Who were the Midmer Losh engineers (unsung heroes) who figured out how to do this and wire it. They are the ones who should have a plaque on the wall somewhere. I can't conceive how they did this without 3D cad to stuff all this into the available spaces.
Technically, you could include the combination rooms in the stop signal flow. Yet another step. Hoping that they find a way to graft into the system a combination action someday.
I am constantly amazed by the complexity of this organ. I always thought that the signal went from the key right to the appropriate wind chest, but now I know there is a hell of a lot more to it. As the old controls are replaced by newer circuitry, how much of the original will be kept? How simplified will the new circuitry be?
There never was a three manual console even though the junction board showed three manuals. There was a two manual Moller console which was not saved as far as I know. The five manual of course is on display and will be restored at some point. Yes the plan is to have the whole organ running on Opus 2 at some point.
IIRC, while Vox Maris is the loudest *instrument*, due to a technicality around the term "organ stop" (the Vox Maris has no stop controls) the ML's Grand Ophicleide retains its title.
Concerning the signal flow, how much of a delay is there from when a key is pressed to when a note sounds? Also I notice some meters and switches near the top of the console. What were/are they used for?
The delay is hardly noticeable...even the closest pipes are quite a ways from the console and there's a slight lag simply because of the speed of sound! Believe it or not the all those pneumatic stages worked so fast you didn't feel a delay, as such. There are a couple of voltmeters at the top of the console which aren't used any more and some switches for the old telephone system.
Why exactly is the relay box pressurized and at what pressure would it be at while the organ is operating? Would it be at the pressure of whatever ranks it’s supplying?
The relay room is pressurized because that's how the note pneumatics operate. I'm not sure what the actual pressure is inside the room but it has nothing at all to do with pipe pressures.
I don't know that it ever existed, I don't think there's any picture of a three manual console hooked up to this organ, despite there being a three manual junction. The original test console was a two manual Moller which is long gone.
It's amazing that this works at all.
WOW, so the keyboard works somewhat like a crossbar telephone switch.

Such a big difference from this side and the digital side.

From a recent video I seen, the combination action does work now
Already done!
You should post a video of the current combination action and how that works.
That's on the agenda for the next round of videos.
I imagine that was a smart move for offset chest with or without basses of certian ranks
Could we have a look at the 64’ diaphone?
There are already some videos out there with the 64', but I do plan to feature it next time.

Is there a plan to replace the entire relay/combination system of the organ with modern digital/computer equivalents like Opus 2?

I thought Vox Maris in South Korea took the title of the loudest organ in 2011.

What's the delay from keypress to sound? With all those relays inbetween i imagine it's several ms in delay.
With the distance from the chambers to the console it isn't detectable.

Oh ok.
One day when it's fully restored I'll make my way up there to hear it.

What happened to the nooks and crannies video?
In another comment he said it was replaced by the Great and Swell blower rooms video
What happened to the old three manual console?

@@chrisnagorka5199 oh
Have the original three manual testing console and the five manual console been kept and will they be restored?
You referenced a nooks and crannies video, which one is that please
It was replaced by the Great and Swell Blower rooms video, which showed the same thing but with a little better camera work.
Do you know what material was used for all those switch and relay contacts?
Probably silver wire, I can see if it's specified in the contract.
Thanks! It's cool you have access to that kind of data!
