Since the priority rule of the assigner AS (4) is high-tone priority and the number of pronunciations is 1, as shown in FIG. 7 (D), the highest sound of the target key press (at the first and second measures, the highest key press state) In the third and fifth measures, one tone (second tone from the low-pitched side in the key depression state) is determined as the tone pitch of the assigner AS (4).
- step S6 a tone having a tone pitch determined by the tone color of the tenor saxophone is generated.
- step S4 when assigner AS (5) is selected in step S3 of FIG. 3, it is determined in step S4 whether or not the target key depression of assigner AS (5) is included in the current key depression state. Since the target key press of AS (5) is all key presses, it is always determined that there is a target key press, and the process proceeds to step S5. In step S5, the tone pitch at the assigner AS (5) is determined based on the priority rule and the number of pronunciations.
- step S6 a tone having a tone pitch determined by the tone of the baritone sax is generated.
- the first two notes of the first bar of the assigner AS (1) (the part surrounded by the dashed line), the first two notes of the second bar of the assigner AS (2) (the part enclosed by the dashed line), the assigner AS
- the three tones in the fifth bar (the part surrounded by the alternate long and short dash line) in (5) are all pitches not included in the tone range of the live musical instrument corresponding to the tone color set in each assigner AS. These pitches are processed with reference to the setting table for out-of-range note processing shown in FIG. For example, in the setting table for out-of-range note processing shown in FIG.
- the trumpet tone is generated as it is even if the pitch is outside the range, so the first measure of the first measure of the assigner AS (1) And the first two tones of the second bar of the assigner AS (2) (portion surrounded by the dot-and-dash line) are pronounced at the pitch shown in the example of the score.
- FIG. 8 is a musical score showing another example of the key pressing state for explaining the allocation control processing according to the embodiment of the present invention
- FIG. 9 is a case where the allocation control processing is performed on the musical score shown in FIG. Is a musical score representing the sounding states of ASSIGNER AS (1) to AS (3).
- assigners AS (1) to AS (3) are indicated as assigner 1 to assigner 3 for convenience.
- FIG. 10 is another example of the assigner setting table according to the embodiment of the present invention.
- the target key press, the priority rule, the number of pronunciations, and the timbre are defined for each assigner AS, similarly to the assigner setting table shown in FIG.
- step S4 of step S4 it is determined in step S4 whether or not the target key depression of assigner AS (1) is included in the current key depression state. Since the target key press of AS (1) is all key presses, it is always determined that there is a target key press, and the process proceeds to step S5. In step S5, the tone pitch of the assigner AS (1) is determined based on the priority rule and the number of pronunciations.
- step S6 a musical tone having a tone pitch determined by the tone of the violin is generated.
- the assigner AS (2) has other key presses excluding the highest note as the target key press, the priority rule is the priority on the last arrival, and the number of pronunciations Is “unlimited”.
- the tone is set to strings.
- step S4 it is determined in step S4 whether or not the target key press of the assigner AS (2) is included in the current key press state. Since the target key of the assigner AS (2) is a key other than the highest note, when only one key (one note) is played (the first measure of the score), that note is regarded as the highest note. Therefore, it is determined that there is no target key depression. That is, the assigner AS (2) is not sounded when only one note is played.
- step S5 the tone pitch at the assigner AS (2) is determined based on the priority rule and the number of pronunciations.
- the priority rule of the assigner AS (2) is the priority for the last arrival, but the number of pronunciations is unlimited, so FIG.
- step S6 all the sounds (all the target key presses) except the highest key press state are determined as the tone pitch of the assigner AS (2).
- step S6 a tone having a tone pitch determined by the string tone is generated. Note that if the number of pronunciations is not unlimited and the priority rule is late arrival priority, according to the key pressing order included in the key pressing state, the sounds corresponding to the number of pronunciations from the slowest key pressing order are determined as the pronunciation pitch.
- the tone color set in the assigner AS (2) is strings
- the number of pronunciations is set to unlimited. This is because strings are originally created by mixing the sounds of multiple stringed instruments, so there is no need to generate single notes.
- the tone color is set to a violin or a contrabass as in the assigner AS (1) or the later-described assigner AS (3), it is generally a musical instrument that hardly generates two or more sounds, so that a plurality of simultaneous sounds are used. If a tone is set to strings even if there is a key press, it can be set so that multiple sounds are generated if there are multiple simultaneous key presses.
- the assigner AS (3) has other key presses excluding the highest note as the target key press, the priority rule is bass priority, and the number of pronunciations is “1”.
- the tone is set to the contrabass.
- step S4 it is determined in step S4 whether or not the target key press of the assigner AS (3) is included in the current key press state. Since the target key of the assigner AS (3) is a key other than the highest note, when only one key (one note) is played (the first measure of the score), that note is regarded as the highest note. Therefore, it is determined that there is no target key depression. That is, the assigner AS (3) is not sounded when only one note is played.
- step S5 the tone pitch at the assigner AS (3) is determined based on the priority rule and the number of pronunciations, but the priority rule of the assigner AS (3) is bass priority and the number of pronunciations is 1, so FIG. As shown in C), one lowest note in the key depression state is determined as the tone pitch of the assigner AS (3). Thereafter, in step S6, a tone having a tone pitch determined by the tone of the contrabass is generated.
- pitches of measures 3 to 4 of assigner AS (3) are all pitches not included in the range of the live musical instrument corresponding to the tone (contrabass) set in assigner AS (3). . These pitches are processed with reference to the setting table for out-of-range note processing shown in FIG.
- FIG. 11 is another example of a setting table for out-of-range note processing according to an embodiment of the present invention. Similar to the setting table shown in FIG. 5, the tone color, the tone range of the tone color, the note processing outside the tone range, the volume, and the like are defined. In another example shown in FIG. 11, the tone color of “violin” is defined as “G2 to A5”, and even if there is a sounding instruction at a pitch outside this range, it is “sounded as it is”. The volume is set to “100”. Also, the tone color of “Strings” is not set in the tone range, and there is no setting when there is a sounding instruction at a pitch outside this tone range.
- strings are timbres that are a combination of a plurality of stringed instruments, and thus do not have a specific range.
- the volume is set to “64”.
- the tone of “Contrabass” is defined as “E0 to F3” in the tone range, and is “ignore (does not pronounce)” when a tone is issued at a pitch outside this tone range.
- the volume is set to “64”.
- the pitch outside the range is ignored (does not sound) in the setting table of the out-of-range note processing shown in FIG.
- the pitch outside the range of measures 2 to 4 in (3) is ignored.
- “A2” in the fifth measure is within the range, so it is pronounced.
- each assigner AS independently determines the target key press, and the key press determined to be the target of each assigner AS is further based on the priority rule (high tone priority, later The key to be played (pitch) is determined according to the number of pronunciations.
- a predetermined order such as “excludes the highest sound” or “from the low sound side to the second sound” is used.
- a rule that selects or excludes several notes continuously along the order for example, in order of increasing or decreasing pitch. You may comprise so that it may select.
- the selection condition in at least one assigner AS is composed of a combination of two selection rules of “excluding the highest sound” and “excluding the lowest sound”. In this combination, when the number of simultaneous key presses is 1 or 2, since the highest sound and the lowest sound are removed, the target key press is “none”.
- the assigner AS does not assign a timbre to the pressed pitch, so that no sound is assigned, and no sound is generated via the assigner AS.
- the number of simultaneous key presses is 3
- the middle key of the three key presses excluding the highest tone and the lowest tone is selected as the target key press and pronounced.
- the number of keys simultaneously pressed is 4 or more
- a plurality of keys corresponding to intermediate pitches among the plurality of keys pressed are selected as the target keys, and one or more finally pronounced according to the priority order. Multiple keys are determined.
- the number of pressed keys is 2 or less, the sound is not generated, and when it is 3 or more, the key corresponding to the intermediate pitch (if there are multiple keys, the sound having the highest priority among them) is assigned to be sounded. Can be assigned.
- the selection condition in at least one assigner AS is a combination of two selection rules of “excluding the highest sound” and “from the high sound side to the second sound”.
- the assigner AS does not assign a timbre to the pressed pitch, so that no sound is assigned, and no sound is generated via the assigner AS.
- the number of key presses is 2 or more, the state where the highest sound is removed from the two sounds from the high sound side, that is, the second sound from the high sound side is the target key press.
- the process of determining the pitch to be pronounced for each assigner AS (1) to AS (n) (that is, the pitches to which the timbre is assigned by the assigner in steps S4 and S5).
- the selection process and the priority key selection rule and the priority rule that are the same for two or more assigners. May be executed by only one assigner. If the assigner has the same setting, the pitch to be generated is the same, so the tone determined based on the executed process 1 is also applied to other assigners with the same setting, and the tone is assigned. What should I do?
- each assigner is provided with a target key selection rule and a priority rule, but may be used in combination with an assigner that does not have these rules.
- the present invention is applied to some of a plurality of assigners to determine the pitch based on the target key selection selection rule, the priority rule, and the number of pronunciations, and the remaining assigners are the target key press. There may be an application in which the pitch is determined based only on the priority rule without the selection rule.
- the embodiment of the present invention is not limited to the form of the electronic musical instrument, and may be implemented by a commercially available computer or the like in which a computer program corresponding to the embodiment is installed.
- a computer program or the like corresponding to each embodiment may be provided to the user while being stored in a recording medium that can be read by a computer such as a CD-ROM.
- a computer program, various data, and the like may be provided to the user via the communication network.
