Abstract

PROBLEM TO BE SOLVED: To efficiently alter respective timbres and vary sound volume by timbres as the timbres are altered through easy operation. SOLUTION: A ROM is stored with an arrangement table containing 128 timbres as a standard timbre group (original) and six extension timbre groups consisting of timbres and sound volume (correction information (%) to be altered corresponding to the timbres, and 25 timbres as the standard timbre group and 4 extension timbre groups are shown. For example, when a timbre name (voice name) having a timbre number (voice NO). '2' in the standard timbre group is 'Electric Grand Piano', this timbre is not changed (NOP) and the sound volume is not changed (correction quantity: 100%) either on condition that a player specifies '1 (Piano)' with an arrangement switch. When the player specifies '2 (Choir)' with the arrangement switch, on the other hand, the timbre '(Electric Grand Piano)' is changed to 'Voice Oohs' (human voice) having a timbre number '53' in the standard timbre group and the sound volume is corrected to 104% as standard sound volume.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument which can generate musical tones with a plurality of tones and which can edit each tone and generate musical tones with the edited tones.

[0002]

2. Description of the Related Art Conventionally, it has been possible to edit each tone color.
The so-called "preset" function is known.

The preset function is, for example, MIDI.
(Musical Instrument Digital Interface) A function that allows a user to arbitrarily change the tone color, volume, etc. assigned to each MIDI channel in accordance with a musical piece in an electronic musical instrument that automatically plays according to data. By using such a preset function, it is possible to rearrange an orchestra song like a piano song, for example.

[0004]

However, in the above-mentioned conventional electronic musical instrument, the preset function merely changes the tone color and volume assigned to each MIDI channel. The preset data could not be used. That is, as described above, even if the orchestra song is rearranged like a piano song by the preset function and the preset data is stored, the original playing song is replaced with the rock song, and this rock song is similarly played on the piano. When rearranging in a musical style, the preset data could not be used at all in most cases. Therefore, the performer has to set again each tone color of the original performance data one by one, and the performer is not bothered.

Further, in the case of making such a setting, conventionally, since the setting is made based on the original performance data as described above, that is, based on a certain reference (standard) (for example, a tone color). Since it is not configured to set, even if you have created similar preset data in the past, the original performance data that is the basis of the preset data and the original performance data that should be changed this time Otherwise, the past preset data could not be reused and the editing efficiency was poor.

Further, since the volume balance of each tone color is set to be optimum depending on the tune, it is necessary to reset the tone color to be optimum according to the change of tone color. Therefore, the tone color is changed. In this case, it is necessary to change not only the tone color but also the volume information. At this time, since the volume when selecting a tone is often set to some value in advance, the volume set in the previous preset, for example, the relative relationship with other tones in the previous preset, It is necessary to check the volume based on the sound and replace it with a new timbre, that is, based on the relationship between the timbre of the previous preset and the timbre of the replaced timbre.If there are many timbres, It is virtually impossible to change the volume for each tone color.

The present invention has been made in view of the above problems, and provides an electronic musical instrument capable of efficiently changing each tone color and the accompanying change of the volume of each tone color by a simple operation. With the goal.

[0008]

In order to achieve the above object, the present invention provides a standard tone color group storing means for storing a plurality of standard tone colors as a set, and a corresponding tone color of the standard tone color group. Extended tone color group storage means for storing a plurality of extended tone color groups that are set tone color groups, extended tone color group selection means for selecting a desired tone color group from the stored plurality of extended tone color groups, and extended tone color group selection When a desired extended timbre set is selected by the means, the musical tone generating means is provided for generating a musical tone with the timbre of the extended timbre set in place of the tone color of the standard timbre set.

Further, preferably, there is provided volume correction information storage means for storing correction information for correcting the volume of each tone color of each extended tone color set in correspondence with the tone color, and the tone generation means has the standard tone sound generation means. The tone color of the tone color group is changed to the tone color of the selected extended tone color group, and the volume of the tone color is corrected by the corresponding correction information to generate a musical tone.

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

FIG. 1 is a block diagram showing a schematic configuration of an electronic musical instrument according to an embodiment of the present invention.

In FIG. 1, the electronic musical instrument of this embodiment has a keyboard 1 for inputting pitch information, a panel switch 2 provided with a switch group for inputting various parameter information, and the like. CPU3 that controls the entire device,
A ROM 4 for storing a control program executed by the CPU 3, table data, etc., and a RAM 5 for temporarily storing various parameter information, calculation results, various input information, etc.
And an external storage device interface (I / F) 6 for connecting an external storage device for storing automatic performance data and the like,
A tone synthesis circuit 7 that synthesizes a tone signal according to the pitch information and various parameters input from the keyboard 1 and a sound system 8 that converts the tone signal from the tone synthesis circuit 7 into sound, such as a speaker. It is composed of and. The respective constituent elements 1 to 7 are connected to each other via a bus 9.

FIG. 2 is a diagram showing an example of the contents of the arrangement table stored in the ROM 4. In FIG. 2, there are 25 tone colors as a standard tone color set (Original), and the tone colors are changed corresponding to each tone color. Tones and volume (correction information (%))
4 sets of extended timbre sets are shown. Actually, the standard timbre set is composed of 128 timbres, and in each extended timbre, the timbres to be changed are associated with all of these 128 timbres, and the extended timbre set is also You can now select 6 sets instead of 4. That is, for convenience of illustration, FIG. 2 shows a suitable selection from the actual arrangement table.

In the figure, the tone color number (Vo
Voice No.) is “2”, Voice Name is “Ele
"ctric Grand Piano" means that when the performer wants to arrange the original musical piece in a piano-like manner, that is, when "1 (Piano)" is designated by an arrange switch (not shown) arranged on the panel switch 2, This tone is not changed (NOP), and the volume is not changed (correction amount is 1
00%). On the other hand, when the performer wants to arrange the original music piece in a chorus style, that is, when the operator selects "2 (Choir)" with the arrangement switch, the tone color "Ele
“Ctric Grand Piano” is a “Voice Oohs” with a standard tone color number “53”.
And the volume is corrected to 104% of the standard volume.

The control processing executed by the electronic musical instrument configured as described above will be described below with reference to FIGS. 3 and 4.

FIGS. 3 and 4 are flow charts showing the procedure of the control process executed by the electronic musical instrument of this embodiment, particularly the CPU 3.

In FIG. 3, first, initial settings such as resetting various ports of the CPU 3 and clearing the RAM 5 are performed (step S1).

Next, the panel switch 2 is scanned (step S2) to determine whether the state of the panel switch has changed, that is, whether there has been a panel switch event (step S3). As a result of this determination, when there is a panel switch event, a process corresponding to the panel switch event, specifically, when the panel switch is the arrangement switch, it is designated from the six extended tone color groups. Arrangement selection processing such as selecting a selected tone color set, and if the panel switch is a start switch for starting automatic performance, automatic performance-related processing such as processing for starting automatic performance is performed (step S4). On the other hand, as a result of the determination in step S3, when there is no panel switch event, step S4 is skipped and the process proceeds to step S5.

In step S5, each key of the keyboard 1 is scanned, and in step S6, it is determined whether or not there is a key event. As a result of this determination, when there is a key event, key event processing according to the key event,
Specifically, when a key event is generated, or when the generated key event is an event caused by key depression, the key event is written in the sounding waiting buffer, while when it is an event caused by key release, Give instructions to stop the sound being played that corresponds to the event. On the other hand, as a result of the determination in step S6, when there is no key event, step S7 is skipped and the process proceeds to step S8.

In step S8, it is determined whether or not the automatic performance is being reproduced. When the automatic performance is being reproduced, automatic performance processing, specifically, generation of an automatic performance event from automatic performance data and generation thereof When the generated automatic performance event is an event that requires sounding, processing such as writing to the sounding waiting buffer is performed (step S9). On the other hand, if it is determined in step S8 that the automatic performance reproduction is not in progress, step S9 is skipped and the process proceeds to step S10.

In step S10, the tone generation waiting buffer is scanned, and in step S11 of FIG. 4, it is determined whether or not there is a tone generation waiting event in the tone generation waiting buffer.
In this determination, if there is a pronunciation waiting event, the pronunciation waiting event is taken out (step S12), the tone color information in the taken pronunciation waiting event, and the currently selected arrangement number (as shown in FIG. 2 above). A number is given to each extended timbre set, for example, "1" is given to "Piano") and the contents of the arrangement table, that is, the contents of the extended timbre set corresponding to the arrangement number. , Timbre number is determined (step S1
3).

In the same manner, from the extracted volume information during the tone generation waiting event, the currently selected arrangement number and the contents of the arrangement table, that is, the contents of the extended timbre set corresponding to the arrangement number, The volume information is corrected (step S14). Specifically, the original volume information is multiplied by the correction amount selected from the arrangement table, and the result is divided by "100". This is because the correction amount is set in%.

Further, the tone generator synthesizing circuit 7 is caused to sound the tone pitch during the extracted tone generation waiting event in accordance with the tone color number determined in step S13 and the volume information corrected in step S14. An instruction is given (step S15).

On the other hand, if it is determined in step S11 that there is no sound generation waiting event in the sound generation waiting buffer, steps S12 to S15 are skipped and the process proceeds to step S16.

In step S16, after performing other processing than the above-described processing, the process proceeds to step S2 of FIG. 3 and the above-mentioned processing is repeated.

As described above, in the present embodiment,
Since each tone color of the standard tone color set is used as a reference and editing is performed for each tone color set, the performer can easily change each tone color. Further, since the extended timbre set and each timbre of each extended timbre set are selected in advance so as to be optimal for the standard timbre set, even a beginner can easily change the style (timbre set) of a song. .

Further, when the extended timbre set is selected and the timbre shifts from the standard timbre set to the extended timbre set, its volume is also corrected according to the change of the timbre. Therefore, it is changed when the timbre is changed. It is possible to eliminate the discomfort caused by the fact that the previous volume is not changed.

Further, since the root of the tone color arrangement is changed, it is not necessary to reset each preset, and the efficiency of tone color editing can be improved.

Although the arrangement table is stored in the ROM 4 in the present embodiment, the arrangement table is not limited to this and may be stored in the RAM 5. By doing so, it is possible to select only desired tone color data from the tone color data of the preset extended tone color group and change it to an arbitrary tone color.

[0030]

As described above, according to the present invention,
A plurality of standard tones are stored as one set, and a plurality of extended tone sets, which are tone sets set corresponding to each tone of the standard tone set, are stored. From the stored plurality of extended tone sets, When a desired timbre set is selected, a musical tone is generated with the timbre of the extended timbre set instead of the timbre of the standard timbre set, so that each timbre can be efficiently changed by a simple operation. Produce an effect.

Preferably, correction information for correcting the volume of each tone color of each extended tone color set is stored in association with the tone color, and a desired tone color set is selected from the stored plurality of extended tone color sets. Then, the timbre of the standard timbre set is changed to the timbre of the selected extended timbre set, and a tone is generated by correcting the volume of the timbre with the corresponding correction information. In this case, it is possible to eliminate the discomfort caused by the fact that the volume before change is not changed.
