TRACKER ACTION

Tracker action in a pipe organ is a mechanical set of levers and rods which directly connect the keyboard to the pallets (valves) underneath the pipes.

Tracker action is the earliest type of organ 'action' and also one of the most reliable.

Later pipe organ actions include pneumatic, electro-pneumatic and direct electric.

The great advantage of tracker action is that the organist is physically opening the pipe valves, or pallets when a key or pedal is depressed, giving much more sensitivity to the touch, or feel of the organ.

 

Many earlier tracker actions used iron/steel threaded rods on the ends of wooden rods, and unfortunately over time this metal rusts. This is often a cause for a complete overhaul, as the steel ends break off when the organ builder attempts to make an adjustment.

Phosphor-bronze has now been used in place of iron/steel for many years, and proves much more resilient to corrosion.

Small leather 'buttons' are normally used on the ends of the threaded rods to adjustment of tracker action. These leather buttons can perish and disintegrate causing problems with adjustment.

Other problems with tracker action can be caused by changes in humidity and temperature. The most usual problem being that of sticking notes. (Notes that continue to play when not wanted!)

Modern tracker instruments are not so vulnerable to these changes, and are much more reliable.

Simple adjustments will normally be sufficient to keep a tracker action pipe organ working well.
