DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described with reference to the drawings.

FIG. 1 is a hardware block diagram of the electronic musical instrument of the present invention. A CPU 1 controls the operation of the electronic musical instrument, and is connected to other components via a data and address bus 5. The ROM 4 stores a control program and the like, and the CPU 1 executes a predetermined process according to the control program. The RAM 3 includes a register for temporarily storing data during various processes, and stores automatic performance data and the like. The switch detection circuit 10 is a circuit that detects an operation state of the panel switch 9 and outputs switch operation data to the CPU 1 via the bus 5. The panel switch 9 includes a function switch for executing various functions of the electronic musical instrument, a data input switch for automatic performance data, and the like. The display circuit 8 is for displaying the operation state of the electronic musical instrument and various data, and includes an LCD display and its driving circuit. The tone generator 7 is a circuit for generating an automatic performance sound, and generates a tone signal by a known waveform memory system, an FM system, or the like. The tone signal generated by the tone generator 7 is generated via the sound system 6. The timer 2 outputs an interrupt signal to the CPU every predetermined period described later.
Send to 1.

FIG. 2 shows a display mode when a function is executed. (A) is a display screen of the display circuit 8 when a song edit job (automatic performance data editing function) is executed. In this example, it is the screen when the quantize function is executed,
This function aligns automatic performance data between bar numbers 001 to 064 with the timing of a 32nd note. The edit range (measure number 001 or 064) and the type of note to be quantized (32 notes) can be arbitrarily set by a switch on the panel switch 9.

FIG. 2B shows a state in which the execution switch (not shown) is pressed from the state of FIG. In this state, "Now Ex" indicating that the function is being executed is displayed on the LCD display.
The word "ecuting" is displayed, and a picture of the metronome is displayed. This metronome picture has a predetermined period (150 msec = tempo 400 (4 per minute).
400 msecs) to 1500 msec = tempo 40,
Preferably 333 msec = tempo 180 to 1000
The display position of the pendulum is changed alternately left and right every msec = tempo 60). By changing the display position of the metronome pendulum at such time intervals,
The display matches the operation of the actual metronome and does not give a sense of incongruity.

As described above, while the function is being executed, the picture of the metronome in which the pendulum moves every predetermined time is displayed. When the execution is completed, the screen returns to the original screen.

FIGS. 3 and 4 are flowcharts showing the detailed operation of the present invention. FIG. 3 shows the main routine.
When a power switch (not shown) is turned on, the CPU 1
The processing is started according to the control program stored in M4. First, in step s1, initialization is performed.
Initialize various registers and flags. Next, the process proceeds to step s2, and it is determined whether or not the job execution switch is pressed on the panel switch 9. If the button is pressed, the process proceeds to step s3, and “Now”
A picture of the metronome is displayed together with the characters "Executing" (see FIG. 2B). The display position of the pendulum at this time is on the right side. Next, the process proceeds to step s4, and a metronome flag indicating that a metronome is being displayed is turned on. Subsequently, in step s5, job processing is executed. The job processing includes, for example, the quantization processing in the description of FIG. 2 and the copying, moving, deleting, and modifying of automatic performance data (changing data such as velocity).
One of these functions is set by various function setting switches (not shown) of the panel switch 9, and the set function is executed when the job execution switch is turned on. This process usually takes about several seconds, during which time the pendulum of the metronome display is moved left and right by the interrupt process described later, so that the user can recognize that the electronic musical instrument is functioning reliably.

When the job processing in step s5 is completed,
Proceed to step s6, turn off the metronome flag,
Then, the process proceeds to step s7 to turn off the metronome display. Thereafter, or if there is no job execution instruction in step s2, the process proceeds to step s8, performs other processes, and repeats the process of returning to step s2. Here, other processing includes processing of panel switch 9, RA
The automatic performance data stored in M7 is read out and the tone generator circuit 7 is read out.

FIG. 4 shows the above-mentioned predetermined period (150 msec).
From 1500 msec, preferably from 333 msec to 1000 msec).
When an interrupt signal is generated from the timer 2, the CPU 1 interrupts the processing of the main routine and executes this interrupt processing. First, in step s9, it is determined whether the metronome flag is on. The metronome flag is turned on in step s4 in the main routine and turned off in step s6. If the result of the determination is on, the process proceeds to step s10, where it is determined whether the pendulum position of the metronome display is currently on the right. If it is right, the process proceeds to step s11, where the pendulum position is displayed on the left. Otherwise, the process proceeds to step s12, where the pendulum position is displayed on the right. When these processes are completed, or when it is determined in step s9 that the metronome flag is off, the interrupt process is completed and the process returns to the main routine.

In the above embodiment, the automatic performance (automatic

[0018]

As described above, according to the present invention, the metronome picture is displayed on the display device while the automatic performance data editing process is being executed, and the metronome pendulum is displayed at a predetermined period during the process. Because it keeps moving, it is easy to confirm that the electronic musical instrument is operating simply by looking at the display device, even if the keyboard or panel switch does not work, especially when executing a function that takes time to process. Therefore, there is an effect that the user is not anxious that the user may be out of order. In addition, since the metronome is displayed and the pendulum is kept moving, there is an effect that the user is not bored during the waiting time. Furthermore, since the pendulum of the metronome is moved at a cycle corresponding to the tempo set in the automatic performance, there is an effect that the tempo set in the automatic performance can be easily visually recognized.
