A room that is 15x15 is fairly generous when it comes to = residence organs these days. How many ranks do you have now and what are they? = Maybe a little trumpet will do the trick. Sometimes a few string ranks with couplers can provide a "massive" sound that has warmth.   Larry   > -----Original Message----- > From: Jon Calvo [SMTP:jcalvo@mail.state.tn.us] > Sent: Friday, July 27, 2001 3:44 PM > To: DIYAPASON-L@pipechat.org > Subject: RE: [Residence Organs] Pouch boards > > Larry > the organ is in a 15 x 15 room there is not a lot of room for the organ = to > properly sound like it should so if a 32 ft would create any odd > vibrations I may just chuck the idea of a 32 and go with maybe something > more controllable like a small electronic trumpet if I can find one that > would work , the main idea of the 32 or the trumpet is to give the organ > some bite , the organ is completely exposed and really needs some type = of > warmth or controllable sound to it , I hope I am making sense what is = your > opinion > > john C > > >>> larry.covington@St-Louis.org <mailto:larry.covington@St-Louis.org> > 07/27/01 02:40PM >>> > John, > > A lot depends on the scale of the 16' octave and the acoustics of the > room. > The larger the scale the more pronounced the 32' effect.

Unfortunately the unit is noisy and I had to locate it in another room. It certainly puts out the wind very well. I over rated mine on purpose in case of expansion.   I would caution anyone who uses one of these blowers about putting them inside a sound proof box. The motor must have good air circulation or it will cut out. This could be really inconvenient when your trying to play.   Steven Durham Portland, OR ----- Original Message ----- From: <DEMPAR1@aol.com> To: <DIYAPASON-L@pipechat.org> Sent: Monday, July 30, 2001 8:38 AM Subject: Re: [Residence Organs] small blower - details     Just wanted to throw this info out regarding the small blower discussion: WW Grainger sells a "welding fume exhauster" fan which has 3" standard ventpipe connections.

(back) Subject: [Residence Organs] Re: Buzzy Diapasons From: "Eric Sagmuller" <ess4@psu.edu> Date: Mon, 30 Jul 2001 12:34:14 -0400   Hello Friends,   Thanks for all the input. I think I'm going to have to find an expert to help me with these pipes. I was able to get one of the worse ones more acceptable by tapping the languid down slightly. But the most offending one in my 8' rank is actually a little worse now. It almost sounds a little like a kazoo. The other strange thing is that I can't get a couple of these offending pipes in tune. The collar is all the way down and they still are too flat. I don't know though if this is related, as the pipes were running a somewhat higher pressure on the organ they came from. This would have raised the pitch a little.   The closest organ builder I'm aware of that has the capability to do these adjustments, is located about 3 hrs. from here. Anyway, maybe I'll take a trip someday and watch some of this work being done.   Eric

And it is continuing with John Bishop as the Executive Director. Right after the OHS Convention, at which John was able to raise the money needed to save a Johnson organ up in Brooklyn, NY, he was heading directly to Brooklyn to remove it before the windows were taken out of the church it resided in. And from having a couple of breakfasts with him i know that they are going "great guns" and all of us will be seeing much more about them. Alan had been rather sick for several years so the OCH took a rather low profile for some time now.   I am also needed to contact John so I will try to give him a call in the next couple of days and will let him know about the problems with the domain name. It is not listed in the "root servers" currently which means that maybe somehow through the transition someone missed renewing it.

(back) Subject: Brummbass From: "Mike Gettelman" <mike3247@earthlink.net> Date: Mon, 30 Jul 2001 20:12:10 -0400   Hello I am a bit of a lurker on this list, but was motivated to tell you about what I learned were the facts about the Brummbass. I was somewhat amused to read the posts concerning the Brummbass, particularly those relating it to the Brumm sound of a Harley. I sent a post to my friend, Ken List, a Tonal Finisher at Schantz, describing the information suggested here, that the Brummbass originating as a Schantz rank, and that it was derived from the Harley Brumm sound. I also made the mistake of reporting that Schantz seems to known for "wild" rank names. The return message was a rather terse admonishment and lesson from Ken, a way he gets when confronted by inaccurate or absurd information. I have sought and recieved permission from our List Administrator to quote some of Ken's remarks because I thought you might find them of interest.   Ken List writes:   << Mike-   The German term "Brummbass" literally means "drone bass" and was occasionally used in the 'olden days' - actually it means exactly the same thing as "Bourdon" does in French! When the Germans used to use the term Bourdon they spelled it "Bordun" - which when pronounced in German sounds somewhat as "Bourdon" does pronounced in French!   There was one Schantz representative in the South (Al Lunsford) who seemed devoted to the term. If there were but one Subbass in the organ, he would have it called "Brummbass" - and if there were two, Brummbass would be the softer. I don't think the company ever used it outside of Al's organs. He is retired now, and we don't use the term at all so far as I know.   Your compatrios on this List is very much off base. Schantz if anything is far more conservative in stop nomenclature than most. He should consult old Schlicker and Holtkamp and Aeolian-Sknner lists. How about A-S calling a Vax humana by its German name "Menchenstimmen" or one company who used the Greek name for it "Anthropoglossa" ---------------------------------------------------------------------------= -----------   So there you have it folks. The final line of his message I did not copy here, but I will tell you it had to do with the accuracy of what I may read on this List. I think he was not at all amused by the suggested relationship between Harley sound and the Brumbass. nor the reputation for wild rank names. :-)   Cheers Mike Gettelman
