Abstract
Music encoding and decoding apparatus which divides a keyboard instrument into groupings of designated lengths such as octaves wherein each octave is scanned, either in sequence or on triggering of a key in that octave; the apparatus includes a master encoder which encodes a key closure, the encoding being in the form of a word of multiple bits having a specified word length. The apparatus further encodes the expression of the note. The expression constitutes a portion of the word. Decoding apparatus is likewise incorporated. It reverses the sequence and drives a solenoid for operation of a keyboard instrument.

- first means responsive to a struck note on a selected portion of an instrument, the instrument being divided into two or more selected portions and therebeing a first means associated with each of the portions of the instrument and said first means scanning a specified number of potential notes in the selected portion of the instrument and forming a signal indicative of a musical change in the selected notes;
- and,
- a master circuit means connected to at least two of said first means for forming an output signal identifying which of said first means has a signal indicative of a musical change and also including a signal indicative of the change;
- said signal having a multibit format suitable for transmission and decoding.
