On looking at the console of a modern organ the observer will be struck by the fact that the familiar draw-stop knobs have disappeared, or, if they are still there, he will most likely find in addition a row of ivory tablets, like dominoes, arranged over the upper manual.
All these Combination Pedals and Pistons move the draw-stop knobs, showing a valuable index of their position to the organist.
Arranged in two double columns on the left-hand or bass jamb are 48 draw-stop knobs for the Couplers and Tremulants.
Once this appliance was thoroughly appreciated, the way was opened to dispense altogether with the mechanism that connects the key with the pallet (or the draw-stop knob with the slider), and to put in its stead tubular-pneumatic or electro-pneumatic action.
