Due to overwhelming product demand, the Allen Factory experienced rapid growth since the early 1950s. In 1953, an air-conditioned silk mill was purchased in Macungie, Pennsylvania, and the Company's manufacturing was relocated. This facility became the first air-conditioned commercial woodshop in Pennsylvania. Today, with significant expansions to the original site, and more than 250,000 square feet of state-of-the-art manufacturing facilities, Allen is the largest vertically integrated church organ builder in the world!

In 1969, Allen Organ Company partnered with North American Rockwell on a project that went on to change the world of music. Using technology developed for the Apollo Space Program, the companies packed the power of thousands of transistors into 1/16 of a square inch and used those transistor functions to store pipe sounds. For the first time, an electronic instrument recreated actual pipe organ sound using digital technology instead of merely imitating it with the older, analog method. It was the birth of sampling and the basis for virtually every recorded sound we listen to today.

The First Digital Musical Instrument

First Allen Digital Organ

The world's first digital organ, now in the Smithsonian, was originally built and installed, by Allen, in St. Andrew's Evangelical Church of Easton, PA in 1971. The church replaced it with a larger Allen in 1994.
