Description

DETAILED DESCRIPTION OF THE INVENTION The present invention determines the length of one bar based on a set tempo, encodes the pitch and length of the notes played on the keyboard, and sequentially imports the codes into a storage means. Furthermore, the present invention relates to a heavy musical instrument having a function of editing the encoded pitch/length data.

Conventionally, the performance information from the snoring board was encoded and stored (A. In Shigeko instruments, the encoded pitch and length information can be edited according to the player's requests, after editing, It often happens that the time signature in the bar is not consistent with the time signature.In that case, the pitch and length data of the note and length are converted to the r9T fixed chord, and the position of the measure and the scale are changed. 6
The size of the notes is checked using a means of visually displaying them, a means of reproducing sounds that are pronounced sequentially, etc. However, the longer the piece is, the more time-consuming work it becomes. becomes.

Therefore, we tried to match the time signature within one measure over all measures.
By displaying the recognition of uncoordinated measures and automatically instructing the performer on the position of the measures that are inconsistent with the time signature, it saves time and effort during editing operations. This is what we are trying to eliminate.

Hereinafter, the present invention will be explained in detail with reference to FIG.

The overall configuration M of the embodiment of the present invention is placed in ff1ll'Z.

When the mode setting switch 19 reverses the actual memory mode, the pressed key on the snoring board 1 is coded to a predetermined pitch information by the key encoder 2, the musical tone synthesizer 3, and the amplification device 4. , is output as sound through the speaker 5, and passes through the input output board 8 (hereinafter abbreviated as I10 board) to the central processing unit f! ! 1 ≠ position 9 (hereinafter OPN'
). Furthermore, when pressing a key on the keyboard, the on/off state of the key is detected by the rising/falling part 6, and the time in between is determined by the counter 7 and the tempo clock generator 16, and is encoded. At the same time as the pitch information, the sound length information is passed through ■108 and reaches OL) V9. 0
The Pv9 sequentially stores encoded pitch and length data in a random access memory 10 (hereinafter referred to as R) according to the keyboard performance.
(abbreviated as AM). The pitch and length data stored in the RAM 10 are sequentially read out at a speed specified by the tempo clock generated by the tempo clock generator 16, unless the playback mode is selected with the mode setting switch 19, for example. , 11011, one is sent to the musical tone synthesis section 8 and sequentially output as sound, and the other is sent to the display conversion section 12.
For example, the cathode
Display example 1 for tubes (abbreviated as 01.T), etc.
8, they are sequentially displayed in the form of musical scores, for example.

An example of this display is shown in FIG. In this example, there is a music score area for two lines on one screen, with each line containing four measures.)
This shows an operation in which the signals are sequentially outputted from tAMIO according to the read clock of the tempo clock generator 16, converted into a predetermined display code by the display converter 12, and then sequentially displayed as a musical score on the screen. At this time, the player is informed of the currently specified data in the musical score data in RAM10 using the cursor 21. Furthermore, when the length of a song exceeds two lines, the display of musical score data on the old screen is cleared and the score data is sequentially displayed on the new screen in the same way.

Now, suppose that a certain song has been input, and the performer performs editing processing such as correction and arrangement.

This operation is performed by setting the mode setting switch 19 to an editing mode and using the editing operation keys 18. After that, if you select the time signature consistency check mode (error check) with the mode setting switch 19, the fourth
The functions shown in the figure will start. That is, in this example) the format of the musical score data stored in LAM 10 is
As shown in Figure 8, the bar lines, notes, and rest data are arranged in a manner that corresponds to the order of the score, so the notes are played every measure from the first measure to the last measure. The total length data is taken and it is checked whether it matches the time signature set by the time signature select switch 17. If they match, the process moves on to the next measure, but if they do not match, the contents of the error count table 14 for counting the total number are incremented by 1, and the bar line data at the beginning of that measure is )) Manipulate some bits of the 31st foot to leave the sign and move on to the next process. When this process has been completed for all measures, the total number of errors in the error count table 14 is reported on a display device such as a 7-segment display 15. Regarding this, even if no other display device is installed,
Error count table 14 is built into 0PV9 and OR
It can also be configured to be displayed on the display section @18 such as T. Immediately after the error count value is notified, the first data of the bar in which the error occurred is indicated, so it is displayed as shown in FIG. Then, when the error is corrected, the cursor will point to the next error and move on to the next error, so if the performer performs the editing process one by one, he or she can correct the time signature mismatch. You can edit the song to a song without. Although the case here is that data encoding processing is performed on unmatched bar lines, it is also possible to temporarily store and notify the position information of the bars in a similar manner.

With this configuration, when a performer inputs a piece of music and arranges it as desired, an error such as a time signature mismatch may occur. Not only that, but also the self l1 at the position of the measure with the error.
Since the instructions are sequentially subtracted by -1 in a lh-like manner, it is possible to greatly reduce the amount of time and effort required for the performer, except for the editing.
