An OP switch is provided. When the REC switch is operated, the performance information recording standby state is formed. When the PLAY switch is operated or the key is pressed in the state where the performance information recording standby state is formed, the performance information recording state is formed. . In this performance information recording state, performance information such as note-on and note-off generated by the operation on the keyboard is sequentially recorded, and the performance information recording is ended when the STOP switch is operated. Also,
When the PLAY switch is operated after the recording of the performance information is finished, the reproduction is started to perform the automatic performance based on the recorded performance information. If the STOP switch is operated during the reproduction, the automatic performance is stopped.

[0003]

As described above, in the conventional performance apparatus, (1) the REC switch is operated before the performance information is recorded and reproduced. (2) Operate the PLAY switch or keyboard. (3) Play. (4) Operate the STOP switch. (5) Operate the PLAY switch.

A multi-step operation consisting of must be performed. For this reason, it is difficult for infants, young beginners, or elderly beginners to perform these multi-step operations in the proper order, and to effectively use this function despite the recording and playback functions. I can't. Also,
When recording, it is necessary to operate the REC switch prior to the start of this recording to put it in a performance information recording standby state in advance. Therefore, even if you want to hear the phrase you just played and hear it again,
If the C switch is not operated, this phrase will not be recorded and reproduction will be impossible.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a performance apparatus capable of recording and reproducing performance information by a simple operation. .

[0006]

In order to solve the above-mentioned problems, the present invention forms a performance information recording state in response to a predetermined event such as key depression in the performance information recording standby state, and performs a performance operation. In a performance device capable of recording the performance information generated by, and forming a reproduction state in which the recorded performance information is reproduced, timing means for measuring the stop time of the performance operation, and operation means operable from the outside, A first control means for stopping the recording of the performance information and forming the performance information recording standby state when the stop time counted by the timing means exceeds the predetermined time in the performance information recording state; Second control means for stopping the recording of the performance information and forming the reproduction state when the operating means is operated in the performance information recording state,

Third control means for stopping the reproduction of the performance information and forming the performance information recording standby state is provided.

[0007]

In the performance information recording state in which the performance information generated by the performance operation is recorded, when the stop time of the performance operation exceeds a predetermined time, the recording of the performance information is stopped and the performance recording standby state is formed. In the performance information recording state, when the operating means is operated, the recording of the performance information is stopped and the reproduction state is immediately formed. Therefore, when the recording of the desired performance information is completed, only the operation of the operating means is performed, so that the reproduction is started at the same time when the recording of the performance information is stopped. When the operating means is operated in the reproduction state, the reproduction of the performance information is stopped and the performance information recording standby state is formed. Therefore, when a predetermined event such as a key depression is generated next, the performance information recording state is formed, and the performance information generated by the subsequent performance operation is sequentially recorded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the present invention is applied to an electronic musical instrument, which is provided with a keyboard device 1, a control switch group 2 and a display device 3 as shown in FIG. A plurality of keys are arranged in the keyboard device 1, and key depression and key release information of each of these keys is generated and output by the keyboard information generation device 4. The control switch group 2 is provided with various function switches such as a stop / play switch (Stop / Play SW) and a tone color setting switch used in the flow described later.

The on / off information of each switch and the keyboard information generated by the keyboard information generating device 4 are MAI.
Input to the N CPU 5. The MAIN CPU 5 operates in accordance with these input information and the program stored in the ROM 6 to control the display state of the display device 3, and in the performance information recording state, the performance information generated by the keyboard information generation device 4 in the RAM 7. It is stored in a predetermined area. In addition, the MAINCPU 5 is
The tone generator 8 is controlled based on the performance information read from a predetermined area of the AM 7 or the performance information generated by the keyboard information generator 4 in the performance information recording state or the like. The musical tone generator 8 generates musical tone waveform data in accordance with an instruction from the MAINCPU 5, and the D / A converter 9 converts the musical tone waveform data into analog musical tone waveforms. This analog tone waveform is amplified by the amplifier 10 and given to the speaker 11, and is emitted from the speaker 11.

Next, the operation of this embodiment having the above configuration will be described with reference to the flow chart. That is, when the power is turned on, the MAIN CPU 5 operates according to the main routine shown in FIG. 2 to initialize the system (SA1). Next, a predetermined maximum value is set in the non-performance time measuring time counter for measuring the non-performance operation time (the time during which the keyboard device 1 is not operated) (SA).
2). By this processing of SA2, more than a predetermined time,
When there is no performance operation, the performance information recording / playback standby state (REC / PLAY WAIT) is entered (SA3), and thereafter the process is started in accordance with the main loop of SA4 to SA6.

Further, the MAIN CPU 5 executes the processing according to the timer interrupt shown in FIG. 3 at a constant time interval, and determines whether or not the non-performance time measuring time counter becomes equal to or more than the predetermined maximum value. (SB1). Then, only when the time counter is less than the predetermined maximum value, the time counter is incremented (SB2). That is, when the keyboard device 1 is not operated, the non-playing time measuring time counter counts up to the maximum value and stops at the maximum value, and when the keyboard device 1 is operated, a later-described diagram will be given. It is cleared by SC7 of 4.

On the other hand, in the main loop, the event JOB of SA4 is executed according to the flow of FIG. 4, and it is determined whether or not the value of the non-performance time measuring time counter becomes equal to or more than a predetermined value (SC1). Here, the predetermined value is a predetermined time value smaller than the maximum value (SA2).
Then, when the value of the time counter is less than the predetermined value, the process proceeds to SC5 without executing SC2 to SC4.

However, when time counter ≧ predetermined value and the keyboard device 1 is not operated for a predetermined time or more, it is determined whether or not the performance information recording state (during REC). (SC2). If it is in the performance information recording state (during REC), REC end processing is performed (SC3) to forcibly end the performance information recording state, and then the performance information recording / playback standby state (REC / PL
AY WAIT) (SC4).

After the processing of SC4, when the time counter is less than the predetermined value (SC1 is NO), and when the performance information recording state (REC is not in progress) (SC2 is NO), Depending on the presence or absence of operation information from the keyboard information generation device 4 and the control switch group 2,
Determine whether any event has occurred (SC
5). If there is no event, the process returns to the main routine, and if there is any event, it is determined whether or not this event is due to a performance operation (SC6). As a result of this determination, if it is not the performance operation event but the event unrelated to sounding and mute, the event process (SC10) is immediately performed and the process corresponding to this event is executed. But,
This event is a performance operation event, and the keyboard device 1
If it is generated by the operation of, the non-performance time measuring time counter is cleared in response to the occurrence of the performance operation event (SC7).

Next, it is judged whether or not it is in the performance information recording state (during REC) (SC8), and the performance information recording state (R
If it is during EC, after the performance event is recorded (SC9), event processing (SC10) is performed, and sounding processing or mute processing corresponding to the event is performed. Therefore, when in the performance information recording state, the keyboard device 1
The performance operation event generated by the above performance operation is S
By the processing of C9, the music is sequentially recorded in a predetermined area of the RAM 7, and the speaker 11 sequentially generates musical tones having pitches and pitches corresponding to the performance event.

If the result of determination in SC8 is that the performance information recording state (REC is not in progress), it is determined whether or not reproduction is in progress (SC11). If it is being reproduced, event processing is executed according to the event information indicated by the performance information read from the predetermined area of the RAM 7 (SC10). As a result, the musical tone is sequentially generated from the speaker 11 in accordance with the event information read from the predetermined area of the RAM 7, and the previously recorded performance is reproduced.

However, as a result of the determination of SC8 and SC11, if neither the performance information recording state nor the reproduction state is present, the performance information recording / reproduction standby state is set. Then, in such a case, the process proceeds from SC11 to SC12, and it is determined whether or not the event is a REC start event. Here, the REC start event is a trigger event for making a transition from the performance information recording / playback standby state to the performance information recording state, and after any key of the keyboard device 1 is in the recording / playback standby state. This is a performance operation event generated by the first operation. Then, when such a REC start event occurs, the performance information recording state is entered, the process proceeds from SC12 to SC9, the event is stored in a predetermined area of the RAM 7, and then the event process (SC10) is executed. Return to SC1. Therefore, when the operation of the keyboard device 1 is started in the recording / playback standby state to start playing an arbitrary phrase, the performance information from the start of the performance is recorded without any additional switch operation.

On the other hand, the Switch JOB (SA5) in the main routine shown in FIG. 2 is performed according to the flow shown in FIG. 5, and the control switch group 2 is scanned to detect whether any switch has been operated. Yes (SD1). Then, if there is a switch operation in the control switch group 2, it is determined whether or not it is a stop / play switch (Stop / Play SW) (SD2). When various function switches such as tone color setting switches other than the stop / play switch are operated, other SW JOB (SD4) such as changing the tone color according to the operated tone color setting switch
To execute. When the stop / play switch is operated, the Stop / Play SW JOB (S
Execute D3).

This Stop / Play SW JOB
(SD3) is performed according to the flow shown in FIG. 6, and it is determined whether or not the present moment when the stop / play switch is operated is the performance information recording state (during REC) (SE).
1). If the performance information is recorded, REC
After the end processing is performed (SE2) to end the performance information recording, the reproduction (PLAY) is immediately started. Therefore, if an arbitrary phrase is played and recorded in the performance information recording state, and then the stop / play switch is operated by one touch, the reproduction of the phrase played so far is immediately started.

When the stop / play switch is operated and the performance information recording state (REC is not in progress), the recording / playback standby state (REC / PLAY WA) is set.
It is checked whether it is IT) (SE4). Then, in the recording / reproduction standby state, if there is valid data to be reproduced in a predetermined area of the RAM 7, SE4 → SE5 → SE3
Then, the reproduction is started, and if there is no valid data, the flow is exited without starting the reproduction.

Further, if both SE1 and SE4 are NO, it means that neither the performance information recording state nor the recording / reproduction standby state, but the reproduction state. When the stop / play switch is operated in this playback state, playback stop processing is performed to stop the playback (SE6), and then the recording / playback standby state is entered (S6).
E7). Therefore, if the performance is started directly on the keyboard device 1 without performing any switch operation, the first key depression on the keyboard device 1 becomes the above-mentioned trigger event. Therefore, in the flow of FIG. 4, SC8 → SC11
The sequence proceeds to → SC12 → SC9 to transition to the performance information recording state, and recording from the event is started in a predetermined area of the RAM 7. As a result, as described above, the performance information from the time when the performance is started is recorded only by starting the performance on the keyboard device 1 without a separate switch operation.

[0022]

As described above, according to the present invention, when the performance stop time exceeds the predetermined time, the recording of the performance information is stopped to form the performance information recording standby state, and the operation means is operated in the performance information recording state. When it is operated, the recording of the performance information is stopped to form a reproduction state, and when the operating means is operated in the reproduction state, the reproduction of the performance information is stopped to form the performance information recording standby state.
Therefore, the performance information can be recorded and reproduced by an extremely simple operation, and even a young child, a young beginner, or an elderly beginner can effectively use the performance information recording and reproduction function. In addition, since the phrase played without any trouble can be surely recorded and reproduced by one-touch operation and confirmed, it can be effectively used in composing. Further, it is possible to reduce the number of switches as the operating means, and it is possible to reduce the cost of the device.
