Quad Suite™ provides the versatility of four separate and distinct organs in one console. Choose from American Classic, Neo-Baroque, English Cathedral or French Romantic for the stop list that perfectly complements your music. Each specification is comprised of unique pipe samples from the world's finest examples of each major organ-building style. The touch of a button changes the entire organ to the stop list of choice! An Orchestral specification, perfect for blended worship, is also available as an alternative to the English Cathedral specification. In addition to a complement of traditional organ voices, the Orchestral specification offers many popular sounds typically found in external MIDI modules such as: Strings, Piano, Brass, Woodwinds and Percussion.


Stoplist Library™ — All Renaissance Quantum™ organs include tonal specifications from Allen's Stoplist Library™. Two-manual Quantum organs (and the Quantum Q300, QL320e and QL320i three-manual organs) feature four QuadSuite™ voices: American Classic, French Romantic, Neo Baroque and English Cathedral (or an Orchestral specification in lieu of English Cathedral). Larger Quantum three- and four-manual organs feature all six Stoplist Library™ voices: American Classic, Cavaillé-Coll, Schlicker, English Cathedral, Orchestral and Arp Schnitger. The Orchestral specification is perfect for blended worship. In addition to a complement of traditional organ voices, the Orchestral specification offers sounds typically found in MIDI modules, such as Strings, Piano, Brass, Woodwinds and Percussion. The Orchestral voice is not available as the default specification.


Acoustic Portrait™ — Quantum instruments are the only digital organs to bring the science of sampling to acoustics! Ordinary electronic reverb is a synthetic imitation of acoustics "applied to" the sound, not created as an integral part of it. Acoustic Portrait produces the real thing in exacting detail!

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 processors (DSPs) and patented 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.

And we don't stop there! We've even applied convolution acoustics to faithfully recreate how expression shutters affect a pipe organ's sound. We call it Real Xpression™ and when you hear it you'll know why. It's not just a change in volume used in other digital organs, it's the same thrilling feeling you get when you hear a pipe organ really open up!
