Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting device for an electronic musical instrument , by which each player can easily set the environment of the electronic musical instrument preferred by each individual.

[0002]

2. Description of the Related Art Various musical tone control parameters are used in electronic musical instruments. These parameters are set to predetermined values according to the timbre. Then, when the performer selects a tone color, the set value corresponding to the tone color is sent to the tone generator as a tone control parameter, and the tone generator operates by using those tone control parameters, and as a result, the tone is selected with the tone color selected by the performer. Is generated. The set value of the tone control parameter can be changed by the player's editing. Also,
There is also an electronic musical instrument in which a set of edited musical tone control parameters is stored and can be read out by a predetermined operation.

[0003]

By the way, some of the tone control parameters are influenced by the preference of the performer. For example, with respect to the pitch bend change range and the external controller (including aftertouch) and the like, there are many cases in which the player has different preference values even if the timbre is the same. Some people find it easy to play because the pitch bend range is ± 2 degrees,
Some people find it easier to play at ± 4 degrees.

In the past, such parameter setting had to be reset for each tone color each time the player changed, which was very troublesome. It is also conceivable to set these parameters in common for all tones (for example, set the parameter for the pitch bend change width in common for all tones), but again each time the performer changes. You have to reset the settings. Further, if the setting is made common to all the tones, it becomes impossible to deal with a case where a special control assignment is desired because a pitch bend or the like is effectively used depending on the tones.

Further, in recent years, the MIDI standard has become widespread, and it is often the case that a tone color (that is, a series of tone control parameters for specifying the tone color) is acquired from an external medium and read into an electronic musical instrument of its own. There is a problem that the above-mentioned parameters having a strong individuality must be redone.

In view of the above-mentioned problems in the conventional example, an object of the present invention is to provide a parameter setting device for an electronic musical instrument which can easily set a performance environment according to a player's preference.

The value of i also corresponds to the page of the personal data edit screen. For example, the display screen 54 of FIG. 4 is the eighth page because it is the screen related to the bend wheel that is the eighth personal data, and is PF if “YES” is selected on the display screen 54.
If (8) = 1 and “NO” is selected, PF (8) = 0.

Next, the operation of the electronic musical instrument of this embodiment will be described with reference to the flow charts of FIGS.

Referring to the main routine of FIG. 5, when the operation of this electronic musical instrument is started, first, in step S1, each register and the like are initialized. In the initial state, the mode is the normal mode and the personal data on flag PDON = 0. Next, key processing is performed in step S2. The key processing detects on / off of the keys on the keyboard,
Tones are generated and erased according to the detection result.

Next, in step S3, a mode switch process and a personal data selection (PDSEL) switch process are performed. Mode switch process, mode switch 2
When the pressing of 1 is detected, if there is pressing, the mode is sequentially switched to the normal mode → the tone color editing mode → the personal data editing mode → ... (other modes) ... → the normal mode. The PDSEL switch process is a process of detecting the depression of the PDSEL switch 22 and switching the personal data ON flag PDON when the PDSEL switch 22 is depressed.

Next, in step S4, the current mode is determined. If the tone color edit mode is selected, the process proceeds to step S5. If the personal data edit mode is selected, step S6 is performed.
In other modes (including the normal mode), the process proceeds to step S7.

In step S5, a tone color parameter editing process is performed in response to the user's operation. The operation in this edit process has been described with reference to FIG. The tone parameter that has been edited is R
Written in AM13. In step S6, the personal data editing process is performed. The operation in this edit process has been described with reference to FIG.
The personal data that has been edited is stored in RAM
Written on 14. In step S7, other processing (processing according to the mode at that time) is performed. Other processes include, for example, a tone color selection mode process, and a process of detecting an operation of the numeric keypad 29 and selecting a tone color is performed. When a new tone color is selected by the tone color selection operation, the state of the personal data on flag PDON does not change before and after the selection. In the normal mode, nothing is done in step S7. Steps S5, S
After S6 and S7, the process proceeds to step S8.

In step S8, operator processing is performed. The operator processing detects an operation of an operator such as a bend wheel or a pedal, and controls a sound source according to the operation if necessary. After step S8, the process returns to step S2 and the subsequent processes are repeated.

FIG. 6 shows a PDSEL switch processing routine executed in step S3 of FIG. PDSEL
The switch processing routine is called when it is detected that the PDSEL switch 22 is pressed. PDSEL
No call is made if the switch 22 is not depressed. First, in step S11, the personal data ON flag PDON is inverted to "1" for "0" and "0" for "1". Next, in step S12, it is determined whether or not the personal data ON flag PDON is "1". When it is "1", the LED 23 is turned on in step S13, and when it is "0", the LED 23 is turned off in step S14. afterwards,
To return.

FIG. 7 shows a key-on event routine executed in step S2 of FIG. The key-on event routine is called when a key press on the keyboard 1 (key-on event) is detected. Not called when there is no key-on event.

First, in step S21, the key code of the key key-on is stored in the register KCD, and the velocity at key-on is stored in the register VEL. Next, step S2
In step 2, the data of each operator such as the pitch bend wheel and pedal is fetched, and in step S23, a sound generation channel is assigned. The channel number of the assigned tone generation channel is stored in the register AN.

Next, in step S24, the tone color parameter data currently selected is read from the RAM 13 and sent to the tone generation channel of the sound source 16 having the channel number AN. The tone color parameters sent in step S24 are not related to personal data. Of the tone color parameters in the RAN 13, those that may be replaced with personal data are not transmitted in step S24.

Next, in step S25, it is determined whether or not the personal data ON flag PDON is "1". If it is not "1", it means that the personal data is not replaced. Therefore, of the tone color parameters currently selected in step S26, those relating to the personal data are read from the RAM 13 and the channel number AN of the tone generator 16 is read. To the sound generation channel of the RAM, and the control data that has already been captured by the operator RAM if necessary.
The data stored in 13 is used for arithmetic processing and then sent to the sounding channel. This arithmetic processing is, for example,
It means that the output of the pitch bend wheel 10 is calculated according to the change width of the pitch bend stored in the RAM 13. Then, in step S29, a note-on signal is sent to the sounding channel of the channel number AN of the sound source 16,
To return.

If the personal data ON flag PDON is "1" in step S25, it means that the personal data is replaced.
Personal data valid flag PF (i) (where i
= 1 to 12) is "1". If all the personal data valid flags PF (i) are "0", it means that all 12 types of personal data are invalid and there is no personal data to be replaced, so the process proceeds to step S26.

If it is determined in step S27 that the personal data valid flag PF (i) is "1", the personal data in the RAM 14 is used as the sound source for the parameter in which PF (i) = 1 in step S28. It sends to the sounding channel of 16 channel number AN, and the control data by the operator already fetched is R if necessary.
After the arithmetic processing using the data stored in the AM 14, it is sent to the tone generation channel.

For the parameter PF (i) = 0, the data of the RAM 13 is sent to the tone generation channel of the sound source 16 having the channel number AN, and the control data by the operator already fetched. RAM1 as required
The data stored in 3 is used for arithmetic processing and then sent to the sounding channel. Then, in step S29, the note-on signal is sent to the sounding channel of the channel number AN of the sound source 16, and the process returns.

FIG. 8 shows the operator processing routine of step S8 of FIG. In the manipulator processing routine, step S
31 performs aftertouch processing, step S32 performs bend wheel processing, step S33 performs modulation wheel processing, step S34 performs breath sensor processing, step S35 performs pedal processing, and step S36 performs joystick processing. In step S37, processing regarding other operators is performed, and then the process returns.

Regarding the processing of the operator of each step, the substantial processing is executed only when each processing timing is reached, and the processing is immediately returned at other timings. In this embodiment, when the manipulator processing routine is entered once, only one manipulator process is executed. That is, when the operator processing routine is first entered, the substantial operator processing is performed only in the after-touch processing in step S31, and the other steps immediately return. Next, when entering the manipulator processing routine, substantial manipulator processing is performed only in the bend wheel processing in step S32, and immediately returns in other steps. The same applies hereinafter.

The processing of these steps S31 to S37 is as follows.
In each case, each operator data is acquired, and if an operation is performed, the sound source is controlled according to the operation.
As an example, the bend wheel process of step S32 will be described in detail.

FIG. 9 shows a bend wheel processing routine. In the bend wheel processing routine, first, step S
At 41, it is determined whether or not it is the bend wheel processing timing. If it is not the bend wheel processing timing, the process directly returns. If it is the bend wheel processing timing, the bend wheel data is fetched in step S42. Next, in step S43, it is determined whether the bend wheel data has changed, that is, whether the bend wheel has been operated. If the bend wheel has not been operated, return as it is. If the bend wheel is operated, it is necessary to pitch bend the musical sound in accordance with the operation, so the process proceeds to step S44.

In step S44, it is determined whether the personal data ON flag PDON is "1". If it is not "1", it means that the personal data is not replaced. Therefore, of the tone color parameters currently selected in step S45, those relating to the bend wheel are read from the RAM 13 and based on the tone color parameters. Bend wheel data is processed and sent to the tone generation channel of the channel number AN of the sound source 16. Then return.

If the personal data ON flag PDON is "1" in step S44, it means that the personal data is replaced. Therefore, step S4 is performed.
In 6, whether or not the personal data regarding the bend wheel is valid, that is, the personal data valid flag PF (8)
Is determined to be "1". If the personal data valid flag PF (8) is not "1", it means that the personal data relating to the bend wheel is invalid, and the process proceeds to step S45. When the personal data valid flag PF (8) is "1" in step S46, personal data regarding the bend wheel is read from the RAM 14 in step S47, the bend wheel data is processed based on the personal data, and the channel of the sound source 16 is processed. It is sent to the sounding channel of number AN. Then return.

The processing of the other operators in FIG. 8 is similar to that in FIG.

According to the above-described embodiment, the performer can individually enable each of the 12 types of personal data according to his or her own preference, and can also disable them if not necessary. Then, by pressing the personal data selection switch 22, it is possible to replace a part of the currently selected timbre parameters with the personal data that has been set effectively. Therefore, even when playing using a tone color parameter supplied from the outside by the card 5 or the like, it is possible to replace a parameter having a strong personality with personal data, and play in a preferable environment for the performer.

In the above embodiment, the above-mentioned 12 types of parameters are taken as the personal data by taking the strong individuality parameters as the personal data, but the present invention is not limited to this and other parameters may be used. Further, although the personal data is stored in the RAM 14 only for one person, the personal data for a plurality of persons may be set and stored so that which personal data is used can be designated by a predetermined selection operation.

Although the instruction to replace the personal data is given by the selection switch 22, the selection may be made by a signal from the outside instead of the switch provided in the instrument body. Also, without a switch,
It may be set whether or not to replace the personal data for each timbre. In this case, if the personal data is set to be invalid, the original tone color parameter will be used.

Furthermore, it may be possible to display whether or not personal data is currently used. The method of setting the personal data is not limited to the method of the above embodiment, and any method may be used.

[0059]

As described above, according to the present invention, musical tone control parameters are replaced by instructions to generate musical tones, so replacement parameters according to the performer's preference are stored in advance. By substituting the parameters, it is possible to easily set the performance environment according to the player's preference. Even when the tone control parameters supplied from the outside are used, the tone control parameters can be replaced with replacement parameters according to the player's preference without reediting the tone control parameters.
