Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic performance device that selects music data corresponding to a desired music piece from music data for a plurality of songs and performs automatic performance based on the selected music data.

Conventionally, song data for multiple songs was stored in memory.
2. Description of the Related Art Automatic performance apparatuses are well known in which music data is selected by turning on a selection switch corresponding to a desired music piece, and automatic performance is performed based on the music data.

However, such conventional automatic performance devices cannot reproduce a desired song unless the relationship between the stored song data for a plurality of songs and the selection switch for selecting this song data is memorized.

In addition, if a read-only memory IJ (ROM) that stores multiple fractions of song data is removably attached to an electronic musical instrument, or an external recording means (for example, magnetic tape) is used, a random access memory (RAM) built into the electronic musical instrument may be used. When transferring song data for multiple K songs, the correspondence between selection switches and song names cannot be memorized, and it is necessary to prepare a table showing the correspondence between C song names and selection switches. .

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an automatic performance device that can easily select a song data corresponding to a desired song.

Therefore, the present invention provides data input means for inputting song selection data, compares this song selection data with data stored in a data storage means that stores at least song data for a plurality of songs, and selects data corresponding to the song selection data. Automatic performance is performed by searching for the starting address of the music data and sequentially reading out the music data from the searched starting address of the music data.

The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of an automatic performance apparatus according to the present invention. In FIG. 1, a keyboard 1 is used not only for normal keyboard performance but also as a data input means for selecting a song. Add to formation circuit 2 and register 3.

The musical tone forming circuit 2 forms a musical tone signal corresponding to the key pressed on the keyboard 1 based on the added key information, and applies this musical tone signal to the speaker 5 via the amplifier 4. From this K, the speaker 5 produces a sound corresponding to the pressed key on the keyboard 1.

In addition, when using the data as a manual means for selecting the first song on the keyboard, play an appropriate phrase of the song to be selected on the keyboard 1, and store the key information (pitch data) in the register 3. .

The phonological switch 6 is another data input means for selecting a song, and by turning on an appropriate switch according to the song title or lyrics of the song to be selected, character data corresponding to the song title or lyrics is input, and the distaff is selected. to be memorized.

Microphone 8. The voice detector 9 and the pitch detector 10 are further data input means for selecting a song.
When an audio signal indicating the song title, lyrics, or melody of the song to be selected is applied to the audio detector 9 and pitch detector 10, the audio detector 9 detects the song title or lyrics from the input audio signal. Character data corresponding to a song title or lyrics is stored in a register IIK, and a pitch detector 10 detects a melody from an input audio signal, and pitch data corresponding to the detected melody is stored in a register 12.

On the other hand, the data memory 13 stores song data (pitch data, note length data), song title data, and lyrics data (character data) for a plurality of songs, as shown in FIG. This data memory 13 may be either ROM or RAM.
In the case of ROM, it is a ROM that stores the above data for multiple songs.
A plurality of ROM'i are prepared, and these ROM'i are detachably attached to the automatic performance device, and in the case of a RAM, data of a plurality of oils are appropriately stored in the RAM from a magnetic card/tape, punch card, bar code, etc.

The data memory 13 also stores data indicating a change in the number of songs at the beginning of each piece of music data.

Here, a case will be described in which a desired song is selected and the song is automatically played.

First, using any one of the data input means described above, music selection data such as character data corresponding to the song title or lyrics of the song to be selected or pitch data of the song to be selected is transferred to the shift register 3. 7, 11.12
Store it in one of the following.

Note that when the lyrics and the audio signal indicated by melody (Y) are added through the microphone 8, the character data and pitch data are simultaneously stored in the registers 11 and 12, respectively.

Next, the search start switch 14 is turned on.

When switch 14 is turned on, search address counter 1
5 becomes operational and counts high-speed clock pulses φ.

This count value is output as an address signal of the data memory 13. Note that the switch 14 is a non-locking switch, and the search address counter 15 is a non-locking switch.
It outputs an address signal indicating all addresses of 3, and stops counting when a carry-out signal is output.

The address signal from search address counter 15 is applied to data memory 13 and head address detector 16. The data memory 13 stores song data, song title data, lyrics data, etc. corresponding to the first song based on the input address signal.
Data is sequentially read out in the order of song data, song title data, lyrics data, etc. corresponding to the second song (see Fig. 2).The data read out from the data memory 13 is read out from the search circuit 17, respectively. It is added to the musical tone forming circuit 18 and the note length counter 19. Note that the musical tone forming circuit 18 is inoperable when a song is selected.

The search circuit 17 compares the song selection data stored in advance in any of the registers 3, 7, 11.12 and the data sequentially inputted from the data memory 13, and outputs a match signal mctt when these data match. . Further, when the output data from the data memory 13 is data indicating a change in the number of songs (the beginning of each song data), the search circuit 17 sends a signal 8
Output T.

The coincidence signal Hall is output to the display 20 and the head address detector 16, and the signal BT is output to the head address detector 16.

When the match signal EQ1 is applied, the display 20 lights up a lamp to indicate the success of the search.

The start address detector 16 detects the start address of the song data corresponding to the song to be selected, and every time the signal ST is inputted from the search circuit 17, this signal ST
When a new trap address signal is input from the trap search at I/counter 15 and a match signal 11CQI is input from the search circuit 17, the input address signal is searched at the beginning of the song data corresponding to the song to be selected. It is output to the music progress address counter 21 as an address.

When the selection of the desired song is completed and the selected song is to be played back, the song start switch 22 is turned on.

When the song start switch 22 is turned on, the song progression address counter 21 becomes operational. First, the count value of the counter is set based on the address signal input from the head address detector 16, and this count value is stored in the data memory 13. It is output to the data memory 13 as an address signal. The data memory 13 reads out the leading data (pitch data and note length data) of the song data based on this address signal.

' The musical tone forming circuit 18 forms a musical tone signal based on the pitch data read out from the data memory 13, and applies this musical tone signal to the speaker 5 via the amplifier 4.
Make a sound corresponding to the pitch data.

The note length counter 19 counts the tempo clock TOLg applied from the tempo oscillator 23, and when this counted value matches the pitch data read from the data memory 13, outputs a note length match signal EQ2 to the music progression address counter 21. At the same time, the 1 count value is reset.

The music progression address counter 21 counts up in response to the note length match signal KQ2 applied from the note length counter 19, adds the counted up count value to the data memory 13 as a new address signal, and adds the second pitch data and note length to the data memory 13 as a new address signal. Read long data 2.

Automatically play the selected song by repeating the above operations.
I can do that.

As explained above, according to the present invention, a desired song can be selected by inputting at least one of the pitch sequence, song title, or lyrics data of the desired song using a keyboard, a phonological switch, a microphone, etc. - can. That is, a desired song can be selected simply by recognizing what songs are stored in the data memory.

The pitch sequence, song title, or lyrics data need only be long enough to select a desired song from among the plurality of songs stored in the data memory.
