Field of the Invention The present invention relates to an electronic musical instrument, and more particularly, to an electronic musical instrument for controlling a touch response corresponding to an operation speed and an operation intensity of a performance operator.

[0002]

2. Description of the Related Art An electronic musical instrument is provided with a touch response function in order to reflect a key pressing speed (touch speed) and a key pressing force as a volume and a tone on a musical tone to be generated. As a method of the touch response in the electronic musical instrument, for example, a plurality of types are prepared in advance, and a player selects the type appropriately with a switch or the like, or a conversion table for converting a key operation into musical sound information such as volume. As described in Japanese Patent Application Laid-Open No. 60-158491, the maximum or minimum data of the key pressing speed can be freely specified by the player. Some automatically correspond to the maximum or minimum data, respectively.

[0003]

However, in such a conventional touch response method, if a player selects a plurality of types of touch responses prepared in advance, the method is suitable for everybody. A type cannot be prepared, and individual characteristics, individual differences, tastes, and the like of individuals cannot be sufficiently reflected. In the case where the conversion table is freely created by the player, it is possible to create a touch response according to the personality and taste of the individual by creating the conversion table. Not only requires considerable skill, but also is a tedious and difficult task, but also the essence that the data input operation for creating the conversion table for the player does not intuitively correspond to the strength of the key operation of the performance Problem. Further, in Japanese Patent Application Laid-Open No. Sho 60-158491, the maximum or minimum data of the key pressing speed is merely matched with the maximum or minimum data of the specifiable range of the touch response. There is a problem that it is not possible to obtain an appropriate touch response corresponding to the personality, taste, etc. of each individual.

Accordingly, an object of the present invention is to enable a player to easily obtain a touch response suitable for a player's actual performance without performing a special operation.

Program ROM (data conversion means) 5
Stores a program for controlling the electronic musical instrument 1 and a plurality of types of conversion tables for converting velocity data from the touch detection unit 3 into tone control data such as volume and tone. In the present embodiment, the conversion table is, for example, a 4 as shown in the lower part of FIG.
One conversion table is stored in the program ROM 5. The conversion table 1 is a conversion table for making the output musical tone control data relatively large with respect to the input velocity data. The conversion table 2 is a conversion table for the output musical tone data with respect to the input velocity data. The conversion table 3 is a conversion table for making control data relatively small. The conversion table 3 is a conversion table for making small input velocity data large and the large input velocity data is small. The conversion table 4 is for converting small input velocity data to small and large. This is a conversion table for increasing input velocity data.

The CPU 3 uses the working RAM 6 as a work memory in accordance with the program stored in the program ROM 5 to perform various types of arithmetic processing, and outputs control signals for controlling each part of the electronic musical instrument 1 based on the arithmetic results. A conversion table stored in the program ROM 5 is selected from the velocity data input from the touch detection unit 3, and the velocity data input from the touch detection unit 3 is converted into musical tone control data based on the selected conversion table. And outputs it to the sound source 9. The working RAM 6 stores velocity data data, pitches, and the like input from the touch detection unit 3 by a performance operation.

The switch unit 7 includes various switches for setting various conditions when the electronic musical instrument 1 is used, in particular, a velocity switch for selecting a conversion table selection mode, a stop switch for terminating the conversion table selection mode, and the like. The CPU 3 scans the switch setting state of the switch unit 7 and performs processing corresponding to the switch selection state.

The display unit 8 is, for example, a liquid crystal display device, and displays and outputs various information provided from the electronic musical instrument 1 to a player.

The tone generator 9 generates a digital tone signal in accordance with tone control data and pitch data input from the CPU 4 and outputs the digital tone signal to the D / A converter 10. The D / A converter 10 converts a digital tone signal input from the sound source 9 into an analog tone signal and outputs the analog tone signal to the sound system 11. The sound system 11 is configured by an amplifier, a speaker, and the like, and loudspeaks and outputs a musical tone input from the D / A converter 10.

Next, the operation will be described.

The electronic musical instrument 1 performs the same performance operation as that of the actual performance in the conversion table selection mode, thereby selecting a conversion table optimal for the player's key operation from the key operation in the performance operation. Then, in the actual performance, the velocity data of the key operation is converted into the tone control data based on the selected conversion table.

Then, as shown in FIG.
A conversion table selection process and a sound generation process are performed.

That is, when the power is turned on, the CPU 4 first performs an initialization process and initializes various registers and the like (step S1). Next, the switch unit 7 is scanned to check whether the velocity switch is on (step S2). When the velocity switch is on, it is determined that the conversion table is in the selection mode, and the keyboard 2, that is, the touch detection is performed. The unit 3 is scanned to check whether a key is pressed (step S3).

When the player performs a performance in the same manner as the actual performance, and detects a key press in step S3, the velocity data by the key press input from the touch detection unit 3 is stored in the working RAM 6 (step S4). It is checked whether the stop key is turned on by the switch unit 7 (step S5). When the stop key is not turned on, the keys are sequentially depressed, and a series of velocity data input from the touch detection unit 3 is stored in the working RAM as shown in FIG.
6 is stored.

Thereafter, when the stop key is pressed, it is determined that the performance operation for selecting the conversion table has been completed, and the maximum value (MAX) and the minimum value (MIN) of the velocity data by this performance operation are determined. Detection (step S
6), the preset maximum value shown in FIG.
AX) is checked whether it is larger than the detected MAX (step S7).

When the setting MAX is larger than the detection MAX, a preset minimum value shown in FIG.
(IN) is larger than the detected MIN (step S8). In step S8, when the set MIN is larger than the detected MIN, the detected MAX
Since AX is smaller than MIN and the detected MIN is smaller than the set MIN, it corresponds to the pattern 1 in the upper part of FIG. 2, and “1” is set as the selected conversion table No. N (step S29). Select 1 and return to step S2.

When the set MIN is smaller than the detected MIN in step S8, the detected MAX is smaller than the set MAX and the detected MIN is smaller than the set MIN.
This corresponds to the pattern 4 in the upper part of FIG.
o. Set “4” as N (step S10),
The conversion table 4 is selected, and the process returns to step S2.

In step S7, the set MAX is detected MAX.
In the following cases, it is checked whether the set MIN is larger than the detected MIN (step S11). When the set MIN is larger than the detected MIN, the maximum value of the detected velocity data and the maximum value are out of the range of the set MAX and the set MIN. Or corresponds to the pattern 3 in the upper part of FIG. Therefore, the selection conversion table No. N
Is set (step S12), the conversion table 3 is selected, and the process returns to step S2.

When the set MIN is equal to or smaller than the detected MIN in step S11, the detected MAX exceeds the set MAX, but the detected MIN is larger than the set MIN. I do. Therefore, "2" is set as the selection conversion table No. N (step S13), the conversion table 2 is selected, and the process returns to step S2.

In this manner, in the conversion table selection mode, a performance similar to the actual performance is performed, and a conversion table optimal for the key operation is selected. Thereafter, the velocity switch is turned off, and when the velocity switch is detected to be off in step S2, the conversion table selection mode is released, and
Next, when a key is pressed, a sound generation process corresponding to the key is performed.

That is, it is checked whether or not the key is depressed in step S14, and when an ON key operation is performed, the pitch data and velocity data corresponding to the ON operation are stored in the working RAM 6 (step S15). Next, the selection conversion table No. N is checked, and the selection conversion table No.
Using the No. N conversion table, the velocity data is converted and generated into tone control data (step S16). The pitch data and the musical tone control data are output to the sound source 9 to instruct sound generation (step S17). Sound source 9 uses this C
A tone is generated based on the pitch data and tone control data from the PU 4, and the tone is generated via the D / A converter 10 and the sound system 11.

When an off key operation is performed in step S14, the sound source 9 is instructed to silence a tone having a pitch corresponding to the off key operation (step S18).
Mutes the musical tone at the designated pitch.

As described above, a conversion table for converting velocity data into musical tone control data can be selected simply by operating the keys on the keyboard in the same manner as in the actual performance. In the actual performance, the selected conversion table is used. The tone control data can be generated to generate a tone. As a result, it is possible to obtain a touch response suitable for the player's actual performance utilizing the individuality and taste of the individual without performing a special operation by the player.

In the above embodiment, four conversion tables are set. However, the number of conversion tables is not limited to four, and can be set as appropriate.

In the above-described embodiment, the key operation is performed in the same manner as in the actual performance to select the conversion table corresponding to the key operation. However, the present invention is not limited to this.
For example, an arbitrary conversion table may be directly selected from conversion tables prepared in advance by operating a switch of the switch unit 7.
