PURPOSE:To decrease the quantity of music playing data, by setting a fixed length data area in response to a music tone to record the music name, the timer data on the generating time point of a music and the on-time data on the duration of a music respectively. CONSTITUTION:An event frame EF is set at the byte fixed length, and a frame EF is produced in response to the operation of a key from ON through OFF. The timer data TMD, key code KC, touch data D and on-time data OND are written into the frame EF. Both data TMD and OND are calculated in accordance with the even intervals. When the data TMD is larger than the TDMmax, a timer data extending dummy event frame EF is produced. While a key is turned off at a time point when the ONDmax passed in case the OND is larger than the ONDmax. Then the processing is carried out by judging that the key is turned on again at the same time point. |
