<P>PROBLEM TO BE SOLVED: To realize a musical performance data series converting program easily enabling reverse reproduction of a musical performance data series and to easily performs conversion into the musical performance data series in a short time. <P>SOLUTION: Through processing at steps S16 and S18, a source musical performance data series is read forward to sequentially update generation style control data in a current value array area, and after the musical performance data series is read out, generation style control data left in the current value array area are written to the head of a reverse reproduction buffer area. Then the source musical performance data series is read backward through processing at steps 22 and 24, processed, and sequentially written to the reverse reproduction buffer area. In this processing, note-on and note-off data are converted into note-off and note-on data respectively. Generation style control data on a musical sound are converted to a retrieval value in the head direction of the source musical performance data series. When retrieval ends in failure, the data are converted to initial values. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
