DETAILED DESCRIPTION OF THE INVENTION
A karaoke apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of the karaoke apparatus.
[0012]
This karaoke apparatus is connected to a MIDI keyboard 31 as performance means via a MIDI interface 18. When a user plays the MIDI keyboard 31, MIDI data is generated, and this MIDI data is input to the karaoke apparatus main body via the MIDI interface 18. In the karaoke apparatus main body, the CPU 10 transmits the MIDI data to the built-in tone generator 19 to form a musical tone signal, and detects a specific pattern performance based on the MIDI data. The performance of a specific pattern is a glissando or continuous on of adjacent keys. When detecting the performance of the specific pattern, the CPU 10 executes control operations such as transposition (key change) and pause / restart of the karaoke performance.
[0013]
The sound source device 19 is in charge of both karaoke performance and sound generation by the MIDI keyboard 31, but has a sound generation channel that simultaneously generates 64 sounds, and even during karaoke performance, the MIDI channel is used by using an empty channel. A musical sound signal can be formed by playing the keyboard 31.
[0014]
In addition to the karaoke performance based on the music data, this karaoke apparatus can reproduce information data and disclose information such as operation guides and event guidance for the karaoke apparatus to the user. This information data is described in the same format as the music data, and is stored in the HDD 15 like the music data.
[0015]
In FIG. 1, a CPU 10 for controlling the operation of the entire apparatus includes a ROM 11, a RAM 12, an HDD 15, a communication control unit 16, a remote control receiving unit 17, a display panel 13, a panel switch 14, a sound source device 19, and an audio decoder 21 via a bus. , DSP 22, character display unit 23, LD changer 24, display control unit 25, and MIDI interface 18 are connected.
[0016]
The ROM 11 stores system programs, loaders, application programs, font data, and the like. The system program is a program for controlling the basic operation of the apparatus and the operation of peripheral devices. The loader is a program for downloading music data and the like from the center. The application program includes a peripheral device control program, a sequence program, and the like. The sequence program includes a main sequence program, a musical tone sequence program, a character sequence program, a voice sequence program, and a DSP control sequence program. At the time of karaoke performance, each sequence program is processed in parallel by the CPU 10, and each track of the music data is read out based on each program, and processing such as generation of musical sound and reproduction of video is executed. The font data is used for displaying lyrics and song titles, and fonts of a plurality of types of characters such as Mincho and Gothic are stored. The RAM 12 is set with a work area such as an execution data storage area for reading and storing data of the currently executed karaoke song. The execution data storage area is an area for reading music data and information data from the HDD 15 when executing karaoke performance or reproduction of information data.
[0017]
A music data file and an information data file are set in the HDD 15. The music data file stores about 10,000 music data. A plurality of information data is also stored in the information data file. The music data is composed of a musical tone track, a character track, a voice track, a DSP control track, and the like, which are read in parallel by the musical tone sequence program, the character sequence program, the voice sequence program, and the DSP control sequence program, respectively. The read data is input to the tone generator 19, the character display unit 23, the audio decoder 21, the DSP 22, etc., and is output as a musical sound or video. The information data has the same structure as the music data, and is read out in parallel by a musical tone sequence program, a character sequence program, a voice sequence program, and a DSP control sequence program, and the sound source device 19, the character display unit 23, the voice. It is output as a musical sound or video by the decoder 21, DSP 22, or the like. The information data includes, for example, device operation guides and event guides. The operation guide displays the operation method as a video and announces audio data. In addition, the event guide displays an overview of the event as a video and also announces or plays a part of the song to be played as audio.
[0018]
The communication control unit 16 communicates with the center via a communication line such as an ISDN line, and downloads music data, information data, and the like from the center. The downloaded data is written to the HDD 15.
[0019]
The remote control receiving unit 17 is a circuit that receives an infrared signal transmitted from the remote control 30 and restores data. The remote controller 30 includes a music selection switch, a numeric keypad, and the like, and transmits an infrared signal when these switches are turned on.

The panel switch 14 is provided in the front operation unit of the karaoke apparatus, and includes a song code input switch, a transpose switch, and the like.
[0020]
The tone generator 19 forms a tone signal based on data read from the tone track of the music data. A MIDI keyboard 31 is connected to the MIDI interface 18. The MIDI keyboard 31 is a five-octave (C1-C6) 61-key keyboard, and generates MIDI data corresponding to the performance. The generated MIDI data is input to the CPU 10 via the MIDI interface 18. Since the CPU 10 always transmits the input MIDI data to the tone generator 19, the musical tone is output from the speaker of the karaoke device whenever the user plays the MIDI keyboard 31. Further, the CPU 10 monitors the performance pattern of the MIDI keyboard 31 using MIDI data. When a performance of a specific pattern (MIDI data string) is input, the karaoke performance is transposed (key change) or temporarily depending on the pattern. An operation for controlling the function of the apparatus such as stop / restart is executed.
[0021]
The audio decoder 21 receives audio data that is ADPCM data and decodes it into an audio signal. Digital musical tone signals and audio signals output from the tone generator 19 and the audio decoder 21 are input to the DSP 22. A microphone 27 is connected to the DSP 22. The signal of the microphone 27 is converted into a digital signal at the input unit. The DSP 22 gives effects such as reverberation and echo to the musical sound signal and the voice signal input from the sound source device 19, the voice decoder 21 and the microphone 27. The type and degree of the effect provided by the DSP 22 is controlled based on the DSP control data written in the DSP control track of the music data. The musical sound signal and the audio signal to which the effect is applied are mixed and converted into an analog signal, which is then output to the amplifier / speaker 26. The amplifier / speaker 26 amplifies this signal and then emits the sound.
[0022]
The character display unit 23 generates a character pattern such as a song name and lyrics based on event data input from the lyrics track of the song data. The LD changer 24 incorporates about five laser disks and can reproduce 120 types of background images. One background image is selected from the input chapter numbers. The character pattern output from the character display unit 23 and the video data output from the LD changer 24 are input to the display control unit 25. The display control unit 25 synthesizes these data with superimpose and displays them on the monitor 28.
[0023]
The performance of the specific pattern will be described with reference to FIG. This figure shows a pattern for instructing a pause of transpose and karaoke performance. FIG. 2A is a diagram showing a transposition method. FIG. 5B is a diagram showing a glissando method for temporarily stopping karaoke performance. First, in order to enter a control mode for performing this transpose or pause, the key of the lowest sound (C1) is turned on. Then, turn on the key of (2) while turning on the key of (1) in the same figure (A), or turn on the key of (3) while turning on the key of (2), or (1) Turn on the two white keys in the order of lower (lower side) → upper (higher side), such as turning on the key of ▲ 3 while turning on the key of ▼. Can be transposed. On the other hand, turn on the key of (2) while turning on the key of (3) in the figure, or turn on the key of (1) while turning on the key of (2), or the key of (3) The karaoke performance can be transposed down one semitone by turning on both of the two white keys in the order of up to down, such as turning on the key (1) while turning on. Also, if the glissando is played while the lowest key is turned on (in the control mode), the karaoke performance is paused. After that, if any key (any key) is turned on, the karaoke performance is resumed. Here, the glissando is defined as an “operation for sequentially turning on and off three or more adjacent keys at intervals of 0.5 seconds or less”. And “turning on / off in order” means turning off the key that was turned on first and then turning on the next key. Thus, in this embodiment, the karaoke performance operation can be controlled with a key-on pattern that can be easily performed by anyone without specifying a key to be operated.
[0024]
The operation when MIDI data is received from the MIDI keyboard 31 will be described below with reference to the flowcharts of FIGS. This figure shows the operation of receiving a MIDI event during karaoke performance, judging a specific pattern, and controlling the pause / restart of transposition and karaoke performance.
When MIDI event data is received from the MIDI keyboard 31 during execution of the karaoke performance operation, this operation is executed. If the received MIDI event data is key-on event data, the operation proceeds to the operation of s10 or less by the determination of s1. On the other hand, if the received MIDI event data is key-off event data, the process proceeds to the operation from s41 onward in the determination of s40. If the received MIDI event data is event data other than the key-on / key-off event, processing corresponding to the MIDI event data is executed (s46), and the process returns.
[0025]
When the key-on event data is received, first, the tone generation process corresponding to the key-on is executed (s10). In the sound generation process, a sound channel that is not used for karaoke performance is searched for among the sound channels of the tone generator 19 and the tone of this musical tone is assigned to the sound channel, and tone data and pitch are assigned to the sound channel. This is a process of transmitting pronunciation data including data. The tone generation channel of the tone generator 19 forms a musical tone signal based on these data.
[0026]
Next, it is determined whether the karaoke performance is currently paused (s11). If the karaoke performance is paused, the karaoke performance is restarted regardless of which key is turned on (s12), and the process proceeds to s13. If the karaoke performance is currently being executed, the process proceeds to s13.
[0027]
In s13, it is determined whether or not the currently-on key is the lowest tone key (C1 key: the leftmost key of the keyboard). If it is the lowest tone key, there is a possibility of control operations such as the above-mentioned transpose and pause of performance (although there is a possibility of normal performance), the control mode flag Fe is set (s14), and the timer T, the key number counter N is reset (s15), and the process returns. These timer T and key number counter N are set for detecting the glissando performance.
[0028]
On the other hand, if it is not the lowest sound key, it is determined whether it is another white key or a black key (s16). In the case of a black key, it is a normal performance and there is no possibility of a control operation, so the process returns directly.
[0029]
In the case of a white key, it is determined whether or not the control mode flag Fe is currently turned on (s17). If the control mode flag Fe is not set, this white key key-on is a normal performance. Since it is not a control operation, the process directly returns from s17. If the control mode flag Fe is set in s17, the process proceeds from s17 to s18 because the key-on of the white key may be a control operation. In s18, first, the state of the timer T is confirmed. It is determined whether the count value of the timer T is greater than 0 (that is, the timer has started) and the count value is 0.5 seconds or less. If the lowest white key is turned on and the control mode flag Fe is set and the first white key is turned on, the timer T is not started. In this case, the process proceeds to s19 based on the determination in s18. After s19, the key number of the white key keyed on this time is stored (s19), 1 is added to the key number counter N to start the timer T (s20), and the transpose flag Ft is set (s21). The timer T detects the time interval between successive key-ons, and the key number counter N counts the number of consecutive key-ons. The glissando is detected according to these contents. The transpose flag is a flag for detecting a transpose operation when Ft is a key-on with two overlapping keys. When the white key is first turned on in the control mode (the lowest tone key is on), it is still unknown whether the performance is transpose or pause (glissando), so the timer T and the transpose flag Ft Enable both and return.
[0030]
Here, the operation when key-off event data is input will be described with reference to FIG. When the key-off event data is input, first, the corresponding sound is silenced (s41). Next, it is determined whether the input key is a lowest sound key or a memory key (s42, s43). The storage key is a key whose key number is stored in s19 or s27. When the lowest tone key is turned off, the control mode is lost, so both the control mode flag Fe and the transpose flag Ft are reset (s44), the timer T is stopped (s45), and the process returns. On the other hand, when the storage key is turned off, the transpose flag Ft is reset because there is no possibility of a transpose operation in which two keys (except the lowest sound key) are turned on redundantly (s46) and the return. To do. However, even in this case, since there is a possibility of a pause operation (glissando), the timer T continues counting.
[0031]
Returning to FIG. 3, when the white key is first turned on in the control mode and there is a next key-on without the key being turned off, if this key-on is a white key, the process proceeds from s16 to s17, and the key-off process is performed. Since the transpose flag Ft remains set, the process proceeds from s17 to s31. In s31, the key number of the key keyed on this time is compared with the key number of the storage key (the key key-on previously stored in s19). If the current key is higher than the stored key as a result of the comparison, the karaoke performance is transposed by +1 semitone (s32). Thereafter, all karaoke performances are performed one semitone higher. In this process, when the CPU 10 sends the performance data read from the music data to the tone generator 19, 1 may be added to the pitch data (value indicating the number of semitones) in the performance data. On the other hand, if the current key is lower than the comparison result storage key, the karaoke performance is transposed by -1 semitone (s33). Thereafter, all karaoke performances are performed one semitone lower.
[0032]
On the other hand, when the white key once turned on is keyed off and then the next white key is keyed on, the transpose flag Ft is reset as described above. Determine the value of. Since T> 0 since the timer T is started by the previous white key being turned on, if T> 0.5, it is determined that the interval is too wide and the glissando is not played. Then, since there is a possibility of starting a new control operation, the process proceeds to s19. If 0.5 ≧ T> 0, there is a possibility of glissando, so the process proceeds to s22. In s22, the timer T is stopped and reset. Then, it is determined whether the key turned on this time is a white key next to the storage key (s23). This determination is made based on the key number. If it is a neighboring key, 1 is added to the key number counter N (s25). As a result of this addition, if the key number counter N is 3 or more, that is, if the number of keys continuously turned on or off is 3 or more, the karaoke performance is stopped halfway because it is an operation for temporarily stopping the glissando, that is, karaoke performance. (S29) and return. If the key number counter N is 2 in s26, the current key number is stored (s27), the timer T is restarted (s28), and the process returns. If the key turned on in s23 is not the adjacent key, N is cleared and the process returns (s24).
[0033]
FIG. 5 is a diagram showing another embodiment of the transpose process surrounded by a broken-line square in FIG. In the embodiment of FIG. 3, the second key is transposed by one semitone up or down depending on whether it is above or below the first key (memory key). Then, the karaoke performance is transposed by the difference depending on how far the second key is turned on from the memory key. That is, the key number of the current key and the storage key is subtracted in s50, and the karaoke performance is transposed by the difference (s51). If the difference is positive, you can raise the pitch, and if the difference is negative, you can lower the pitch. In this operation, since the desired key can be transposed at one time, the transpose flag Ft is reset after one process (s52). In this case, since the transpose in semitone units cannot be performed only with the white key, the black key may be used as the second key to be turned on.
[0034]
In this process, the amount of transposition changes depending on the interval between the white key that is turned on first and the white key that is turned on second, so it is not a sensuous pattern operation, but the key to be operated is specified. It can be said that there is no sense operation.
[0035]
In the above embodiment, the key for entering the control mode is the lowest sound key. However, the present invention is not limited to this, and a combination of a plurality of keys may be used. Further, the control target can be applied not only to karaoke performance, but also to switching or temporary stop of information data reproduced between karaoke performance songs.
[0036]
Further, in this embodiment, the karaoke performance is controlled by the performance operation of the MIDI keyboard, but the tone generation function itself such as the tone color of the tone generated by the performance of the MIDI keyboard may be controlled. In this case, if you set a phrase for the performance location that you want to change in the song that you want to play as a specific pattern, and change the setting when you play that phrase, you can perform a special operation to change the setting. Even if you don't have to do it, you can change the settings with the performance itself. The specific pattern can be set by setting the karaoke apparatus in the setting mode with the remote controller 30 or the like and storing the MIDI data string input from the MIDI keyboard 31 in this mode as the specific pattern.
[0037]
The switching of timbres by playing a specific pattern of the keyboard can be applied not only to a karaoke apparatus but also to an electronic musical instrument equipped with a keyboard. In this case, switching of accompaniment patterns and effects in addition to the timbre is also possible. This can be applied to, for example.
[0038]
【The invention's effect】
According to the present invention, since the performance of the karaoke apparatus can be easily controlled using the performance means connected to the apparatus, the operation becomes easy and the performance means can be performed. Even if a player does not bother to operate with a remote control, it can be operated as it is with the performance means.
