It should be noted, rhythm guitar and if it detects a performance, such as chord is engraved in the piano, the configuration of the chord without changing, in a specific rhythm to the newly set Starring response rate style, a new performance data to carve a chord It is desirable to form. Also, it is desirable to replace percussion instruments such as drums and percussion with rhythm patterns that are specific to the set performance style, instead of simply changing the instrument's tone to the instrument tone used in the set performance style. .

  Next, the tone conversion reproduction process will be described with reference to the flowchart shown in FIG. This musical tone reproduction process is a process performed by the CPU 2 executing the musical tone reproduction program 6 a stored in the hard disk 6. Also, in this process, either the tone color setting mode or the style setting mode is selected, and after setting how to change in the setting screen shown in FIG. 2, an audio signal is input to the A / D converter 7. This routine is started each time it is converted into a digital signal by the A / D converter 7 and input to the CPU 2.

  First, a musical sound is input (S1), the musical sound is decomposed for each part, and the pitch of the musical sound for each part is detected (S2). The detected pitch is stored in an area for storing the pitch for each part in the RAM 13, and then the level for each part of the input musical sound is detected (S3). Similarly, the detected level is stored in an area for storing the level of each part of the RAM 13, and the tone of the input musical tone is detected (S4). Similarly, the detected timbre is stored in an area for storing the timbre for each part of the RAM 13.

  Next, it is determined whether or not the mode selected by the user is the tone color setting mode (S5). If the selected mode is the timbre setting mode (S5: Yes), a note is then given depending on whether the pitch, level, timbre, etc. of the part selected to change the musical tone mode has changed. It is determined whether or not performance data such as on and note off is formed (S6). Note-on is a command to instruct the sound source to start the formation of a new musical tone. When a new musical tone is input, the pitch of the input musical tone changes by more than a semitone, or when the level suddenly rises To form. Note-off is formed when the level of a musical sound that has been continuously input becomes equal to or lower than a predetermined value.

  When it is determined that the performance data is to be formed (S6: Yes), the performance data is formed (S7), and then whether or not the set musical tone mode is to speak a floor name corresponding to the pitch. Is determined (S8). As described above, in the present embodiment, the floor name can be set to be uttered by male voice or female voice corresponding to the pitch. If it is set to utter by floor name, if the performance data is note-on, the note number included in the note-on is converted to floor name (S9), and the converted floor name is uttered. An instruction is sent to the speech synthesizer 10 (S10).

  Whether the voice uttered by the voice synthesis is male voice or female voice is set by the user, an instruction is sent to the voice synthesizer 10.

  If it is determined in S8 that the utterance of the chord name is not set (S8: No), it is determined whether or not the utterance of the chord name is set (S11). If a chord utterance is set (S11: Yes), a chord formed by the input musical tone composed of a plurality of parts is detected (S12), and speech synthesis is performed so that the detected chord name is uttered. An instruction is sent to the apparatus 10 (S10). Note that chords may be uttered not when performance data is formed, but when the detected chords change or at the beginning of a measure.

If the chord utterance is not set in the determination process of S11 (S11: No), it is the case that the sound source 9 is set to generate a sound with a predetermined tone color, and the performance data formed in the process of S7 is used. It transmits to the sound source 9 (S1 3 ). The program change that specifies the timbre uttered by the sound source 9 is transmitted to the sound source 9 when the timbre is set by the user.

  If it is determined in the determination process of S5 that the timbre setting mode is not selected, the process in the style setting mode is executed (S20). Processing in this style setting mode will be described later with reference to FIG. If it is determined in the determination process of S6 that performance data is not to be formed (S6: No), and if the processes of S10 and S11 are terminated, the tone conversion reproduction process is terminated.

  This musical tone conversion / reproduction process is started every sampling period, but may be executed every time a plurality of amplitude values (for example, 32) are input by sampling.

  Next, a case where the style setting mode is set will be described with reference to FIG. FIG. 5 is a process executed when it is determined in step S5 of the flowchart shown in FIG. 4 that the timbre setting mode is not set.

  If the style setting mode is set, it is determined whether or not performance data such as note-on or note-off is formed based on whether or not the detected pitch, level, timbre, etc. have changed (S21). This determination process is the same as the process of S6 in the timbre setting mode.

  If it is determined that performance data is to be formed (S21: Yes), the performance data is formed (S22), and the performance data is sent to the sound source 9 (S23).

  When the performance data is transmitted to the sound source 9 and when it is determined that the performance data is not formed (S21: No), it is next determined whether or not the style has been changed (S24). When the performance style is changed by the user's operation, it is determined whether or not a timbre corresponding to the original timbre has been input by referring to the timbre conversion table set in the newly set style ( S25).

  If a timbre corresponding to the original timbre has been input, a program number corresponding to the timbre to be converted is acquired, and a program change having the program number is transmitted to the sound source 9 (S26).

  The program change is once transmitted to the sound source 9 when a performance style is set by the user, and is changed to a tone used in the changed performance style even when the user changes the performance style. Is sent to the sound source 9.

  As described above based on the embodiment, it is possible to change and enjoy music in real time by inputting a musical sound composed of a plurality of parts and changing the mode of the musical sound of any part. it can. Further, since the pitch of the input musical tone can be generated by the name of the floor, even the person who is not good at judging the pitch by listening can easily recognize the pitch of the musical tone. .

  Further, in the style setting mode for setting a style, the user can specify a music style of a musical tone to be inputted, and a plurality of timbres can be changed and reproduced by changing to a desired music style.
