An Infinitely Sustaining Piano Achieved Through a Soundboard-Mounted Shaker
William Reid Thompson, Edgar J. Berdahl · 2021
This paper outlines a demonstration of an acoustic piano augmentation that allows for infinite sustain of one or many notes. The result is a natural sounding piano sustain that lasts for an unnatural period of time. Using a tactile shaker, a contact microphone and an amplitude activated FFT-freeze Max patch, this system is easily assembled and creates an infinitely sustaining piano.
