Using Console Devices: Items
Some three-manual organs are equipped with a device that exchanges the relative position of the Choir and Great. In effect, it transfers the Choir (the lowest manual) to the normal position of the Great (the second manual up), and it transfers the Great to the normal position of the Choir. The stops and local pistons are then associated to the new position of the manual; manuals, stops, and locals are all transferred.
This is useful for at least two reasons. If you wish to practice on the Great, you may tire of always reaching to the second manual. The “Choir-Great Transfer” piston brings the Great to within easier reach. Secondly, some national styles in some periods of organ building place the manuals in a logical ascending order of volume: the Great first (bottom), followed by the Choir, and finally the Swell.
Cancel, pull a stop on the Great, press the Choir-Great Transfer, and then play on the lowest manual.
