DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone signal generator suitable for playing one of a plurality of automatically played parts by a user himself.

[0002]

2. Description of the Related Art Conventionally, there has been known a tone signal generator for automatically playing a plurality of parts. This tone signal generator generates tone signals for each part based on performance information corresponding to each part, and such performance information is generally supplied from an external sequencer in accordance with the progress of the music. You.

[0003] However, according to the automatic performance, since the user only listens to the musical tones generated by the automatic performance, the user lacks interest. For this reason, there has been a spontaneous demand that the user plays one of the plurality of parts by himself and plays a part in the performance.

[0004]

However, some of the automatic performance parts require quite sophisticated performance techniques when actually performing. This corresponds to, for example, a performance part of an electric guitar. In such an electric guitar, it is general that various effectors are connected, and various parameters are set to a musical sound generated by a string to give an effect. As the music progresses, the effector is turned on / off, and a pedal or the like is operated to change the tone.

[0005] However, since such an operation is performed during a performance, it is a very advanced technique for a beginner. Therefore, there is a problem that it is very difficult for a user who is not an advanced person to perform such a performance part. On the other hand, even advanced users can set effectors for specific parts played in automatic performance by themselves, and even set parameters that change in accordance with the progress of the song, based on their own hearing. That is tough.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object the purpose of making it easy to perform an automatic performance by a simple operation when the user wants to play a specific part of the automatic performance. It is another object of the present invention to provide a tone signal generating device capable of participating in the tone signal generation.

[0017]

An embodiment of the present invention will be described below with reference to the drawings.

(Structure of Embodiment) FIG. 1 is a block diagram showing an electric structure of a tone signal generator 1 according to this embodiment. In this figure, reference numeral 11 denotes a CPU, and a ROM 12
Is controlled based on a control program stored in the CPU 10 via the bus 10. 13
Is a RAM, which stores various registers and flags to be described later and temporarily stores data.

Reference numeral 30 denotes a main panel, which comprises various switches and a display unit set by a player, as will be described later, and is provided on the operation surface of this embodiment.
The setting information from the main panel 30 is transmitted to the CPU 1 via an interface (not shown) and the bus 10.
1 is supplied.

Reference numeral 15 denotes a sequencer externally connected to the present embodiment, which is a MIDI (Musical Instrument Digit).
al Interface) The MIDI performance information is sequentially supplied literally via an interface (I / F) 16. Reference numeral 17 denotes a tone generator circuit,
Under the control of, a tone signal is generated based on the MIDI performance information. More specifically, the tone generator circuit 17 in this embodiment generates and outputs 16 parts of musical tones assigned to each timbre simultaneously (time division).

By the way, the tone generation in this embodiment is as follows.
In addition to the sound source circuit 17, the sound source circuit 17 may be connected to a musical instrument such as an electric guitar or a microphone. A musical tone generated by the musical instrument is converted into an electric signal by a sensing device (for example, a pickup) (not shown), and further converted into a digital signal by an ADC (A / D converter) 18. Similarly, the vocal utterance is converted into an electric signal by the microphone and converted into a digital signal by the ADC 18. The output of the ADC 18 is used as an external input together with a tone signal of the tone generator 17 and a DSP (Digital
Signal Processor) 20.

The DSP 20 constructs an effect imparting circuit under the control of the CPU 11 and imparts various effects to the input signal. Then, an output signal of the DSP 20 is output as a generated musical tone according to the present embodiment by a sound system including an amplifier, a speaker, and the like.

(Configuration of Effect Giving Circuit Constructed by DSP) Next, the configuration of the effect imparting circuit constructed by the DSP 20 will be described. FIG. 2 is a block diagram showing the configuration of the circuit.

As shown in FIG. 1, each tone signal corresponding to the parts 1 to 16 of the tone generator 17 and the ADC
The output signal (external input) of the multiplier 18 is
Predetermined multiplier factor is multiplied by 1 ₁ to 21 _17. Multiplication result of the multiplier 21 ₁ is further multiplier 22 _1L, 22
_The signals are supplied to the _1R and weighted, and are distributed (panned) into stereo L signals and R signals.
Similarly, the multiplication result of the multiplier 21 ₂ to 21 _17, are supplied to the multipliers _{22 2L · 22 2R ~22 17L ·} 22 17R, weighted to stereo L and R signals are made. Then, the multipliers 22 _2L・ 22 _{2R to} 22 _17L・ 22
Multiplication result _17R is supplied to a first mixer 23 _first through fourth mixers 23 _4, respectively.

[0025] The first mixer 23 _1, Part 1 to Part 1
6, ADC 18, each L of the second effector 24, _second and third effector 24 _3, after multiplied by the predetermined multiplication coefficient R output signal, L, is intended to be added separately for each system of R.

[0026] Similarly, the second mixer 23 _2, Part 1
Part 16, ADC 18, the L of the first effector 24 ₁ and the third effector 24 _3, after multiplied by the predetermined multiplication coefficient R output signal, L, is intended to be added separately in each system of the R, third the mixer 23 _3, Part 1 Part 1
6, after multiplying each of the L and R output signals of the ADC 18, the first effector 24 ₁ and the second effector 24 _{1 by} a predetermined multiplication coefficient, and adding them separately for each of the L and R systems. 23 _4, Part 1 Part 16, AD
C18, the first effector 24 _1, in which each L of the second effector 24, _second and third effector 24 _3, after multiplied by the predetermined multiplication coefficient R output signal, L, is added separately to each system of R .

[0027] Here, the first effector 24 ₁ is intended to impart a predetermined effect to the input signal. The effect is
Distortion, reverb, delay, chorus, compressor, etc. are prepared, and one of them is selected. That is, one effect is provided by one effector. The output signal of the first effector 24 _{1 and} the signal that does not pass through this effector are the multipliers 25 for the L signal.
_The multipliers 25 _11R and 25 _10R multiply the R signal by a predetermined multiplication coefficient according to _11L and 25 _10L , respectively. Then, the result of this addition becomes the output of the first effector 24 ₁ . This makes it possible to adjust the ratio between the signal to which the effect is applied and the signal to which the effect is not applied. The second effector 24, _second and third effector 24 ₃ is the same as that of the first effector 24 ₁ configuration. The output of the fourth mixer 23 _4, the DS
The output of P20 is supplied to the sound system 19.

The setting of various multiplication coefficients in the DSP 20 and the selection of the effect of each effector can be made by a sub-panel (not shown) in addition to the setting in the flowchart described later.

According to the effect imparting circuit having such a configuration, it is possible to give various effects to a tone signal in a complicated manner, but it is possible to give no effect at all. For example, the first to third and appropriately setting the multiplication factor of the mixer 23 _{1-23 3,} the feed amount of the effector is located downstream (hereinafter referred to as send level) by adjusting, to the tone signal, first effector 24 _1, second effector 24 _2, each effect by third effector 24 ₃ to which can be imparted to the cascade, also can be applied to parallel. Further, for example, a tone signal, the first effector 24 _1, after applying each effect by the second effector 24 ₂ in parallel, it is also possible to impart subsequently the effect of the third effector 24 _3. On the other hand, by the respective send level to the first to third effector 24 _{1-24 3} to zero, simple mixing of Part 1 Part 16 and the external input are also possible.

(Panel Configuration) Next, the configuration of the main panel 30 will be described. FIG. 3 is a plan view showing this configuration. As shown in the figure, the main panel 30 includes a display unit 31, a cursor key 32, and an increment key 3.
3, a decrement key 34, and a wheel 35. Here, the display unit 31 displays various setting conditions, the cursor 32 specifies the direction of the cursor 36 blinking and displayed on the display unit, and the increment key 33, the decrement key 34, and the wheel 35 , The part designated by the cursor 36 is set to a desired value.

Here, each unit displayed on the display unit 31 will be described. In the display contents of FIG. 3, an area 41 indicates a part number which is set at the present time, and an area 42 indicates a MIDI channel set by the part number which is set in the area 41. Is shown. Next, the area 43 shows the program number changed by the program change, and the area 44
Shows the timbre name assigned to the program number in the area 43.

Next, an area 45 shows the correspondence between the part / external input and the MIDI channel. Here, the area 46 indicates the number of MIDI channels to which an external input via the ADC 18 is assigned. In the area 47, the output of the tone generator circuit 17 or the output of the ADC 18 corresponding to the part and the external input is muted.
The setting state of whether to turn off is indicated. When the state is off, “□” is displayed, and when the state is on, “■” is displayed. Note that this mute on / off designation is performed by moving the cursor 36 and moving the increment key 3
By operating the 3 or decrement key 34, the setting can be made for each part.

In the area 48, the setting state of the AD lock, which will be described later, is displayed as “□” when it is off, and is displayed as “■” when it is on.

After all, in the display of FIG.
Part 16 is MIDI channel 1
It is understood that the MIDI channel 16 is supported, and from this area 41, it is known that the target of the setting is part 3 at present, and from the area 42, the part is set to the MIDI channel 3. From the area 43, it is found that the tone assigned to the program number is “Dist. Guita” (distortion guitar). But,
The tone signal by the part 3 of the tone generator circuit 17 is muted on (not output).
A signal assigned to the DI channel 3 and input via the ADC 18 is controlled by a MIDI channel 3 control change (described later).

(Structure of Performance Information) Here, the sequencer 1
With reference to FIG. 4, a description will be given of the structure of timbre information that defines the timbre of the generated musical tone, out of the performance information supplied from FIG. The timbre information is supplied corresponding to parts 1 to 16, respectively, and FIG. 4 corresponds to, for example, part 3 among them.

In this figure, the first row shows MIDI
Data indicating a program number for tone color selection sent by a control change of performance information is arranged. In the second row, data indicating a tone color name corresponding to the program number is arranged. In the third to fifth stages, data indicating a waveform, an envelope, and a filter are arranged, and each is used for generating a tone signal in the tone generator circuit 17. In the sixth row, data defining the volume of the part is arranged, and the data sets the multiplication coefficient of the multiplier 21 ₃ (see FIG. 2).

In the seventh row, data defining bread is arranged. Pan, for example, relative to the left of the stereo,
It can be defined by the relative ratio of the right, the multiplication factor of the multiplier 22 _3L and 22 _3R this data is set. On the eighth row, data indicating the type of effect of the first effector 24 ₁ is shown. In the ninth row, data defining the send amount to the effector used in the part is arranged, and this data is used for the first mixer 23.
Of multipliers in _one-third one of the mixers of the mixer 23 _3, the multiplier coefficient of the multiplier that corresponds to the part 3 is set.

The effector to be actually assigned is determined at the time of a program change, and the first effector 24 ₁ to 24 ₁ .
Either effector of the third effector 24 ₃ is assigned. Since the input signal is also determined according to the effector used, the send amount sets the determined multiplication coefficient of the mixer.

(Operation of Embodiment) Next, the operation of the above-described embodiment will be described.

(Main Routine) First, when the power of this embodiment is turned on, a main routine shown in FIG. 5 is started. When this routine is started, first, in step Sa1, a predetermined initialization process is executed, and various registers, flags, and the like are initialized. After this process,
Proceeding to step Sa2, a panel process described below is executed, and in the next step Sa3, a MIDI reception process is performed, and the process returns to step Sa2. Thereafter, the processing of steps Sa2 and Sa3 is repeated until the power is turned off.

(Panel Processing) When the processing proceeds to step Sa2 of the main routine, the panel processing shown in FIG. 6 is started. When this routine is started, first, in step Sb1, it is determined whether or not the mute on / off designation state has changed compared to the previous time, that is, whether or not a mute event has occurred. If there is no event, the following steps Sb2 to Sb6
Since it is not necessary to perform the processing of step Sb7, the process skips to step Sb7.
Proceeding to b2, it is determined whether or not the event is an event from mute off to on.

[0042] When an event to ON, the determination result is "Yes", the process proceeds to step Sb3, to squeeze the part or volume of the external input corresponding to a mute of events, the multiplier 21 ₁ to 21 ₁₇ (see FIG. 2) corresponding one of the multiplication coefficients are set to "0". On the other hand, if the mute event is from ON to OFF, the result of determination in step Sb2 is “N
o ", and the process proceeds to Step Sb4.

In step Sb4, the multiplier 2 sets the volume of the part or external input corresponding to the mute having the off event to the state immediately before the mute is turned on.
Corresponding coefficients of the multiplier coefficient 1 ₁ to 21 ₁₇ is set to the volume value read from the register A. Here, the register A is for storing a volume value that indicates the multiplication factor of the multiplier 21 ₁ to 21 _17, described later step Sc12
In, a value is set.

After the processing of step Sb3 or Sb4, the process proceeds to step Sb5, where the display of the mute having the event in the area 47 of the display unit 30 (see FIG. 3) is "■" in the case of the ON event. In the case of an off-event, it is inverted to “□”. In the next step Sb6, the mute flag indicating mute on / off is inverted to "1" for an ON event and to "0" for an OFF event. In addition,
The mute flag is set corresponding to each of the parts 1 to 16 and the external input. That is, the mute flag in step Sb6 means a mute flag corresponding to a part having an event or an external input.

Next, in step Sb7, it is determined whether or not the state of the AD lock switch has changed compared to the previous time, that is, whether or not there has been an AD lock event. If there is an event, the determination result is “Ye
s ", and in the next step Sb8, the AD flag indicating the state of the AD lock is inverted. Step Sb7
If the result of the determination in step Sb8 is "No", that is, if there is no event of the AD lock switch, or if the process of step Sb8 ends, the panel process ends.

As described above, in the panel processing routine, when the setting of mute or AD lock is changed, the register and flag corresponding to the change are set.

(MIDI Reception Processing) When the processing proceeds to step Sa3 of the main routine described above, FIG. 7 and FIG.
Is activated. When this routine is started, first, in step Sc1, it is determined whether or not an initial reset signal has been supplied.

Here, the initial reset signal is the DSP2
Setting of the effect imparting circuit built with 0, part and MID
This is a signal for setting the correspondence with the I channel and the like to an initial state predetermined by the standard. When such an initial reset signal is not received, the processing skips to Step Sc6 because there is no need to perform the processing of subsequent Steps Sc2 to Sc5. On the other hand, when the initial reset signal is received, first, in step Sc2, the parts 1 to 16 of the tone generator 17 are set to a predetermined initial state. Proceeding to the next step Sc3, the volume, panning, and the amount of send to each effector in the parts 1 to 16 of the tone generator 17 are also set to the initial state. That is, the multiplier 21 ₁ each multiplication coefficient to to 21 _16, the multiplier 22 _1L · 22 _1R ~22 each multiplication factor to _16L · 22 _16R, and the first to fourth mixers 23 ₁ to 23 ₄ Part 1 in Each multiplication coefficient corresponding to part 16 is set to an initial state.

Next, in step Sc4, it is determined whether or not the AD lock is ON by referring to the AD flag. When the AD lock is ON, the process skips to step Sc6 because there is no need to perform the process of step Sc5 next. On the other hand, when the AD lock is off, the process proceeds to step Sc5, where the volume, panning,
And the send amount to each effector is set to the initial state. That is, the multiplication coefficient to the multiplier 21 _17, the multiplier 2
The multiplication coefficients for _217L and _2217R and the multiplication coefficients corresponding to the external inputs in the _first to _fourth mixers 231 to 234 are respectively set to the initial state.

In the following steps Sc6 to Sc17, the effect given to the external input is controlled by the received MIDI performance information. First, in step Sc6, it is determined whether or not a program change has occurred in the received MIDI performance information, that is, whether or not the program number has been changed in the tone color information shown in FIG. If the result of this determination is "No", the process proceeds to step Sc8.
On the other hand, if the determination result is "Yes", the part assigned to the changed MIDI channel is program-changed to change to the tone corresponding to the changed program number.

Turning to FIG. 8, in step Sc8,
It is determined whether a control change has occurred in the received MIDI performance information. Control change in this example, the volume, and only the send level of bread, and to the first effector 24 _1, for otherwise, although not shown in FIGS. 7 and 8 may perform the corresponding processing. If the decision result in the step Sc8 is "No", it is not necessary to perform the processing for each data related to the effect imparting in the following steps Sc9 to Sc16, and the process is immediately skipped to the step Sc17, while the decision result is " If “Yes”, the process proceeds to step Sc9, and first, it is determined whether or not the changed data sets the volume.

If the decision result in the step Sc9 is "No", the process skips to a step Sc13. On the other hand, if the decision result in the step Sc9 is "Yes", the process proceeds to a step Sc10. It is determined whether the mute flag corresponding to the part or the external input assigned to is set to “1”, that is, whether the mute is on.

When the mute is off, the sound is generated as usual, and the volume is changed in step Sc11. Specifically, the multiplication coefficients (see FIG. 2) 21 ₁ to 2
Of 1 _17, coefficients corresponding to part or an external input is assigned to a MIDI channel with volume change is reset to the changed volume value.

On the other hand, when the mute is on, the changed volume value is written to the register A in step Sc12. As a result, when the mute is turned off from the next time on, the part or the external input is sounded at the changed volume value by the processing of step Sb4 described above.

Next, in step Sc13, it is determined whether or not the changed data sets panning. If the determination result in step Sc13 is “No”, the process skips to step Sc15. If the determination result is “Yes”, the process proceeds to step Sc14, where the multiplication coefficients (see FIG. 2) 22 _1L and 22 _1R ~ 22 _{17 L}
Of · 22 _17R, coefficients corresponding to part or an external input is assigned to a MIDI channel bread change is set to the changed value.

[0056] Further, in step Sc15, whether there has been a change data is to set the send level to the first effector 24 ₁ is determined. Step Sc15
If the determination result in step is "No", the process proceeds to step Sc1.
While skip to 7, if the determination result is "Yes", the process proceeds to step Sc16, out of the multiplication coefficient in the first mixer 23 ₁ (see FIG. 2), the MIDI channel for which the send level change The multiplication coefficient corresponding to the assigned part or external input is set to the changed value.

[0057] In FIG. 8, although not shown for brevity, the following processing of step Sc16, the also send level to the second effector 24, _second and third effector 24 _3, in step Sc15 and Sc16 First
Send amount of bets similar process to the effector 24 ₁ is performed. That is, if there is a change in the data to set the send level to the second effector 24 ₂ or the third effector 24 _3, the second mixer 23 ₁ or the third mixer 2
3 ₃ out of the multiplier coefficient (see FIG. 2) in the multiplication coefficient corresponding to the part or external input are assigned to MIDI channel for which the send level change is set to the changed value.

If it is determined in step Sc17 that the received MIDI performance information is data indicating an event, sound generation or mute processing is performed in response to the event, and the MIDI reception processing routine ends.

(Specific Operation Example) Next, a specific operation of the above-described embodiment will be described.

In the case where, for example, an electric guitar is connected as the external input In this case, the player operates the main panel 30 to assign, for example, the external input to the MIDI channel 3 and set the part 3 to mute-on (this The setting state is the same as that shown in FIG. 3). According to this setting state, parts other than part 3 are automatically played based on the MIDI performance information supplied by the sequencer 15, but part 3 is played not by the MIDI performance information but by the electric guitar by the player himself. Will be.

At this time, the musical tones generated by the electric guitar by the performer's own
The effects set by the DI performance information are sequentially applied as the performance progresses, so that the player can concentrate on the performance alone without successively making settings for applying the effects. Therefore, the performance practice can be performed efficiently, and the performance can be easily performed.

When a vocal microphone is connected as an external input, for example, the performer (vocalist) operates the main panel 30 in the same manner as when an electric guitar is connected, and assigns the external input to the MIDI channel 3, for example. , Set Part 3 to mute on. The MIDI channel to which an external input is assigned is preferably an empty channel.

Further, the vocalist is set so that a desired effect is provided by adjusting a sub-panel (not shown), and the AD lock is turned on. According to this setting state, the parts other than the part 3 are automatically played based on the MIDI performance information supplied by the sequencer 15, so that the vocalist uses this as so-called karaoke.

By the initial reset signal at the start of the performance, the generated musical tones of parts 1 to 16 and the effect given to this musical tone signal are set to the initial state defined by the standard (steps Sc2 and Sc3). By the lock-on, the setting of the effect applied to the external input, here, the vocal is not initialized (step Sc5).

Usually, a vocalist sets a desired effect in advance according to his / her taste. However, conventionally, a vocalist himself / herself inputs a setting by receiving an initial reset signal specified by a standard. However, there was a problem of returning to the initial state. In this embodiment, by turning on the AD lock, it is possible to prevent this inconvenience from occurring. Note that M corresponding to Part 3
It is also conceivable that the IDI performance information has data appropriate for vocal setting. In this case, an initial reset may be performed. For this reason, the AD lock can be arbitrarily turned on / off as described above.

In the above-described embodiment, the sound volume, the pan, and the send amount to the effector have been described as the data related to the effect application. However, these are merely examples, and the present invention is not limited thereto.

In the above-described embodiment, the on / off designation of the mute is set by the main panel. However, for example, a sensor for detecting that a microphone or a jack from a sensing device is connected is provided. Mute on / off designation may be set according to the detection result.
