Abstract
An automatic musical performance device including storage circuits, read out control circuits, and conversion circuits, wherein the storage circuits store a series of musical note data. Each of the musical note data is represented by multi-bits whose number is dependent on its own use frequency which means a degree of repetitive use of the data in a music. The read out control circuits read out the musical note data from said storage circuits and supply the musical note data to the conversion circuits. Then, the conversion circuits perform the code conversion of the musical note data to other musical note data whose number of bits are independent of their own use frequency. In the automatic musical performance device, musical sounds are produced or key depressing positions are indicated in accordance with the musical note data from the conversion circuits.
