DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of electronic musical instruments, and inputs information indicating a designated value for designating a tone characteristic such as a tone color or an effect from the outside.
The present invention relates to a tone characteristic setting device that appropriately sets a tone characteristic according to an input designated value and controls a generated tone according to the setting.

[0002]

2. Description of the Related Art Conventionally, pitch data or timbre of a musical tone,
An electronic musical instrument provided with musical tone generating means for controlling the generation of musical tones based on musical tone control data for designating effects and the like, wherein pitch data or musical tone control data is supplied from outside the electronic musical instrument, The tone pitch, tone color, effect, and the like of the musical tone generated in the above are controlled, but pitch data or tone control data supplied from the outside is used as it is.

In general, there are various types of such electronic musical instruments, from low-grade models to high-grade models. The high-grade models have a wider sound range (pitch range) than low-grade models, and have functions such as timbre and effects. Usually there are many. In addition, the number of functions of the range, timbre, and effect may differ depending on the specifications between similar models. For this reason, pitch data and tone control data are configured for each model in a form suitable for that model.If pitch data and tone control data for one model are used as they are, Often there was no control over the instrument. That is, depending on the model of an electronic musical instrument (especially a low-grade model), the number of timbres that can generate musical tones and the number of effects that can be provided by the musical instrument are determined by the number of timbres or effects that can be specified by specifying information such as timbres or effects that can be input to the musical instrument. The number may be smaller than the number, and in such a case, there is a problem how to control the musical tone characteristics in the electronic musical instrument in accordance with the input information such as the tone color or the effect.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and inputs information indicating a designated value for designating a tone characteristic such as a tone color or an effect from an external device. When setting the tone characteristics according to the value, the number of tones that can generate a tone or the number of effects that can be given is less than the number of tones or effects that can be specified by input information such as tone or effect. In addition to providing a tone characteristic setting device capable of appropriately setting tone characteristics in accordance with input information such as tone color or effect,
It is another object of the present invention to provide a tone characteristic setting device which prevents setting of inappropriate tone characteristics.

[0005]

Means for Solving the Problems The invention according to this application is:
A tone characteristic setting device for setting characteristics of a tone generated by a tone generating means, wherein, among a plurality of designated values for designating a tone characteristic, a plurality of designated values belonging to a first group are designated. , One musical tone characteristic is associated with each other, and for the specified values belonging to the predetermined second group, each specified value is associated with each musical sound characteristic, and the predetermined third group is assigned. There is no correspondence between the designated value belonging to the musical tone characteristics and the musical tone characteristics. According to this correspondence, the musical instrument has setting means for setting a musical tone characteristic corresponding to the inputted designated value, and is set by the setting means. And controlling the tone generated by the tone generating means in accordance with the tone characteristics, and not performing the control when the association is not set by the setting means. That.

[0006] As described above, the correspondence by the setting means has a specific form according to whether the input designated value belongs to the first group, the second group, or the third group. The tone characteristics can be set in an appropriate form according to the attribute. That is, for the designated values belonging to the first group, the number of tone characteristics that can be generated or controlled by the tone generating means is smaller than the number of tone characteristics that can be designated by the designated value of the attribute that can be input. However, it is possible to appropriately set one tone characteristic (this is a duplicate of a plurality of designated values) in accordance with the input designated value and perform tone control without delay based on this. it can. Further, as for the designated values belonging to the predetermined second group, since each designated value is associated with each tone characteristic, tone control can be performed without any problem based on this. Since the designated values belonging to the third group are not associated with the tone characteristics, tone control based on this is not performed. Therefore, the tone characteristics can be appropriately set according to the attribute of the input designated value.

That is, as for the designated values belonging to the first group, one musical tone characteristic is associated with a plurality of designated values in an overlapping manner, so that the designated musical tone characteristics can be generated or controlled by the musical tone generating means. When the specified value is input, the tone control according to the tone characteristic can be performed by setting the tone characteristic. On the other hand, the value of the input specified value itself is generated or controlled by the tone generating means. Even if the tone characteristics that can be specified are not originally specified, the setting means causes the specified value to overlap with another specified value and be associated with one predetermined tone characteristic, so that By setting the selected tone characteristics, tone control according to the tone characteristics can be performed. Therefore, the original tone characteristics or the original tone characteristics can be controlled in accordance with the specified information such as the input tone color or effect. And so its alternative tone characteristics and which can be set appropriately tone characteristics. On the other hand, as for the designated values belonging to the second group, since each designated value is associated with each tone characteristic, the tone characteristics can be set without any problem based on this. Since the designated values belonging to the third group are not associated with the musical tone characteristics, the musical tone characteristics are not set according to this.
Therefore, tone control based on this is not performed. Therefore, generation of a musical tone due to inappropriate musical tone characteristics is prevented.

In the embodiment described below, an example of setting tone characteristics such as tone and effect is shown. The tone data conversion circuit 32 (FIG. 4) and the effect data conversion circuit 36 are provided.
In the circuit part including (FIG. 5), a designated value for designating a tone characteristic and a tone characteristic are associated with each other, and information for designating a timbre or an effect by a digital data value is input from outside, and this input information is input. , The associated tone characteristics are set.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of an electronic musical instrument according to the present invention, in which the present invention is applied to an electronic musical instrument having an automatic performance device.

The data reading device 10 is for reading performance data relating to a musical piece from external recording means, such as a magnetic tape, a punch card, or a bar code print, which is arbitrary. The data is stored in a data memory 12 composed of a RAM (random access memory) in a format as shown in FIG.

In FIG. 2, performance data is composed of notes N1, N
The note data corresponding to each note includes pitch data PTD indicating a pitch and note length data NLD indicating a note length. Between tone pitch data PTD and note length data NLD corresponding to the first note N1, tone color data TCD for initial tone color setting and effect data EFD for initial effect setting are inserted. For the second and subsequent notes, the tone color data TCD or the effect data E is placed at the note position corresponding to the timing at which the tone or effect is to be changed.
FDs are inserted respectively. Note that the pitch data PTD,
Tone data TCD, effect data EFD and note length data N
To the LD, a pitch mark Mp, a tone color mark MT, an effect mark ME, and a note length mark MN are respectively added to enable identification of each data.

When a performance start switch (not shown) is turned on, the data reading circuit 14 reads from the data memory 12 pitch data PTD and timbre data TC corresponding to the note N1.
D, the effect data EFD and the note length data NLD are sequentially read. The read pitch data PTD is stored in the pitch register 16.
Detects the pitch mark Mp.
The read tone data TCD is loaded into the register 18 in response to the tone register 18 detecting the tone mark MT, and the read effect data EFD is read by the effect register 20 detecting the effect mark ME. Is taken into the register 20 in response to

The read note length data NLD is used by the data read circuit 14 to determine the read timing of data corresponding to the next note N2. That is, based on the note length data NLD corresponding to the first note N1, the data reading circuit 14 measures the time corresponding to the note length indicated by the data NLD by counting the tempo clock signal and the like, and corresponds to the note length. When the time is reached, the data memory 12
, The pitch data PTD and note length data NLD corresponding to the second note N2 are read. Then, the same data reading operation is performed on data corresponding to the third and subsequent notes. In addition, the contents of the registers 16, 18, and 20 are updated by the corresponding read data in accordance with such data read.

The first pitch data PTD from the pitch register 16 is converted through the pitch data conversion circuit 22 into the converted data PTD.
Key press display circuit 24 and tone signal forming circuit 2 as TD '
6. The key press display circuit 24 includes a plurality of display elements 30 provided corresponding to a plurality of keys of the keyboard 28.
The display element corresponding to the first note is turned on according to the conversion data PTD '. Therefore, the player of the keyboard 28 can easily know the key to be pressed first. Note that such a key press display operation is similarly performed every time new pitch data PTD is transmitted from the pitch register 16.

When the pitch register 16 sends out the first tone data PTD, the tone register 18 sends out the first tone data TCD and the effect register 20 sends out the first effect EFD. The timbre data TCD from the timbre register 18 is supplied to the timbre control data memory 34 via the timbre data conversion circuit 32 as conversion data TCD '. This memory 34 is a ROM storing tone control data for each tone such as piano, flute, violin, etc.
(Read only memory), etc., and the timbre control data TC corresponding to the timbre indicated by the conversion data TCD '.
Is supplied to the tone signal forming circuit 26. The effect data EFD from the effect register 20 is transmitted to the effect data conversion circuit 3.
6 is supplied to the tone signal forming circuit 26 as conversion data EFD '.

The tone signal forming circuit 26 generates a tone based on the converted data PTD 'from the pitch data converting circuit 22, the tone color control data TC from the memory 34, and the converted data EFD' from the effect data converting circuit 36. The tone pitch of the tone signal is determined according to the converted data PTD ', the tone is determined according to the tone color control data TC, and the effect is determined according to the converted data EFD'.

When the pitch data corresponding to the first note N1 is supplied to the tone signal forming circuit 26 as the converted data PTD ', the circuit 26 initializes the tone data by the tone color control data TC and the converted data EFD'. A tone signal corresponding to the note N1 is formed so as to indicate the tone and the effect obtained. Then, the formed tone signal is supplied to the speaker 40 via the output amplifier 38, and is converted into sound. Accordingly, a tone corresponding to the note N1 is produced from the speaker 40.

Such a tone generation operation is similarly performed on read data corresponding to each of the second and subsequent notes. When data corresponding to newly read tone color data is generated as tone color control data TC, the tone color characteristics of the tone signal forming circuit 26 are changed and controlled accordingly. When data corresponding to the newly read effect data is generated as the conversion data EFD ', the effect characteristics of the tone signal forming circuit 26 are changed and controlled accordingly.

The player can perform a manual performance on the keyboard 28 in accordance with the automatic performance sound generated as described above and, if necessary, by referring to the key depression display. Each key of the keyboard 28 drives a corresponding key switch of the key switch circuit 42, and the key switch circuit 4
2 is a tone signal forming circuit 2 for depressing key press data indicating a depressed key.
6

The tone signal forming circuit 26 forms a tone signal corresponding to the key depression indicated by the key depression data from the key switch circuit 42 and supplies it to the speaker 40 via the output amplifier 38. Therefore, a manual performance sound is also output from the speaker 40.

FIG. 3 shows a specific example of the pitch data conversion circuit 22 in the case where the octave of the pedal keyboard (PK) sound is changed. In this case, the range of the PK sound is in the range of C2 to C4 for the high-end model, and C2 to C4 for the low-end model.
It is assumed that the pitch data PTD is in the range of C3 and is configured according to a high-end model.

The pitch data PTD includes note code data NC indicating a note name, octave code data OC indicating an octave, and keyboard code data KBC indicating a keyboard name. Octave code data OC is O1 ~
An octave to which C2 belongs, an octave to which C # 2 to C3 belong, and a octave to which C3 belongs
The following Table 1 shows the octaves to which # 3 to C4 belong.
The code contents are defined as shown in FIG.

[0024]

[Table 1]

The circuit shown in FIG. 3 cannot directly handle pitch data specifying the octave to which C # 3 to C4 belongs in a low-grade model. Therefore, this circuit converts this pitch data to data specifying the octave to which C # 2 to C3 belongs. It is configured to convert. That is, when detecting the arrival of PK pitch data based on the keyboard code data KBC, the PK detection circuit 50 supplies an output signal “1” to the AND gate 52.
At this time, the octave code data O of the PK pitch data
Assuming that C designates the octave to which C # 3 to C4 belongs and that the signals O1 and O2 are "1", the AND gate 52 supplies the output signal "1" to one input terminal of the AND gate 54. I do. Since the "1" signal source is connected to the other input terminal of the AND gate 54 in the case of a low-grade model,
The ND gate 54 supplies the output signal "1" to the inverter 56. Inverter 56 generates an output signal "0" in response to the output signal "1" from AND gate 54, and turns off AND gate 58. Therefore, the signal O1 is AND
The signal is converted from “1” to “0” by the gate 58.

As a result, the PK pitch data specifying the octave to which C # 3 to C4 belongs is converted to data PTD 'specifying the octave to which C # 2 to C3 belongs. Therefore,
As far as the octave to which C # 3 and C4 belong, the PK sound (bass sound) is generated one octave lower in the low-grade model than in the high-grade model.

When a conversion circuit as shown in FIG. 3 is provided in a high-end model, a "0" signal source may be connected to the AND gate 54 instead of a "1" signal source. By doing so, the AND gate 58 is always in a conductive state,
Octave code data OC is output without conversion.

FIG. 4 shows a specific example of the timbre data conversion circuit 32 in the case of changing the timbre of the upper keyboard (UK) sound. In this case, the tone of the UK sound is piano, flute, violin, vocal (tenor),
Eight tones of guitar, clarinet, viola and vocal (soprano) can be specified. For low-grade models, only four tones of piano, flute, violin and vocal (tenor) can be specified. It is assumed that Tone data TCD is U
It is composed of tone color group designation data GC indicating a tone color group corresponding to K, LK (lower keyboard), PK, etc., and tone color designation data CC including three bits Q1 to Q3.
Are defined for each tone color as shown in Table 2 below.

[0029]

[Table 2]

The circuit shown in FIG. 4 is configured to change the timbre data of the B group to the timbre data of the A group since the lower grade model cannot handle the timbres of the B group in Table 2. That is, when the UK timbre detection circuit 60 detects the arrival of UK timbre data based on the timbre group designation data GC, it supplies an output signal “1” to one input terminal of the NAND gate 62. Since the "1" signal source is connected to the other input terminal of the NAND gate 62 in the case of a low-grade model, the NAND gate 62 generates the output signal "0" and
The ND gate 64 is turned off. At this time, assuming that the UK timbre data specifies one of the timbres belonging to the group B in Table 2 and the signal Q3 is "1", the signal Q3 is changed from "1" to "0" by the AND gate 64. "
Is converted to

As a result, the timbre data specifying the timbre of the B group in Table 2 is converted to data TCD 'specifying the timbre of the A group in Table 2. That is, the tone of the guitar is changed to the piano, the clarinet is changed to the flute, the viola is changed to the violin, and the vocal (soprano) is changed to the vocal (tenor). In other words, when the tone color of the B group that cannot be generated by the low-grade electronic musical instrument is an attenuated tone color (guitar), another tone color (piano) that can be generated by the low-grade electronic musical instrument is designated. When the tone of the B group is a continuous tone (clarinet, viola), another tone of a continuous tone (flute, violin, etc.) that can be generated by the low-grade electronic musical instrument is converted to the data TCD ′. ) Is converted to data TCD ′. When a high-end model is provided with a conversion circuit as shown in FIG. 4, a "0" signal source may be connected to the NAND gate 62 instead of the "1" signal source.

FIG. 5 shows a specific example of the effect data conversion circuit 36. The circuit in this example is intended for use in low-grade models that have only the ON / OFF control function of the sustain effect and vibrato effect as the effect control function. It is configured to derive only a signal.

The effect data EFD is configured for a high-end model, and includes a sustain control signal SU, a tremolo control signal TR, a duet control signal DU... A delay vibrato control signal DVB, and a vibrato control signal VB. Of these effect control signals, the tremolo control signal TR, the duet control signal DU... Delay vibrato control signal DVB are AND gates AG1, AG2.
Gn is supplied to one input terminal. Here, in the case of a low-grade model, a "0" signal source is connected to the other input terminal of each of the AND gates AG1 to AGn, so that each AND gate is non-conductive. Therefore, the tremolo control signal TR, the duet control signal DU... The delay vibrato control signal DVB
Are blocked by the AND gates AG1 to AGn, and only the sustain control signal SU and the vibrato control signal VB are sent out as the conversion data EFD '. When a high-end model is provided with a conversion circuit as shown in FIG. 5, a "1" signal source may be connected to AND gates AG1 to AGn instead of a "0" signal source.

In the above embodiment, the performance data is read from the external recording means and stored in the RAM.
A convertible ROM storing performance data may be provided, and the performance data may be read from the ROM to perform an automatic performance. This eliminates the need for a data reading device and replaces the RAM with the ROM. In the above embodiment, the data conversion circuit may be provided between the data reading device 10 and the tone signal forming circuit 26. For example, the data conversion circuit is provided between the data reading device 10 and the data memory 12, and The type (pitch, timbre, effect, etc.) may be detected and data conversion may be performed in a stage preceding the data memory 12.
