Description

  The present invention relates to an electronic musical instrument having a function capable of converting own performance data into a straight melody for a mobile terminal device.

  In conventional mobile terminal devices, by pressing the operation button of the terminal device, the user's favorite ringtone is input or the ringtone distribution site is accessed, where the ringtone data is downloaded and the incoming call is notified. It was used as a melody.

  However, for example, when an original melody is to be input, the user only has to input the incoming melody data by pressing the operation button, which requires very troublesome work.

  On the other hand, when downloading the incoming melody data, it is easy, but the original melody cannot be input.

  In addition, although it is possible to input a ring melody using a personal computer, it is often the case that the ring melody data is downloaded and then input to the mobile terminal device. Alternatively, there is a configuration in which an appropriate melody input interface screen is displayed on a personal computer screen and input is made with a mouse or the like. However, even in that case, such a mouse operation on the screen is required, and the operation is also troublesome.

  The present invention has been devised in view of the above problems, and it is intended to provide a configuration in which an electronic musical instrument can be used to easily input a user's favorite or original ringing melody to a mobile terminal device. It is.

Therefore, the present invention is an electronic musical instrument for generating a musical sound from a musical sound generating means based on at least a performance operation,
Data storage means for storing performance data based on performance operations and converted data after format conversion of the performance data;
Conversion condition setting means for setting conversion conditions for data format conversion,
Data conversion means for converting the performance data stored in the data storage means in accordance with the conversion conditions and storing the performance data in the data storage means;
Reproduction control means for reading out the converted data and generating a musical sound from the musical sound generating means of the electronic musical instrument;
It has a basic feature that it has data transfer means for reading the converted data and transferring it to the portable terminal device.

  According to the above configuration, a performance is performed using an electronic musical instrument, which is transferred and input to the mobile terminal device, so that it is possible to easily input a favorite or original ringing melody.

  That is, by playing the electronic musical instrument, the target melody is stored as performance data in the data storage means, and then conversion conditions for data format conversion are set using the conversion condition setting means. Then, the performance data is converted in format according to the conversion condition by the data conversion means and stored in the data storage means. Thereafter, using the reproduction control means, the converted data is read out, and a musical sound is generated from the musical sound generating means of the electronic musical instrument and is auditioned. If you do not like this, change the conversion conditions and perform the data format conversion again, or repeat the above operation from the first performance. Finally, the converted data is transferred to the portable terminal device using a data transfer means.

  If the data format is determined, the conversion condition set by the conversion condition setting means when converting the data format is the maximum data capacity (data size), number of pronunciations, number of channels, chords of the converted data. There are number, measure number, style, tone, effect, control change and so on. For example, depending on the model of the mobile terminal device, there is a maximum value of the data capacity for the incoming melody, and data exceeding this is basically not stored in the mobile terminal device, so the conversion condition is set here. It is necessary to keep it.

  The mobile terminal device includes not only a mobile phone but also a PDA or the like having a function such as calling something or an alarm indicating that time has come. In this case, the ringing melody and alarm melody are called incoming melody.

  In recent years, the data format has been standardized for ringtones.

  For example, GML, GM2, etc. have a data format composed of MIDI messages. As shown in FIG. 18, status bytes [MSB (bit 7) of 1 are 80H to FFH indicating the type of message. And a data byte representing the actual data [MSB (bit 7) is a byte with 0 as a numerical value from 00H to 7FH].

  In addition, in a data format called SMAF that defines a multimedia data format that can be played back on a mobile terminal device, as shown in FIG. 19, the data ID (for identification) and data size (length of the body part: in bytes) Are comprised of an 8-byte header part and an arbitrary-length data body part.

  Since GML and GM2 are basically the same data format as MIDI, in the above configuration, the musical sound generating means of the electronic musical instrument is used by the playback control means to generate a musical sound based on the converted data and to listen to it. it can.

  However, in the latter data format, it is not possible to audition the converted data using the musical sound generating means of the electronic musical instrument.

Accordingly, the invention of claim 2 is also an electronic musical instrument that generates a musical sound from a musical sound generating means based on at least a performance operation,
Another sound source for generating a musical sound according to a data format different from the musical sound generating means,
Data storage means for storing performance data based on performance operations and converted data after format conversion of the performance data;
Conversion condition setting means for setting conversion conditions for data format conversion,
Data conversion means for converting the performance data stored in the data storage means in accordance with the conversion conditions and storing the performance data in the data storage means;
Reproduction control means for reading the converted data and generating a musical sound from the other sound source;
It has a data transfer means for reading the conversion data and transferring it to the portable terminal device.

  In the above configuration, a sound source for generating a musical sound according to the converted data format is provided separately from the musical sound generating means provided in the electronic musical instrument. Therefore, the converted data converted in the latter data format is used for trial listening. At this time, the sound is read out by the reproduction control means, and based on this, a musical sound is generated from the above-mentioned another sound source (if another format format is adopted in the future, a separate sound source is also provided and data conversion is performed. Needless to say, the means should also be adapted to convert to that format.) Others are basically the same as the above configuration.

  In addition, each type of mobile terminal device (such as each family member) may enter their favorite ring melody, or each may input an original ring melody, depending on the model. The data format for melody data may be different. The configuration of claim 3 defines a configuration that can cope with such a case.

That is, the configuration of claim 3 is an electronic musical instrument that generates a musical sound from a musical sound generating means based on at least a performance operation,
Another sound source for generating a musical sound according to a data format different from the musical sound generating means,
Model setting means that can select the model of the mobile terminal device and thereby specify the data format at the time of data format conversion,
Data storage means for storing performance data based on performance operations and converted data after format conversion of the performance data;
Conversion condition setting means for setting conversion conditions for data format conversion,
Data conversion means for converting the performance data stored in the data storage means according to the selected model and conversion conditions, and storing the data in the data storage means;
Reproduction control means for reading out the converted data and generating a musical sound from the musical sound generating means or another sound source in accordance with the specified data format;
It has a data transfer means for reading the conversion data and transferring it to the portable terminal device.

  Here, model setting means is provided, and the data format at the time of data format conversion can be specified by selecting the model of the portable terminal device. Therefore, at the time of data format conversion by the data conversion means, the performance data is converted according to the selected model and conversion conditions.

  According to the electronic musical instrument of the first to third aspects of the present invention, it is possible to input a favorite or original ringing melody to the portable terminal device by playing the electronic musical instrument by himself using the electronic musical instrument. An excellent effect can be achieved in that troublesome work such as pressing or operating the mouse is not necessary.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a configuration of an electronic keyboard instrument 100 according to an embodiment of the present invention.

  The main body of the electronic keyboard instrument 100 can perform various setting processes (for example, a certain type of switch process) on a keyboard 115 (to be described later) and the player's electronic keyboard instrument, and display a setting state thereof. An operation panel 114 configured by a panel display and a data transfer external interface 71 included as a configuration of the present embodiment connected to the mobile phone 200 are provided.

  FIG. 2 is an explanatory diagram showing an internal circuit configuration of the electronic keyboard instrument 100. The electronic keyboard instrument 100 is connected to a CPU 111, a ROM 112, a RAM 113, a panel scan circuit 114 a, a keyboard scan circuit 115 a, a tone generation circuit 116, and a tone generator unit 10 other than the tone generation circuit 116 via a bus 110. ing.

  The CPU 111 reads the control program stored in the ROM 112 and controls the entire electronic keyboard instrument 100 while using the RAM 113 according to the read control program. Further, the CPU 111 reads and executes the processing program provided in the ROM 112, thereby configuring the data conversion unit 50 and the reproduction control unit 60 of the configuration of the embodiment of the present invention which will be described later, and processing according to these functions is performed. Will be done. The processing performed by the CPU 111 will be described in detail later with reference to the functional block configuration of FIG. 3 and the flowchart of FIG.

  The ROM 112 stores the above-described control program and various fixed data used by the CPU 111. The ROM 112 stores a plurality of tone color parameters for designating tone colors. One tone color parameter is used for designating a tone color of a predetermined range of a predetermined instrument sound. Each tone color parameter is composed of, for example, a waveform address, frequency data, envelope data, filter coefficients, and the like. Further, the ROM 112 has a conversion processing program for converting into a data format of incoming melody data, which differs depending on the model of the mobile phone 200 described later, based on the performance data when read by the CPU 111 and executed, and ancillary to the processing. A processing program for performing control processing for trial listening and transferring incoming melody data to a mobile phone is stored.

  The RAM 113 is used to temporarily store various data when the CPU 111 performs various processes. Specifically, the RAM 113 defines various registers, counters, flags, and the like for controlling the electronic keyboard instrument 100. The data storage unit 30 having the configuration of the embodiment of the present invention described later is also configured by the RAM 113.

  An operation panel 114 is connected to the panel scan circuit 114a. In response to an instruction from the operation panel 114, the instruction is transmitted to the CPU 111, and various setting processes can be performed as described above. Further, display data sent from the CPU 111 is sent to the screen on the operation panel 114, and a message (setting state, etc.) according to the display data is displayed on the screen.

  As described above, various setting processes can be performed on the operation panel 114, and the setting state and the like are displayed. As one of such functions, the performance data played by the user is used for the mobile phone 200. A ringtone conversion switch for converting to a ringtone is displayed. When the ringtone conversion switch is selected, after the performance data is input, the screen shown in FIG.

  In addition to these switches, for example, a volume switch, a tone color selection switch, a reverberation effect selection switch, and the like are provided. Since the operation panel 114 is composed of a panel display as described above, it is used as a display device for displaying various messages and mode setting states.

  The panel scan circuit 114a connected to the operation panel 114 scans each switch on the operation panel 114 in response to a command from the CPU 111. Then, panel data is created based on a signal indicating the open / closed state of each switch obtained by this scan. Each bit of the panel data corresponds to each of the above switches. For example, “1” represents a switch-on state and “0” represents a switch-off state. This panel data is used to determine whether or not each switch on the operation panel 114 has been pressed.

  A keyboard 115 having a plurality of keys is connected to the keyboard scanning circuit 115a, and the key depression state of the keyboard 115 is detected and output as performance data. That is, the keyboard scan circuit 115 a scans each key switch on the keyboard 115 in accordance with a command from the CPU 111. Then, performance data is created on the basis of the signal indicating the open / closed state of each key switch obtained by this scan. The performance data is composed of a bit string in which each key corresponds to 1 bit, and each bit represents that the key is being pressed, for example, “1” and the key is being released, “0”.

  The performance data is sent to the CPU 111 via the bus 110. The CPU 111 sends performance data, which will be described later, and data such as volume, tone color, and reverberation effect to the musical tone generation circuit 116 together. The musical sound generating circuit 116 is composed of a sound source that generates musical sounds based on performance data. The digital signal output from the tone generation circuit 116 is converted into an analog signal by the D / A conversion circuit 117, amplified by the amplifier 118, and the tone is output to the outside via the speaker 119.

  The tone generation circuit 116 is composed of a sound source having a channel (part) capable of simultaneously generating 32 sounds, and is equipped with a waveform memory (not shown) for reading predetermined tone color data. This waveform memory is constituted by a ROM, for example, and stores waveform data corresponding to each timbre parameter. The waveform data is created, for example, by performing pulse code modulation (PCM) on a musical sound signal generated based on a natural musical instrument sound. The musical performance data sent from the keyboard scanning circuit 115a is input to the musical tone generation circuit 116 under the control of the CPU 111, so that a musical tone waveform is output from the musical tone waveform. In 117, it is converted into an analog signal.

  This musical sound signal is amplified by the amplifier 118 and then supplied to the speaker 119. Thereby, it is converted into an acoustic signal by the speaker 119 and emitted.

  The tone generator 10 is provided to allow the sampled conversion data in the data format called SMAF in FIG. 19 to be auditioned. For example, an FM tone generator that can output a musical sound based on data in the data format such as SMAF. Composed.

  In addition, a direct data transfer external interface 71 is connected to the CPU 111. The data transfer external interface 71 is an interface to the outside of a data transfer unit 70 described later. The data transfer unit 70 controls the transmission and reception of incoming melody data between the CPU 110 and the external mobile phone 200. As this data transfer external interface 71, for example, USB, IEEE 1394, infrared transmission / reception circuit, etc. can be used according to the type of connected device, but generally used USB is used in this embodiment configuration. Yes.

  FIG. 3 is a block diagram showing functional blocks of the electronic keyboard instrument 100 configuration.

  As shown in the figure, the configuration of the electronic keyboard instrument 100 according to the present invention detects the key depression state of the keyboard 115, and the keyboard scan circuit 115a outputs the performance data, but the data different from the performance data format is shown.

A model setting unit 20 in which the data format is specified, a data storage unit 30 in which the performance data output based on the performance operation of the keyboard 115 and the converted data after the format conversion of the performance data are stored, and the data format A conversion condition setting unit 40 for setting conversion conditions at the time of conversion, and an operation stored in the data storage unit 30. The data is converted in format according to the selected model and conversion conditions, and the data conversion unit 50 stores the data in the data storage unit 30. The converted data is read out, and the tone generator circuit 116 or the above-described data is generated according to the data format specified by the model setting. A reproduction control unit 60 that generates musical sounds from the sound source unit 10 and a data transfer unit 70 that reads out the converted data and transfers them to the mobile phone 200 are provided.

  In addition, as described above, the configuration of this embodiment includes a configuration of a normal electronic keyboard instrument that receives performance data and causes the tone generation circuit 116 to generate a tone signal based on the set timbre parameter. Needless to say.

  The sound source unit 10 is composed of an FM sound source having a channel (part) capable of simultaneously producing at least six sounds, and the mobile phone 200 selected by the model setting unit 20 has only an FM sound source as a sound source. When the data converted by the data conversion unit 50 is data in the SMAF format, this is a configuration for listening to the data. The reproduction control unit 60, which will be described later, sends SMAF format conversion data and data such as volume, timbre, reverberation effect and the like together to the sound source unit 10, whereby an incoming melody is output from the speaker 119.

  The model setting unit 20 includes the operation panel 114, the panel scan circuit 114a, the CPU 111, and the ROM 112. The model setting unit 20 displays the model of the mobile phone 200 stored in the ROM 112 on the operation panel 114 and allows the player to select it. Thus, the corresponding conversion format stored in the ROM 112 is specified and stored in a register on the RAM 113.

  The data storage unit 30 includes the RAM 113, and performance data output based on the performance operation of the keyboard 115, and converted data after the performance data is format-converted by the data conversion unit 50. It is a configuration to be stored.

  The conversion condition setting unit 40 includes the operation panel 114, the panel scan circuit 114a, the CPU 111, and the ROM 112. The conversion condition setting unit 40 causes the operation panel 114 to display the maximum value of the incoming melody data, tone color data, and effect parameters stored in the ROM 112. By making the player select it, these data and parameters stored in the ROM 112 are used as conversion conditions and stored in a register on the RAM 113.

  The data conversion unit 50 includes a CPU 111 and a ROM 112, and the CPU 111 reads out and executes the conversion processing program stored in the ROM 112, whereby the performance data stored in the data storage unit 30 is converted into the RAM 113. The format is converted in accordance with the selected model (conversion format type) and conversion conditions stored in the register, and stored in the data storage unit 30.

  The playback control unit 60 is also composed of a CPU 111 and a ROM 112, and the CPU 111 reads out and executes the audition control processing program stored in the ROM 112, thereby reading out the conversion data and setting the model according to the model setting. An output destination (musical tone generation circuit 116 or sound source unit 10) of conversion data is determined, and a musical tone is generated from the musical tone generation circuit 116 or the sound source unit 10 in accordance with the data format specified by the model setting.

  The data transfer unit 70 includes a data transfer external interface 71 including the USB connector, and includes a CPU 111 and a ROM 112. The CPU 111 reads and executes a USB serial data transfer processing program stored on the ROM 112. The conversion data is read out and transferred to the mobile phone 200 as incoming melody data.

  Next, the operation of the electronic keyboard instrument will be described with reference to the flowchart of FIG. 4 and the screen display configurations of FIGS. It should be noted that all the processes shown in the flowchart are performed by the CPU 111.

  FIG. 4 is a flowchart showing a procedure of data conversion and transfer processing for the mobile phone 200 of the electronic keyboard instrument 100. First, the performer selects a ringtone conversion switch on the operation panel 114. Then, the performance data is input by manually pressing the keyboard 115 (step S101).

  As described above, since the ringtone conversion switch is selected, the performance data is simultaneously stored in the data storage unit 30 during the performance (step S102).

  When the performance data is stored, the model selection screen of the mobile phone 200 as shown in FIG. 5 is displayed, and the model setting is made by selecting the model of the mobile phone 200 that the performer wants to store as a ringing melody. Processing is performed (step S103). That is, the model setting unit 20 specifies a conversion format corresponding to the selected model stored in the ROM 112 (data format determination), and stores it in a register on the RAM 113.

  Thereafter, the conversion condition setting unit 40 displays screens for selecting the conversion conditions shown in FIGS. 6 to 8, and the player selects and sets the conversion conditions in accordance therewith, so that the conversion condition setting process is performed ( Step S104).

  FIG. 6 is an input screen for the data size of the incoming melody to be created. Here, the maximum data size is input. In recent years, some mobile phones 200 have a configuration in which an external storage medium such as a memory card can be mounted. If ringtone melody data is stored on the medium and can be used for a ringtone, the size is considerably large. Can be set.

  FIG. 7 is a screen for designating a tone color in a channel (six channels in the illustrated example) used in the sound source of the incoming melody. The number of channels is determined by the sound source of the mobile phone 200 to be stored as a ringing melody and the data format after conversion. This also applies to the tone colors that can be specified.

  FIG. 8 is a screen for designating the effect in the channel used for the sound source of the incoming melody. The types of effects that can be specified are determined by the sound source of the mobile phone 200 and the data format after conversion.

  When the above processing is completed, the operation panel 114 displays a screen for inquiring whether to perform data conversion. When the Yes button is selected for the screen, the operation panel 114 screen is displayed in FIG. The conversion processing screen is displayed as shown. The data conversion unit 50 reads the conversion format stored in the register of the RAM 113 and the various conversion conditions stored in the register, and also reads the performance data stored in the data storage unit 30. The performance data is format-converted according to the conversion format and conversion conditions and stored in the data storage unit 30 (step S105).

  The conversion process is performed to the end, and when the conversion process is completed (conversion success) (step S106; Y), the playback control unit 60 reads out and executes the control process program for listening on the ROM 112. Then, a playback mode screen as shown in FIG. 10 is displayed on the operation panel 114. Here, the audition process is performed by selecting “1. Play” or pressing the triangular button protruding to the right below (step S107). That is, the playback control unit 60 reads the converted data, determines the output destination of the converted data (musical sound generation circuit 116 or tone generator unit 10) by model setting, and follows the data format specified by the model setting. A musical sound is generated from the musical sound generation circuit 116 or the sound source unit 10.

  When the audition is completed, the data transfer unit 70 reads and executes the USB serial data transfer processing program stored on the ROM 112, and transfers the converted data as shown in FIG. When a screen asking whether to do so is displayed (step S108) and the Yes button is selected (step S108; Y), the screen of the operation panel 114 is transferred as shown in FIG. The screen changes. Then, the data transfer unit 70 transfers the converted data to the mobile phone 200 as incoming melody data (step S109). When the transfer is completed, a transfer completion screen as shown in FIG. 13 is displayed on the operation panel 114.

  If the conversion is not successful in step S106 (step S106; N), the data conversion unit 50 passes the processing to the conversion condition setting unit 40, and the screen of the operation panel 114 is optimized as shown in FIG. Changes to the processing screen. On this screen, a process for optimizing the number of chords and a process for optimizing the number of bars can be selected. Both processes can reduce the data capacity.

  If the process for optimizing the chord number is selected (step S110; Y), the chord number optimizing process is executed (step S111). This chord number optimization process is performed by, for example, leaving only the highest and lowest sounds and deleting other sounds when there are three or more chords in one channel, as shown in FIG. This reduces the number of data. During actual chord number optimization processing, the screen shown in FIG. 16 is displayed on the operation panel 114, and it is possible to select whether to optimize the number of chords of all channels or the number of chords of a specified channel. become.

  After completion of the chord number optimization process or when the process for optimizing the chord number is not selected (step S110; N), a screen for inquiring whether or not to optimize the bar number as shown in FIG. 17 is operated. When displayed on the panel 114 and processing for optimizing the number of measures is performed (step S112; Y), it is designated which measure number in the performance data is the first and which measure number is to be ended. By pressing the arrow button after specifying the end measure number, the measure number optimization process is executed (step S113).

  After the end of the measure optimizing process or when the process for optimizing the number of measures is not selected (step S112; N), the process returns to step S105 to perform subsequent processes such as data conversion.

  In step S108, after the audition is completed, a screen for inquiring whether conversion data can be transferred is displayed (step S108). When a No button is selected for the screen (step S108; N), Since a screen for inquiring whether or not to return to the conversion condition setting process is displayed (not shown), if selection is made to return to the conversion condition setting process (step S114; Y), the process returns to step S104, and the subsequent processes Is repeated. On the other hand, when the selection to return to the conversion condition setting process is not made (step S114; N), the process returns to step S101, and the performance data is input again from the beginning.

  According to the configuration of the present embodiment described above, a performance can be performed using the electronic keyboard instrument 100, and the performance data can be converted and transferred to the mobile phone 200 before being transferred to the mobile phone 200. If you don't like it, you can change the conversion conditions or start again from the beginning, so you can easily input your favorite or original ringtone.

  In addition, even if a mobile terminal device of a different model inputs each user's favorite ring melody (such as each family member) or tries to input an original ring melody, the model setting unit 20 is provided. Since the data format at the time of data format conversion can be specified by selecting the model of the mobile phone 200, at the time of data format conversion by the data conversion unit 50, the performance data is converted according to the selected model and conversion conditions.

  In addition to the musical tone generation circuit 116 provided in the electronic keyboard instrument 100, the tone generator unit 10 is provided for generating musical sounds according to the converted data format. Therefore, the performance data format format of the electronic keyboard instrument 100 is provided. With respect to the converted data converted into a data format different from the above, a musical sound is generated from the other sound source unit 10 by the reproduction control unit 60 at the time of trial listening.

  It should be noted that the electronic musical instrument of the present invention is not limited to the illustrated examples described above, and it is needless to say that various modifications can be made without departing from the scope of the present invention.
