Title: Music playing data array converting program
Inventor: FURUMOTO YUKI
IPC: G10H1/00
Filed: 2003-02-27
Abstract: <P>PROBLEM TO BE SOLVED: To accurately convert a playing data array having a plurality of tracks into a music playing data array for reverse reproduction.  <P>SOLUTION: Even data are reversely converted and written to a reverse reproduction buffer area. The longest track of the music playing data rows having the plurality of tracks is retrieved and its end timing is regarded as the end time of the whole musical piece. The value of difference between end timing of each track and the end time is calculated as an offset time. The offset time is added to the time difference from the timing of the event data right before the end to the end timing to calculate the timing of event data right before the end and write it to the reverse reproduction buffer area. The timing of the event data is calculated by using the timing of the event data right after the event data and the relative time difference between event in order from the event data right before the tail of the reverse reproduction buffer area and written to the reverse reproduction buffer area.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
