[0013]

In the performance instructing device of the present invention, at least one part of the music information of a plurality of parts supplied by the music information supplying means is designated as a guide part (guide part designating means). The performance instruction means gives a performance instruction for this guide part. Performance instructions, for example, according to the progress of the song,
This is performed by outputting a signal (display, voice, etc.) instructing the pronunciation of a certain musical sound at the timing at which the certain musical sound should be generated. In the case of a keyboard instrument, there is a system in which a lamp corresponding to each key is provided and a lamp corresponding to a key of the pitch is turned on at a sounding timing of a certain musical sound. As a result, by designating the guide part by the guide part designating means, it is possible to instruct the performance of an arbitrary part regardless of the music data.

In this performance instructing device, the music information supplying means can also supply music information for which a guide part is designated in advance. When the music information in which the guide part is designated in advance is supplied, the performance instructing means operates based on the designation of the guide part to give a performance instruction. The guide part designation means becomes effective when music information in which no guide part is designated is supplied in advance, and in this case, the performance instruction is executed based on the guide part designated by the guide part designation means.

In the electronic musical instrument of the present invention, the music information supply means supplies the time-series performance data group (music information) of a plurality of parts, and the performance means generates the performance data by the operation of the performer. At least one part of the music information is designated as a guide part by the guide part designation means. The performance data of the guide part supplied in time series is compared with the performance data input from the performance means, and the input of the music information to the tone signal synthesis means is controlled based on the comparison result. The musical tone signal synthesizing means synthesizes musical tone signals based on the input performance data. This allows
It becomes possible for the performer to control the progress of parts other than the guide part in synchronization with the progress of playing the guide part.

In this electronic musical instrument, the music information supplying means can also supply music information in which the guide part is designated in advance, and when music information in which the guide part is designated in advance is supplied, The performance data of the designated guide part is compared with the performance data input from the performance means. The guide part designating means becomes effective when the music information in which the guide part is not designated is supplied in advance. Thereby, it is possible to use both the music information in which the guide part is designated in advance and the music information in which the guide part is not designated.

In the performance instruction device and the electronic musical instrument, the guide part designating means designates one or both of the right-hand part and the left-hand part of the keyboard so as to perform sound production control by performance instruction or comparison. This allows even beginners to play keyboard instruments,
It is also possible to guide both hands at the same time.

Further, in the invention of claim 7, the performance data of the parts other than the guide part are input to the musical tone signal synthesizing means to generate a musical tone, and the performance data of the guide part is instructed by the performance instructing means. The musical tone signal is synthesized when played correctly according to the instruction.
This makes it possible to perform settings such as automatically playing an arbitrary part as an accompaniment while playing an arbitrary part based on the guide.

The number of songs is stored. The music information is structured as shown in FIG. The disk 14 may be a hard disk or a floppy disk. A large number of pieces of music information are stored in the disk 14, and one of the pieces of music can be selected by operating the numerical value input switches included in the switch group 18, and the one designated by turning on the load switch can be selected. The music information of the music is stored in the music information memory 13
Loaded in. The keyboard 16 has 61 keys (C1 to C6),
76 keys (E0 to G6) or 88 keys (A-1 to C7)
Any of these may be used. The LED group 17 is composed of 61, 76 or 88 LEDs provided corresponding to each key of the keyboard 16 used.

On the operation panel 18, in addition to the numerical value input switch and the load switch, a guide mode switch for turning on / off the guide mode, a match progress mode switch for turning on / off the match progress mode, and a key pressing instruction display mode are turned on. / Key-off instruction display mode switch to turn off / off, part change switch to switch the guide part, guide track specification switch to specify the track (guide track) to be the right hand part / left part, start / stop switch to start / stop automatic performance A display etc. are provided.

The timer 19 interrupts the CPU 10 at every 96th note in accordance with the tempo of the music during automatic performance. The sound source 20 forms a musical tone signal according to data input in response to a player's key-on or automatic performance.
A sound system 21 is connected to the sound source 20.
The musical tone signal generated by the sound source 20 is input to the sound system 21. The sound system 21 amplifies this musical sound signal and outputs it from the speaker.

FIG. 3 is a view for explaining the music information stored in the music information memory 21. The music information is composed of sequence data of a plurality of tracks, and the sequence data of each track is composed of a combination of data blocks such as sound generation data, duration data and end data shown in this figure. The tone generation data is data for producing a tone signal in the automatic performance mode, and includes a key-on code, a key code, velocity and gate time. The key-on code is a code indicating that it is pronunciation data. The key code is data indicating a pitch, that is, a key number. Velocity is a code indicating the strength of key depression, that is, the loudness of pronunciation. The gate time is data indicating the sounding time (note length). The duration data is data indicating a time interval between each data block, and includes a duration code and a duration time. The duration code is data indicating that it is duration data. The duration time is data representing the interval, and is represented by the number of notes converted into 96th notes. For example, the length of an eighth note is 12. Also, the end data is data indicating the end of the music information and is composed of an end code. The music information is configured by alternately writing pronunciation data, which is event data, and duration data, which indicates an interval between the pronunciation data.

In this embodiment, 1 as data
The sequence data of a track corresponds to one part as a performance, and tracks and parts are used almost synonymously, but one part may be composed of multiple tracks, and multiple parts may be described in one track. You may do it.

FIG. 4 is a diagram for explaining various registers set in the RAM 12. 5 to 12 are flowcharts showing the operation of the electronic keyboard instrument. The operation of the electronic keyboard instrument will be described with reference to these figures.

5 to 7 show the main routine. When the power of the electronic keyboard instrument is turned on, first, the initial setting operation (n1) is executed. The initial setting operation is shown in FIG.
It is an operation such as resetting the register and the list area shown in FIG. After this, the load switch, guide mode switch, coincidence progression mode switch, key pressing instruction display mode switch, part change switch, guide track constant switch, numeric input switch, start / stop switch ON event and the presence of a key event are determined. .

When the ON event of the load switch is detected (n2), the music information designated by the song number register SGN is read out from the plurality of music information stored in the disk 14 and written in the music information memory 13. (N3). After that, the guide track designation information is read from the header portion of the music information, and it is determined whether or not the guide track is designated in the music information in advance (n4).

When the guide track is designated in advance, 0 is set in the track unset flag PP (n5), the track number 0 is written in the right-hand part register PN (0), and the left-hand part register PN (1 )
The track number 1 is written in (n6). Here, in the case of the music information in which the guide track is designated in advance,
It is assumed that the right-hand part sequence data is written in the 0th track and the left-hand part sequence data is written in the first track. On the other hand, in the case of the music information in which the guide track is not designated, the guide track unset flag PP is set to 1 (n7),
As a default value, the track number 0 is written in the guide track register TRN (0) of the right hand part, and the track number 1 is written in the guide track register TRN (1) of the left hand part.

When the guide mode switch is turned on (n8), the guide mode flag GD is set to "1".
/ 0 "is inverted (n9). As a result of inversion, GD is" 1 "
When, the following matching progress mode and key pressing instruction display mode are turned on. Furthermore, the reproduction of the key-on event data of the guide track is prohibited. It should be noted that the guide mode switch and the guide mode flag GD may be omitted when the coincidence proceeding mode and the key pressing instruction mode are independently turned on / off.

When there is an on event of the match progress mode switch (n10), the match progress mode flag CPR
Is inverted (n11). When the CPR becomes "1" as a result of the inversion, the coincidence progress mode is turned on. In the coincidence progression mode, the automatic performance proceeds when the key-on event data of the guide track and the key-on event generated when the performer plays the keyboard 16 coincide.

When there is an on event of the key pressing instruction display mode switch (n12), the key pressing instruction display mode flag IND is inverted (n13). Inversion result, IND
When the key becomes "1", the key pressing instruction display mode is turned on. In the key-depression instruction display mode, the LED 17 corresponding to each key on the keyboard 16 is turned on in response to the key-on event data of the guide track.

When there is an on event of the guide track setting switch (n14), PP is determined (n1).
5). When PP = 0, a guide track is set in advance in the music information, and therefore the guide track designation operation is not accepted and the operation proceeds to the next operation. When PP = 1, the guide track designation mode flag GTS is inverted (n
16). When GTS = 1 as a result of the inversion, the guide track designation mode is turned on.

When the part change switch is turned on (n17), the guide track designation mode flag GTS is determined (n18). When GTS = 1, the mode is the guide track designation mode, so the right hand / left hand flag LR designating the part designating the guide track is switched to right hand = 0 / left hand = 1 (n19). In the case of GTS = 0, since the mode is for specifying which of the right hand part and the left hand part is to be guided, the guide part register PRT is sequentially switched to right hand = 0, left hand = 1, both hands = 2 (n20). .

When a numerical value is input from the numerical value input switch (n21), the GTS is judged (n22), and the GTS is determined.
When = 1 (guide track designation mode), TRN (L
R) (n23). On the other hand, when GTS = 0, the input numerical value is set in the song number register SGN as the song information number (song number) (n24).

When an on-event of the start / stop switch is detected (n25), the automatic performance flag R
Invert UN (n26). As a result of this inversion, RUN =
When it becomes 1 (n27), the automatic performance start operation (n28) is executed. When RUN = 0 as a result of the inversion, the automatic performance stop processing (n29) is executed.
The automatic performance stop processing is to mute the automatic performance sound being produced at that time, clear the key code waiting key code list,
For example, the LED 17 is turned off.

When a key event is detected (n3
0), it is determined whether the event is a key-on event or a key-off event (n31). In the case of a key-on event, key-on processing such as sound generation processing is executed (n32),
The key code of the turned-on key is written in the key-depression key code table (n33). After this, the comparison process (see FIG. 12)
(See) is executed (n34). On the other hand, in the case of a key-off event, after executing a key-off process such as a mute process (n35), it is determined whether or not the key code of the turned-off key remains in the key-depression key code table (n3).
6) If it remains, erase it (n37).

After that, other processing is executed (n3
8). The other processing includes volume control processing, display switching processing, and the like.

FIG. 8 is a flowchart showing the automatic performance start process. First, at n41, the read pointers of tracks 0 to 15 are set to the heads of the corresponding storage areas of the music information memory 13 (n41), the tone color data of each track is read from the header of the song information memory 13, and the tone color register TC is set. (L) (L = 0 to 15) is set (n42). After this, wait state flag WAIT
0 is set (reset) to cancel the wait state (n4
3) The duration time counter TM (L) of all tracks (L = 0 to 15) is set to 0 and cleared (n44). Further, the key press waiting key code table is cleared (n45) and the process returns.

FIG. 9 is a flow chart showing the timer interrupt operation. This interrupt processing is executed at every 96th note timing. For example, if the song has a tempo of quarter note = 120, it is executed once every 1/48 seconds. First, RUN
= 1 and WAIT = 0 (n45,
n46). When RUN = 0, the process is returned as it is because the automatic performance is not being performed. If WAIT = 1, the process is in a waiting state, and the process returns without performing the progress of the gate time or the duration time by the interrupt process.

When RUN = 1 and WAIT = 0,
The reproduction process (FIGS. 10 and 11) and the comparison process (FIG. 12) are executed at n47 and n48. After that, the countdown operation of the gate time is executed, and the sounding data for which the counting of the gate time is finished is muted. That is, the tone generation channel pointer CH is set to 0 at n49. Gate time counter GT of the sounding channel
It is determined whether (CH) is 0 or less (n5
0). If GT (CH) is 0 or less, it is judged whether or not the sounding channel is generating an automatic performance sound (n52). If it is sounding, the sounding channel CH is muted to mute the musical sound. A key-off signal is sent to (n53). On the other hand, when GT (CH) is greater than 0 at n50, the sound generation of this sound generation channel is still ongoing, and since the elapsed time is counted, GT (CH) is counted.
1 is subtracted from (n51). The above operation is CH = 16
Is repeatedly executed until 1 is reached (n54,
n55). Then return.

FIG. 10 is a flow chart showing the reproduction processing operation. First, 0 is set to the track pointer TR (n60), and the following operations are repeatedly executed until TR = 0 to 15 (n69, n70). First, it is determined whether or not the duration counter TM (TR) has become 0 or less (n61). When TM (TR) becomes 0 or less, it is the read timing of the next data, so the data pointed by the read pointer of the track TR is read (n6).
3). If the read data is end data, the data of this track is the end, so no processing is performed and the process proceeds to n69. If the data is other than the end data, the pointer is set to the next data (n65). Next, when the read data is duration data, the duration time of this data is set to TM (TR) (n66 → n68). If the read data is event data, the data processing operation (n
11) is executed (n66 → n67). On the other hand, if it is determined at n61 that TM (TR) is greater than 0, then T
After subtracting 1 from M (TR) (n62), the process proceeds to n69.

FIG. 11 is a flow chart showing the data processing operation. First, it is determined whether the data read from the music information memory 13 is key-on event data (n75). If it is key-on event data, data such as the key code and velocity contained in the key-on event data is set in a predetermined register (KC, etc.) (n76), and then it is determined whether or not the process is a guide part process in the guide mode. Judge (n77). In n77, the guide part is the right hand PRT = 0 or both hands PRT, provided that the guide mode is currently set (GD = 1).
= 2, the key-on event data of the track RTN (0) currently specified in the right-hand part is read,
Or, the guide part is left hand PRT = 1 or both hands PR
When T = 2, and the key-on event data of the track RTN (1) currently designated as the left-hand part is read, a positive determination is made.

When a positive determination is made at n77, the guide part corresponding operation (n81 to n85) is executed, and when this condition is not satisfied, a normal automatic performance sound producing operation (n78 to n80). To execute.

In the normal automatic performance sound generation operation, first, a sound generation channel is allocated for sounding the musical sound of the key-on event data, the channel number is stored in CH (n78), and the key-on signal, key code KC and velocity are stored. , Tone color TC (TR) and channel number CH are output to the sound source 20 (n79). As a result, the sound source 20 starts to generate a predetermined tone signal. After this,
The gate time is stored in GT (CH) (n80).

In the operation corresponding to the guide part, first, the match progress mode flag CPR is judged (n81), and the CPR
When = 1, the key code KC of this key-on event data is added to the key press waiting key code list (n8).
2). After this, 1 is input to WAIT to set the waiting state (n83). When the key pressing instruction display mode is set (IND = 1) (n84), the LED corresponding to the key of the key code KC is turned on (n85),
To return.

FIG. 12 is a flow chart showing the comparison processing operation. This comparison processing compares the contents of the key depression key code list and the key depression waiting key code list in the guide mode, and when there is a matching key code, it is determined that the key corresponding to that key code is correctly depressed. This is an operation for executing a process. First, it is determined whether the guide mode is valid (n90). That is, RUN = 1 and GD =
Judge whether it is 1. If GD = 0, the mode is not the guide mode. If RUN = 0, no automatic performance is performed and even if GD = 1, the guide mode operation is not executed, and therefore the process returns as it is. If the guide mode is valid, the contents of the key depression key code list and the key depression waiting key code list are compared (n91). If there is a match, it is first determined whether or not the key pressing instruction display mode (IND = 1) (n93), and if it is the key pressing instruction display mode, the corresponding LED is turned off (n94). After this, this key code is deleted from both lists (n95).

It is determined whether all the key codes in the key press waiting key code list are deleted by this deletion (n9
6), when the key press waiting key code list is empty and the comparison progress mode (CPR = 1) (n97), W
Set 0 to AIT to cancel the wait state (n98),
Allows automatic performance to proceed and returns.

In this embodiment, the user is prevented from designating the guide part again for the music information in which the guide part is designated in advance, but the guide part can be designated also in such music information. You may Further, the user may be allowed to set the guide part for the music data created on the RAM.
