When the sequence data of the pure sequence file (NO in step 85), the obtained sequence data is the sequence data contained in the sequence file with the tone color data, and then proceeds to step S7. Here, the tone color data of the obtained tone color data sequence file is changed to the previously registered tone color data, and a new tone color data sequence data is created and stored in the system RAM3. That is, the obtained tone color data of the attached tone sequence file is replaced with the tone data created in step s3, and the information assigned to the tone is edited by using its tone data number to create a new The sequence data of the attached voice data is stored in the music file memory area in the system RAM3. By playing this attached tone data sequence data as described above, it is possible to play a song using the newly registered tone color data. When a string file is created (NO in step S2), the process proceeds to step S8 to create a string slot case as shown in FIG. 4C. That is, the sound data sampled in step 81 is cut out as part of a long string of data, or additional processing of packets or adjustment of a level (level) is performed to produce a long string of data. Then, create information such as the start and end of playback, pitch shift, or effects, and create time interval information to create sequence data.

Description of the invention (20) The address of each tone waveform data of channel and L channel. Then, when the sequence data included in the sequence file is played, in the case of stereo sound, the tone waveform data of the R channel and the L channel are read out, and the tone waveform data of the R channel is input to the R-ch mixer 48. The tone waveform data of the L channel is input to the L-ch mixer 46. In the playback of the string file in FIG. 4C, the system CPU1 writes the leading part of the long string data into the tone RAM 45 through the memory interface circuit 53 before the string file is played. In the case of long strings of stereo samples, the R and L channels are allocated in different areas and read out simultaneously. The following is a description of the production or conversion process of the music file in FIG. 8 of the portable communication terminal of the first embodiment in the case of using the tone color data produced by using the stereo sampled waveform data as the material to play the music file. Dissimilarities. That is, when performing processing such as displaying the packet or tone change of the sound data sampled by the stereo processing unit 8 on the display unit 4, the waveform data of the left and right channels of the stereo sample are displayed on the display unit at the same time, and the processing is cut out. The process of setting the start point and end point of the loop is performed on the waveform data of the left and right channels together. To the sound data cut out through this process, a tone number is added, and when the tone data is stored in the tone data storage area in the system RAM3, an identifier (R, L) indicating that it is the left or right of the stereo sound is added. As mentioned above, according to the portable communication terminal of the second form, the stereo sampled sound waveform data is used by the waveform memory of the WT sound source, which can be played back. -23- This paper size applies to China National Standards (CNS) A4 specifications (210 X 297 mm) Iy m 1223536 A7 B7
