Acoustic Portrait™ - Actual Sampled Acoustics

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!
