Re: Nomenclature for Diapason stops
[quote user="AllanP"]
John,
I compared the sound of your grand diapason with my Wurlitzer Open Diapason. Yours has a somewhat breathy sound (for want of a better description). Comparing your Melodia with the Wurlitzer Flute gives again the same effect except that yours has a somewhat breathy sound (for want of a better description).
I wonder what causes the difference in sound? The basic effect is very similar but when using an individual stop at 8', the Wurlitzer lacks the breathy sound. Is it possible that enclosure in the swell chamber causes this change in effect? Did you do your recording near the pipes? Of necessity, I listened to mine outside the chamber after the sound passes through a mixing room to allow the sounds to blend before reaching the console. Does higher pressure tend to remove the breathiness (which seems to give a more delicate effect)? When used in combination 8', 4', 2', the diapason chorus sounds very similar.
Discussion of these questions may lead to some insight as to the fundamentals of organ design. It seems that selecting all Reuter pipes as you have done makes the ranks blend better.

Allen, you are hearing the difference between theatre sound and church sound. Wurlitzer pipeswould not have a "breathy" sound-Wurlitzer didn't do things like that. Part of it iswind pressure, part is simply the voicing of the pipes themselves. I don't know if you could drop the pressure on your organ and get that sound. Probably not;at a lower pressure, the pipes may not even sound, or may struggle to produce a sound.
Some revoicing is possible with any pipe, but only to a certain extent.A Wurlitzer diapason is not going to sound like a Barogue principal, no matter what you do, short of completely remaking the pipe, which is a completely different matter.
