System for encoding the effects of low relative to the notes and to the notes acquired during the recording on the basis of the keypad of a piano mechanical electronique

摘要

P the system according to the invention is used to encode the effects of low relative to the notes and to the notes acute during the recording of the keypad 10 of a piano mechanical electronics in which the intensity of the music during recording reflects the energy variations of the waveform transmitted by the piano. The actuation of the switches of the keys 11 - 1, 11 - n are multiplexed at 12 in a stream of data bits in series and stored in a shift register and then combined separately with the data bits of expression in a format which, during the re - creation of the initial presentation of music, results in a more faithful of the piece of music. / p
