Buckow-Rieger Organ from Komárom v.2
Komárom (Komárno, Komorn) is one of the most important town of Hungarian historic. 

In Roman times it was a major frontier town (Brigetio).  Komárom was a significant role in the Hungarian War of Independence (1848-49) and it was built the biggest battle system in the Austro-Hungarian Empire. In 1918 - under the Treaty of Trianon - the city attached to Czehoslovakia. The city is currently in Slovakia, although the population of almost 65% of Hungarian mother tongue. The population is 37,000

The predecessor of Andrew Holy Church was built between 1674-77. The church ruined in the big earthquake of Komárom in 1763. The church was rebuilt in Baroque style in 1768-71. The Holy Andrew church is the largest church of Komárom.

The oirgan of church was built by Carl Friedrich Ferdinand Buckow between 1860-64. The Prussian Buckow was born in 1801 in Danzig. He studied with masters Schinkel and Grünberg and studied German and English and French organ building. His workshop was in Vienna and he built 54 organ. The organ of Andrew church was the largest and most recent work of Buckow.  Buckow died two weeks before the transfer of the organ.  The romantic organ with 42 stops was one of the largest organ in Hungary. In that time there was no such organ in Buda or Pest nor in Pozsony (Bratislava). In 1899 the Rieger brothers expanded to nine registers and partially rebuilt the organ. Since then, no changes have been made. This is both gratifying because the organ is preserved in its original state, on the other hand it is sad, because the organ is a state of disrepair. 


Recorded in summer 2015. I used six Oktava MK012 microphones, but only made the sample from the 2-channel front. The sample set is ready for Christmas 2015. I was not completely satisfied with the quality of the sample and always planned a new recording with better microphones. Unfortunately this did not happen because the condition of the organ continued to deteriorate. But in recent years I have learned a lot and my sample-making technique has improved a lot. So I decided to make a six channel surround version using the original recording. V2 is ready for spring 2020 and I think it is much better than v1. I am very pleased with this because I believe that this wonderful and unique organ deserves the attention of the world


The following friends helped me to make and publish the sample set (in alphabetical order): Dominique Dantand, Gábor Forró, Andrew Lecky, Gérard Lefranc, Alfred Morse, William Morrong, István Nagy, Andor Pecze, 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 48kHz/24bit, stereo, multiple loops (1-8) and multiple releases (3 levels). Equal, a=440 Hz

The sample sets are made in several forms.

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 near or far stereo modes or 4 channel surround mode too).

The Trial Versions of the Buckow-Rieger Organ from Komarom has a limited compass of C2-C3 (048-c to 060-c) in the pedal, C2-G5 (048-c to 079-g) in the manuals. All other functions work. 

If you are using the old (v1) version, you will need to uninstall it.
Install pack01 first. You can then use the stereo 'far'. Then install the 02 pack. After that, you can use the stereo 'near'. Finally, install pack 03. You can then use the surround version.

The order of installation is very important and the steps are not interchangeable.

Al Morse at my request made a patch for the Buckow-Rieger v2 sample. The patch affects the middle and short releases and helps with fast and staccato organ playing. My testers really like the Al Morse version, but this fix will change the sound of the organ a little bit.

Here are four video-demos demos so you can hear the difference between the two versions (playing Jean-Pierre Silvestre).

You can download the Al Morse patch and you need to install this file fourth.

After installation, you can use my demo versions or improved versions of Al Morse. You can choose between versions when loading Organ. The name of Al Morse's versions include 'AM'. You can switch between versions at any time, only the first load after the switch should be done with the 'Load organ adjusting rank ...' option. If you purchase the sample set, it will also include the original and Al Morse versions.

Guide: simple stereo from surround, how to?  

If you purchase the sample, do not uninstall the demo version, as this is also required for the full sample to work.
