Despite playing a borrowed Hammond B-3 many moons ago, I am a virtual klingon when it comes to tracker organs. My apologies for this rudimental post; I find I tend to remember things better when I write them down.
1. WHAT DOES TRACKER ACTION MEAN?
Tracker action means that all the connections in the organ are mechanical rather than electrical. It is similar to the linkage in a manual typewriter.
2. WHAT ARE TRACKERS?
Trackers are slender rods which connect the keys to the valves under the pipes. ...
3. WHAT ARE THE ADVANTAGES OF TRACKER ACTION?
LONGEVITY - While electric and electropneumatic parts have a relatively short life span and often require major overhauling or replacement, tracker parts are designed and made to last for centuries.
TRACKER PARTS ARE NEVER OBSOLETE - Electric components are rapidly changing as technology expands. This makes replacement parts difficult or impossible to find. Tracker parts are always available because they are being made today the way they have been made for centuries.
4. WHAT DOES THIS MEAN FOR THE ORGANIST?
Sensitivity! As soon as you touch a key something happens. It's as if the organ were alive!
For the organist this translates into greater variety in articulation and more control of pipe speech.
