MUSICAL INSTRUMENT CAPABLE OF RECORDING PERFORMANCE AND CONTROLLER AUTOMATICALLY ASSIGNING FILE NAMES

摘要

An automatic player piano has a recorder for recording a performance into a music data file: when a set of music data codes expressing the performance is prepared, a file name is automatically assigned to the music data file through a subroutine program; while the subroutine program is running, the maximum integer, which forms a part of a file name already stored in a memory unit, is determined, and the integer next to the maximum integer is introduced into the file name in so far as the maximum integer is less than the limit of a numerical range, whereby the automatic player piano makes the order of creating the music data files clearly readable from the tile names: when the maximum integer is equal to the limit, a skipped integer is introduced into the file name, whereby the integers in the numerical range are economically reused.
