Crescendo pedal

This gives the device a much longer field of operation than the modern crescendo pedal, thus making the dynamic change more smooth and gradual.

The order in which the stops were activated by the crescendo pedal was set by the organ builder and could not be modified by the organist.

This was the case until the later part of the twentieth century, when computerized devices were incorporated into console design, allowing greater customization of registration through more sophisticated combination actions.

As a result, in organs with these devices, the stops controlled by the crescendo pedal are usually customizable, as is the order in which they are activated.

Reed organs and harmoniums of the late 19th and early 20th centuries often had a similar mechanism to a crescendo pedal.
