ALLEN ORGAN COMPANY
For more than fifty years--practically the entire history of electronic organs--the Allen
Organ Company has sought to build the finest organs that technology would allow.
In 1939, Allen built and marketed the world’s first purely electronic oscillator organ.
The tone generators for this first instrument used two hundred forty-four vacuum
tubes, contained about five thousand components, and weighed nearly three hundred
pounds. Even with all this equipment, the specification included relatively few stops.
By 1959, Allen had replaced vacuum tubes in the oscillator organs with transistors.
Thousands of transistorized instruments were built, including some of the largest, most
sophisticated oscillator organs.
Only a radical technological breakthrough could improve upon the fine performance of
Allen’s solid-state oscillator organs. Such a breakthrough came in conjunction with the
U.S. Space Program in the form of highly advanced digital microcircuits.
Your MDS organ is the product of years of refinement in digital techniques by Allen
engineers. It represents the apex of computer technology applied to exacting musical
tasks. The result is an instrument of remarkably advanced tone quality and
performance.
Congratulations on the purchase of your new Allen Digital Computer Organ! You have
acquired the most advanced electronic organ ever built, one that harnesses a modern
computer to create and control beautiful organ tones.
Familiarize yourself with the instrument by reading through this booklet. The sections
on stop description and organ registration are intended for immediate use as well as for
future reference.
