Of Interest
There will be two operating modes selectable by thumb pistons with LED indicators. The first mode is Mode Francais, the second is American Mode. The two modes are interlocked so that only one can be used at a time.
Mode Francais uses the following hookdown pedals in the French Symphonic tradition:
Pedales de Combinaison:
Effet d'orage Grand Orgue sur la machine Tirasse Grand Orgue Copula Grand Orgue/Grand Orgue Tirasse Positif Copula Positif/Grand Orgue Tirasse Recit Copula Recit/Grand Orgue Anches Pedale Copula Recit/Positif Anches Grand Orgue Octaves graves Grand Orgue Anches Positif Tremolo Recit Anches Recit Tremolo Positif
The combination action will not be able to control the functions on hookdown pedals, i.e., any of the Pedales de Combinaison when in Mode Francais.
The American Mode relies on a solid state combination action for changes in registration. When in American Mode the positions of the Pedales de Combinaison will be ignored. American Mode has the following drawknobs arranged above the top keyboard and are affected by the General Pistons:
Grand Orgue/Pedale Positif/Grand Orgue Positif/Pedale Recit/Grand Orgue Recit/Pedale Recit/Positif Recit Tremolo Octave graves Grand Orgue Positif Tremolo Orgue sur la machine
Balanced Swell Pedals: Expression Recit, Expression Positif
Key Action: Direct mechanical (tracker), except for certain large bass pipes.
Servopneumatic Lever: This provides a pneumatic assist (similar to a Barker Machine, but more refined) to the Grand Orgue key action. It also allows the addition of the "Octaves graves" coupler to the organ. This coupler couples the servopneumatic lever to itself one octave lower. Therefore it couples the Grand Orgue itself at sub-octaves, and any division coupled to the Grand Orgue also appears on the Grand Orgue at sub-octaves.
Stop Action: Electric solenoid.
Combination Action: A modern solid state system with multiple levels of memory. Numerous pistons, toe studs, and reversibles suitable to an organ of this size. There will be room for two rows of toe studs above the Pedales de Combinaison.
Keydesk: Built into the front of the lower case, three manuals and pedals; manuals 58 keys, CC-a3, naturals of bone, sharps of ebony; flat pedalboard, 30 keys, CC-f1, naturals of maple, sharps of ebony.
Front Pipes: All front pipes to be of hammered spotted metal.
