate was built in communism and it was forbidden to build a church here for decades. The foundation stone of the Holy Angels church was built in 1990, but it was built only very slowly,. It was dedicated 25 years later, in 2016. The church is one of the most beautiful modern Hungarian architectural works, its interior is wonderful. The mosaics decorating the walls of the sanctuary were made by Marko Ivan Rupnik, a world famous Slovenian Jesuit artist. The crossroads are the work of Barza Buza  

The organ was produced by the Aeris organ factory in 2016. The main profile of this organ factory is the restoration of old organs and the creation of a certified copy of historical baroque organs. One of the most successful pieces of this work is this little Castilian organ. The organ of the Santa Maria church in Tordesillas (by Phelipe Urarte, 1716) served as a model for this instrument. The reed-pipes of organ made by Joaquín Lois, a famous Spanish organ builder  


The following friends helped me to make and publish the sample set (in alphabetical order)Dominique Dantand, Gérard Lefranc, Jean-Pierre Silvestre and Adrian Wheal. If something's done well, it's thanks to them.  Thank you for their work  

Sample quality 
The sample sets are available in wave format 48 kHz/24 bit, stereo, multiple loops (1-14) and multiple releases (2 levels). 

Equal, a=440 Hz or a=415 Hz, enclosed with the original ¼ comma meantoned temperature.             

The sample was made in two separate versions (original and extended).

Each version can be used in three formats:             
a.b. Two channels stereo of wet and semidry
c.    Surround version (3 pairs of stereo recording: close (near); at distance (far) and in the background (rear).

In the surround version you can adjust the perspective by setting the volume of the near, far and rear recordings. (Suitable HW loading and channel settings can be used to give wet or semidry stereo modes or 4 channel surround mode too).

The sample set reverb is 2-2.5 s reflecting the original acoustics of the church.  

Hauptwerk v4.2 or v5 supported for the Organ Definition Files.

Demo Installation instructions: 

Install the part01 of the stereo-wet version. Install the part01 and then the part02 of the semidry version. Install all three packs of surround version. It is important to sort.  

Surround vs Stereo mode

If you do not have a surround sound system, but there is enough memory (RAM), I suggest you also install the surround version. If you activate the front and rear stops too, then you will get a more compact and fuller sound than the simple stereo.
