Enhanced Virtual Resonance Modeling (VRM) – the distinctive reverberation generated by the concert grand piano
VRM calculates the various states of the strings for each of the 88 notes of the keyboard, from one instant to the next, and timing and depth of damper pedals pressed to recreate the sound of an acoustic piano. Enhanced VRM also calculates aliquot resonance in the upper octaves, and the full resonance of the soundboard, rim and frame. This technology allows for vivid, bright, richly varied expression that reflects the limitless number of factors inherent in piano performance.
Aliquot is a stringing method for pianos that uses extra, un-struck strings in the upper octaves to enhance the tone. These strings sympathetically vibrate with other strings in an acoustic piano, resonating with overtones and adding richness, brilliance and complex color to the sound. Since they do not have a damper, they will continue sounding even after you release your hands from the keyboard.
