WHAT IS “CHIFF?”
On a pipe organ, when a flue stop such as a
Diapason, String or Flute is drawn and a key is
depressed, a valve opens, and air escapes through
the hole in which the pipe sits, allowing the pipe to
sound. When the air fi rst enters the pipe, there is
a small, short burst of upper harmonics before the
tone develops fully. The term “Chiff ” was coined by
pipe organ makers to describe this sound.
NOTE: The Parameters labeled (Pi) are Pipe
Parameters. You must Record these
Parameters to a Custom Pipe if you want
their settings to be remembered the
next time the instrument is turned “ON.”
See page 128 for instructions on how
to do this.
WHAT IS “PIPE VOICE IMAGING?”
The pipes of a pipe organ are arranged into
sets called ranks. Each ranks consists of pipes
representing a specifi c sound on the organ - Open
Diapason, Trompette, etc. (In keeping with the
diff erent philosophies of organ sound, many organ
stop names are of European origin; hence the use
of French, German, Dutch, etc.)
The pipes of each rank are supported by an
assembly called a chest. The pipes can be arranged
in many different ways on the chest. The pipe
arrangement chosen by the maker depends on
several things - aesthetics, musical, etc. - but the
four most common ones are shown on the left.

immediate left are sometimes referred to as
“C-C#” placement due to chromatic notes being
separated.
