Sound Technology

Allen's Proprietary DSP Technology


DSPs are programmable coprocessors that manipulate digital signals within the organ. The advanced architecture, processing speed, and dedicated instruction "sets" programmed into the Allen DSPs execute millions of instructions per second, resulting in real-time pipe organ sounds.

GeniSys Display


Advanced full-color touchscreen control provides organists access to the many functions available from a modern church organ console with an intuitive interface and unmatched ease-of-use.

Stop-by-Stop & Note-by-Note Voicing


Through advanced technology, Allen organs can be voiced both on a stop-by-stop and note-by-note basis, as found in pipe organs. This capability assures that the Allen Organ can be matched to the room in which it is installed, as well as specific musical needs.

Advanced Midi Capabilities


With full MIDI capabilities, the Allen organ's musical versatility becomes nearly limitless.
Compatible with GM, GS as well as XG MIDI, the Allen console is a perfect controller for today's blended worship requirements.

Voices Changeable Via CD ROM



Allen's exclusive SoundMatrix™ technology ensures that the organ will serve the needs of any dynamic music program. The organ's sounds (stops) are stored in massive dynamic memory. These voices can then be changed, even after the organ is installed, as musical styles require. This unique capability acts as an "insurance policy" against tonal obsolescence.

Air Regulator™


In a pipe organ, as more stops are played, the winding fluctuates momentarily as the air pressure builds up. This results in interesting sound nuances (pitch fluctuations) that have become an important part of pipe organ sound. With Air Regulator, Allen's digital voices react in this same manner; a very sophisticated, but subtle pipe organ sound nuance.

Acoustic Portrait™ - Actual Sampled Acoustics


Acoustic Portrait begins with a sampling process using impulse responses that measure an actual room's acoustic properties. These measurements are then stored in the organ's computer memory. Through an advanced real-time mathematical process called convolution, the acoustics of the sampled room actually become an integral part of the organ's sound, producing a noticeably smoother, more natural result than synthetic reverb. Allen engineers have recorded the acoustics of cathedrals and other acoustically desirable buildings throughout the world. With advanced digital signal processors (DSPs) and low-latency convolution algorithms, Acoustic Portrait reproduces the true acoustic response of each original room with stunning realism! Each Quantum Organ features 10 different Acoustic Portraits, ranging from intimate rooms to cavernous cathedrals.

Allen Organ Suites


Classic Allen - The "signature" specification that made Allen the world's favorite organ! Nearly 40 years before the advent of Stoplist Library™, Allen tonal directors created the specifications of Allen digital organs by selecting their favorite samples from fine pipe organs throughout the world. Tens of thousands of Allen owners know and love this legendary sound.

English Cathedral - Characterized by Diapasons and weighty reeds, this style of organ building was brought to its height by renowned 19th-century British organ craftsman Henry Willis. Numbered among his greatest works are the organs of St. Paul's Cathedral, London and The Royal Albert Hall.

Cavaillé-Coll - Broad Montrés and dominant fiery reeds are integral parts of Aristide Cavaillé-Coll's tonal scheme. The genius of this most-famous French organ builder was his creation of the symphonic organ. The "Grande Orgue" became an extension of the orchestra and "a new sound for a new age.

Schlicker - The Schlicker Organ Company specialized in instruments of Neo-Baroque design supportive of contrapuntal music. The European heritage of this American organ builder is readily evident in the sound of their instruments.


Arp Schnitger - One of the most renowned organ builders of the 17th century, Arp Schnitger instruments are monuments of the North-German School of organ building. Fine examples of this builder's organs still exist in Germany where Allen's sound engineers captured their tonal beauty.

Aeolian-Skinner - Under the tonal direction of G. Donald Harrison, this company developed the American Classic tonal design, characterized by firm and articulate principals, bright mixtures and French-style reeds. Its versatility enables the American Classic to authentically perform a broad range of musical styles.

Wurlitzer - "The Mighty Wurlitzer" was perhaps the "gold standard" of theatre organs during the silent movie era. Due to Wurlitzer's "assembly line" approach to organ building, various ranks, for the most part, sounded very similar from organ to organ.

Morton - Morton theatre organs "evolved" over the course of the silent movie era. Our digital samples are from a late 1920s organ that used higher wind pressures than the typical theatre organ and was known as one of Morton's "jazzier" instruments.

Barton - Barton was mainly known in the Midwest area in the United States. Their most famous instrument was the theatre organ installed in the Chicago Stadium. Barton's were known for their "aggressive" voicing style.

The Allen Keyboard

Individually Adjustable and Felted Keys


The Allen keyboard is designed to allow the musician to feel the music. These keyboards are built with a level of quality that is the envy of the industry. Each key stick is constructed of wood, felted pivot points and can be individually adjusted keep them consistent over the long-haul.


Adjustable an Felted Keys

Reed Switch Key Contacts - (or OST™ Optional)


The key contact, while unseen, is an important part of any organ. If one fails during a performance, the entire musical program can be compromised. Allen has introduced a maintenance-free system in which a sealed reed switch is engaged by magnet. Neither dust nor the environment will compromise your music program with an Allen Organ.

In addition, if you require velocity sensitive keyboards for MIDI voices, Allen's Optical Sensor Technology (OST™) is the perfect solution. With infrared technology, this contactless system self regulates itself each time the organ is turned on for dependable velocity sensitive control of MIDI voices.

Reed Switch Key Contacts

Ivora Naturals & Wood Sharps - Optional


The Allen keyboard is designed to allow the musician to feel the music. Since Allen manufactures keyboards, its keyboard, like the Allen console, can be customized to meet the look and feel desired for each installation. Whether the choice is the optional Ivora naturals or wood sharps, Allen can meet any need.
