Definitions:

Stop A complete set of pipes dedicated to a single manual, or keyboard and corresponding to a dedicated stop knob. This set of pipes may be comprised of 61 notes (in manual divisions,) or 32 notes in the pedal organ. It is important to note that a stop may be constructed of more pipes in the case of a Mixture, where three or four pipes sound per keyboard note played. Often this term is incorrectly applied to a console register that is unified from another stop, as an extended register such as the 16’ Gemshorn.

Rank The term applied to a stop of a specific pitch level. Usually considered the same in number as the stops of a given division. Except in the case of mixtures, where multiple ranks play as a single stop.

Console Register All stop controls (drawknobs) and coupler controls (tablets and drawknobs) are considered Console Registers. It is a term applied to any device attached to the console that activates a stop control, coupler or registration circuit (such as swell shade controls).

Ahlborn-Galanti Digital Module

The electronic stops in the organ are generated from the Ahlborn module. This unit receives MIDI signals from the Multisystem, and plays selected stops through speakers located in the Swell chamber and behind the Great windchest. All stops in this module are custom-configured for this installation, and voiced to blend with the pipework in each division.
