TECHNICAL FIELD OF THE INVENTION
The present invention relates to a performance information recording device capable of recording a performance event using a function called a “grid recording function”.
[0002]
[Prior art]
Conventionally, there has been known a performance information recording device for recording performance information defined by a performance event and a performance timing of the performance event. For example, in Non-Patent Document 1 described 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 device of Non-patent Document 1 described below, 16 grid recording switches are provided, and for example, two bars of a certain performance part are set as a recording target pattern, and each grid recording switch has two bars. Each is associated with a beat timing (eighth note). The user sets a performance event for recording during grid recording. Here, the performance event includes parameters such as pitch (note number), gate time, velocity, and the like. In the rhythm part, the pitch is a parameter that defines the type of musical instrument.
[0004]
During the operation of the grid recording function, depression of the grid recording switch is received while reproducing the recording target pattern. When any of the grid recording switches 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 recording switch is pressed. Therefore, the performance event is recorded at a position corresponding to the performance timing corresponding to the pressed grid recording switch in the recording target pattern. .

[Problems to be solved by the invention]
However, in the device of Non-Patent Document 1, during the operation of the grid recording function, the performance event can be input only by the grid recording switch. For example, the performance event is input in real time while listening to the recording target pattern to be reproduced. Can not be recorded. Even when real-time recording can be performed using a mode other than the grid recording function mode, it is necessary to perform an input operation after changing to the other mode.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
FIG. 1 is a block diagram showing the overall configuration of a performance information recording device according to one embodiment of the present invention. The present performance information recording device is configured as an electronic musical instrument such as a rhythm machine.
[0014]

Etc. are converted to sound.
[0017]
FIG. 2 is a diagram showing the configuration of the operation panel of the present apparatus. The operation panel of this apparatus includes a display screen 30 such as a liquid crystal display, dial-type parameter operators 41 (41A, 41B, 41C), a pitch input switch 43 (five), a grid recording switch 45 (eight), and each sound. LED 42 (five) corresponding to high input switch 43, LED 44 (eight) corresponding to each grid recording 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.
[0018]
The parameter operator 41, the LEDs 42 and 44, and the various switches 43, 45, 46, 47 and 48 are provided on the operation unit 20. The LEDs 42 and 44 are arranged above the corresponding pitch input switch 43 and grid rec switch 45, respectively. In the following, when the eight grid recording switches 45 or the LEDs 44 corresponding thereto are separately described, the serial numbers are assigned, and the grid recording switches 45 (1), 45 (8), the LEDs 44 (1), 44 Described as (8).
[0019]
In the present apparatus, performance information can be recorded using a function called "grid recording function". In the grid recording, a predetermined length (for example, four measures) of a performance part to be recorded is set as a “recording pattern (performance information)”, and a grid recording event is recorded as a performance event by depressing the grid recording switch 45. Record in a pattern.
[0020]
The display screen 30 displays the parameters of the grid recording event and their values. Hereinafter, the grid recording event is abbreviated as “GREC event”, and the parameter of the grid recording event is abbreviated as “GREC event parameter”. The GREC event is a recording performance event recorded in the recording target pattern when any one of the grid recording switches 45 is pressed next time. The GREC event parameter is stored in, for example, a GREC event buffer in the RAM 11.
[0021]
The GREC event parameters include “note number” indicating a pitch, “gate time” indicating a sounding time length, and “velocity” indicating a sounding volume. In the normal manual setting, “note number”, “gate time”, and “velocity” can be individually set by the parameter operators 41A, 41B, and 41C, respectively, and the display units 31, 32, and 33 in the display screen 30 are displayed. Displays the current setting value. In the example shown in the figure, they are "C3", "80%", and "103", respectively.
[0022]
The user can arbitrarily select one of all the pitches that can be set as the pitch data during the GREC event using the parameter operator 41A, and assign a new note number in the order of the pitch for each operation. You can call and enter. In the present embodiment, the inputtable pitches are 128 (0 to 127). When a rhythm part is created, the pitch (note number) defines the type of percussion instrument, so setting the note number corresponds to selecting the type of percussion instrument.
[0023]
The pitch input switch 43 and the grid recording switch 45 are arranged so as to imitate a black key and a white key of the keyboard, respectively. Is operable. The grid recording switch 45 is also used for inputting a GREC event in the grid recording function.
[0024]
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 the first two bars or the second two bars of the recording target pattern are selected. Each grid recording switch 45 is assigned in advance a “performance timing T” that defines at what time position in the recording target pattern the current GREC event is to be recorded. The eight grid recording switches 45 respectively correspond to the selected two-measure beat timings (quarter notes), and the data indicating the corresponding beat timings corresponds to the performance timing T.
[0025]
Actually, as described later, each GREC event is associated with timing data TD indicating a time interval (counter value from the head) from the position of the first beat of the selected second measure of each recording target pattern. The timing data TD is defined by the performance timing T. The data may not be the timing data TD as long as the data can define the performance timing of the performance event to be recorded. For example, the performance timing may be defined by the duration from the immediately preceding performance event. Good.
[0026]
The LEDs 42 and 44 are turned on in response to the operation 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 with respect to the note number currently set as the GREC event parameter. The LED 44 also performs a blinking operation to indicate the current playback position when the recording target pattern is continuously played back in the grid recording function.
[0027]
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. As will be described in detail later, by pressing the scan switch 46, the desired note number selected from the created "note number list (predetermined pitch group)" can be changed.
[0028]
In the present embodiment, even during the operation of the “grid recording function”, the “real-time recording” can be performed by operating the pad switches 47 and 48. In the 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.
[0029]
With the grid recording switch 45, the GREC event can be recorded only at the performance timing T assigned to the grid recording switch 45, but with the pad switches 47 and 48, the real-time recording event is recorded at the performance timing T corresponding to the operation timing thereof. can do. The 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".
[0030]
The operation state (on / off, operation timing, pressing time, pressing strength) of the pad switches 47 and 48 is detected by the detection circuit 16. An arbitrary note number can be assigned and set to each of the pad switches 47 and 48, and the set note number is set to one of the parameters of the RTREC event recorded by operating the respective pad switches 47 and 48. The note number is one.
[0031]
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. That is, 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 press continuation time, and the velocity is set based on the detected press strength.
[0032]
3 to 6 are diagrams showing an example of the state of the performance data and the operation panel when the grid recording function operates.
[0033]
Each figure (a) is a conceptual diagram of a part of the performance data for the recording target pattern (four measures). This performance data is stored in, for example, the RAM 11. In one recording target pattern, there are 16 beat timings in 4 beats, and in the example of FIG. 3A, a performance event whose note number is “C3”, “D3”, or “G3” corresponds to the first bar. Recorded on the first beat.
[0034]
Each figure (b) shows the lighting state of the LED 44 corresponding to the grid recording switch 45, and in each figure (b), the black circle shows the 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 events recorded in the selected two measures of the recording target pattern, The corresponding LEDs 44 are individually lit. For example, assuming that the note number is “D3” in the current setting of the GREC event parameter, in the example of FIG. 3A, as shown in FIG. 3B, the grid recording switches 45 (1), 45 ( Only the LEDs 44 (1) and 44 (5) corresponding to 5) are turned on. The lighting state of the LED 44 can be changed by not only the operation of the parameter operator 41A but also the operation of the scan switch 46 and the pad switches 47 and 48, as described later.
[0035]
During the operation of the grid recording function, usually, for example, the first two measures of the recording target pattern are selected, and the GREC event parameter is set by the parameter operator 41. By pressing a desired grid recording switch 45 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 recording switch 45 in the recording target pattern. . Each time the user inputs a GREC event, the user changes the GREC event parameter with the parameter operator 41 as necessary, and repeats the pressing operation. By performing the same operation for the latter two measures, one performance pattern of the performance part is completed.
[0036]
Next, the scan processing and the real-time rec processing in parallel with the grid rec function operation will be described with reference to FIGS. 3 to 6 using the flowcharts of FIGS.
[0037]
FIG. 7 is a diagram showing a flowchart of the 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 the real-time recording process of FIG. 9 described later is also started. . In this process, the user sets a recording target pattern and selects the first or second half bars. 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 during this processing by a switching operator (not shown) of the operation unit 20. As described above, the recording target pattern is repeatedly reproduced, and the LED blinks according to the progress thereof, so that the current reproduction position can be known.
[0038]
First, it is determined whether or not an operation of the parameter operator 41, that is, an instruction to change the GREC event parameter has been made (step S701). If no change instruction has been made, the process proceeds to step S704. The GREC event parameter is changed according to the change instruction (step S702). That is, new values are set for the note number, gate time, and velocity 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.
[0039]
Next, various displays are changed according to 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 display unit 31 displays the changed note number, and reads out only the performance event having the changed note number in the recording target pattern. Only the LED 44 (corresponding to the position of the read performance event) corresponding to the timing data TD associated with is turned on (see FIG. 3). Thereafter, the process proceeds to step S704.
[0040]
In step S704, it is determined whether a recording instruction for a GREC event has been detected based on whether any one (or a plurality of) of the eight grid recording switches 45 has been pressed. As a result of the determination, when the recording instruction of the GREC event is not detected, the process proceeds to step S708. When the recording instruction of the GREC event is detected, the recording performance timing T (R) in the recording of the GREC event is determined (step S705). ). Here, the performance timing T assigned to the pressed grid recording switch 45 is determined as the recording performance timing T (R).
[0041]
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 of the same note number has already been recorded at the same position to be written, the previously recorded performance event is erased without writing. Therefore, when the same grid recording switch 45 is repeatedly pressed with the same note number, recording and erasing of the performance event of the note number are alternately repeated. Next, the LED display is updated (step S707).
[0042]
Here, the processing of steps S704 to S707 will be specifically exemplified. For example, when the performance data of the recording target pattern is set as shown in FIG. 4A and the note number of the GREC event parameter is set to “G3”, the grid recording switch 45 (8) is pressed. Then, as shown in FIG. 5A, a performance event of note number "G3" is added to 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 turned on. At this time, since the GREC event parameter is not changed, the display on the display screen 30 does not change.
[0043]
Next, in step S708, it is determined whether or not an ON operation of the scan switch 46 has been detected. If the ON operation has been detected, a scan process of FIG. 8 described later is executed (step S709), and the process proceeds to step S710. On the other hand, if the on operation is not detected, the process proceeds to step S710 without executing the scanning process.
[0044]
In step S710, it is determined whether or not an instruction to stop the grid recording function has been detected. If the instruction to stop the grid recording has not been detected, the process returns to step S701. Is stopped, and the writing to the recording target pattern is terminated (step S711), and this processing is terminated.
[0045]
FIG. 8 is a diagram showing a flowchart of the scan processing executed in step S709 of FIG.
[0046]
First, pitches (note numbers) are extracted from 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 recording target pattern are stored in the order of the pitches, and are created as a list. This note number list is stored in, for example, the RAM 11. Note that the range in which the note numbers listed in the note number list are extracted need not be limited to the recording target pattern (four measures) as in the present embodiment, but may be, for example, the entire range of the selected performance part for one song. Alternatively, conversely, only the selected first or second half bars may be set as the range. Further, it is desirable that the extraction range can be changed each time.
[0047]
Next, the next higher note number 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 according to the newly set note number value (step S804), and the process ends.
[0048]
This processing will be described in detail with reference to FIGS. 3 and 4. For example, now, the performance data of the recording target pattern is set as shown in FIG. 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 step S801, three types of note numbers "C3", "D3", and "G3" are extracted from all the performance events in the recording target pattern. A number list is created.
[0049]
Then, in step S802, "G3" is selected as the next highest note number with respect to the note number "D3" currently set in the GREC event parameter. If there is no next highest 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.
[0050]
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 note number selection is the next highest note number in the order of pitch, but is not limited to this. For example, the next lowest note number may be selected. Alternatively, the user may be allowed to select a desired note number from the note number list. In this case, each time the scan switch 46 is pressed, a candidate note number may be read.
[0051]
In the step S804, the display of the LED 44 and the display screen 30 is changed. 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 turned on corresponding to the position of the performance event (FIG. 4B).
[0052]
After the scan processing, grid recording can be performed using the changed GREC event parameter, and the changed GREC event is a performance event recorded when the grid recording switch 45 is pressed next time.
[0053]
FIG. 9 is a diagram showing a flowchart of the real-time REC processing. This processing is executed at a predetermined interruption interval during the execution of the main processing of 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 grid recording, and is executed, for example, 48 times per quarter note. In this process, it is assumed that a default note number or a desired note number is assigned by the user to each of the pad switches 47 and 48.
[0054]
First, based on the timing of the counter, it is determined whether or not a performance event to be generated at the current performance timing is recorded in the recording target pattern (step S901). The performance event is read and sounded (step S902), and the process proceeds to step S903. 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 as needed due to the grid recording or the real-time recording, the latest content is always the reproduction target.
[0055]
In step S903, it is determined whether an instruction to record an RTREC event has been detected based on whether one of the pad switches 47 and 48 has been operated. The operations of the pad switches 47 and 48 are detected independently of each other, and there may be duplication. As a result of the determination, if the recording instruction of the RTREC event is not detected, the process proceeds to step S907. If the recording instruction of the RTREC event is detected, the recording performance timing T (R) in the recording of the RTREC event is determined (step S904). ). Here, the recording performance timing T (R) of the RTREC event is determined according to 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).
[0056]
Next, a performance event writing process is performed (step S905). That is, an RTREC event is additionally written as a performance event at a position corresponding to the performance timing T (R) for recording in the pattern to be recorded. Here, as described above, the pitch (note number) assigned to the operated pad switches 47 and 48 is set as the RTREC event parameter, but the gate time and velocity are detected respectively. The pressing duration is set based on the detected pressing strength. Therefore, even during the grid recording, the user can perform a performance event of a desired pitch and volume for a note number preset in the pad switches 47 and 48 within a range of the resolution of the interruption interval. Location can be recorded.
[0057]
Here, the time interval of the interrupt processing is small, and in actuality, there is little overlap with existing performance events. However, in a real-time REC, it is often desired to input a performance event at an arbitrary timing, so that an attempt is made to write. Only when a performance event of the same note number has already been recorded at exactly the same position, an RTREC event to be newly recorded is ignored, that is, not written, and otherwise, all are written. If the performance timings of the RTREC event to be newly recorded and the existing performance event are extremely close (for example, a shift of several cycles of interrupt processing), input at the same timing is performed according to the concept of quantization. It may be determined that the event has occurred, and the existing performance event may be uniformly deleted.
[0058]
Next, the display or the like is updated (step S906). Here, not only the display of the LED 44 but also the content and display of the GREC event parameter are updated. That is, as for the GREC event parameter, the note numbers assigned to the operated pad switches 47 and 48 are newly set as note numbers. 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 real-time recording. Note that the configuration may be such 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.
[0059]
Regarding the display of the LED 44, only the performance events having the note numbers assigned to the operated pad switches 47 and 48 are read out in the recording target pattern, and the timing data associated with the read performance events are read out. Only the LED 44 corresponding to TD is turned on. Note that the performance event recorded by the real-time recording may not coincide with the beat timing due to the interruption processing interval. In this case, the LED 44 corresponding to the beat timing closest to the performance event is displayed. Is turned on.
[0060]
The processing of steps S903 to S906 will be specifically exemplified. For example, as an example, 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 a corresponding position near the position of the sixth beat of the recording target pattern. Note that the performance event of “G3” is not strictly added to the position of the sixth beat, but to the position of 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 sixth beat for easy viewing.
[0061]
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 display section 31 displays the changed note number.
[0062]
Returning to FIG. 9, next, in step S907, the value of the counter is increased, the performance of the recording target pattern is advanced, and this processing ends. The counter counts the length of the pattern to be recorded (for four measures), and when the counter reaches the end of the four measures, resets the value and restarts counting from the beginning of the four measures.
[0063]
Thus, when the grid recording and the real-time recording 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 recording switch 45 is pressed in the grid recording, and is determined by the performance progress timing (counter value) when the pad switches 47 and 48 are pressed in the real time recording.
[0064]
According to the present embodiment, during the operation of the grid recording function, each time the scan switch 46 is pressed, the note number of the GREC event parameter is changed to the next highest note number in the note number list. In the same recording target pattern, when the user wants to re-enter the same pitch as that input in the past, the desired note number can be quickly and easily set as a GREC event parameter without operating the parameter operator 41A one by one. You can do it again. Therefore, it is possible to easily input a pitch input in the past, and to efficiently record a performance event by a simple operation.
[0065]
Further, 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 intuitively easy to understand and the note number can be easily set.
[0066]
According to the present embodiment, even during the operation of the grid recording function, the inputs from the pad switches 47 and 48 are accepted and real-time recording is enabled, so that the performance is performed at a performance timing finer than the minimum resolution determined by the grid recording switch 45. Even when it is desired to record an event, it is possible to easily input a performance event 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 the normal grid recording recording operation and the real-time recording operation, and it is possible to create various intended performance patterns by a simple operation.
[0067]
In addition, since a desired note number can be assigned to the pad switches 47 and 48, a desired pitch is recorded according to the operation timing only by operating the pad switches 47 and 48, and the usability is good. .
[0068]
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. .
[0069]
The note number list may be created arbitrarily by the user, for example, by collecting note numbers that are considered to be frequently used, or included in the note number list created by extracting from the recording target pattern. Note number may be added. In this way, it is possible to easily input a frequently used note number, and to more efficiently record performance events.
[0070]
In the scanning process, in step S803 in FIG. 8, only the note number in the GREC event parameter is updated. However, 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 the note number selected from the note number list as a parameter in the recording target pattern may be adopted as the update parameter.
[0071]
The LEDs 42 and 44, the pitch input switch 43, and the grid recording switch 45 are not limited to the illustrated numbers. In particular, the LED 44 and the grid recording switch 45 are divided into four measures according to the length of the recording target pattern. It is desirable to double the number of arrangements correspondingly. The pattern to be recorded is four measures of the performance part to be recorded. However, the pattern is not limited to four measures.
[0072]
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 the case where an existing performance event overlaps with the existing performance event in step S905 in FIG. 9, it is preferable that the existing performance event is uniformly deleted.
[0073]
In the real-time REC processing, in step S905 of FIG. 9, the gate time and velocity of the RTREC event parameter are determined based on the operation states of the pad switches 47 and 48, but are set when the pad switches 47 and 48 are operated. It is also possible to use one or both of the gate time and the velocity of the existing GREC event parameter for recording a performance event in a real-time REC. In this case, it is not necessary to detect the pressing duration or the detected pressing strength.
[0074]
In the real-time REC processing, an instruction to record an RTREC event is input by operating the pad switches 47 and 48 (step S903 in FIG. 9). However, the present invention is not limited to this. Any configuration 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 a performance may be used. In this sense, in the present embodiment, the operation timing of the pad switches 47 and 48 defines the timing information, and the RTREC event corresponds to the predetermined data.
[0075]
Alternatively, performance data (containing timing information) such as MIDI data based on a performance performed by an external device connected via the communication I / F 14 is input, and the performance event in the input performance data is defined as an RTREC event. In addition, the 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, it is conceivable that a performance event input from an external device is first recorded in a recording target pattern, and this is used as a starting point, and thereafter, a performance event is added or deleted.
[0076]
In the real-time REC processing, when a note number is assigned to the pad switches 47 and 48 by default, the assigned note number may be the note number of the GREC event parameter. In addition, if the value of the GREC event parameter is also used by default for the gate time and velocity in the RTREC event parameter, the GREC recorded during grid recording can be performed by using the pad switch with the default setting. An effect similar to that in which the performance timing of an event (not an RTREC event) can be determined by a pad switch can be substantially obtained.
[0077]
Note that a similar effect may be obtained by reading a storage medium storing a control program represented by software for achieving the present invention into the present apparatus. In this case, the storage medium read out from the storage medium may be used. The program code itself realizes the novel 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 the ROM and the hard disk.
[0078]
【The invention's effect】
As described above, according to the present invention, both normal recording operation and real-time recording operation can be used simultaneously, and intended performance information can be created by a simple operation.
