ELECTRONIC PLAYER PIANO WITH BASE AND TREBLE EXPRESSION EFFECTS

摘要

There is disclosed a system for encoding of bass and treble expression effects while recording from the keyboard of an electronic player piano wherein the intensity of the music being recorded is reflected in variations in the power of the acoustic waveform produced thereby. The key note or key switch actuations are multiplexed in a serial bit stream of data and stored in a shift register and then separately combined with the bass and treble expression data bits -in a format which, upon re-creation of the original musical presentation, results in a more faithful rendition of the original performance.
