Abstract: An organ includes keys, a windchest in fluid flow communication with a wind supply. A windchest pallet disposed inside the windchest and connected to the key. An auxiliary chamber is independent from the windchest and in fluid flow communication with a wind regulator. An auxiliary pallet is disposed inside the auxiliary chamber and connected to the key. A first adjustment element controls wind generated from the wind regulator. A bias element urges the auxiliary pallet in a closed position. A second adjustment element controls tension exerted by the bias element on the auxiliary pallet.

Abstract: A console for use in playing an electronic musical instrument. Two manuals are slidably arranged on a stationary frame or desk, to slide sideways toward and away from each other. Each manual carries various keys and other movable control elements to be operated by one arm-hand-finger of the player. On each manual, keys for individual tones are arranged in rows extending front to back, toward and away from the player, rather than in rows extending from side to side as in a conventional piano keyboard. Each key is wide enough so that two fingers of the player may rest simultaneously on the key. In addition to these rows of keys, each manual has other special keys or movable elements, some arranged for operation by the little finger, some for operation by the thumb, some for operation by raising or lowering the hand, for changing the nature, quality, duration, octave, or other characteristics of the sound produced.
