Here, the microcomputers 4 and 15 which cooperate with each other functionally control the CD playback device 2 and the CD exchange mechanism unit 3 such as CD selection and cueing, and performance control means 41 and memory play. The RAM 42 for storing the music information as data, the music information corresponding to the skipped music is moved to the lowest rank position in the RAM 42, and the music information corresponding to other music stored in the RAM 42 is also stored in the RAM 4 respectively. The memory control means 43 for moving to one higher rank position in 2 and the music information newly stored at the time of storing the music information are stored in the highest priority position of the RAM 42 and the music information already stored in the RAM 42 is stored. The memory control means 44 is provided to move each one rank lower.

The operation of the present embodiment configured as described above will be described with reference to the flowcharts of FIGS. 2 and 3 and FIGS. 4 and 5 schematically showing the addresses and stored contents of the RAM 42. In the present embodiment, it is assumed that the RAM 42 already stores the music information corresponding to the music A to E, and the address is "1" to "5".

A memory play start instruction key 6 is used to instruct a memory play start. At this time, the contents stored in the RAM 42, the execution address data, and the final address data are as shown in FIG. 4 (a). When the memory play start instruction is given, the execution address data and the final address data are initialized (step S1). By this initialization, the execution address data is initialized to "1" and the final address data is initialized to "5" as shown in FIG. 4 (b). Then, the reproduction performance of the music A corresponding to the memory play data stored in the execution address is executed (step S2).

Subsequent to step S2, it is checked whether or not the performance of the reproduced performance song A is completed (step S3). This state is as shown in FIG. 4 (c), and the music to be played is shaded. When it is determined in step S3 that the performance has ended, the execution address data is incremented by 1 following step S3 (step S4). By executing step S4, the contents stored in the RAM 42, the execution address data, and the final address data become as shown in FIG. 4 (d). After step S4, it is checked whether the execution address data and the final address data match (step S5). The state of the address data at this time is as shown in FIG.

If it is determined in step S5 that the address data match, it means that the performance of all the songs to be played in memory has been completed, so that the process is executed from step S1 following step S5. When it is determined in step S5 that the address data do not match, the reproduction performance of the music corresponding to the music information stored in the execution address is executed following step S5 (step S6). In this case, the reproduction performance of the song B is performed. Here, it is checked whether or not the user has made a skip instruction by the data skip instruction key 8 (step S7).

If it is determined in step S7 that the skip instruction is given, the reproduction of the track currently being reproduced is terminated and the reproduction of the song C stored at the next address is started, but at this time, the address 〃2〃 , 〃 3 〃, 〃 4 〃, 〃 5 〃 perform the same operation as the so-called left rotate, and the music information corresponding to skipped music B is transferred to the final address 〃 5 〃. The song information corresponding to the songs C, D, and E is stored in the address "5" and moved to the addresses "2", "3", and "4" (step S8).

Following step S8, the final address is (-1) (step S9). The contents stored in the RAM 42 when steps 8 and 9 are executed are as shown in FIG. 4 (f). Subsequent to step S9, it is checked whether the execution address data and the final address data match (step S10). In this case, the address data when step S10 is executed is as shown in FIG.

If it is determined that the address data match, the performance of the music corresponding to the music information to be played in all the memory has been completed, so that the process is executed from step S1 and the next music information is arranged in the order of the arranged music information. The performance will be performed. If it is determined in step S10 that they do not match, the music C corresponding to the music information stored in the execution address is reproduced (step S11), and the memory play end instruction key 7 is used until memory play end is instructed. The process is repeated from step S3 (step S12).

Next, processing at the time of memory setting will be described. When a memory set is instructed by the memory set start instruction key 9, it is checked whether or not the memory play data stored in the RAM 42 is confirmed (step S21). It is assumed that the RAM 42 has already stored and determined the memory play data corresponding to the songs A to E. The stored contents of the RAM 42 at this time are as shown in FIG.

In order to secure a music information storage area in the RAM 42, the music information stored at the lowest final address is deleted (step S22). When step S22 is executed, the contents stored in the RAM 42 are as shown in FIG. 5B, and the music information corresponding to the music E is deleted and the music information stored at the address "5" disappears. Following step S22, song information corresponding to the song one rank higher is sequentially shifted and stored in the empty address (step S23). When the step S23 is executed, the contents stored in the RAM 42 are as shown in FIG. 5 (c), and there is no music information stored at the address "1".

The music information corresponding to the new music is stored in the address "1" which is vacant by the execution of step S23 (step S24). By the execution of step S24, in this case, the music information corresponding to the music F is stored as the address "1" as shown in FIG. This process is continued until the end of the memory set is instructed by the memory set end instruction key 10. Here, the explanation has been given from the state in which all pieces of music information are registered, but the same processing is performed even if all pieces of music information are not fixed.

In the above-described embodiment, the case where the music information as the memory play data is exchanged in the RAM 42 is illustrated, but a RAM for storing the address data of the RAM 42 is provided and the order of the address data may be exchanged. It is the same.
