[0001]
[Field of the Invention]
The present invention relates to a performance information recording apparatus capable of recording a performance event using a function called “grid recording function”.
[0002]
[Prior art]
Conventionally, a performance information recording apparatus that records performance information defined by a performance event and a performance timing of the performance event is known. For example, in Non-Patent Document 1 below, performance information is recorded in a recording target part using a function called “grid recording function”.
[0003]
That is, in the performance information recording apparatus of Non-Patent Document 1 below, 16 grid REC switches are provided, for example, two measures of a performance part are set as “recording target patterns”, and each grid REC switch is set to 2 Each is associated with the beat timing (eighth note) of the measure. The user sets a performance event for recording at the time of grid recording. Here, the performance event includes parameters such as pitch (hereinafter also referred to as “note number”), gate time, velocity, and the like. For example, tempo data other than those exemplified may be included in the parameters. In particular, in the rhythm part, the pitch (note number) is a parameter that defines the type of musical instrument.
[0004]
During the operation of the grid recording function, the pressing of the grid recording switch is accepted while reproducing the recording target pattern. When any grid REC switch is pressed, the recording performance event set at that time is recorded in the recording target pattern. The performance timing of the performance event is determined by which grid REC switch is pressed. Therefore, the performance event is recorded at a position corresponding to the performance timing corresponding to the pressed grid REC switch in the recording target pattern. .
[0005]
The performance event for recording can be set with a dial operator provided separately. In grid recording, a parameter such as pitch is set to a desired value, and then a desired grid recording switch is pressed. The procedure is taken.

[0014]
FIG. 1 is a block diagram showing the overall configuration of a performance information recording apparatus according to an embodiment of the present invention. The performance information recording apparatus is configured as an electronic musical instrument such as a rhythm machine, for example.
[0015]

To sound.
[0018]
FIG. 2 is a diagram illustrating a configuration of the operation panel of the apparatus. The operation panel of this apparatus includes a display screen 30 such as a liquid crystal display, a dial type parameter operator 41 (41A, 41B, 41C), a pitch input switch 43 (5), a grid REC switch 45 (8), and each sound. LED 42 (5) corresponding to the high input switch 43, LED 44 (8) corresponding to each grid REC switch 45, scan switch (SCAN) 46, and pad switches 47 and 48 (PAD1, 2) Is done. The display screen 30 is displayed on the display unit 19.
[0019]
The parameter operator 41, the LEDs 42 and 44, and the various switches 43, 45, 46, 47, and 48 are disposed in the operation unit 20. The LEDs 42 and 44 are disposed above the corresponding pitch input switches 43 and grid REC switches 45, respectively. In the following, when the eight grid REC switches 45 or the corresponding LEDs 44 are described separately, serial numbers are assigned, and the grid REC switches 45 (1), 45 (8), LEDs 44 (1), 44 Write as (8).
[0020]
In the present apparatus, performance information can be recorded using a function called “grid recording function”. In Grid Rec, a predetermined length (for example, four bars) of a performance part to be recorded is set as a “recording target pattern (performance information)”, and a grid recording event is recorded as a performance event by pressing the grid recording switch 45. Record in the pattern.
[0021]
The display screen 30 displays grid REC event parameters and their values. Hereinafter, the grid REC event is abbreviated as “GREC event”, and the parameter of the Grid REC event is abbreviated as “GREC event parameter”. The GREC event is a performance event for recording recorded in the recording target pattern when any one of the grid REC switches 45 is pressed next time. The GREC event parameter is stored, for example, in a GREC event buffer in the RAM 11.
[0022]
The GREC event parameter includes “note number” indicating the pitch, “gate time” indicating the sound duration, and “velocity” indicating the sound volume. In normal manual setting, “note number”, “gate time”, and “velocity” can be individually set by the parameter operators 41A, 41B, and 41C, and the display units 31, 32, and 33 in the display screen 30 are set. The current setting value is displayed on the screen. In the example of the figure, they are “C3”, “80%”, and “103”, respectively.
[0023]
The user can arbitrarily select one of all the pitches that can be set as pitch data during the GREC event using the parameter operator 41A, and a new note number in order of the pitch for each operation. Can be called and entered. In the present embodiment, the pitches that can be input are 128 (0 to 127). Note that when creating a rhythm part, the pitch (note number) defines the percussion instrument type, so the note number setting corresponds to the selection of the percussion instrument type.
[0024]
The pitch input switch 43 and the grid REC switch 45 are arranged to imitate the black key and white key of the keyboard, respectively. It can be operated with. The grid REC switch 45 is also used for inputting a GREC event in the grid REC function.
[0025]
In the grid recording function, when creating a recording target pattern that is a performance pattern for four bars of a certain performance part, first two bars or two latter bars of the recording target pattern are first selected. Each grid REC switch 45 is pre-assigned with a “performance timing T” that defines in which time position of the recording target pattern the current GREC event is to be recorded. The eight grid REC switches 45 respectively correspond to the selected two-measure beat timing (quarter note), and data indicating the corresponding beat timing corresponds to the performance timing T.
[0026]
Actually, as will be described later, each GREC event is associated with timing data TD indicating the time interval (counter value from the beginning) from the position of the first beat of the second measure selected in each recording target pattern. The timing data TD is defined by the performance timing T. Note that the timing data TD may not be used as long as it is data that can specify the performance timing of the recorded performance event. For example, the performance timing may be specified by the duration from the immediately preceding performance event. Good.
[0027]
The LEDs 42 and 44 are turned on in response to operations of the corresponding pitch input switch 43 and grid REC switch 45, respectively. In the grid recording function, the LED 44 is turned on to indicate the presence of a performance event recorded in the recording target pattern for the note number currently set as the GREC event parameter. The LED 44 also performs a blinking operation to indicate the current reproduction position when the recording target pattern is continuously reproduced in the grid recording function.
[0028]
The scan switch 46 is provided separately from the parameter operator 41. The scan switch 46 is used to change the note number among the current GREC event parameters. Although details will be described later, by pressing the scan switch 46, it is possible to change to a desired note number selected from the created “note number list (predetermined pitch group)”.
[0029]
Further, in the present embodiment, “real time recording” can be performed by operating the pad switches 47 and 48 even during the operation of the “grid recording function”. In real-time recording by the pad switches 47 and 48, a “real-time recording event” is recorded in the recording target pattern as a performance event.
[0030]
The grid REC switch 45 can record a GREC event only at the performance timing T assigned to the grid REC switch 45, but the pad switches 47 and 48 record a real-time REC event at the performance timing T according to the operation timing. can do. Detailed processing will be described later. Hereinafter, “real-time REC event” is abbreviated as “RTREC event”, and “real-time REC event parameter” is abbreviated as “RTREC event parameter”.
[0031]
The operation state (ON / OFF, operation timing, pressed time, and pressing strength) of the pad switches 47 and 48 is detected by the detection circuit 16. Also, an arbitrary note number can be assigned and set to each of the pad switches 47 and 48, and the set note number is one of the parameters of the RTREC event recorded by the operation of each pad switch 47 and 48. It will be a note number.
[0032]
That is, in the real-time recording by the pad switches 47 and 48, the recorded RTREC event parameter is not the GREC event parameter set at the time of operation. In other words, the pitch (note number) assigned to each of the pad switches 47 and 48 at that time is adopted and set. The gate time is set based on the detected pressing duration and the velocity is set based on the detected pressing strength.
[0033]
3 to 6 are diagrams showing an example of performance data and the state of the operation panel when the grid recording function is operated.
[0034]
Each figure (a) is a conceptual diagram of a part of performance data for a recording target pattern (four measures). This performance data is stored in the RAM 11, for example. One pattern to be recorded has 16 beat timings in four time signatures. In the example of FIG. 3A, a performance event having note numbers “C3”, “D3”, and “G3” is the first measure. Recorded on the first beat.
[0035]
Each figure (b) has shown the lighting state of LED44 corresponding to the grid REC switch 45, and in each figure (b), it shows that a black circle is a lighting state. If there is a beat timing that matches the note number of the currently set GREC event parameter among the note numbers of the performance event recorded in the two measures selected in the recording target pattern, Corresponding LEDs 44 are individually lit. For example, if the note number is “D3” in the current GREC event parameter setting, in the example of FIG. 3A, as shown in FIG. 3B, the grid REC switches 45 (1), 45 ( Only the LEDs 44 (1) and 44 (5) corresponding to 5) are lit. The lighting state of the LED 44 can be changed not only by the operation of the parameter operator 41A but also by the operation of the scan switch 46 and the pad switches 47 and 48, as will be described later.
[0036]
When the grid recording function is operated, for example, the first two bars of the recording target pattern are selected, and the GREC event parameter is set by the parameter operator 41. Then, when a desired grid REC switch 45 is pressed in this state, a GREC event is recorded as a performance event at a position corresponding to the beat timing corresponding to the pressed grid REC switch 45 in the recording target pattern. . Each time the user inputs a GREC event, the parameter operator 41 changes the GREC event parameter as necessary, and the pressing operation is repeated. By performing the same operation for the last two measures, one performance pattern for the performance part is completed.
[0037]
Next, the scanning process and the real-time recording process in parallel with the grid recording function operation will be described with reference to FIGS.
[0038]
FIG. 7 is a diagram showing a flowchart of main processing in the present embodiment. This process is started when the start of the grid recording function is instructed. At the start of execution, a counter for measuring the progress of the recording target pattern is reset and a real-time recording process of FIG. 9 described later is also started. . In this process, the user sets a recording target pattern and selects two bars in the first half or the second half. Note that switching between the first two bars and the second two bars is omitted in the flowchart of FIG. 7, but can be performed at any time by a switching operator (not shown) of the operation unit 20 during this processing. As described above, the pattern to be recorded is repeatedly reproduced, and the current reproduction position can be known by blinking the LED in accordance with the progress.
[0039]
First, it is determined whether or not there has been an instruction to change the parameter operator 41, that is, a GREC event parameter change instruction (step S701). If there is no change instruction, the process proceeds to step S704. In accordance with the change instruction, the GREC event parameter is changed (step S702). That is, new values are set for the note number, gate time, and velocity, respectively, according to the operation of the parameter operators 41A, 41B, and 41C, and the changed GREC event parameters are stored in the GREC event buffer.
[0040]
Next, various displays are changed in accordance with the newly set GREC event parameter value (step S703). That is, the parameter display on the display screen 30 (FIG. 2) and the lighting display of the LED 44 are changed. For example, when the note number is changed, the changed note number is displayed on the display unit 31, and only the performance event having the changed note number is read in the recording target pattern, and the read performance event is read. Only the LED 44 (corresponding to the position of the read performance event) corresponding to the timing data TD associated with is lit (see FIG. 3). Thereafter, the process proceeds to step S704.
[0041]
In step S704, whether or not a GREC event recording instruction has been detected is determined based on which one (or more) of the eight grid REC switches 45 has been pressed. As a result of the determination, if a GREC event recording instruction is not detected, the process proceeds to step S708. If a GREC event recording instruction is detected, a recording performance timing T (R) in GREC event recording is determined (step S705). ). Here, the performance timing T assigned to the pressed grid REC switch 45 is determined as the recording performance timing T (R).
[0042]
Next, a performance event writing process is performed (step S706). That is, the currently set GREC event is additionally written as a performance event at a position corresponding to the recording performance timing T (R) in the recording target pattern. Here, if a performance event having the same note number has already been recorded at the same position to be written, the performance event that has already been recorded is erased without writing. Therefore, when the same grid number switch 45 is repeatedly pressed at the same note number, recording and erasing of the performance event of that note number are repeated alternately. Next, the LED display is updated (step S707).
[0043]
Here, the process of said step S704-S707 is illustrated concretely. For example, when the performance data of the pattern to be recorded is set as shown in FIG. 4A and the note number of the GREC event parameter is set to “G3”, the grid REC switch 45 (8) is pressed. Then, as shown in FIG. 5A, a performance event of note number “G3” is added at the position of the eighth beat of the recording target pattern. At the same time, the display of the LED 44 changes from the state shown in FIG. 4B to the state shown in FIG. 5B, and the LED 44 (8) is newly lit. At this time, since the GREC event parameter is not changed, the display in the display screen 30 is not changed.
[0044]
Next, in step S708, it is determined whether or not an on-operation of the scan switch 46 has been detected. If an on-operation has been detected, a scan process shown in FIG. On the other hand, if the on operation is not detected, the process proceeds to step S710 without executing the scan process.
[0045]
In step S710, it is determined whether or not a stop instruction for the grid recording function is detected. If no stop instruction is detected, the process returns to step S701. If a stop instruction is detected, the real-time recording process shown in FIG. Is stopped, and writing to the pattern to be recorded is terminated (step S711), and this process is terminated.
[0046]
FIG. 8 is a diagram showing a flowchart of the scanning process executed in step S709 of FIG.
[0047]
First, the pitch (note number) is extracted from the parameters of all performance events in the recording target pattern, and a note number list is created (step S801). That is, all the pitches in the performance data for the four measures of the pattern to be recorded are stored in order of pitches and created as a list. This note number list is stored in the RAM 11, for example. Note that the range for extracting the note numbers listed in the note number list need not be limited to the pattern to be recorded (four measures) as in the present embodiment. Alternatively, on the contrary, only the first two bars or the second half of the selected bar may be set as the range. It is desirable that the extraction range can be changed each time.
[0048]
Next, a note number next higher than the note number currently set as the GREC event parameter is selected from the note number list (step S802), and the selected note number is stored in the GREC event buffer (step S803). . That is, the selected note number is newly set as the note number of the GREC event parameter. Next, various displays are changed in accordance with the newly set note number value (step S804), and this process ends.
[0049]
This processing will be described in detail with reference to FIGS. 3 and 4. For example, the performance data of the pattern to be recorded is now set as shown in FIG. 3A (there is no performance event in the second two bars). It is assumed that the note number in the GREC event parameter is set to “D3”. When the scan switch 46 is pressed once, in the step S801, three types of note numbers “C3”, “D3”, and “G3” are extracted from all performance events in the recording target pattern, and these are used as notes. A number list is created.
[0050]
In step S802, “G3” is selected as the next highest note number with respect to “D3” which is the note number currently set in the GREC event parameter. If there is no next higher note number, the lowest note number is selected. If there is no note number different from the note number currently set in the GREC event parameter in the note number list, the same note number is selected.
[0051]
In step S803, the selected “G3” becomes a new note number in the GREC event parameter instead of the original “D3”. At this time, the gate time and velocity parameters are not changed. Note that the priority of selection of note numbers is the next highest note number in the pitch order, but is not limited to this. For example, the next lowest note number may be selected. Alternatively, the user may select a desired note number from the note number list. In that case, the candidate note number may be read each time the scan switch 46 is pressed.
[0052]
In step S804, the display of the LED 44 and the display screen 30 is changed. Note that the performance data itself of the pattern to be recorded does not change (FIG. 4A). That is, since the note number in the GREC event parameter has been changed to “G3”, “G3” is displayed on the display unit 31 of the display screen 30 (not shown), and “G3” is recorded for the LED 44. The LEDs 44 (1) to 44 (4) are lit up corresponding to the position of the performance event being played (FIG. 4B).
[0053]
After the scan process, grid REC can be performed with the changed GREC event parameter, and the changed GREC event becomes a performance event recorded when the grid REC switch 45 is pressed next time.
[0054]
FIG. 9 is a flowchart of the real-time REC process. This processing is executed at a predetermined interrupt interval during execution of the main processing in FIG. The predetermined interrupt interval is set to a time interval finer than the cycle of the beat timing (quarter note in the present embodiment) set in the grid wreck, and is executed 48 times per quarter note, for example. In this processing, it is assumed that a default note number or a desired note number is assigned to each pad switch 47, 48 by the user.
[0055]
First, based on the time of the counter, it is determined whether or not a performance event to be sounded at this performance timing is recorded in the recording target pattern (step S901), and if recorded, it is recorded. The performance event is read and sounded (step S902), and the process proceeds to step S903. On the other hand, if the performance event to be sounded is not recorded, the process proceeds to step S903 without sounding. Since the contents of the recording target pattern change from time to time due to grid recording or real-time recording, the latest content is always the reproduction target.
[0056]
In step S903, whether or not an RTREC event recording instruction has been detected is determined based on whether or not any of the pad switches 47 and 48 has been operated. Note that the operations of the pad switches 47 and 48 are detected independently, and there may be overlap. If the RTREC event recording instruction is not detected as a result of the determination, the process proceeds to step S907. If the RTREC event recording instruction is detected, the recording performance timing T (R) in the RTREC event recording is determined (step S904). ). Here, the performance timing T (R) for recording the RTREC event is determined in accordance with the operation timing of the pressed pad switches 47 and 48. Specifically, the performance timing indicated by the current counter value is determined as the recording performance timing T (R).
[0057]
Next, a performance event writing process is performed (step S905). That is, the RTREC event is additionally written as a performance event at a position corresponding to the recording performance timing T (R) in the recording target pattern. Here, as described above, for the RTREC event parameter, the pitch (note number) assigned to the operated pad switches 47 and 48 is set, but the gate time and velocity are detected respectively. It is set based on the pressing duration and the detected pressing strength. Therefore, even during grid recording, the user can perform a desired event of a desired sound length and volume on a note number preset in the pad switches 47 and 48 within a resolution range of the interrupt interval. Can be recorded in position.
[0058]
Here, the time interval of the interrupt processing is fine, and in reality, it rarely overlaps with existing performance events, but in real-time recording, it is often desirable to input performance events at an arbitrary timing, so I will try to write Only when the performance event of the same note number has already been recorded at the same position, the RTREC event to be newly recorded is ignored, that is, not written, and is written in all other cases. If the RTREC event to be newly recorded and the existing performance event have very close performance timing (for example, a shift in the number of interrupt processing cycles), the input at the same timing is performed according to the concept of quantization. It may be determined that there has been, and the existing performance events may be erased uniformly.
[0059]
Next, display etc. are updated (step S906). Here, not only the display of the LED 44 but also the contents of the GREC event parameter and its display are updated. That is, for the GREC event parameter, the note number assigned to the operated pad switches 47 and 48 is newly set as the note number. Then, the changed note number is displayed on the display unit 31 of the display screen 30. However, the gate time and velocity are not changed, and the value and display are maintained as they are. Note that the gate time and velocity in the GREC event parameter are not used for recording in real time recording. Note that it may be configured so that the note number is not updated, that is, the GREC event parameter is not changed by the operation of the pad switches 47 and 48.
[0060]
Regarding the display of the LED 44, only the performance event having the note number assigned to the operated pad switch 47, 48 in the pattern to be recorded is read, and the timing data associated with the read performance event. Only the LED 44 corresponding to TD is lit. Note that the performance event recorded in the real-time recording may not match the beat timing due to the interrupt processing interval. In this case, the LED 44 corresponding to the beat timing closest to the performance event. To be lit.
[0061]
The processing of steps S903 to S906 will be specifically exemplified. For example, if the performance data of the recording target pattern is set as shown in FIG. 3A, the note number of the GREC event parameter is set to “D3”, and the note number is set to the pad switch 47. When “G3” is assigned, it is assumed that the pad switch 47 is pressed at a timing close to the timing of the sixth beat. Then, as shown in FIG. 6A, a performance event of note number “G3” is added to the corresponding position in the vicinity of the position of the sixth beat of the recording target pattern. Note that the performance event “G3” is not added at the position of the sixth beat, but strictly at the timing close to the sixth beat (the timing indicated by the counter value when the pad switch 47 is pressed). In the drawing (FIG. 6A), the timing is shown at the timing of the sixth beat for easy viewing.
[0062]
At the same time, the display of the LED 44 changes from the state shown in FIG. 3B to the state shown in FIG. 6B, and the LEDs 44 (1) to (4) and (6) are turned on. At this time, the changed note number is displayed on the display unit 31.
[0063]
Returning to FIG. 9, next, in step S907, the value of the counter is increased, the performance of the pattern to be recorded is advanced, and this processing is terminated. The counter counts the length of the pattern to be recorded (for four bars), and when it reaches the end of the four bars, resets the value and restarts counting from the beginning of the four bars.
[0064]
Thus, when the grid REC and the real-time REC are compared, it can be said that the method of determining the timing data TD associated with the performance event to be recorded is different. That is, the timing data TD is determined by which grid REC switch 45 is pressed in the grid recording, and is determined by the performance progress timing (counter value) at the time when the pad switches 47 and 48 are pressed in the real-time recording.
[0065]
According to the present embodiment, the note number of the GREC event parameter is changed to the next highest note number in the note number list every time the scan switch 46 is pressed during the operation of the grid recording function. If you want to re-enter the same pitch that you previously input in the same recording target pattern, you can quickly and easily set the desired note number as a GREC event parameter without operating the parameter operator 41A step by step. Can be redone. Therefore, it is possible to easily input the pitches input in the past and efficiently record the performance event with a simple operation.
[0066]
Each time the scan switch 46 is pressed, the note number next to the current set value is sequentially selected from the note number list, so that it is easy to understand intuitively and the note number can be easily set.
[0067]
Also according to the present embodiment, since the inputs from the pad switches 47 and 48 are accepted and real-time recording is possible even during the operation of the grid recording function, the performance can be performed at a performance timing finer than the minimum resolution determined by the grid recording switch 45. Even when an event is desired to be recorded, a performance event can be easily input at a desired performance timing without requiring a complicated operation such as changing to a mode for real-time recording. Therefore, it is possible to simultaneously use both a normal grid recording operation and a real-time recording operation, and a variety of intended performance patterns can be created with a simple operation.
[0068]
In addition, since a desired note number can be assigned to the pad switches 47 and 48, the desired pitch can be recorded according to the operation timing simply by operating the pad switches 47 and 48, which is easy to use. .
[0069]
Further, among the RTREC event parameters, the gate time and velocity are set based on the detection operation state of the pad switches 47 and 48, so that the user can input a performance event with a more realistic feeling. .
[0070]
Note that the note number list may be created arbitrarily by the user by collecting, for example, note numbers that are considered to be frequently used, or the note number list created by extracting from the recording target pattern You may be able to add note numbers. In this way, in particular, it is possible to facilitate the input of note numbers that are frequently used, and to record performance events more efficiently.
[0071]
In the scan process, only the note number in the GREC event parameter is updated in step S803 in FIG. 8, but the present invention is not limited to this, and the gate time and / or velocity may be updated. Good. In this case, for example, the gate time and velocity of a performance event having as a parameter the note number selected from the note number list in the recording target pattern may be adopted as the update parameter.
[0072]
The LEDs 42 and 44, the pitch input switch 43, and the grid REC switch 45 are not limited to the exemplified numbers. In particular, the LED 44 and the grid REC switch 45 are arranged in four bars according to the pattern length to be recorded. It is desirable to double the number of arrangements so as to correspond. The recording target pattern is four bars of the performance part to be recorded, but is not limited to the four bar length.
[0073]
Note that the predetermined interrupt interval, which is the execution interval of the real-time recording process, may be the same as the beat timing of the recording target pattern. In that case, the performance timing always matches between the RTREC event to be newly recorded and the existing performance event. Therefore, in step S905 of FIG. 9, it is preferable that the existing performance event is erased uniformly when it overlaps with the existing performance event.
[0074]
In the real-time recording process, the gate time and velocity of the RTREC event parameter are determined by the operation state of the pad switches 47 and 48 in step S905 of FIG. 9, but are set when the pad switches 47 and 48 are operated. It is also possible to use one or both of the GREC event parameter gate time and velocity for recording performance events in real time recording. In this case, it is not necessary to detect the pressing duration or the detected pressing strength.
[0075]
In the real-time REC process, the RTREC event recording instruction is input by operating the pad switches 47 and 48 (step S903 in FIG. 9). Any method other than the operation, for example, a configuration in which a recording instruction is given by inputting predetermined data including timing information as if actually performing is performed. In this sense, in this embodiment, the operation timing of the pad switches 47 and 48 defines the timing information, and the RTREC event corresponds to the predetermined data.
[0076]
Alternatively, performance data such as MIDI data (including timing information) based on a performance performed by an external device connected through the communication I / F 14 is input, and the performance event in the input performance data is referred to as an RTREC event. At the same time, timing information in the input performance data may be used as a recording performance timing T (R) for real-time recording. In this case, for example, a usage mode such as recording a performance event first input from an external device in a recording target pattern, using this as a starting table, and then adding or deleting performance events can be considered.
[0077]
In the real-time recording process, when a note number is assigned to the pad switches 47 and 48 by default, the assigned note number may be a note number of a GREC event parameter. In addition to this, if the GREC event parameter value is used by default for the RTREC event parameter gate time and velocity, the GREC recorded during grid recording is used by using the pad switch with the default setting. An effect similar to that of making it possible to determine the performance timing of an event (not an RTREC event) with a pad switch can be obtained.
[0078]
It should be noted that the same effect may be obtained by reading a storage medium storing a control program represented by software for achieving the present invention into the apparatus, in which case the data is read from the storage medium. The program code itself realizes the new function of the present invention, and the storage medium storing the program code constitutes the present invention. Further, the program code may be supplied via a transmission medium or the like, and in that case, the program code itself constitutes the present invention. In addition, as a storage medium in these cases, a portable medium such as an optical disk and a floppy (registered trademark) disk can be used in addition to a ROM and a hard disk.
[0079]
