[0024]
Next, an operation procedure for creating new song data will be described with reference to FIG. FIG. 3 is a flowchart showing a new song data creation process executed by the CPU 11.
[0025]
Creation of new song data is executed when the NEW button 31 is pressed. When the NEW button 31 is pressed, it is confirmed whether or not the current song data exists (S31). As a result, when it is determined that the current song data exists (S31: Yes), a song effect patch set including a plurality of song effect patches stored in the song management data of the current song data is read from the removable medium 14. The read song effect patch set is copied to a temporary location in the RAM 13 (S32). Conversely, if it is determined in S31 that the current song data does not exist (S31: No), the song effect patch set is stored in the ROM 12. The preset effect patch set is read out, and the preset effect patch set is copied as a song effect patch set to a temporary location in the RAM 13 (S33), and the process proceeds to S34.
[0026]
When the copying to the temporary storage of the RAM 13 is completed, a process of displaying a confirmation screen as to whether new song data may be created on the screen of the display 16 is executed (S34). For example, a message such as “SONG NEW [ENTER] Are you sure?” May be displayed on the screen of the display 16 to indicate that the user presses the ENTER button 33.
[0027]
When the confirmation screen is displayed on the display unit 16, it is confirmed whether or not the ENTER button 33 has been pressed (S35). If the ENTER button 33 has not been pressed (S35: No), the process of creating new song data is terminated. It is checked whether the EXIT button 32 has been pressed (S38). As a result of the confirmation in S38, if the EXIT button 32 is not pressed (S38: No), it means that neither the ENTER button 33 nor the EXIT button 32 has been operated, so the flow returns to the processing of S35, and the processing of S35 and S38 is performed. Execute repeatedly until either button is operated.
[0028]
When the ENTER button 33 is operated (S35: Yes), an area for storing new song data is secured in the removable medium 14, and default values of data and parameters excluding digital audio data and a song effect patch set are set. Then, the song effect patch set temporarily recorded is copied to the song effect patch set of the new song data (S37), and the process proceeds to S40.
[0029]
On the other hand, when the EXIT button 32 is operated (S38: Yes), a process of displaying a display for canceling the creation of new song data on the screen of the display 16 for a certain period of time is executed (S39), and the process proceeds to S40. The cancel screen may display, for example, "Canceled!" Or the like to notify the user that the process of creating new song data is to be ended.
[0030]
In the process of S40, since the process of creating new song data has been completed, an instruction is given to display the basic play screen on the screen of the display 16, and the present processing routine ends.
[0031]
FIG. 4 shows a state where the song effect patch set of the current song data is copied to the song effect patch set of the new song data. As shown in FIG. 4, current song data (SONG DATA 01) includes digital audio data 1 (AUDIO DATA 1), a song effect patch set (PATCH DATA) including a plurality of song effect patches, and other various parameters (not shown). It is composed of data and the like. When the creation of the new song data (SONG DATA 02) is started, an area for digital audio data 2 (AUDIO DATA 2) is secured, and the state that the song effect patch set is copied from the current song data to the new song data is shown. Te The copied song effect patch set is a set of “S01 to S50” as the song effect patch. However, the song effect patch alone may be copied depending on the setting. The parameters may be copied together, or only various data and parameters may be copied.
[0032]
As described above, in the digital recorder, when the creation of new song data is started by operating the NEW button 31, if the current song data exists, the song effect patch set of the current song data is deleted. Copied as a song effect patch set for new song data. Also, as the current song data, the user can listen to the reproduction based on each song data and then select the song data to which an effect according to the preference is given. In other words, the song effect patch edited to your liking in the process of creating the previous song data is inherited as it is by the next song data to be created. Will be customized. Therefore, a song effect patch according to the preference can be easily created. If the current song data does not exist, the preset effect patch set is copied as the new song data's song effect patch set, eliminating the need to select a new song effect patch set and creating a song effect patch. Can be reduced.
[0033]
The created song data is stored in the removable medium 14 as a set of digital audio data and song management data. Therefore, when the created song data is read, reproducible reproduction is facilitated. It can also prevent accidental rewriting of song effect patches in the song management data, and eliminates the need to record desired effect patches in user effect patches as in the past. Thus, the correspondence between a predetermined song and a song effect patch is ensured.
[0034]
In the flowchart, the inheritance means described in claim 1 corresponds to the processing of S32 and S37, and the storage means described in claim 1 corresponds to the removable medium 14.
[0035]
As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily inferred.
[0036]
For example, in the above embodiment, when creating new song data, the song effect patch set to be copied is replaced with the song effect patch set of the previously selected song data or the song data of the song data arbitrarily selected by the user. Although the effect patch set is selected, the latest song data may be automatically determined based on a time stamp or the like, and the song effect patch set of the song data may be selected.
