Winfried Dulisch writes in image hifi (4/2023) about the recording of my composition The Richter Scale: “The system developed by Steinway & Sons is more than a piano automaton for passive music connoisseurs. Spirio reproduces the touch and other subtle nuances of the pianist. The recording version Spirio/r records live and can instantly reproduce what the pianist has just played. (…) Ji Liu’s recording of The Richter Scale (CD:030/Indigo) draws its stirring power from the pianist’s playing against and with the Spirio/r technology.”
