A pickable data storage device that can be stored.

[0002]

2. Description of the Related Art
For example, a guitar synthesizer or the like that detects a player's playing input to a string attached to a stringed instrument body by a playing input means and controls sound generation of a sound source and pitch control of musical tones generated by the sound source based on the detected output. Electronic stringed instruments are known. These conventionally known electronic stringed musical instruments are roughly classified into a pitch extraction type and a trigger type based on a difference in a method of detecting a playing input by a player. In the pitch extraction type, a pickup sensor (typically, a magnet-type acoustic sensor) that independently detects the vibration of each string is used. The output of each pickup sensor is a signal in which various harmonic components other than the fundamental frequency component are mixed. Therefore, the fundamental frequency included in the signal is extracted by the pitch extracting means. In addition, the start and end timings of the string vibration are detected by analyzing the output level of the pickup sensor. When the fundamental frequency information is extracted and the condition indicating the start of the string vibration is satisfied, the processing device (CPU of the microprocessor) in the electronic stringed instrument gives a pitch corresponding to the extracted fundamental frequency information to an internal or external sound source. Send data and instruct pronunciation.

Further, when new fundamental frequency information is extracted, the processing device instructs the sound source to change the pitch of the generated musical tone. Further, in response to the establishment of the condition indicating the end of the string vibration, the processing device instructs the sound source that is emitting the string to mute the sound. On the other hand, in a trigger-type guitar synthesizer, a string trigger switch or a string trigger pickup for sensing the start of string vibration is generally provided for each string, and a fret operation position for each of the strings is sensed on a fingerboard. (For example, a number of on / off type fret switches arranged in a matrix on a finger board, or a coordinate detection type or a resistance value detection type for each string by a tablet, or a finger board) A fret switch of a type in which a conductive string is stretched over the string, a minute current flows through the strings, and a fret contact is provided at each string depressed position is provided. In operation, when the start of vibration of the string is detected through the string trigger pickup, the processing device reads the fret operation position information of the string (information obtained through the fret switch) and starts the fret position information and vibration. The pitch data is created from the string information and the sound generation is instructed to an internal or external sound source. As a result, a tone having the designated pitch is generated from the sound source. The trigger type includes a so-called switching type and a pickup type using a string trigger pickup because a string trigger switch and a fret switch are used.

However, in such a conventional electronic stringed musical instrument, in either of the pitch extraction type and the trigger type, a player usually uses a finger to determine the pitch of a musical tone to be produced with the left finger. Pitch designation operation on the board (fret operation to press the fret)
On the other hand, a picking operation or a picking stroke operation (hereinafter, referred to as "picking operation") on the string is performed with the right finger to instruct the musical sound generating means to start generating a musical sound at the designated pitch. Therefore, the player must perform the performance by combining the operations with both fingers in a complicated manner, and cannot perform only the picking operation with the right finger, but requires a high performance technique. In addition, in the case of playing a stringed instrument, as described above, in addition to the pitch designation operation by the left hand, the string must be picked accurately and quickly by the right hand at the same time or at a different timing from the pitch designation operation. There are many types of picking, and these many types of picking operations must be appropriately selected according to the progress of the music.Therefore, not only learning of the pitch designation operation but also picking operation by the right hand are performed. You also have to learn.

[0005] However, conventionally, an electronic musical instrument whose main purpose is to learn the picking operation has not yet been developed. For stringed players (especially beginners),
While actually listening to various picking sounds or picking stroke sounds (hereinafter referred to as “picking sounds”),
The type of picking, the timing of the picking operation, and the accent during the picking operation (the strength of the picking sound) can be determined without the guidance of a teacher or expert.
There is a demand for an electronic musical instrument that can be quickly and easily learned anytime, anywhere. The types of picking include (1) down picking, (2) up picking, (3) alternate picking, (4) carter family picking, (5) arpeggio picking, and (6) chopper picking. There is base picking. In addition, picking data used for playing a stringed instrument (for example , the timing of
It is desired that a player can freely program data according to the tune and tune, and automatically reproduce the result, thereby making it possible to immediately judge the quality of the picking operation of the user. . In addition, for beginners, in order to hear the model picking sound by the model player, picking data according to the picking operation by the model player is faithfully recorded in advance, and the automatic model picking sound according to this data can be reproduced The emergence of new electronic musical instruments is desired.

However, conventionally, an electronic musical instrument that allows a player to program picking data arbitrarily and an electronic musical instrument that can record and reproduce picking data according to a picking operation state performed in real time have been developed. I didn't. Furthermore, it is difficult for a stringed instrument player (especially a beginner) to perform the picking operation in real time as described above, and it is possible to input (store) the sounding timing of the picking sound to be sounded in a stepwise manner. It is desirable to do. However, conventionally, an electronic musical instrument capable of inputting the sounding timing of a picking sound to be sounded stepwise has not yet been developed.

[0007]

The CPU 37 temporarily stores the tempo information corresponding to the setting of the tempo volume 15 in the latch 5.
After setting to 2, the signal is given to the frequency dividing circuit 53. Therefore, the frequency dividing circuit 53 determines the frequency division of the master clock signal from the CPU 37. The frequency-divided clock signal is output as a shift clock signal for the D-type flip-flops F8 to F19. For this reason, the picking data is read out at a tempo corresponding to the transmission timing of the shift clock signal, and each trigger LED 1 is read.

I do. As a result of the determination, there is no change in their contents, and therefore, while they match each other, the matching circuit 54...
Outputs a coincidence signal (high-level signal) to the inverters 17 to
The output is inverted by 112. On the other hand, when the content of the current picking operation differs from the content of the previous picking data, for example, when a new string 4 is picked, each matching circuit 54... Outputs a mismatch signal (low level signal) to the inverters 17 to 112. And output the result. as a result,
The inverted output signal is supplied to the latches 55... As a latch signal, and is also supplied to the read / write control circuit 56 as a capture signal. By the capture signal, the trigger signal Ts indicating the content of the current picking data is captured by the read / write control circuit 56. The time interval (t) between the time when the content of the previous picking data changes and the time when the content of the current picking data changes is counted by the clock circuit 57. The counted value is taken into the read / write control circuit 56 as data indicating the interval of the tone generation timing, that is, the picking time. Therefore,
Rest length data as well as note length are taken in. The above picking data is applied to the write information generation circuit 58. The picking data given to the write information generating circuit 58 is stored in the ROM / RAM card unit 33 in the R.
The data is written to the OM / RAM card 17 in a predetermined order. The picking data is used for automatically generating a picking sound when the second or third automatic picking performance mode OP ₂ or OP _{3 is} set. Each of these picking data is sent to the ROM / RAM card unit 33, and is written to the ROM / RAM card 17 in a predetermined order. In this case, the read / write control circuit 56
The address control unit 46 of the M / RAM card unit 33 is configured to receive write address data.

Normal Mode Performance Processing Operation As described above, when the mode switch 13 is set to the normal mode N, a normal performance is performed, and the performance of the player with respect to the pitch specifying switch PSW which is the pitch specifying means. A predetermined pitch is specified by a pitch specifying operation, and the start of generation of a musical tone at the specified pitch is determined by a trigger signal picked up by a trigger pick-up TPU in accordance with the player picking the string 4 and a tone generator circuit block. 38. Therefore, a tone having a predetermined pitch is emitted from the tone generator circuit block 38. B. When the write operation mode switch 13 is set to the recording mode R, the desired picking data is written to the RAM card of the ROM / RAM card 17.
The writing process includes a real-time input for recording picking data (sound generation timing and picking power) in real time based on an actual performance (picking) and a step input for recording picking data step by step for each note. There are two types of processing.

Repeats step S-2 until it is checked that picking is present. If YES, the picked string number (first
The string number of any of the strings from the sixth string to the sixth string) and its picking force (the picking strength) are detected (step S-3).
Further, in order to obtain the data of the picking timing (time), the time of the timer at that time is latched (step S-4), and the address of the ROM / RAM card 17 is incremented by +1 to obtain the string number. The data of the picking force and the timing of the picking are stored in the RAM card (step S-5). Subsequently, it is checked whether an end switch (not shown) for terminating the writing has been turned on (step S-6), and if NO, the process returns to the start of the writing and the processing after step S-1 is repeated.
In the case of S, the end flag is set to 1 to indicate that the write operation has been completed (step S-7), and then this flow is terminated. As described above, this flow is based on the real-time ROM / R processing of picking data obtained when the player performs a picking operation at an arbitrary timing.
The processing of storing the data in the RAM card of the AM card 17 is performed, and the performance of down picking as shown in the 4/4 time TAB musical score shown in FIG. 6B is performed at the timing (time) ( t ₁ ~t ₆₎ and picking force (strongest to weakly), if made sequentially each string 4 (first string to the sixth string), picking data contents as shown in FIG. 6E ROM / RAM card It is stored in each of the memory addresses (1 to 6) in the 17 RAM cards. That is, the first picking of the first measure of FIG. 6B, at respective picking time t ₁ ~t _6,
Each picking power (strongest, medium, medium, medium, medium, weak)
When the first string is down-picked in order from the sixth string with the strength of, the picking data obtained by the down-picking operation is stored in the memory addresses 1 to 6 of the RAM card, respectively. This means that the picking data stored in the addresses 1 to 6 is stored as one set of the down-picking data of the first beat. In the next second beat in FIG. 6B,
Picking is attached accent> to, in response to the picking time t ₇ ~t ₁₂ as shown in FIG. 6D, the down picking playing strongest picking force to the first string is made in order from the sixth string, Similarly, picking data having the contents shown in FIG. 6C is written to the corresponding memory addresses 7 to 12 of the RAM card. In this writing process, the string number (the first to sixth strings)
Is stored as 3-bit / 8-step chord code data as shown in FIG. 6E, and the picking force is also stored as 3-bit 3-step data as shown in FIG. 6E.
The number of bits of these data can be set arbitrarily according to the memory capacity of the RAM card.

B. Step Input Process Operation Next, another write process, ie, a write process operation based on a step input, will be described by taking as an example a case where picking data as shown in FIG. 6B is stored stepwise. For this step input,
Unlike the case of real-time input, different writing processing is performed according to the type (aspect) of picking. The picking type determination processing of the CPU 37 at that time will be described with reference to the flowchart shown in FIG. This flow is started by interrupting a timer with respect to a main routine (not shown) or repeatedly operating at a predetermined timing. First, the type of picking data to be recorded is checked (step P-1). If down-picking, down-picking data writing processing is performed (step P-1).
-2) In the case of up picking, write processing of up picking data is performed (step P-3). In the case of arpeggio picking, write processing of arpeggio picking data is performed (step P-4). This flow ends. FIG. 8A shows FIG.
FIG. 4B is a flowchart showing the processing operation of the CPU 37 when performing step-writing processing of down-picking data as shown in FIG. B. This flow also includes a timer interrupt to a main routine (not shown) or a predetermined timing. And starts repeatedly. In the figure, when writing is started,
First, "1" representing the first fret is substituted into the corresponding fret number register FN-RE (step T-1). Then, it is checked whether or not the pitch designation switch PSW of the first fret, which is the corresponding fret, has been turned on to input data indicating the sounding timing position in the step input (step T-2). The fret number flag is set to 1 (step T-3), and if NO, the corresponding fret number flag is set to 0 (step T-3).
-4) indicates that the first fret is currently turned on or not turned on, respectively.
Here, as shown in FIG.
Of the fret, the first to sixteenth fret positions correspond to steps obtained by dividing one bar in the score shown in FIG. 6B into 16 equal parts, and in the case of 4/4 time signature, a sixteenth note as a minimum unit Will be supported. Therefore, when the first fret is pressed, a timing (that is, a tone generation timing) to be input as the first picking data is designated at the position of the first beat in the first bar in FIG. 6B.

Subsequent to step T-3, it is checked whether any of the first to sixth strings has been picked (step T-0). If NO, this string is checked until picking is performed. Step T-4 is repeated. YE
In the case of S, the picking force (the picking strength) is detected (step T-5). In this embodiment,
This detection data is represented as the picking force of all of the sixth to first strings. Even if one specific string is not picked, only the pitch specifying switch PSW is turned on. You may make it possible to input the sounding timing data corresponding to the switch PSW position. Next, R corresponding to sounding timing 1 shown in FIG.
In order to store down picking data in the memory area of the memory address of the AM card, predetermined sounding timing (time) data (at the position of the first beat, the sixth string) in order from the sixth string to the first string. From the first string to the first string, data indicating the sounding timing of each string to be sounded at a predetermined time interval or data indicating the time interval of the sounding timing of each string) is stored (step T-6). . The sixth
The sounding timing data between the strings to be sequentially sounded from the strings to the first string is automatically stored in the storage area based on an instruction from the CPU 37. The sounding timing data for each string is The player may be able to set the program by manual operation or the like. Thus, the beginning of the first bar of the score shown in FIG. 6B (the first beat)
9A, the picking force 10 of the medium strength at the position of the sound generation timing 1 in FIG. 9A.
When the value is 0, the same picking data as when the picking operation is performed on all of the sixth to first strings is input. Subsequently, the corresponding fret number register FN
The data of -RE is incremented by 1 (step T-8), and in this case, 1 is added to data 1 which is the first fret.
To change the data to data 2 indicating the second fret. Then, the corresponding fret number register FN-
It is checked whether or not the RE data is equal to or more than 17 (step T-8). Here, it is still 2 and 2 <1.
7, so the determination is NO, and the process returns to step T-2. If YES, it means that the step input of the picking data corresponding to all the fret up to the 16th fret has been completed (that is, the step input for one bar), so this flow is ended. That is, this flow shows the processing operation when step picking of picking data for one bar is performed based on the pressing operation of the first to 16th frets.

After returning to step T-2, the same processing as in the case of the first fret position is performed in order to input picking data to the step corresponding to the second fret position shown in FIG. However, the picking content to be recorded is, as shown in the score of FIG. 6B, at the timings corresponding to the second to fourth fret positions, that is, at the timings 2 to 4 shown in FIG. Since there is not, the content of the corresponding fret number register is incremented to 5 in step T-7. In order to input picking data relating to the picking of the second beat of the first bar in the score of FIG. 6B, while turning on the fifth fret, one of the strings 4 is set to the strongest position for accenting. Picking with picking power. Then, at the position of the sounding timing 5 corresponding to the fifth fret position in FIG. 9, the predetermined sounding timing data and all the predetermined strings are sequentially arranged from the sixth string to the first string in the same manner as in the case of the position at the previous timing 1. And the data 11 of the strongest picking force for the first string are input in steps. Next, in order to input the picking data of the third beat of the first bar in FIG. 6B, this time, one of the strings 4 should be picked while turning on the ninth fret position, and the sound should be generated sequentially. By turning on the fret position corresponding to the timing and picking any one of the strings, recording by the necessary step input is continued in sequence. In the case of this embodiment, a mark MRK indicating the existence position of the first to 16th fret positions is displayed on the side surface of the neck portion of the electronic stringed instrument, and this mark MRK is used when recording by the above-described steps and the like. The function of assisting the step input operation as a guide for the fret operation of turning on each fret switch FSW. Although the above-described example is for inputting picking data relating to down-picking, the case of inputting data relating to up-picking or arpeggio picking can be similarly performed according to the above-described example.

C. When the first automatic picking performance processing operation mode switch 13 is selected and set to the first auto picking playing mode OP ₁ is, ROM / picking data previously stored in the RAM card 17 (predetermined picking timing, predetermined picking In this embodiment, unless the fret is operated at a predetermined fret position, a musical tone having the same open string pitch as that when the picking operation is performed in the open string operation state is performed in this embodiment. The sound is automatically emitted from the tone generator circuit block 38 at the sounding timing according to the picking data, and at the lighting timing according to the picking data, the predetermined portion of each string 4.
Light emission is automatically displayed in the order of the strings. And
The player listens to the automatic picking sound generated at the timing of the automatic picking performance, and quickly and easily recognizes the type of picking and picking by visually observing the light emission display mode of the string 4 as described later. , Etc. can be learned. Hereinafter, the operation of the first auto-picking performance mode OP _1, further be described separately the type of picking.

A. Alternate picking Now, switch the mode switch 13 from the normal mode N to the first.
To auto-picking performance mode OP _1. Then, the read address of the address control unit 46 is reset to “0” by the CPU 37. Then, when the auto picking start switch OSW is turned on, the ROM / R
The picking data at the head address of the AM card 17 is set in the latch 52 of the trigger-side LED unit 35. In this case, assuming that the picking data at the start address of the ROM / RAM card 17 is alternate picking, the AND gates A12 to A25 in FIG. 5A are opened. As a result, a closed lube is formed between the flip-flops F8 to F19, and a circulating counter of 12 bullets is formed. Therefore, the "1" signal is shifted between the flip-flops F8 to F19 at the cycle of the frequency-divided clock signal corresponding to the set tempo data sent from the frequency-dividing circuit 53. This "1" signal is output from the flip-flop F8 to the flip-flop F13.
During the shift to the gates A12 to A12
Since the OR gates O2 to O7 are sequentially input through A17, a "1" signal is sequentially output from these OR gates O2 to O7. Therefore, as shown in FIGS. 4 and 5A, each flip-flop F
Output lines ₁ to F6 and each trigger LED 12 _{1 to} 12
₆ are sequentially supplied with a "1" signal. Therefore, the "1" signal given to the output lines of the flip-flops F6 to F1 is sent to the tone generator 41 through the key code generation circuit 36 as a tone trigger signal, and responds to the tone trigger signals Ts. Accordingly, the corresponding musical tones are generated sequentially from the sixth string to the first string. These musical tones will be pronounced. These tones produce picking sounds in the down direction. At the same time, since the "1" signal is applied to each trigger LED 10 ₆ to 10 _1, each trigger LED 10 ₆ ~
10 ₁ becomes to be sequentially turned towards the first string from the sixth string. By this lighting display, picking in the down direction is visually displayed. Conversely, while this "1" signal is shifted from the flip-flop F14 to the flip-flop F19, it is sequentially input to each of the OR gates O7 to O2 via the AND gate A25A20. , The "1" signal is sequentially transmitted from the flip-flops F1 to F6 and the trigger L
ED12 sequentially "1" to _{1-12 6} signal is given. Therefore, contrary to the picking sound in the down direction, the picking sound in the up direction, which is generated sequentially from the first string to the sixth string, is produced. At the same time,
Since "1" signal is applied to each trigger LED 10 ₁ to 10 _6, the trigger LED 10 ₁ to 10 ₆ is a be sequentially turned towards the first string to the sixth string. With this lighting display, picking in the up direction is visually displayed. As a result, each of the flip-flops F8 to F1
9, the sounding state and display state of the picking sound of the alternate picking can be realized.

[0034] b. If the down-picking data is down-picking data, the down-picking data is read from the ROM / RAM card 17 and set in the latch 52. Then, the AND gates A10-A17 are opened. become. Thereby, the flip-flops F8 to F13
An open loop is formed between them to form a six-stage circulating counter. Therefore, the "1" signal is sequentially shifted between the flip-flops F8 to F18 at a speed corresponding to the set tempo. As a result, as described above, each of the flip-flops F6 to F1
Are sequentially given to the output lines of the first and second strings, that is, in order from the sixth string to the first string,
A picking sound will be emitted. Therefore, a picking sound only in the down direction is produced by this sounding state. At the same time, the trigger LED10 ₆ ~
Since 10 ₁ are sequentially turned towards the first string from the sixth string, by the lighting display state, so that the picking down direction only is visual indicia. In this way, in fact, without the need to pick the string 4, automatically, it is possible to sound the picking sound according to the desired picking data, the trigger LED 10 ₁ to 10 ₆ corresponding to the sound Each trigger LE is displayed while being lit sequentially while confirming the picking sound by ear.
By observing the lighting direction and order of D10..., Various picking operations can be smoothly and reliably learned. In the case of the up picking, the same processing operation as in the picking in the up direction in the alternate picking described above is performed, and the description is omitted. By adjusting the tempo volume 15 in FIG. 1A, the reading tempo of the picking data, that is, the reproduction / performance tempo can be arbitrarily variably set.

D. The second auto-picking performance processing operation mode switch 13 is if selected set to the second automatic picking performance mode OP _2, is a mode for reproducing, performance picking data written by real-time input processing operation. FIG. 6F shows a processing operation when the picking data written and processed by real-time input according to the picking timing of the musical score shown in FIG. FIG. This flow is started by a timer interrupt or a repeated operation at a predetermined timing with respect to a main routine (not shown) of the CPU 37. After the performance starts, the timer in the CPU 37 is cleared (step S-8), and the address of the memory of the ROM / RAM card 17 storing the picking data is incremented by +1. In this case, the memory address 1 in FIG. The picking data consisting of the stored string number to be picked, the picking timing and the picking force is represented by R
Read sequentially from the OM / RAM card 17 (step S
-9). Checks whether data to be read out have continued has run out (Step S-10), the automatic sound processing picking sound when YES is seen to have ended, and the flow ends. If NO, check the count is picking timing data time of the timer, i.e. picking time to be produce musical sounds, whether the host vehicle has reached the example t ₁ (step S-11), data if NO
Now it is YES this check until it reaches its time _{t 1}
Repeat until. Subsequently, the picking data read out, that is, a tone according to each data of the string number (101) and the picking force (111) corresponding to the memory address 1 as shown in FIG.
_In step S-12, a tone generation start control signal is sent to the tone generator circuit 41 in order to generate a tone in step S1. And
Returning to step S-8, likewise, now performs the processing for sounding the picking sound in the picking timing data time t ₂ reads the next picking data memory in the memory address 2 below, this process Is performed for all addresses, and when there is no more data to be read, this flow ends. In this case, combined with such second auto picking performance mode OP ₂ to the performance of the automatic picking, if the pitch designation or code specified by pressing the fret switch PSW in a predetermined order performer with the left hand, In step S-12
Te, corresponding to the fret switch PSW that the pressing operation
The musical tone or chord having the pitch indicated by the detected pitch code is automatically read at the timing according to the picking data (the timing indicated by the picking timing data).
(At the time of the arrival of the imming) , and it is possible to perform the music with the melody and the chord performance. Therefore, the player can concentrate all his or her nerves on the fret operation with the left hand without paying attention to the picking operation with the right hand, so that the melody performance or the like can be performed accurately. If the tempo of the auto-picking data is variably set by adjusting the tempo volume 15, the picking sound can be reproduced and played at a timing different from the input timing at the time of recording by real-time input.

E. When the third auto picking performance processing operation mode switch 13 is set to the third auto picking playing mode OP ₃ is a mode for reproducing play picking data written by the step input processing operation. FIG. 8B is a flowchart of a processing operation in which the picking data, which has been written by the step input in accordance with the flowchart of FIG. It is. This flow starts with a timer interrupt or a repeated operation at a predetermined timing with respect to a main routine (not shown) in the operation of the CPU 37. After the start of the performance, first, 1 is substituted for the content of the corresponding fret number register FN-RE (step T-9), and first, preparation is made for reading out the picking data corresponding to the first fret position, that is, the picking data at the timing 1 in FIG. 9A. I do. Next, it is checked whether or not 1 is set in the corresponding fret number flowchart FN-FR (step 10). If YES, the corresponding fret number is stored in the corresponding storage area of the memory address in the ROM / RAM card 17 corresponding to the first fret position. Since the picking data to be sounded on the first beat is stored, the picking data (sound generation timing and picking power) stored in the storage area corresponding to the address is read. For example, at a time (first beat) corresponding to timing 1 as shown in FIG. 9, in order from the sixth string to the first string,
Each data indicating the picking timing and the picking force (100) for each string is read, and it is checked whether there is no more data to be read (step T-1).
2) If YES, it is considered that the automatic picking performance has ended, and this flow ends. If NO, a tone generation control signal is sent to the tone generator circuit block 38 in accordance with the read picking data to generate a picking sound at a picking timing corresponding to each string at the read picking timing (first beat). (Step T-13). Subsequently, the content of the fret number register FN-RE is incremented by one, and the next fret number, in this case, data 2 indicating the second fret is set (step T-14). Then, it is checked whether or not the data content of the fret number register FN-RE is equal to or more than 17 (step T-15). At present, 2 ≦ 17, and since it is NO, the process returns to step T-10, and step T-10. By repeating the following processing in the same manner, picking data having contents as shown in FIG. 9 is sequentially read out and automatic sound generation control is executed. If FN-RE ≧ 17 in step T-15, the reading and reproduction of all the recorded data have been completed, and this flow ends. In this case, in accordance with the performance by such third auto picking performance mode OP _3, performs fret manipulation in a predetermined order performer with the left hand, by performing the pitch designation or code specified, corresponding to the fret manipulation A musical tone or chord having a pitch can be generated at a timing according to the performance of automatic picking. Also,
By adjusting the tempo volume 15 of the automatic picking performance, the time interval between the sounding timing of the picking sound for each string or the sounding timing of the picking sound for each beat can be adjusted according to the tempo. It can be adjusted according to the data.
Further, in the above embodiment, the step input in the down picking is automatically performed. However, the automatic performance of the step input in the up picking, the alternate picking and other different types of picking is also possible.

<Effects of Embodiment> As described above, in the above embodiment, the ROM / RAM card 17 storing the picking data is stored in the card setting section 16.
To the first auto-picking performance mode OP ₁
When the automatic picking start / stop switch OSW is turned on, the automatic performance of the open string picking sound without pressing the fret is performed according to the tempo arbitrarily set by the tempo volume 15. Since the sound is performed at a volume corresponding to the picking strength indicated by the picking data, the player simply designates the desired pitch by pressing the fret in accordance with the sounding timing of the picking sound, and the desired sound alone is obtained. A picking sound can be performed with a high or desired chord. Also, the trigger LED 10,
The light guides 10a and the like are used to cause each string 4 to emit light in accordance with the predetermined order in accordance with the picking data, so that the player can navigate to the light emission display of the string 4 and play more easily. It can be performed. Further, according to the above-described embodiment, predetermined picking data is stored in the ROM / RAM card 17 by real-time input based on an actual performance performed by the player or step input for each sound, and the picking data is stored in the second or the second memory, respectively. When the third auto-picking performance mode OP ₂ or OP ₃ is set, it is possible to read out and perform an automatic picking performance at an arbitrary tempo, and in addition to the automatic picking performance, the player specifies a pitch by operating a fret. Alternatively, simply by designating a chord, the performance can be easily performed at the designated pitch or chord in accordance with the automatic picking performance. Also, in this case, if the strings 4 are also displayed by light emission,
Since the timing of picking, such as up / down, is navigated, a large guide for playing can be obtained, especially for beginners. Further, at the time of recording by the step input, the sounding timing of the picking sound to be sounded can be inputted by either the pressing operation of the pitch specifying switch PSW or the picking operation of the switch PSW and the string. Therefore, it is not necessary to separately provide a switch or the like as an input means for inputting the data of the sound generation timing, and an electronic stringed instrument capable of recording picking data by step input with a simple configuration can be obtained.

<Modified Embodiment> In the above embodiment, an LED (light emitting diode) is used as the light source of the light emitting display means.
Other display elements may be used as long as they can be visually displayed, such as lamps. Further, the number of trigger LEDs 10 and the number of light guides 10a provided on one string are not limited to four, and the light emitting display element may be directly connected to the predetermined string without using the light guide 10a. The light emitting display element may be buried in a location, and a predetermined fret position or the like may be displayed by light emission using the light emitting display element. Further, an optical fiber may be used instead of the light guide 10a. In this case, the internal structure of the string 4 is as shown in FIG. 10, and those having the same reference numerals as those in FIG. 2 have the same functions. Things. In FIG. 10, a plurality of optical fibers 1 are provided at predetermined positions in the outer circumferential direction of a string 4 having one end fixed to a string support plate 30 a by a fixture 30.
0a-2 is disposed, and one end of the optical fiber 10a-2 is embedded in a mounting plate 31 on which each trigger LED 10 is mounted.
A structure in which light is emitted from the other end may be employed.
The outer circumferences of the optical fiber 10a-2 and the string 4 are both protected by a translucent protective tube 10d. Further, in the above-described embodiment, the ROM / RAM card 17 is used as the picking data storage means. However, a built-in ROM or RAM, a magnetic tape, a magnetic disk, an optical disk, or the like may be used. The picking data may include various picking data such as arpeggio data and chopper-based picking in addition to the above-described case. Further, the present invention may be applied to other electronic musical instruments such as an electronic keyboard musical instrument in addition to the electronic stringed musical instrument, and the present invention is not limited to the above-described embodiment, and the same applies to other means and names. It is. Further, as the pitch designation means, in addition to the switching pitch designation switch PSW as in this embodiment, a resistance detection type (for example, US Pat. No. 4,235,141),
A method in which a conductive string to which a current is supplied is brought into contact with a conductive fret piece (for example, US Pat. No. 4,658,69).
0), a method in which an ultrasonic signal is propagated to each string, and a fret position is detected based on a time required from transmission of the ultrasonic signal to reception of the reflected wave signal (for example, Japanese Patent Laid-Open No.
-99790). Further, in addition to the trigger pickup TPU as in this embodiment, a system using a hall element and a magnet (the aforementioned U.S. Pat. No. 4,658,690) and a touch switch system (for example, U.S. Pat. 4,336,734,4,33
9,979, 4,248,128, 4,078,46
4), a method of shielding a laser beam may be used. Although the above embodiment is an electronic stringed instrument of a trigger detection type, the present invention determines a corresponding pitch based on a string vibration fundamental period (pitch) generated at the time of a string picking operation, that is, a so-called pitch extraction. It is also applicable to electronic stringed instruments of the type. In this case, if the picking data is configured to store the pitch data or the pitch data corresponding to the pitch data, in addition to the picking timing or the picking force data, the picking data is reproduced. Thus, it is possible to perform an automatic performance using a picking sound in accordance with the picking data at a predetermined pitch without performing not only the picking operation but also the pitch specifying operation.
