Looking for the "voicing booklet" for the1824/1828 Lohman, St. Catharinakerk organ


Dear Friends,

I own the sample set produced by Sygsoft of the 1824/1828 Lohman, St. Catharinakerk, Heusden, organ located in The Netherlands. AFter I installed and loaded this organ, I immediately noticed that--despite having some marvelous stops--there is a lot of unevenness among its ranks. Some ranks are loud and piercing and others muted. Overall there is some lack of clarity.

I found this comment about the set on pcorgan.com:
"With Hauptwerk Advanced, missing 'clarity' can largely be solved with voicing.
John Boersma has written a clear story about this, see: John Boersma: Sample Set Lohman organ in Heusden. I applied for his free booklet, tried it on some registers and it really works: I got the voices clear!"

Unfortunately, John Boersma removed the link to his free booklet and seems to have torn up all his notes relating to Sygsoft sample sets. His only response to my email was that Sygsoft has never been able to produce a decent sample set and to look elsewhere!

That's all fine, but since I do already own the sample set for HW 4.2--and reselling it and re-licensing it to another user is now impossible--I would love to re-voice it and work out its rough edges. I believe this sample set can be vastly improved, but I need guidance!

Does anyone still possess an electronic copy of Boersma's booklet on revoicing this organ? I tried to get it from Gert of pcorgan.com but received no response to my inquiry. I would greatly appreciate help obtaining these instructions to use as a starting point. Or any other advice from someone familiar with this set.

Thanks very much in advance.

I want to add here that Fred de Jong of Sygsoft Holland himself replied to an inquiry I sent him by direct email. I have nothing but praise for Fred. Although he could not offer me the voicing booklet I have been looking for, he reassured me that the Lohman sample set has been their best seller for years. Listen to the audio demos posted on the Sygsoft website at https://www.hauptwerk.nl/mp3lohmanheusdenen.php and here on Contrabombarde and you will understand why. I fully agree with Fred that it is a very worthy set. I am confident that the irregularities I am finding should be manageable with the Hauptwerk voicing tools, as he suggested.

Since Jan has kindly offered me Boersma's booklet, I would be happy to pass it along to anyone else who might find themselves in this same situation and wants to take a look at it.

Why don't Sygsoft Holland do the revoicing and issue a corrected sample additional to the original if they feel that the original has qualities that should be preserved.
I also feel that there is some readjustment work that could be carried out to smooth over a few inconsistances in the Laurentius organ of Rotterdam. Eg The Vox Humana.
