　（２）音色設定制御部８の機能的な構成
　図２は図１の音色設定制御部８の機能的な構成を示すブロック図である。図２に示すように、音色設定制御部８は、機能選択部８１、音色切替部８２、音色取得部８３、音色設定部８４および処理部８５を含む。図１のＣＰＵ１１がＲＯＭ１０または記憶装置１３に記憶された音色設定プログラムを実行することにより図２の音色設定制御部８の各部の機能が実現される。 (2) Functional Configuration of Tone Setting Control Unit 8 FIG. 2 is a block diagram showing a functional configuration of the timbre setting control unit 8 of FIG. As shown in FIG. 2, the timbre setting control unit 8 includes a function selection unit 81, a timbre switching unit 82, a timbre acquisition unit 83, a timbre setting unit 84, and a processing unit 85. The CPU 11 in FIG. 1 executes the timbre setting program stored in the ROM 10 or the storage device 13, thereby realizing the functions of the respective units of the timbre setting control unit 8 in FIG.
　機能選択部８１は、設定操作子４の操作に基づいて、電子音響装置１において実行する所定の機能（以下、特定機能と呼ぶ。）を選択する。特定機能は、例えば練習機能および自動伴奏機能を含む。ここで、練習機能は、練習用の楽曲の進行に合わせて操作すべき演奏操作子２をガイドすることにより、楽曲の演奏を使用者に習得させるための機能である。自動伴奏機能は、伴奏スタイルのカテゴリに対応して設けられた伴奏データと与えられたコードとに基づいて伴奏音を自動的に出力する機能である。 The function selection unit 81 selects a predetermined function (hereinafter referred to as a specific function) to be executed in the electronic acoustic device 1 based on the operation of the setting operator 4. Specific functions include, for example, a practice function and an automatic accompaniment function. Here, the practice function is a function for allowing the user to learn the music performance by guiding the performance operator 2 to be operated in accordance with the progress of the music for practice. The automatic accompaniment function is a function for automatically outputting an accompaniment sound based on accompaniment data provided corresponding to the accompaniment style category and a given chord.
　音色切替部８２は、特定機能が実行されないとき（特定機能の不実行時）には、設定操作子４が操作されるごとに予め定められた第１の代表音色と予め定められた第２の代表音色との間で音源回路１６に設定されるべき音色を切り替える。本実施の形態では、特定機能が実行されないときとは、練習機能および自動伴奏機能を用いない通常の演奏時をいう。 When the specific function is not executed (when the specific function is not executed), the timbre switching unit 82 is set to a predetermined first representative timbre and a predetermined second each time the setting operator 4 is operated. The tone color to be set in the tone generator circuit 16 is switched between the representative tone colors. In the present embodiment, the case where the specific function is not executed means a normal performance time when the practice function and the automatic accompaniment function are not used.
　ここで、中東、インドまたは中国等の民族音楽を演奏する場合、使用者には、民族楽器の音色が好まれることがある。したがって、本実施の形態では、第１の代表音色として音色カテゴリ「オリエンタル」の第１番目の音色（例えば「ウード音色」）が予め定められる。一方で、演奏の経験が少ない使用者には、発音開始の認識が容易であること、他のパートの再生中でも聴き分けが容易であること、およびなじみがあること等の理由から、演奏音の認識が容易な「ピアノ音色」が好まれることがある。したがって、本実施の形態では、第２の代表音色として「ピアノ音色」が予め定められる。 Here, when playing folk music from the Middle East, India, China, etc., the user may prefer the tone of folk instruments. Therefore, in the present embodiment, the first timbre (for example, “oude timbre”) of the timbre category “Oriental” is determined in advance as the first representative timbre. On the other hand, for users who have little experience in performance, it is easy to recognize the start of pronunciation, easy to hear while playing other parts, and familiarity. “Piano tone” that is easy to recognize may be preferred. Therefore, in this embodiment, “piano timbre” is predetermined as the second representative timbre.
　音色取得部８３は、特定機能の実行時に音源回路１６に設定されるべき第３の代表音色と当該特定機能の種類との対応関係を予め記憶している。音色取得部８３は、特定機能の実行時に、記憶された対応関係に基づいて当該特定機能に対応する第３の代表音色を取得する。練習機能の実行時においては、第３の代表音色は、例えば「ピアノ音色」である。自動伴奏機能の実行時においては、第３の代表音色は、伴奏スタイルのカテゴリに対応する音色カテゴリの第１番目の音色である。 The tone color acquisition unit 83 stores in advance a correspondence relationship between the third representative tone color to be set in the sound source circuit 16 and the type of the specific function when the specific function is executed. The timbre acquisition unit 83 acquires a third representative timbre corresponding to the specific function based on the stored correspondence relationship when the specific function is executed. When the practice function is executed, the third representative tone color is, for example, a “piano tone color”. When the automatic accompaniment function is executed, the third representative tone color is the first tone color of the tone color category corresponding to the accompaniment style category.
　図３は伴奏スタイルのカテゴリと第３の代表音色との対応関係の一例を示す図である。図３の例では、伴奏スタイルのカテゴリが「アラビック」である場合、音色カテゴリ「オリエンタル」の第１番目の音色である「ウード音色」が第３の代表音色に該当する。伴奏スタイルのカテゴリが「バラード」である場合、音色カテゴリ「ピアノ」の第１番目の音色である「グランドピアノ音色」が第３の代表音色に該当する。伴奏スタイルのカテゴリと第３の代表音色との対応関係は、図３の例に限定されず、所定の法則により他の対応関係が決定されてもよい。 FIG. 3 is a diagram showing an example of the correspondence between the accompaniment style category and the third representative tone color. In the example of FIG. 3, when the accompaniment style category is “Arabic”, the “ood tone color” that is the first tone color of the tone color category “Oriental” corresponds to the third representative tone color. When the accompaniment style category is “ballad”, the “grand piano timbre” that is the first timbre of the timbre category “piano” corresponds to the third representative timbre. The correspondence relationship between the accompaniment style category and the third representative tone color is not limited to the example of FIG. 3, and another correspondence relationship may be determined according to a predetermined rule.
　図２の音色設定部８４は、使用者による設定操作子４の操作に基づいて、任意の音色を設定する。練習用の楽曲データには、音色を指定するための音色指定情報が含まれる。音色設定部８４は、処理部８５により練習用の楽曲データが取得された場合には、当該楽曲データの音色指定情報により指定された音色を設定する。 The timbre setting unit 84 in FIG. 2 sets an arbitrary timbre based on the operation of the setting operator 4 by the user. The music data for practice includes timbre designation information for designating the timbre. When the musical piece data for practice is acquired by the processing unit 85, the timbre setting unit 84 sets the timbre designated by the timbre designation information of the musical piece data.
　また、音色設定部８４は、使用者による設定操作子４の操作に基づいて、音色切替部８２により切り替えられた第１もしくは第２の代表音色、または音色取得部８３により取得された第３の代表音色を設定する。したがって、特定機能の実行時に設定操作子４が操作されると、第３の代表音色が設定され、特定機能の不実行時に設定操作子４が操作されると、操作ごとに設定される音色が第１の代表音色と第２の代表音色との間で切り替わる。 Further, the timbre setting unit 84 is the first or second representative timbre switched by the timbre switching unit 82 or the third timbre acquired by the timbre acquisition unit 83 based on the operation of the setting operator 4 by the user. Set the representative tone. Accordingly, when the setting operator 4 is operated when the specific function is executed, the third representative tone color is set. When the setting operator 4 is operated when the specific function is not executed, the tone color set for each operation is set. Switching between the first representative tone color and the second representative tone color.
　処理部８５は、特定機能を実行するための種々の処理を行う。具体的には、機能選択部８１により練習機能が選択された場合、処理部８５は、設定操作子４の操作に基づいて練習用の楽曲データを記憶装置１３から取得し、取得した楽曲の進行に合わせて操作すべき演奏操作子２をガイドする。機能選択部８１により自動伴奏機能が選択された場合、処理部８５は、設定操作子４の操作に基づいて伴奏データを記憶装置１３から取得するとともに演奏操作子２からコードを取得する。 The processing unit 85 performs various processes for executing the specific function. Specifically, when the practice function is selected by the function selection unit 81, the processing unit 85 acquires music data for practice from the storage device 13 based on the operation of the setting operator 4, and the progress of the acquired music The performance operator 2 to be operated in accordance with is guided. When the automatic accompaniment function is selected by the function selection unit 81, the processing unit 85 acquires accompaniment data from the storage device 13 and acquires a chord from the performance operator 2 based on the operation of the setting operator 4.
　演奏操作子２が鍵盤である場合、処理部８５は、音色の設定が変更されることに伴い鍵盤に割り当てられるスケールを変更してもよい。例えば、処理部８５は、平均律により定められるスケールを特定の民族音楽に適する他のスケールに変更してもよい。また、処理部８５は、音色の設定が変更されることに伴いピッチベンド時のピッチの変化幅を調整してもよい。 When the performance operator 2 is a keyboard, the processing unit 85 may change the scale assigned to the keyboard as the timbre setting is changed. For example, the processing unit 85 may change the scale determined by the equal temperament to another scale suitable for specific folk music. Further, the processing unit 85 may adjust the pitch change width at the time of pitch bend as the timbre setting is changed.
　音源回路１６は、例えば演奏操作子２により与えられる発音指示信号に応答して、音色設定部８４により設定された音色を有する音響信号を生成する。また、音源回路１６は、自動伴奏機能の実行時に、処理部８５により取得された伴奏データおよびコードに基づいて伴奏用の音響信号を生成する。 The sound source circuit 16 generates an acoustic signal having a timbre set by the timbre setting unit 84 in response to, for example, a sound generation instruction signal given by the performance operator 2. The sound source circuit 16 generates an accompaniment sound signal based on the accompaniment data and code acquired by the processing unit 85 when the automatic accompaniment function is executed.
　（３）音色設定処理
　図４および図５は音色設定制御部８により行われる音色設定処理を示すフローチャートである。図６は音色設定処理により設定される音色の例を示す図である。図４および図５の音色設定処理は、図１のＣＰＵ１１がＲＯＭ１０または記憶装置１３に記憶された音色設定プログラムを実行することにより行われる。 (3) Tone Setting Process FIGS. 4 and 5 are flowcharts showing the tone color setting process performed by the tone color setting control unit 8. FIG. 6 is a diagram showing an example of a timbre set by the timbre setting process. The timbre setting process of FIGS. 4 and 5 is performed by the CPU 11 of FIG. 1 executing a timbre setting program stored in the ROM 10 or the storage device 13.
　まず、音色設定部８４は、使用者による設定操作子４の操作に基づいて音色が指示されたか否かを判定する（ステップＳ１）。音色が指示されない場合、音色設定部８４はステップＳ３に進む。この場合、現時点の音色の設定が維持される。なお、初期時点において、使用者が音色を指示しない場合、既定の音色の設定が維持される。一方、ステップＳ１で音色が指示された場合、音色設定部８４は、指示された音色を設定する（ステップＳ２）。 First, the timbre setting unit 84 determines whether or not a timbre has been instructed based on the operation of the setting operator 4 by the user (step S1). If no tone color is instructed, the tone color setting unit 84 proceeds to step S3. In this case, the current tone color setting is maintained. If the user does not specify a timbre at the initial time, the default timbre setting is maintained. On the other hand, when a timbre is instructed in step S1, the timbre setting unit 84 sets the instructed timbre (step S2).
　次に、処理部８５は、機能選択部８１により練習機能が選択されたか否かを判定する（ステップＳ３）。練習機能が選択されない場合、処理部８５はステップＳ６に進む。練習機能が選択された場合、処理部８５は、自動伴奏機能を不実行にするとともに（ステップＳ４）、練習機能を実行する（ステップＳ５）。 Next, the processing unit 85 determines whether or not the practice function has been selected by the function selection unit 81 (step S3). If the practice function is not selected, the processing unit 85 proceeds to step S6. When the practice function is selected, the processing unit 85 disables the automatic accompaniment function (step S4) and executes the practice function (step S5).
　次に、処理部８５は、使用者による設定操作子４の操作に基づいて練習用の楽曲が選択されたか否かを判定する（ステップＳ６）。楽曲が選択されない場合、処理部８５はステップＳ９に進む。楽曲が選択された場合、処理部８５は、記憶装置１３から選択された楽曲を示す楽曲データを取得する（ステップＳ７）。音色設定部８４は、処理部８５により取得された楽曲データの音色指定情報に基づいて音色を設定する（ステップＳ８）。 Next, the processing unit 85 determines whether or not a music for practice has been selected based on the operation of the setting operator 4 by the user (step S6). If no music is selected, the processing unit 85 proceeds to step S9. When the music is selected, the processing unit 85 acquires music data indicating the selected music from the storage device 13 (step S7). The timbre setting unit 84 sets a timbre based on the timbre designation information of the music data acquired by the processing unit 85 (step S8).
　次に、処理部８５は、使用者による設定操作子４の操作に基づいて自動伴奏データが選択されたか否かを判定する（ステップＳ９）。自動伴奏データが選択されない場合、処理部８５はステップＳ１３に進む。自動伴奏データが選択された場合、処理部８５は、記憶装置１３から選択された自動伴奏データを取得する（ステップＳ１０）。また、処理部８５は、練習機能を不実行にするとともに（ステップＳ１１）、自動伴奏機能を実行する（ステップＳ１２）。 Next, the processing unit 85 determines whether or not automatic accompaniment data has been selected based on the operation of the setting operator 4 by the user (step S9). If automatic accompaniment data is not selected, the processing unit 85 proceeds to step S13. When the automatic accompaniment data is selected, the processing unit 85 acquires the selected automatic accompaniment data from the storage device 13 (step S10). The processing unit 85 disables the practice function (step S11) and executes the automatic accompaniment function (step S12).
