(back) Subject: Fake Mixture question From: "Dave McClellan" <deep_tremolo@hotmail.com> Date: Sun, 30 Dec 2001 08:41:17 -0500   I wonder if this idea has any chance of working. Feedback and suggestions =   wanted - but please, no flames!   I was thinking about building a "fake mixture" for the Great Manual on my residence instrument. I would use the Swell Nazard (61 pipes) and Great Oboe Gamba (85 pipes - 4' and 2' octaves currently not used). The Great stoplist would then read:   Great 8' Open Diapason 8' Gamba (4' and 2' octaves not used) 8' Clarabella 4' Octave (idependent rank - Swell 4' Principal) 4' Wald Flute (from Clarabella) 2' Fifteenth (independent rank) 1 1/3' Larigot (from Swell Nazard) III Mixture 2 2/3' 8' Trumpet Chimes 16', Unison Off, 4'   I was thinking about a low-pitched Fourniture type mixture (12-15-19).   Any suggestions? Suggested breaks? Remember that the highest pitch I = have available is 2 2/3' for quints and 2' for octaves.   Thanks, Dave             _________________________________________________________________ Join the world=92s largest e-mail service with MSN Hotmail. http://www.hotmail.com

Remember that the highest > pitch I have available is 2 2/3' for quints and 2' for octaves. Building a "mixture" like this was done with electronic organs 30 years ago. I have one organ here in Dallas that has such a mixture. The base ranks are on the console as playable ranks just as you are thinking. The mixture uses a separate keying matrix based on the pitch you wish to start. I am too sleepy this morning to describe it accurately, but when the mixture stop is turned ON, the mixture keying transistor turns ON and passes keying voltages to each of the notes in the diode matrix. The only problem that I see right now may not be a true problem, and that is the blending of the two voices. That should not be your major concern, since you are only trying to expand the available resources into something that is useful to you as the only critic of the finished product. Go for it. Try your idea and let us know how well it works. F. Richard Burt dorian.organs@verizon.net ..
