Barker lever

The Barker lever is a pneumatic system which multiplies the force of a finger on the key of a tracker pipe organ.

Displacement receiver

Examples of displacement-responding sensors include the mechanical action of tracker organs, as well as the force-sensing resistors found in music keyboards that had polyphonic aftertouch capability.

Hyde Park Reformed Dutch Church

In 1885 the last major renovation to the church, the addition of an Odell tracker pipe organ, came.

Organ building

The organ builder usually receives a commission to design an organ with a particular disposition of stops, manuals, and actions, creates a design to best respond to spatial, technical and acoustic considerations, and then constructs the instrument.

Tubular-pneumatic action

Until the advent of the tubular-pneumatic action, all organs used a system of levers and wooden rods called trackers to transmit the action of the keys and stops to the valves contained within the windchests.
