  FIG. 3 is a diagram showing a correspondence relationship between the number keys of the mobile phone of FIG. 1 and the names of the twelve notes that are the basic sounds of the keyboard instrument. Each number key is arranged as shown in the lower diagram of FIG. FIG. 4 is an image diagram of the mobile phone in the assignment shown in FIG.

  In the lower diagram of FIG. 3, reference numeral 71 is an up key, reference numeral 72 is a down key, reference numeral 73 is a left key, reference numeral 74 is a right key, and reference numeral 75 is a center key. Processing using these direction keys 71 to 74 and the center key will be described in a mode processing function described later.

  In FIGS. 3 and 4, only the periphery of the number key of the mobile phone is displayed. In FIG. 4, note names are written on the number keys, which represent assigned note names, and numbers 0 to 9 and various symbols are actually written. .

  The assignment of timbres to the number keys shown in FIGS. 3 and 4 corresponds to the position of each key (operator) constituting the keyboard of the actual keyboard instrument shown in FIG. Specifically, first, the three white keys “Le”, “Le”, and “Mi” on the left side and the two black keys “Le b” and “Mi b” positioned above the first key are assigned to the first group. B1 and the three white keys “So”, “La”, “Shi” on the right side and the three black keys “So b”, “La b”, “Shi b” positioned above the second key Group B2.

  Next, the five keys belonging to the first group B1 are assigned to the lower number keys “8”, “9”, “*”, “0”, “#” (group A1), and Six keys belonging to the second group are allocated to six (group A2) of upper number keys “1” to “6”.

  Here, since the black key such as “Le” is positioned above the white key in the arrangement on the actual keyboard instrument, it is above group A1 and group A2, that is, number keys “1” to “3” and “8”. , “9”. Furthermore, for two pitch names that are in a semitone relationship (for example, “Le” and “Le b”), they are assigned to number keys (for example, “0” and “8”) that are adjacent vertically. Finally, the white key of “Fa” is assigned to the number key “7” between the groups A1 and A2.

  In this way, by assigning the pitch name corresponding to the key to the number key in accordance with the arrangement of the keys constituting the keyboard of the actual keyboard instrument, the user intuitively knows which pitch name is assigned to which number key. It becomes easy to imagine and can be performed easily.

  Also, the left side of the keyboard of the keyboard instrument (ie, the key belonging to group B1 in FIG. 5 and the white key of “Fa”) is played with the left hand, and the right side of the keyboard (ie, the key belonging to group B2 in FIG. 5) is played with the right hand. The number keys “1” to “6” located on the upper side of the mobile phone are played with the right hand, and the number keys “7” to “9”, “*”, “ By using “0” and “#” as areas for playing with the left hand, it is possible to perform a cross-cut performance using both hands. For this reason, a user who is familiar with the keyboard instrument is particularly likely to enter the performance using the mobile phone of the present invention.

  In the assignment of the pitch names of the keyboard musical instruments described above with reference to FIGS. 3 and 4, only the 12 basic sounds, that is, the sound of one octave can be reproduced. In the following, a mode switching function for realizing performance and transposition in a wide sound range exceeding one octave will be described.

  The mobile phone according to the present embodiment has three types of modes: a one-shot mode, a hold mode, and a transposition mode. Switching between the three types of modes is performed with the up direction key 71 and the down direction key 72 in FIG. 3, and setting values in each mode are switched with the left direction key 73 and the right direction key 74. In order to return to the default setting value in each mode, the center key 75 is pressed.

  In one-shot mode, press the number key while pressing the left arrow key 73 to lower the sound assigned to the number key by one octave, and press the number key while pressing the right arrow key 74 to assign to the number key. The generated sound can be raised one octave.

  In the hold mode, an octave shift is performed as many times as the left and right direction keys 73 and 74 are pressed, and the state is held. In the hold mode, when the left direction key 73 is pressed once, the sounds assigned to all the number keys are sounded from the original octave down by one octave from the original octave. Similarly, when the right direction key 74 is pressed once, the sounds assigned to all the number keys are sounded from the original octave up by one octave.

  If the left key 73 is pressed once and then the left key 73 is pressed once more, the sound assigned to the number key will be one octave down, and two octaves down from the original state. It becomes.

  Similarly, if the right key 74 is pressed once and the octave is raised one more time, then the right key 73 is pressed once again, the sound assigned to the number key will be raised one more octave, two octaves from the original state. It will be in the up state. To return to the original octave, press the center key 75.

  In the transposition mode, the transposition is performed by the number of times that the left and right direction keys 73 and 74 are pressed, and the state is maintained. In the transposition mode, when the left direction key 73 is pressed once, the sound assigned to the number key is sounded in a state where it is transposed down by one semitone. Similarly, when the right direction key 74 is pressed once, the sound assigned to the number key is pronounced in a state where it is transposed up by one semitone.

  If the left arrow key 73 is pressed once and the left key 73 is pressed once more, the sound assigned to the number key is shifted one more semitone below the original state. Transposes down a semitone.

  Similarly, when the right arrow key 74 is pressed once and transposed up by one semitone, and the right arrow key 73 is pressed once again, the sound assigned to the number key is transposed up by another semitone and the original key is transposed. The state is transposed up two semitones from the state. To return to the original state, the center key 75 is pressed.

  As described above, according to the present embodiment, when a keyboard instrument is played, operation keys (such as direction keys) other than the number keys of the mobile phone and the number keys are used in combination, and a wide range of performances and transpositions can be performed. . As for the octave, a default central octave may be defined in advance for each type of keyboard instrument corresponding to the timbre to be played, or the user may set the central octave.

Next, with reference to the flowchart of FIG. 6, the procedure for playing the tone of the keyboard instrument with the mobile phone of FIG. 1 will be described.
When the user designates the tone of the keyboard instrument to be played by operating the user interface 7 of the mobile phone (tone selection means) and instructs the start of the performance (step S601), the CPU 1 starts the setup for playing the keyboard instrument. (Step S602). At this time, for the sound source 4, for example, a channel for performance is set to one channel, and a program change message of the tone of the keyboard instrument designated by the user is transmitted.

  When the setup is completed, the user plays the keyboard instrument designated in step S601 by pressing or releasing the number key (step S603). During this time, the number key assigner 11 always scans which number key is pressed or released (step S604).

  If the user presses any number key, the number key assigner 11 determines that there is a pressed key (step S605: Yes), and the number key assigner 11 outputs information on the number key to the MIDI control module 12. The MIDI control module issues a note-on with a note number corresponding to the note name assigned to the input number key (step S606), and outputs it to the sound source 4. The sound source 4 generates musical tone data of a corresponding note number using the timbre tone color data indicated in the transmitted program change message.

  Thereafter, when the user releases the number key, the number key assigner 11 determines that there is a release key (step S607: Yes), and the number key assigner 11 outputs information on the number key to the MIDI control module 12. . The MIDI control module issues a note-off with a note number corresponding to the note name assigned to the input number key (step S608), and outputs it to the sound source 4. The sound source 4 stops generating musical tone data according to note-off.

  While the keyboard instrument is being played, Steps S604 to S608 are repeatedly executed, and each time the number key is pressed or released by the user, a note-on or note-off is issued to perform playback. Note that when playing a timbre with the sound source 4, note-on identification is necessary for all timbres, but the need for note-off identification depends on the timbre.

  Next, as a second embodiment of the present invention, a mobile phone that performs by assigning externally captured voice to number keys will be described.

  FIG. 7 is a block diagram showing the configuration of the mobile phone according to the second embodiment. In addition to the configuration of the first embodiment (FIG. 1), a microphone 21 (sound collecting means) that collects sound further. And an audio processing unit 22 that samples the audio signal at a predetermined sampling frequency. Here, the sound collected by the microphone may be any sound such as an actual instrument sound, human voice, animal voice, or object sound.

  The audio processing unit 22 samples an analog audio signal output from the microphone using a sampling clock having a predetermined frequency, and outputs digital audio waveform data. The CPU 1 creates timbre data that can be interpreted by the sound source 4 based on the voice waveform data, and stores it in the RAM 3 as one of the timbres.

  The user can select the timbre created from the voice signal collected by the microphone as the timbre assigned to the number key of the mobile phone in the timbre selection performed in step S601 in FIG. The sound source 4 sets the waveform phase to the tone (pitch) of the pressed number key and plays it.

  In this way, by assigning the timbre created based on the sound collected by the microphone to the number key of the mobile phone so that it can be played, the user can play various timbres by operating the number key. It is possible to perform with rich personality. In the above, the voice waveform data sampled by the microphone provided in the mobile phone is used, but the voice waveform data sampled at a place other than the mobile phone may be used.

  As mentioned above, although embodiment of this invention was explained in full detail, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included. For example, in the present embodiment, the performance by the timbre of the keyboard musical instrument has been described, but the present invention is not limited to the keyboard musical instrument, and can be applied to the performance by the timbre of the musical instrument having a plurality of operators.
