In step S35, conversion is performed for displaying the selected music data on an ordinary musical score, and in step S36, the screen of the display 20f is displayed.
A standard score is displayed on the left half (or upper half) of the screen, and a special score (music score for music box) is displayed on the right half (or lower half) of the screen, and the process proceeds to step S37. It is determined whether or not there is an instruction as to whether or not the printed special musical score is to be printed out. If there is no instruction to print out, the process directly proceeds to step S39, and if there is an instruction to print out, step S38.
In step S39, the special score is printed out by the printer 20q in a special format suitable for the score S.
Proceed to. Note that, in detail, in step S38, the process of converting the data displayed on the screen into the data for printing is performed before printing out. In step S39, it is determined whether or not there is an end instruction from the user. If not, the process returns to step S31, and if completed, the process ends.

In the format conversion process of FIG. 8, in step S41, the data for the score insertion direction arrow display a, the data for the musical score display b, the data for the staff notation c, the treble clef display d and the bass clef display e are displayed. Create data for.
Next, in step S42, the length L1 (see FIG. 10) on the score S corresponding to the quarter note is preset in mm,
In step S43, the display position P (see FIG. 10) in the longitudinal direction of the first musical score on the score S is set in mm. This value is set by reading preset data.

Next, in step S44, the note number n is set to "0" (initial value), the number n is incremented in step S401, and the determination process in step S402 is performed. Just repeat. In step S45, the nth note is detected from the music data, the vertical position of the note display is set by the pitch information (pitch) of the nth note at the designated P position, and the note ball f is set at that position. Is displayed and the mode of the note ball f and the bar display g is displayed by the note length information of the nth note. next,
In step S46, the interval between the nth note and the n + 1th note (n + 1th timing data (duration))
In step S47, it is determined whether or not the interval between the nth note and the n + 1th note is less than or equal to a predetermined value close to zero (for example, 1 / 128th note). In S48, the same position (current P) in the longitudinal direction of the immediately preceding note (nth) is designated as the position to be displayed next, and the process proceeds to step S401. If the interval is not less than the predetermined value, the interval between the immediately preceding note (nth number) and the next note (n + 1th number) is detected in step S49, and the length P ₁ corresponding to this interval is added to P. The longitudinal display position (P ← P + P ₁ ) of the selected score S is designated as the next display position, and the process proceeds to step S401.

In the processes of steps S47 to S49, slight deviations are judged to be chords or heavy tones and displayed at the same position in the longitudinal direction (step S48), and otherwise, at intervals according to the note length of the preceding and following notes. This is processing for displaying (step S49). That is, the standard MIDI file format is a format that enables the storage device to store or transmit / receive either step input or real-time input. Therefore, the musical tone information that is input in real time with an electronic string instrument or an electronic keyboard instrument includes those that were played with the intention of being a heavy note (or chord), but each note information is not necessarily a heavy note. "Pitch", "Pitch", "Note length" ... The key press of each finger is not always simultaneous key-on, and in many cases is slightly shifted. If these pieces of music data are transmitted from the server to the user as they are to be converted into musical scores, a list of small notes will result. And not only the score creation process becomes complicated, but the score becomes very difficult to understand. In the present invention, the musical score preparation for the music box is intended, but the musical score can be viewed as an ordinary musical score, and the music can be understood by looking at the musical score. In that case, even if each of the heavy tones is stored with a slight time difference, it is better to describe the heavy tones as heavy tones and enable the music box to be played. This embodiment also addresses such a point.

Then, in step S401, n is incremented, and if there is the nth note in step S402, the process returns to step S45. If there is no nth note, in step S403 the total length in the longitudinal direction of the score S, that is, , The data of the display a having a length obtained by adding the length A corresponding to the blank portion h (see FIG. 10) to the position P of the last note is created, and the process is ended.

By the above format conversion processing, the music data is converted into the display data corresponding to the print elements shown in FIG. 10, and this display data is displayed in step S3 of FIG.
It is used for the display in 6 and the printout in step S38.

The printer 20q may be a printer that manually prints the score for the music box on the score S, or may be a printer that manually prints the score for the music box on a normal printing paper. In the former case, the printed score S is perforated by the perforating jig, and in the latter case, the printed sheet is temporarily fixed to the plain score S and perforated by the perforating jig. do it.

In the above embodiment, the timing data of the music data is the data representing the elapsed time from the previous event, but the absolute time (clock) from the beginning of the music is used as the event timing data. Even in the case of performing, the same processing corresponding to the above-described embodiment can be performed.

In the above embodiments, the case where the music data is distributed via the network has been described. However, a conversion program is prepared in the personal computer so that the music data can be stored in, for example, a CD-ROM, a memory stick, a smart media, an FD or the like. The recording medium may be supplied to a personal computer or the like, and the musical score for a music box may be displayed or printed out from this music data. Further, the conversion program may be supplied by each of the above recording media.
