Crescendo Pedal

On most electric action instruments there is a pedal to the right of the swell pedal called the "crescendo pedal." This device brings on stops and couplers gradually from the softest to the loudest sounds on the instrument. The crescendo pedal operates within the instrument, so the stop knobs do not actually move. Therefore it is impossible to tell except by ear what stops are engaged and when. Also, in many instruments the order and timing of the stops in the crescendo pedal cannot be changed by the player but must be done by a technician. The crescendo pedal is another quick way to get full organ.
