[Industrial Application Field] The present invention relates to an automatic score transcription device that automatically displays music played on a keyboard on a musical staff. (Prior Art) Electronic musical instruments have been proposed that have a so-called automatic music transcription function that displays musical scores that have recently been played on a keyboard. In general, there are many cases in which a musical score output is desired, and the above-mentioned device is extremely convenient because it can produce a musical score corresponding to the performance simply by playing on the keyboard. [Problems to be Solved by the Invention] By the way, when configuring the electronic musical instrument having the above-mentioned automatic score transcription function, it is relatively easy to input only musical notes, but it is necessary to input vertical lines and various symbols used in musical scores. If you try to enter it, it will result in a very complicated configuration. This is because, for example, when looking at vertical lines, the position of the vertical line changes depending on the beat of the song, and in order to automatically input this vertical line, a complicated configuration such as detecting the beat is required. Become. Therefore, there was a problem that the device became expensive. This invention has been made in view of the above-mentioned points, and simplifies the configuration by displaying only musical notes in real time, and displaying vertical lines and symbols used in musical scores by manual input while displaying the notes in steps. The purpose of the present invention is to provide an automatic music transcription device that is easy to use and inexpensive. [Means for Solving the Problem] That is, according to the present invention, key information indicating the pitch and note length information (note information) indicating the note length generated in connection with a key press on a keyboard can be skipped over an address. By sequentially specifying the addresses of the storage means, the notes are sequentially displayed on the display means based on the storage information of the storage means, and the vertical lines or symbols necessary for the musical score are indicated by referring to the display. and editing means for manually inputting information into the skipped address of the storage means. [Operation] While the storage contents of the storage means are incremented and musical notes are displayed by the display means, vertical lines or symbols used in musical scores are input by hand at necessary locations to be stored in the skipped addresses of the storage means. [Example] The present invention will be described in detail below with reference to the accompanying drawings. The figure is a block diagram showing an embodiment of an electronic musical instrument having an automatic score transcription device according to the present invention. keyboard 1
In response to a key press on the keyboard 1, generates key information (key code) KC indicating the pressed key and a key-on signal KON indicating whether the key corresponding to the key code KC is pressed. For example, the key code KC includes the 3-bit octave codes B 3 , B 2 , B 1 representing the octave range and the 4-bit note code representing the 12 note names within one octave, as shown in Table 1.
This is a 7-bit binary coded signal consisting of N 4 , N 3 , N 2 , and N 1 .

As explained above, according to the present invention, the notes played on the keyboard are displayed in real time, and the symbols used in the score, such as vertical lines, other dynamic symbols, and speed symbols, are memorized by manual input after the performance is finished, making it very easy to use. A simple configuration makes it possible to create musical scores, and the device is also very inexpensive. Further, since a blank is provided between the note rest information and the next note information, there is no need to organize the stored information when manually inputting vertical line information etc. later.
