[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic device such as an electronic musical instrument, and more particularly to an electronic device that allows a user to set a desired function with a function switch.

[0002]

[Prior art]

 The electronic device has many types of functions compared to the area of the panel surface of the electronic device, and it may be difficult to provide the number of function switches corresponding to those functions. In such a case, conventionally, the following two types of function setting units for electronic devices have been used. <First type> An electronic device configured to set a function corresponding to a combination of two types of function switches when they are pressed. <Second type> An electronic device that sets different functions depending on whether a certain function switch is pressed for a short time or when it is pressed for a long time.

[0003]

[Problems to be solved by the device]

 By the way, the above-mentioned electronic device of the first type has a drawback that it is difficult to push the switches when the distance between the two switches corresponding to the desired function is large. In addition, the user must remember the combination of switches, such as which switch to press and which switch to operate the desired function, which poses a problem that the user's operational burden is heavy. . In addition, in the second type of electronic device described above, in order to prevent erroneous operation by the user, the function set when the switch is pressed for a short time and the function set when the switch is pressed for a long time are set. There was a constraint that it had to be related to the function being performed. The present invention has been made under such a background, and an electronic device with excellent operability in which many functions can be instructed by one switch and the user can easily learn how to operate the switch. An object is to provide a device function setting device.

[0004]

[Means for Solving the Problems]

 A function setting device for an electronic device according to the present invention is provided on a panel of the electronic device, a function switch that is turned on / off by a user's operation, and a lighting means provided corresponding to the function switch. 1) When the function switch is pressed for the first time, the first processing corresponding to the function switch is performed and the lighting means is set to the first lighting state, and (2) the first processing state is set. When the function switch is pressed again for a predetermined time or more, the lighting means is set to the second lighting state, and (3) the function switch is pressed again in the second lighting state. And processing control means for performing the second processing different from the first processing and for setting the lighting means in the third lighting state.

[0005]

[Action]

 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 is brought into the first lighting state. When the same function switch is pressed for a predetermined time or longer while the first processing state is set, the lighting state of the lighting means becomes the second lighting state, and when the same function switch is pressed again in this state, A second process different from the first process performed is executed. Since the method of operating the function switch provided in this panel can be determined by the lighting mode of the lighting means, the operability as a function setting device of the electronic device is improved.

【Example】

 An embodiment 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 device, and FIG. 3 is a rear view showing a rear panel. This sound source module device emulates a sound source corresponding to three kinds of standards, a GM (GM-L1) standard, a DO (disk orchestra) standard and a CM (computer music) standard. In FIG. 1, reference numeral 1 denotes a CPU (central processing unit), which controls the entire sound source module device. Reference numeral 11 denotes a ROM (Read Only Memory), which stores a control program executed by the CPU 1 and various control data. 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 arranged on the front panel as shown in FIG. Each of the mode switches K1 to K3 is a self-reset type push button type switch, and these mode switches K1 to K3 are used to instruct the CPU 1 to emulate the GM standard, DO standard and CM standard described above. It is provided as an operator. The 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 each of these LEDs is attached to the front panel together with each of the mode switches K1, K2 and K3. The CPU 1 controls the lighting of each LED that constitutes the LED group 4 via the LED interface 5. Reference numeral 12 is a RAM (random access memory), and each storage area of the RAM 12 is used as a register and flags for storing various control information. The main ones of these registers and flags are listed below. Mode register MODE: This register is updated when any one of the mode switches K1, K2, and K3 is turned on, and the value corresponding to the mode switch turned on is written. Timer flag TMF: This flag is updated when the same mode switch is pressed twice in succession. A value indicating which mode switch is pressed is written in the timer flag TMF. Ready flag READY: This flag is set when the same mode switch as the one operated last time is pressed and the switch is kept pressed for a certain time or longer. In FIG. 1, reference numeral 10 is a timer, which outputs a timer interrupt signal to the CPU 1 at predetermined intervals. Reference numeral 6 denotes a computer, which is connected to the host interface 7 of this sound source module through the host terminal HJ shown in FIG. HS in FIG. 3 is a host selection mode switch, and is used to specify the model of the host computer 6 connected to the sound source module. Reference numeral 13 is a tone generator circuit, which forms a tone signal. The sound system SP produces the tone signal formed by the sound source circuit 13 as a tone. The MIDI terminal M includes an IN terminal MI for receiving an input signal from the outside, an OUT terminal MO for outputting a signal to the outside, and a THRU terminal MT for outputting a signal received via the IN terminal to the outside ( (See FIG. 3). In the configuration of FIG. 1, the output end of the sequencer 9 is connected to the IN terminal MI and the input end of the sequencer 9 is connected to the OUT terminal M O, and transmission / reception is performed via the MIDI interface 8.

The operation of this embodiment will be described below with reference to the flow charts shown in FIGS. When the power source of the sound source module device is turned on, the CPU 1 executes the processing of the main routine shown in FIG. First, in step S1, each control register and flags in the RAM 4 are initialized. By this initialization, a value that does not correspond to any mode switch is written in the mode register MODE. Also, the timer flag TMF is set to "0" and the ready flag READY is set to "0" as initial values. Next, in step S2, the 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), steps SB1 to SB17 corresponding to the operation of the DO mode switch K2 (FIG. 6), In addition, the processing (FIG. 7) including steps SC1 to SC17 corresponding to the operation of the CM mode switch K3 is sequentially organized. Here, in each process corresponding to the operation of the DO mode switch K2 and the CM mode switch K3, the “GM mode switch” in the process corresponding to the GM mode switch K1 is the “DO mode switch” and the “CM mode”. The processing contents are changed to "mode switch". That is, each process corresponding to each of these mode switches has exactly the same contents except for the type of the target mode switch, and the steps corresponding to the DO mode switch K2 and the CM mode switch K3. Since SBn and SCn (n = 1 to 17) respectively correspond to step SAn (n = 1 to 17) in the processing corresponding to the GM mode switch, here, the processing mainly including steps SA1 to SA17 will be described. Detailed description. First, in 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 operation proceeds to step SA6, where it is determined whether or not the information corresponding to the GM mode is stored in the timer flag TMF. If the user has not operated the panel switch, the determination result of step SA6 is "NO", and the process proceeds to step SA9, and the CPU 1 determines whether or not the GM mode switch K1 is in the OFF state. When the user releases the pressing operation of the mode switch, the result of this determination is "YES", the flow proceeds to step SA10, and it is determined whether or not the information for the GM mode is stored in the timer flag TMF. Here, as will be described later, it is determined whether or not the continuously pressed state is canceled halfway. In the case of simply setting the mode, "NO" is determined. If the user has not operated any of the mode switches, the judgment results of steps SB1, SB6, SB9, SC1, SC6 and SC9 are all "NO", and the panel processing routine is ended. When the panel processing ends and returns to the main routine, the process proceeds to step S3 to execute the MIDI processing routine to perform transmission / reception of MIDI events, sound generation control based on MIDI events, and the like. Next, in step S4, a computer processing routine is executed to transmit / receive MIDI signals between the computer / host and the sound source module. Then, the process returns to step S2 again. After that, steps S2 to S4 are repeated.

On the other hand, when the interrupt signal is supplied from the timer 10 and the interrupt mask is not made at that time, the CPU 1 executes the timer interrupt routine shown in FIG. 10 to increment the time counter TC. The process of executing 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 K 1 has changed from the OFF state to the ON state. As a result, when the process proceeds to the panel processing routine via step S2 of the main routine, the determination result of step SA1 becomes "YES" and the process proceeds to step SA2. Then, it is determined whether or not the information corresponding to the GM mode is stored in the mode register MODE. If the result of this determination is "NO", the flow proceeds to step SA14 and it is determined whether or not the value of the ready flag READY is "1". If the result of this determination is "NO", it means that the GM mode has simply been selected, so the routine proceeds to step SA15, where information corresponding to the GM mode is set in the MODE register. Next, in step SA16, GM mode processing is executed, and the following processing necessary for causing this sound source module to function as a sound source compatible with the GM standard is performed. (1) A conversion table for converting the tone color numbers included in the performance data into the tone color numbers corresponding to the GM standard is created. (2) Initial setting process of multi-parameters, that is, environment setting for signal transmission / reception corresponding to GM sound source when MIDI terminal is connected. (3) To set environment such as storing, playing, and editing data in the GM sound source format.

When the user presses the GM mode switch K1 for the second time, the CPU 1 detects the ON event of the GM mode switch K1. As a result, the determination result of step SA1 becomes "YES", and the process proceeds to step SA2. In this case, since information corresponding to the GM mode is set in the mode register MODE (step SA15 described above), the determination result of step SA2 becomes "YES", and the process proceeds to step SA3. Next, in step SA3, it is determined whether or not the ready flag READY is "1". Since the ready flag READY is initially cleared, the result of this determination is "NO" and the routine proceeds to the next step SA12, where information corresponding to the GM mode is set in the timer flag TMF. In step SA13, a timer start routine is executed. When proceeding to this timer start routine, the timer counter TC is first cleared to zero (step S101). Next, the timer interrupt mask is released (step S102). As a result, the CPU 1 executes the timer interrupt routine each time an interrupt signal is subsequently output from the timer 10. When the timer start routine ends, the process returns to the main routine and proceeds to step SA6. In this case, the determination result of step SA6 becomes "YES", and the process proceeds to the next step SA7, and it is determined whether or not 2 seconds have elapsed since the GM mode switch K1 was continuously pressed, that is, the value of the timer counter TC indicates the time. It is determined whether or not it has been counted up for 2 seconds or more.

After that, while the user continues to press the GM mode switch K1, when the process proceeds to step SA1 of the panel processing routine, the determination result is “NO”. Then, the process proceeds to step SA6, the determination result is "YES", and the process proceeds to step SA7. If the user presses the GM mode switch for less than 2 seconds, the judgment result is "NO".

When the user continues to press the GM mode switch K1 for 2 seconds or more, the result of the determination in step SA7 is “YES” and the process proceeds to step SA8, and corresponds to the GM mode switch K1 of the switches on the front panel. The blinking LEDs 4 are blinked at equal intervals, the process proceeds to the timer stop processing routine shown in the flow chart of FIG. 9, the timer counter TC is cleared to zero (step S201), and the timer interrupt mask is released (step S202). Further, "0" is written in the timer flag TMF and "1" is written in the ready flag READY.

After the ready flag READY = "1" is set by the above-described processing, when the user presses the GM mode button again (third press), the determination results of steps SA1 and SA2 are "YES". Then, the process proceeds to step SA3. Since the value of the ready flag READY is "1", the determination result of step SA3 is "YES", and the process proceeds to the next step SA4. When the processing proceeds to step SA4, a bulk dump processing routine relating to data communication with an external device is executed. In this bulk dump processing routine, the following processing is performed. (1) Output of the parameter status (SYSTEM, MUL TI COMMON, ...) Of the sound source currently emulated to the external device through the host computer 6 and the MIDI interface 8 in the exclusive message format. (2) The LED corresponding to the GM mode switch is changed from blinking at regular intervals to blinking at irregular intervals so that the display state means that the bulk dump process is in progress. (3) The internal setting information is temporarily saved in an external device such as MIDI or a computer before starting the transmission process. After the transmission process is completed, the internal setting state is returned to the saved state, and the LED is turned on again.

When the user presses the GM mode switch K1 for the second time and then releases the hand within 2 seconds, the process proceeds to step SA6 via step SA1 and the result of this determination becomes “YES” and step SA7 Proceed to. In this case, the determination result is "NO", so the flow proceeds to step SA9. The determination result of steps SA9 and SA10 is "YES", and the process proceeds to step SA11 to clear the timer flag TMF to zero and execute the above-mentioned timer stop routine. Then, the process corresponding to the next DO mode switch and the process corresponding to the CM mode switch are performed, and the process returns to the main routine.

When another mode switch, for example, the DO mode switch K2 is pressed while the ready flag READY = “1”, the process proceeds to step SB1 and the determination result is “YES”. In the next step SB2, it is determined whether or not the information corresponding to the DO mode is stored in the mode register MOD E. Since information corresponding to the GM mode is now 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 REA DY is "1". The result of this determination is "YES", the flow proceeds to step SB17, the ready flag READY is set to "0", and the LED corresponding to the blinking GM mode switch is turned on. In this way, when a switch different from the previously pressed mode switch is pressed for the second time, the READY state is canceled. At this time, the ready flag READY = "0", and the value corresponding to the GM mode is set in the mode register MODE.

The present invention can be applied not only to the panel switch of the electronic musical instrument but also to other electronic devices.
