From: "Ross & Lynda Wards" <TheShieling@xtra.co.nz> Date: Fri, 7 Mar 2003 09:07:37 +1300   Ed, How do we comment to you on individual entries in your Encyclopaedia of Organ Stops?   I've yet to read through, but just glanced at random at your Dulciana = entry. My comments would be these: that Skinner is very wrong - a Dulciana is not = a string, muted or otherwise, as the harmonic structure is very different: a Dulciana always has a stronger fundamental than a string, and fewer = audible high harmonics. Second, that just as you can get a good Diapason sound = from an open metal pipe of down to 4" scale at CC, so too you can get a good Dulciana sound from a pipe up to a good 4.5" at CC. Even greater and lesser scalings may be possible. The difference in tone = is mainly caused by the mouth of the Dulciana being narrower than that of the Diapason. Wide, low cut-up gives good Diapason tone. Narrow, low-cut-up gives good Dulciana tone. Narrow, slightly-higher cut-up gives a more = flutey Dulciana, i.e. increases the fundamental.   Those are the sorts of remarks I'd make. Do we have the opportunity to = email you with these sorts of comments?   Congratulations on the herculean effort. I intend to enjoy every entry.   Ross    
(back) Subject: 16' Bourdon and 8' Principal From: "Steven Durham" <sdurham11@attbi.com> Date: Thu, 6 Mar 2003 12:55:46 -0800 (Pacific Standard Time)   List:   I have a three rank pipe organ I built in my home with the following specifications:   8' Stopped Diapason - Maas Organ Co. 4' Horn Diapason TC - Lyon & Healy 8' Muted Violin TC - Kimball   Because of space limitations, I'd like to add an electronic 16' Bourdon (12 notes) and an 8' Principal (12 notes) to my organ. I know nothing about electronics or where to start. I'd like to build it myself. Any suggestions out there? I'd appreciate any help possible. I'm on an extremely limited budget and can't spend hundreds of dollars on this project     Best Regards,   Steven Durham Portland, OR
