ABSTRACT:
A portable modular music recording device which simply and unobtrusively attaches to a keyboard instrument for purposes of recording live musical performances; and an efficient music microcomputing system in which the captured musical data is digitized and further analyzed to determine note and note expression information when a key has been played. In the modular keyboard device, key and key expression data is captured by means of reflective couplers mounted in the keyboard device, and the information is transmitted to the processing unit. Microcomputer instructions refine the data to a format suitable for serial transmission via a computer-compatible link for ultimate scoring and recording.
