Although it may sound like a sampled instrument, MrRay SeventyThree is still synthesized, as the sound it produces is 100% calculated in real time.
What characterizes this version of MrRay is a series of "imperfections" introduced in order to capture, with the highest possible fidelity, the sound of a Mark I. There are mallet noises, wooden noises, metallic artifacts and changes of volume for each single note. Also, the lower notes have a particular "growl" when you hit them hard, and when you hit more keys really hard, you'll hear them "vibrating", originally due to the instability of the harp assembly inside the real instrument.
