             Playing aids have always reflected the
            music of the period. Many organs have no playing aids, some are
            fitted with primative fix combination pedals, and others have
            a modern instantly changeable combination system. The use of playing aids can add another dimension
            to the music, providing the organist with a palette loaded with
            musical colours and textures. 
            Today, modern technology makes almost
            anything possible. So was born the piston stepper and sequencer.
            The piston stepper is a simple aid that
            allows advancement through the general pistons using NEXT and
            PREVIOUS pistons. The NEXT piston automatically advances the
            registration to the next general piston setting. The PREVIOUS
            piston allows movement backwards through the general pistons.
            The stepper display provides a visual indication of the exact
            position and displays the level and general piston number.  |
