[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device such as an electronic musical instrument, and more particularly to an electronic device in which a user can set a desired function by using a function switch.

[0002]

2. Description of the Related Art There are many types of functions of an electronic device compared to the area of the panel surface of the electronic device, and it may be difficult to provide a number of function switches corresponding to those functions.
In such a case, conventionally, the following two types of function setting units have been used as electronic device function setting units. <First Type> An electronic device that sets functions corresponding to a combination of two types of function switches when the two types of function switches are pressed. <Second type> An electronic device in which different functions are set when a certain function switch is pressed for a short time and when a certain function switch is pressed for a long time.

[0003]

The first type of electronic device described above has a drawback that when the distance between two switches corresponding to a desired function is large, it is difficult to press the switches. there were. In addition, the user must remember the combination of switches, such as which switch to press and which switch to press, in order to operate the desired function, and there is a problem that the burden on the operation of the user is large. . In the above-described second type of electronic device, a function set when the switch is pressed for a short time and a function set when the switch is pressed for a long time in order to prevent a user from erroneous operation. Had to be related. The present invention was made under such a background,
It is an object of the present invention to provide a function setting device of an electronic device which is capable of instructing many functions with one switch, and which is easy to use for a user to learn how to operate the switch and which has excellent operability.

[0004]

A function setting device for an electronic device according to the present invention is provided on a panel of the electronic device and corresponds to a function switch that can be turned on / off by a user's operation, and a function switch corresponding to the function switch. (1) when the function switch is pressed for the first time, performs first processing corresponding to the function switch and sets the lighting means to a first lighting state; When the function switch is pressed again for a predetermined time or more while being set to the first processing state, the lighting unit is set to a second lighting state, and (3) the second lighting state When the function switch is pressed again, a second control different from the first process is performed, and the control unit sets the lighting unit to a third lighting state.

[0005]

In the above configuration, when the function switch is pressed for the first time, the first processing corresponding to the function switch is executed, and the lighting means enters the first lighting state. If the same function switch is pressed for a predetermined time or more while the first processing state is set, the lighting state of the lighting means is changed to the second lighting state. A second process different from the first process is performed. The method of operating the function switches provided on this panel can be determined by the lighting mode of the lighting means, so that the operability of the electronic device as a function setting device is improved.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a sound source module device according to an embodiment of the present invention. FIG. 2 is a front view showing a front panel of the apparatus, and FIG. 3 is a rear view showing a rear panel.

Reference numeral 2 denotes a panel switch group, which includes a GM mode switch K1, a DO mode switch K2, a CM mode switch K3, and the like provided on the front panel as shown in FIG. Each of the mode switches K1 to K3 is a self-returning type push-button type switch. It is provided as a child. A change in the on / off state of each switch is detected as an event by the CPU 1 through the panel switch interface 3. In FIG. 1, reference numeral 4 denotes an LED group, and these LEDs are mounted on the front panel together with the mode switches K1, K2, and K3.

Each storage area of M12 is used as registers and flags for storing various control information. The main registers and flags are listed below. Mode register MODE: Mode switches K1, K
This register is updated when any one of 2 and K3 is turned on, and a value corresponding to the mode switch that has been turned on is written. Timer flag TMF: A flag that is updated when the same mode switch is pressed twice in succession. A value indicating which mode switch has been pressed is written in the timer flag TMF. Ready flag READY: A flag that is set when the same mode switch as that previously operated is pressed and the switch is kept pressed for a predetermined time or more. FIG.

HS in FIG. 3 is a host selection mode switch,
It is used to specify the model of the host computer 6 connected to the tone generator module. Reference numeral 13 denotes a tone generator circuit for forming a tone signal. The sound system SP generates a tone signal generated by the tone generator 13 as a tone. The MIDI terminal M has an IN terminal MI for receiving an input signal from the outside, and an O terminal for outputting a signal to the outside.
It comprises a THRU terminal MT for outputting a signal received via the UT terminal MO and the IN terminal to the outside (see FIG. 3).
1, the output terminal of the sequencer 9 is connected to the IN terminal MI, and the input terminal of the sequencer 9 is connected to the OUT terminal MO.

The operation of this embodiment will be described below with reference to the flowcharts shown in FIGS. When the power of the sound source module device is turned on, the CPU 1 executes the processing of the main routine shown in FIG. First, the process proceeds to step S1, where control registers and flags in the RAM 4 are initialized. By this initialization, the mode register MODE
Is written with a value that does not correspond to any of the mode switches. Further, “0” is set as an initial value in the timer flag TMF and “0” is set in the ready flag READY as initial values. Next, proceeding to step S2, a panel processing routine whose flow is shown in FIGS. 5 to 7 is executed. This panel processing routine includes steps SA1 to SA17 corresponding to the operation of the GM mode switch K1 (FIG. 5), and steps SB1 to SB corresponding to the operation of the DO mode switch K2.
17 (FIG. 6) and the processing (FIG. 7) consisting of steps SC1 to SC17 corresponding to the operation of the CM mode switch K3. Where D
In the processing corresponding to the operation of the O mode switch K2 and the CM mode switch K3, the term "GM mode switch" in the processing corresponding to the GM mode switch K1 means "DO mode switch" and "CM mode switch".
The processing contents have been changed respectively. That is, each process corresponding to each mode switch has exactly the same contents except that the type of the target mode switch is different, and steps SBn and SCn corresponding to the DO mode switch K2 and the CM mode switch K3.
(N = 1 to 17) respectively correspond to steps SAn (n = 1 to 17) in the processing corresponding to the GM mode switch, and therefore, here, mainly steps SA1 to SA17
Will be described in detail. First, step SA1
The CPU 1 determines whether the GM mode switch K1 has changed from the OFF state to the ON state. If the user has not operated the mode switch, the result of this determination is "NO" and the flow advances to step SA6 to determine whether or not information corresponding to the GM mode is stored in the timer flag TMF. If the user has not operated the panel switch, the result of the determination in step SA6 is "NO" and the flow proceeds to step SA9, in which the CPU 1 determines whether or not the GM mode switch K1 has been turned off. When the user releases the pressing operation of the mode switch, the result of this determination is “YES”, and the process proceeds to Step SA10,
It is determined whether or not information for the GM mode is stored in the timer flag TMF. Here, as described later, it is determined whether or not the continuous push state has been released halfway. If the mode is simply set, “NO” is determined. If the user does not operate any of the mode switches, steps SB1, SB6, SB
The results of the determinations of 9, SC1, SC6 and SC9 are all "NO", and the panel processing routine ends. When the panel processing ends and returns to the main routine, step S3 is performed.
To execute a MIDI processing routine to transmit / receive a MIDI event, perform sound generation control based on the MIDI event, and the like. Next, the process proceeds to step S4, where a computer processing routine is executed to transmit and receive a MIDI signal between the computer host and the tone generator module. And
It returns to step S2 again. Thereafter, steps S2 to S4 are repeated.

On the other hand, when an interrupt signal is supplied from the timer 10 and an interrupt mask is not made at that time, the CPU 1 executes a timer interrupt routine shown in FIG. 10 to increment the time counter TC. The process of performing the interrupt mask will be described later.

When the user presses the GM mode switch K1, the CPU 1 detects an ON event indicating that the GM mode switch K1 has changed from the OFF state to the ON state. As a result, when proceeding to the panel processing routine via step S2 of the main routine, the result of the determination at step SA1 becomes "YES", and
Proceed to A2. Then, it is determined whether or not information corresponding to the GM mode is stored in the mode register MODE. If the result of this determination is "NO", then step SA
Proceeding to 14, it is determined whether the value of the ready flag READY is "1". If the result of this determination is "NO", it means that the GM mode has just been selected, and the process proceeds to step SA15, where information corresponding to the GM mode is set in the MODE register. Next, proceeding to step SA16, GM mode processing is executed, and this sound source module is
The following processing required to function as a sound source conforming to the M standard is performed. (1) Create a conversion table for converting a tone color number included in performance data into a tone color number corresponding to the GM standard. (2) Multi-parameter initial value setting processing, that is, environment setting for transmission and reception of a signal corresponding to a GM sound source when a MIDI terminal is connected. (3) Environment setting such as storing, reproducing, and editing data in the format of the GM sound source.

When the user performs the second GM mode switch K1
Is pressed, the CPU 1 detects an ON event of the GM mode switch K1. As a result, step S
The determination result of A1 becomes "YES", and step SA2
Proceed to. In this case, since the information corresponding to the GM mode is set in the mode register MODE (step SA15 described above), the result of the determination in step SA2 is “YE
S ", and the process proceeds to Step SA3. Next, step SA
When the process proceeds to 3, it is determined whether or not the ready flag READY is "1". Since the ready flag READY is cleared at first, the result of this determination is "NO" and the routine proceeds to the next step SA12, where the timer flag TMF is set to G.
The information corresponding to the M mode is set. Step SA1
At 3, a timer start routine is executed. When proceeding to the timer start routine, the timer counter TC is first cleared to zero (step S101). Next, the timer interrupt mask is released (step S10).
2). As a result, each time an interrupt signal is thereafter output from the timer 10, the CPU 1 executes a timer interrupt routine. When the timer start routine ends, the process returns to the main routine and proceeds to step SA6. In this case, the result of the determination in step SA6 becomes "YES" and the flow advances to the next step SA7 to determine whether or not the GM mode switch K1 has been continuously pressed for 2 seconds, that is, whether the timer counter TC
It is determined whether or not the value has been counted up for 2 seconds or more in terms of time.

Thereafter, while the user keeps pushing the GM mode switch K1, step SA of the panel processing routine is performed.
When the process proceeds to 1, the determination result is “NO”. Then, the process proceeds to Step SA6, the result of this determination is “YES”, and the process proceeds to Step SA7. If the user presses the GM mode switch within 2 seconds, the determination result is “NO”.

If the user keeps pressing the GM mode switch K1 for more than 2 seconds, the result of the determination in step SA7 is "YE
S ", the process proceeds to Step SA8, and among the switches on the front panel, L corresponding to the GM mode switch K1
ED4 is made to blink at regular intervals, and the process proceeds to a timer stop processing routine shown in FIG.
Is cleared to zero (step S201), and the timer interrupt mask is released (step S202). Also, “0” is written to the timer flag TMF, and the ready flag REA is written.
Write "1" to DY.

By the above processing, the ready flag RE
After ADY = "1", when the user presses the GM mode button again (the third press), step SA1,
The result of determination in SA2 becomes "YES", and step SA
Proceed to 3. Since the value of the ready flag READY is “1”, the result of the determination in step SA3 is “YE
S ", and proceeds to the next step SA4. In step SA4, a bulk dump processing routine relating to data communication with the external device is executed. In this bulk dump processing routine, the following processing is performed. (1) Parameter status of a sound source currently emulated to an external device through the host computer 6 and the MIDI interface 8 (SYSTEM, MULTI C
OMMON,. . . ) Is output in the exclusive message format. (2) The LED corresponding to the GM mode switch is changed from flashing at regular intervals to blinking at irregular intervals, and is brought into a display state meaning that a bulk dump process is being performed. (3) Before starting the transmission process, the internal setting information is temporarily saved in an external device such as MIDI or a computer. After the transmission processing is completed, the internal setting state is returned to the saved state, and the LED is returned to the lighting state.

When the user performs the second GM mode switch K1
If the button is pressed and the hand is released within 2 seconds thereafter, the process proceeds to step SA6 via step SA1, the result of this determination is "YES", and the process proceeds to step SA7. Here, since the determination result is “NO”, the process proceeds to Step SA9.
The result of the determination in steps SA9 and SA10 is "YES", the flow proceeds to step SA11, the timer flag TMF is cleared to zero, and the above-described timer stop routine is executed. Then, the processing corresponding to the next DO mode switch and the processing corresponding to the CM mode switch are performed, and the process returns to the main routine.

If another mode switch, for example, a DO mode switch K2 is pressed while the ready flag READY = "1", the process proceeds to step SB1.
The result of this determination is "YES". Next step SB2
Then, it is determined whether or not information corresponding to the DO mode is stored in the mode register MODE. Since information corresponding to the GM mode is stored in the mode register MODE, the result of this determination is "NO", and the routine proceeds to step SB14. Then, it is determined whether or not the value of the ready flag READY is “1”. The result of this determination is “Y
ES ”, the process proceeds to Step SB17, and the ready flag READY is set to“ 0 ”.
The LED corresponding to the mode switch is turned on. As described above, when a switch different from the mode switch previously pressed is pressed for the second time, the READY state is canceled. At this time, the ready flag READY = "0", and a value corresponding to the GM mode is set in the mode register MODE.

The present invention is applicable not only to the panel switch of the electronic musical instrument but also to other electronic devices.

[0017]

As described above, according to the present invention, when there is no room to increase the number of switches, the user can press the switch according to the lit LED without having to remember the correspondence between the switch and the function. There is an effect that the property rises. Further, since one switch corresponds to a plurality of functions, it is possible to operate more functions in a limited space.
