[0045] Hereinafter, with reference to the accompanying drawings, an electronic musical instrument according to one embodiment of the present disclosure will be described in detail. The embodiments shown below are examples of embodiments of the present invention, and the present invention is not limited to these embodiments. It should be noted that in the drawings referred to in this embodiment, the same reference numerals or similar reference numerals (reference numerals such as A, B, etc. are used to indicate the same parts or parts having the same function) are used to indicate the same parts or parts having the same function, and sometimes repeated descriptions are omitted.

[0046] [Structure of Electronic Musical Instruments]

[0047] Figure 1 This is a block diagram illustrating the structure of the electronic musical instrument 10 in the first embodiment of this disclosure. The electronic musical instrument 10 is a device that functions to output sound according to the performer's playing operation, and to output beats or accompaniment sounds according to pre-stored playing data or playing data obtained from an external source. In this embodiment, the case where the electronic musical instrument 10 is an electronic drum device will be described as an example.

[0048] The electronic musical instrument 10 includes a control unit 101, a sound source unit 102, a storage unit 103, a display unit 105, a setting input unit 111, a performance operation unit 113, and a communication I / F 115. These structures are interconnected via a bus 117.

[0049] The control unit 101 includes a CPU that controls the overall operation of the electronic musical instrument 10. The control unit 101 executes a control program stored in the storage unit 103 via the CPU, controlling the hardware constituting the electronic musical instrument 10 and implementing various functions within the instrument. These functions include the generation and output of sound signals based on user input to the setting input unit 111 and detection of operations performed on the playing operation unit 113.

[0050] The sound source unit 102 performs sound output control based on the instruction signal from the control unit 101. The sound source unit 102 includes a DSP (Digital Signal Processor). Detailed structure of the sound source unit 102 will be described later.

[0051] The memory 103 includes a ROM 105 and a RAM 107. The ROM 105 readablely stores various control programs executed by the CPU, various table data referenced by the CPU when executing the specified control programs, etc. Additionally, the ROM 105 stores sound waveform data for each type of the performance operation 113. The RAM 107 is used as working memory to temporarily store various data generated when the CPU executes the specified control programs. Furthermore, the RAM 107 also serves as memory for temporarily storing the currently executing control program and its associated data. Additionally, the storage unit 103 can also store various application programs and their associated data.

[0052] The display unit 105 is a display device such as a liquid crystal display or an organic EL display, and displays a screen to the user based on the control performed by the control unit 101.

[0053] The setting input unit 111 is an operating component used to receive setting operations for the electronic musical instrument 10 from the user, and is composed of various keys, buttons, rotary encoders, sliders, etc. When the display unit 105 is equipped with a touch panel, the touch panel can function as the setting input unit 111.

[0054] The performance control unit 113 is an operation unit used to receive performance operations from the performer on the electronic musical instrument 10. In this embodiment, the case where the electronic musical instrument 10 is an electronic drum device will be described. Therefore, the performance control unit 113 is composed of a snare drum pad that imitates a snare drum, a drum pad that imitates a floor drum, a footpad (foot pedal switch) that imitates a bass drum, a rhythm cymbal pad and a crash cymbal pad that imitate a rhythm cymbal and a crash cymbal, a hi-hat pad that imitates a hi-hat, and a foot pedal switch.

[0055] The Communication I / F115 is an interface for data communication with external devices. It can be wired or wireless, and can adopt any specification. The communication method can also be network communication. It should be noted that the functions of the storage unit 103 can also be implemented by an external device capable of communication via the Communication I / F115.

[0056] [Audio signal generation and output function]

[0057] The generation and output of sound signals, achieved by the control unit 101 of the electronic musical instrument 10 executing the control program stored in the storage unit 103, will be described. Part or all of the structure implementing the sound signal generation and output functions described below can also be implemented in hardware. In this embodiment, as an example, the implementation of the sound signal generation and output functions by the sound source unit 102 will be described.

[0058] Figure 2 This is a block diagram showing the structure of the sound source unit 102 in this embodiment. (Refer to...) Figure 2 The sound source unit 102 includes an acquisition unit 201, a performance tone generation unit 203, an adjustment unit 205, a first output unit 207, and a second output unit 209.

[0059] The acquisition unit 201 acquires a beat signal (first sound signal) Sclick and an accompaniment signal (second sound signal) Sback from an external source via a communication I / F 115. In this embodiment, the beat signal Sclick is a signal corresponding to the beat of a prescribed piece of music played by a performer. The accompaniment signal Sback is a signal corresponding to the accompaniment of the prescribed piece of music and / or the sound of a pre-recorded piece of music. Hereinafter, the accompaniment corresponding to the piece of music and the sound of the piece of music will be collectively referred to as accompaniment sound.

[0060] The acquisition unit 201 acquires the beat signal Sclick and the accompaniment signal Sback through their respective first input channels C1 and second input channels C2. The first input channel C1 can correspond to the L channel, and the second input channel C2 can correspond to the R channel. For example, the acquisition unit 201 can acquire the beat signal Sclick through the first input channel C1 and the accompaniment signal Sback through the second input channel C2. The acquisition unit 201 supplies the acquired beat signal Sclick and accompaniment signal Sback to the adjustment unit 205.

[0061] The performance tone generation unit 203 generates a performance tone signal Smusic based on the performance operation input by the performer to the performance operation unit 113. When a performance operation is input to the performance operation unit 113, event data corresponding to that performance operation is output. The performance tone generation unit 203 acquires the event data. The event data includes information indicating the type of performance operation unit 113 to which the performance operation was input, and the speed indicating the intensity of the performance operation input to the performance operation unit 113. The performance tone generation unit 203 generates the performance tone signal Smusic based on the acquired event data. Specifically, the performance tone generation unit 203 reads the sound wave data corresponding to the performance operation unit 113 from the storage unit 103 according to the type of performance operation unit 113, and adjusts the read sound wave data based on the speed. The performance tone generation unit 203 supplies the adjusted sound wave data as the performance tone signal Smusic to the adjustment unit 205.

[0062] The adjustment unit 205 receives the beat signal Sclick and the accompaniment signal Sback from the acquisition unit 201. Additionally, the adjustment unit 205 receives the performance signal Smusic from the performance tone generation unit 203. Furthermore, the adjustment unit 205 acquires setting volume information. The setting volume information indicates the volume of various sounds output from the electronic musical instrument 10, as specified by the user via the setting input unit 111. The setting volume information includes the setting volume information Vclick for the beat signal output from the headphones used by the performer, the setting volume information Vback1 for the accompaniment signal output from the headphones, the setting volume information Vmusic1 for the performance tone output from the headphones, the setting volume information Vmusic2 for the performance tone output from the speaker, and the setting volume information Vback2 for the accompaniment signal output from the speaker.

[0063] The adjustment unit 205 includes a first adjustment unit 205-1 and a second adjustment unit 205-2. The first adjustment unit 205-1 acquires the beat signal Sclick, the accompaniment signal Sback, the performance signal Smusic, the set volume information Vclick for the beat, the set volume information Vback1 for the accompaniment, and the set volume information Vmusic1 for the performance. Based on the set volume information Vclick, Vback1, and Vmusic1, the first adjustment unit 205-1 adjusts the volume balance of the beat signal Sclick, the accompaniment signal Sback, and the performance signal Smusic, and then mixes the beat signal Sclick, the accompaniment signal Sback, and the performance signal Smusic. The first adjustment unit 205-1 outputs the first output sound signal Sout1 generated by mixing the beat signal Sclick, the accompaniment signal Sback, and the performance signal Smusic to the first output unit 207.

[0064] The second adjustment unit 205-2 acquires the accompaniment tone signal Sback, the performance tone signal Smusic, the performance tone setting volume information Vmusic2, and the accompaniment tone setting volume information Vback2. Based on the setting volume information Vmusic2 and Vback2, the second adjustment unit 205-2 adjusts the volume balance of the accompaniment tone signal Sback and the performance tone signal Smusic, and then mixes the accompaniment tone signal Sback and the performance tone signal Smusic. The second adjustment unit 205-2 outputs the second output sound signal Sout2 generated by mixing the accompaniment tone signal Sback and the performance tone signal Smusic to the second output unit 209.

[0065] The first output unit 207 supplies the first output audio signal Sout1 to the headphones worn by the performer. The first output unit 207 supplies the first output audio signal Sout1 to the headphones via two different first channels CL1 and second channels CR1. The first channel CL1 can be the L channel corresponding to the left speaker of the headphones. The second channel CR1 can be the R channel corresponding to the right speaker of the headphones. That is, the beat signal Sclick and the accompaniment signal Sback, supplied via different channels (first input channel C1 and second input channel C2), are mixed and output from the L and R channels of the headphones. In other words, the beat signal Sclick, supplied via the first input channel C1 corresponding to the L channel, is output not only from the L channel of the headphones but also from the R channel, and the accompaniment signal Sback, supplied via the second input channel C2 corresponding to the R channel, is output not only from the R channel of the headphones but also from the L channel.

[0066] The second output unit 209 supplies the second output audio signal Sout2 to the speaker. The second output unit 209 supplies the second output audio signal Sout2 to the speaker (second output destination) via two different first channels CL2 and second channels CR2. The first channel CL2 can be a channel corresponding to a specific speaker. The second channel CR2 can be a channel corresponding to other speakers. That is, the accompaniment signal Sback and the performance signal Smusic supplied via the second input channel C2 are mixed and output from both channels of the speaker. In other words, the accompaniment sound based on the accompaniment signal Sback supplied via the second input channel C2 corresponding to the R channel is output not only from the other channel of the speaker but also from the first channel.

[0067] The above describes an example where the acquisition unit 201 acquires the beat signal Sclick through the first input channel C1 and the accompaniment signal Sback through the second input channel C2. However, it is also possible to acquire the accompaniment signal Sback through the first input channel C1 and the beat signal Sclick through the second input channel C2. The user can appropriately set the signals acquired through the first input channel C1 and the second input channel C2.

[0068] In the sound signal generation and output function described above by the sound source unit 102, the acquisition unit 201 supplies the beat signal Sclick and the accompaniment signal Sback, acquired through the first input channel C1 and the second input channel C2, respectively, to the adjustment unit 205 in mono mode. These signals are appropriately mixed in the adjustment unit 205 to generate a first output sound signal Sout1 and a second output sound signal Sout2. The generated first output sound signal Sout1 and second output sound signal Sout2 are output from the first output unit 207 and the second output unit 209, respectively, as stereo audio signals. However, this embodiment is not limited to this. For example, the acquisition unit 201 can convert the beat signal Sclick acquired through the first input channel C1 into a stereo audio signal and supply it to the adjustment unit 205. Similarly, the acquisition unit 201 can convert the accompaniment signal Sback acquired through the second input channel C2 into a stereo audio signal and supply it to the adjustment unit 205.

[0069] Figure 3 This is a conceptual diagram illustrating the flow of various sound signals input to the electronic musical instrument 10, mixed, and output. For example... Figure 3As shown, the first output sound signal Sout1, output from the first output unit 207 to the headphones, is generated by mixing the individual volumes of the beat signal Sclick, the accompaniment signal Sback, and the performance signal Smusic based on the set volume information Vclick, Vback1, and Vmusic1. Specifically, in the first adjustment unit 205-1, the beat signal Sclick is amplified by amplifier 301-a based on the set volume information Vclick. Similarly, the accompaniment signal Sback is amplified by amplifier 301-b based on the set volume information Vback1, and the performance signal Smusic is amplified by amplifier 301-c based on the set volume information Vmusic1. The beat signal Sclick amplified by amplifier 301-a and the accompaniment signal Sback amplified by amplifier 301-b are added by adder 303-a. Then, the amplified performance tone signal Smusic is added to the signal obtained by adding the beat tone signal Sclick and the accompaniment tone signal Sback through adder 303-b to generate the first output sound signal Sout1. The first output sound signal Sout1 is output to the headphones.

[0070] On the other hand, the second output sound signal Sout2 output from the second output unit 209 is generated by mixing the accompaniment sound signal Sback and the performance sound signal Smusic after adjusting their respective volumes based on the set volume information Vback2 and Vmusic2. Specifically, in the second adjustment unit 205-2, the accompaniment sound signal Sback is amplified by amplifier 301-d based on the set volume information Vback2, and the performance sound signal Smusic is amplified by amplifier 301-e based on the set volume information Vmusic2. The accompaniment sound signal Sback amplified by amplifier 301-d and the performance sound signal Smusic amplified by amplifier 301-e are added by adder 303-c to generate the second output sound signal Sout2. The second output sound signal Sout2 is then output to the speaker.

[0071] It should be noted that the direction of each sound signal input to the electronic musical instrument 10 of this embodiment and output after mixing is not limited to the reference direction. Figure 3 The direction of each audio signal is explained. When the user changes the settings of the signals obtained through the first input channel C1 and the second input channel C2, the direction of each audio signal output by mixing can be changed appropriately.

[0072] In the past, to make playing easier for performers, sometimes not only the beat notes but also the accompaniment notes were output to the performer's headphones. When both the accompaniment notes and beat notes are output from headphones, from the viewpoint of ease of playing the instrument, it is preferable to adjust the volume of the beat notes and the accompaniment notes separately to achieve a volume balance that is easy for the performer to play. In this case, the sound output from the headphones and the sound output from the speakers have different sound components and different volume balances; therefore, it is necessary to adjust the volume of each sound individually according to the output unit.

[0073] In the electronic musical instrument 10 of this embodiment described above, without using an external mixer, different sound signals (sclick signal Sclick, accompaniment signal Sback) input from the outside via different channels and the performance sound Smusic performed by the player can be easily mixed at the output section to the desired mixing balance by the player. Specifically, in the electronic musical instrument 10, the volume of the click, accompaniment, and performance sound output from the headphones worn by the player can be adjusted individually, and the volume of the accompaniment and performance sound output from the speakers can also be adjusted individually. That is, in the electronic musical instrument 10, the user can easily adjust the volume balance of each component contained in the sound output from the headphones and the volume balance of each component contained in the sound output from the speakers to mix the sound to a suitable mixing balance for the performance.

[0074] It should be noted that in the above-described embodiment, the case where the performer wears a headset when playing the electronic instrument 10 is described, but headphones can also be used instead of headsets.

[0075] Figure 4 This is a flowchart illustrating the sound reproduction method of the electronic musical instrument of this disclosure. As an example, the sound reproduction method performed by the electronic musical instrument 10 of the first embodiment will be described.

[0076] First, the electronic musical instrument 10 reads the settings made by the user (S501). Here, the settings refer to the settings made by the user before the sound reproduction by the electronic musical instrument 10 begins. For example, the settings include setting volume information Vclick, Vback 1, Vmusic1 for each sound component (slap signal Sclick, accompaniment signal Sback, and performance signal Smusic) included in the first output sound signal Sout1 output to the first output unit 207, and setting volume information Vback 2, Vmusic2 for each sound component (accompaniment signal Sback and performance signal Smusic) included in the second output sound signal Sout2 output to the second output unit 209. Furthermore, the settings made by the user include setting information for the input channels in the setting acquisition unit 201. The user can set the input channels according to the sending channel settings of the slap signal Sclick and accompaniment signal Sback input from the outside.

[0077] Next, the electronic musical instrument 10 performs setting processing based on the read settings (S502). Details of the setting processing will be described later. The electronic musical instrument 10 determines whether there is a sound reproduction instruction from the user (S503). If there is a sound reproduction instruction (S503: Yes), the electronic musical instrument 10 reproduces the sound (S504). Sound reproduction is achieved by referring to... Figure 2 The sound signal generation and output functions described herein are implemented by the sound source unit 102. Details regarding sound reproduction will be described later. In the absence of a sound reproduction instruction (S503: No), the electronic musical instrument 10 awaits a sound reproduction instruction from the user.

[0078] Figure 5 as well as Figure 6 It is shown Figure 4 The flowchart shows the process of setting up the device (S502). The electronic musical instrument 10 reads the settings input by the user via the setting input unit 111 (S501) and performs setting up based on the read settings. The setting up process (S502) can be executed by the control unit 101 or the sound source unit 102 of the electronic musical instrument 10.

[0079] First, based on the user-defined settings, it is determined whether the click signal Sclick is input through the first input channel C1 in the acquisition unit 201 (S502-1). If the click signal Sclick is input through the first input channel C1 (S502-1: Yes), the output destination of the signal acquired through the first input channel C1 is set to the first adjustment unit 205-1, and the output destination of the signal acquired through the second input channel C2 is set to the second adjustment unit 205-2 (S502-2). Next, based on the setting volume information Vclick, Vback1, and Vmusic1, the setting volume of the first output sound signal Sout1 output from the first output unit 207 is reflected (S502-3). In other words, based on the setting volume information Vclick, Vback1, and Vmusic1, the amplifier ( Figure 3 The amplification rate of amplifiers 301-a, 301-b, and 301-c in the amplifiers is then adjusted. Next, based on the set volume information Vback2 and Vmusic2, the set volume of the second output sound signal Sout2 output from the second output unit 209 is adjusted (S502-4). In other words, based on the set volume information Vback2 and Vmusic2, the amplifier (…) is set… Figure 3 The amplification of amplifiers 301-d and 301-e in the diagram. Here, the order of S502-3 and S502-4 can be reversed. It should be noted that, referring to... Figure 2 as well as Figure 3 The description of this embodiment is based on the setting process of S502-1 to S502-4 described above.

[0080] If no click signal Sclick is input through the first input channel C1 (S502-1: No), based on the user's settings, it is determined whether to input the click signal Sclick through the second input channel C2 in the acquisition unit 201 (S502-5). If the click signal Sclick is input through the second input channel C2 (S502-5: Yes), the output destination of the signal acquired through the second input channel C2 is set to the first adjustment unit 205-1, and the output destination of the signal acquired through the first input channel C1 is set to the second adjustment unit 205-2 (S502-6). Then, processing proceeds to S502-3.

[0081] If no click signal Sclick is input through the second input channel C2 (S502-5: No), it is determined whether a signal is input in stereo mode (S502-7). In this case, the input signal can be audio data. If a signal is input in stereo mode (S502-7: Yes), the output destination of the signal obtained in stereo mode is set to the first output unit 207 and the second output unit 209 (S502-8). Then, based on the settings made by the user, the set volume of the sound signal output from the first output unit 207 and the set volume of the sound signal output from the second output unit 209 are reflected (S502-9).

[0082] In stereo mode, if there is no input signal (S502-7: No), the output destination of the acquired signal is set based on a predetermined setting (S502-10). Then, processing proceeds to S502-9. Audio source 102 may include... Figure 2 The processing circuits of the sound source unit 102 shown have different structures, and the processing described above in S502-7 and beyond can also be handled by these other processing circuits.

[0083] Figure 7 It is shown Figure 4 The flowchart shown illustrates the sound reproduction process (S504). The sound reproduction process is performed by the sound source unit 102 of the electronic musical instrument 10. First, the beat signal Sclick and the accompaniment signal Sback are acquired from the outside (S504-1). Next, based on the performance operation input by the performer to the performance operation unit 113, the performance signal Smusic is generated (S504-2).

[0084] Next, the user-specified setting volume information is obtained via the setting input unit 111 (S504-3). Then, in the first adjustment unit 205-1, the click signal Sclick, the accompaniment signal Sback, and the performance signal Smusic are mixed to generate a first output sound signal Sout1, which is then output to the first output unit 207 (S504-4). Subsequently, in the second adjustment unit 205-2, the accompaniment signal Sback and the performance signal Smusic are mixed to generate a second output sound signal Sout2, which is then output to the second output unit 209 (S504-5). It should be noted that the processing order of S504-4 and S504-5 can be reversed or performed simultaneously.

[0085] <Second Implementation Method>

[0086] In the first embodiment described above, a case was described in which performance data (a click signal Sclick corresponding to a click note and an accompaniment signal Sback corresponding to an accompaniment note) input from the outside via different audio channels was mixed with the performance notes performed by the performer. However, the invention disclosed herein is not limited to this; performance data pre-stored in an electronic musical instrument may also be mixed with the performance notes performed by the performer and supplied to headphones and speakers worn by the performer with different volume balances.

[0087] [Structure of Electronic Musical Instruments]

[0088] The electronic musical instrument 10A of the second embodiment of this disclosure is a device that outputs sound according to the performer's playing operation, and outputs beat notes and accompaniment notes according to pre-stored playing data and playing data obtained from an external source. Similar to the first embodiment described above, this embodiment will be described using an electronic drum device as an example. The structure of the electronic musical instrument 10A in this embodiment is similar to that described above. Figure 1 The electronic musical instrument 10 described in the first embodiment is substantially the same, so the illustration is omitted.

[0089] Except for the storage unit 103a and the sound source unit 102a, the various structures of the electronic musical instrument 10A are similar to those in the reference. Figure 1 The structures of the electronic musical instrument 10 of the first embodiment described are generally the same, so the accompanying drawings showing the structures of the electronic musical instrument 10A are omitted, and repeated descriptions are omitted.

[0090] In this embodiment, the storage unit 103a of the electronic musical instrument 10A stores a beat signal Sclick (second sound signal Sclick) corresponding to a beat. The sound source unit 102a uses the beat signal Sclick corresponding to the beat stored in the storage unit 103a to generate and output a sound signal.

[0091] [Audio signal generation and output function]

[0092] The generation and output of sound signals, implemented by the control unit 101 of the electronic musical instrument 10A executing the control program stored in the storage unit 103a, will be described. Part or all of the structure implementing the sound signal generation and output functions described below can also be implemented in hardware. In this embodiment, as an example, the implementation of the sound signal generation and output functions by the sound source unit 102a will be described.

[0093] Figure 8 This is a block diagram showing the structure of the sound source unit 102a in this embodiment. (Refer to...) Figure 8The sound source unit 102a includes an acquisition unit 201a, a performance tone generation unit 203, an adjustment unit 205a, a setting unit 511, a first output unit 207, and a second output unit 209.

[0094] The acquisition unit 201a acquires performance data Dmusic from an external source. The acquisition unit 201a can acquire performance data Dmusic via communication I / F115. It should be noted that, although not shown, the acquisition unit 201a can acquire performance data Dmusic pre-stored in a USB memory. Performance data Dmusic includes timbre data representing the timbre setting of the electronic instrument 10A corresponding to the music being played, beat data representing the beat of the music being played, and audio data including an accompaniment tone signal Sback (first sound signal Sback) corresponding to the accompaniment tone of the music being played.

[0095] The acquisition unit 201a can acquire a performance dataset containing multiple performance data Dmusic corresponding to multiple musical pieces. The performance dataset may include multiple performance data Dmusic arranged in performance order. Additionally, the performance dataset may contain multiple performance data Dmusic arranged in order of difficulty of the musical pieces. Users can select and use the desired performance data Dmusic from the performance dataset.

[0096] Figure 9 This is a conceptual diagram used to illustrate the performance dataset. The performance dataset is user-editable and can also be pre-created by the user and saved in the storage unit 103 before using the electronic musical instrument 10A. Figure 9 The image shows 10 performance datasets, 601–610. It should be noted that the number of performance datasets is arbitrary.

[0097] Each of the performance datasets 601 to 610 includes multiple performance data. The structures of the performance datasets 601 to 610 are generally the same, so only performance dataset 601 will be described here. Performance dataset 601 consists, for example, multiple performance data 601-1 to 601-10.

[0098] Performance data 601-1 to 601-10 are data representing musical pieces played by electronic instrument 10A. The order of performance data 601-1 to 601-10 corresponds to the order in which they are played by electronic instrument 10A. The order of performance data 601-1 to 601-10 can be changed based on user input. As mentioned above, the order of performance data 601-1 to 601-10 can be either the order in which they are played by electronic instrument 10A or an order based on the difficulty of the performance.

[0099] Each of the performance data 601-1 to 601-10 may include a kit, tempo data, and audio data. A kit refers to timbre data that indicates the timbre settings of the electronic instrument 10A. For example, when performance data 601-1 is selected, the timbre of the performance notes of the electronic instrument 10A is determined based on the kits included in performance data 601-1. Tempo data indicates the tempo of the music corresponding to each of performance data 601-1 to 601-10. For example, when a beat response is output when performance data 601-1 is selected, the tempo of the beat response is determined based on the tempo data included in performance data 601-1. Furthermore, when reproducing performance data 601-1, the audio data included in performance data 601-1 is reproduced. The audio data includes the accompaniment tone signal Sback.

[0100] The kit, beat data, and audio data contained in each of the performance data sets 601-1 to 601-10 are different for each performance data set 601-1 to 601-10. By managing the kit, beat data, and audio data of each piece of music as separate performance data sets 601-1 to 601-10, it is easy to switch between pieces and change the order of pieces.

[0101] Additionally, the acquisition unit 201a acquires the beat signal Sclick corresponding to the beat from the storage unit 103a. The acquisition unit 201a supplies the acquired performance data Dmusic and the beat signal Sclick to the adjustment unit 205.

[0102] The performance tone generation unit 203 generates a performance tone signal Smusic based on a performance event input by the performer to the performance operation unit 113. When a performance event is input to the performance operation unit 113, event data corresponding to that performance event is output. The performance tone generation unit 203 acquires the event data. The event data includes information indicating the type of the performance operation unit 113 to which the performance event was input, and the speed indicating the intensity of the performance event input to the performance operation unit 113. The performance tone generation unit 203 generates the performance tone signal Smusic based on the acquired event data. Specifically, the performance tone generation unit 203 reads the sound wave data corresponding to the performance operation unit 113 from the storage unit 103a according to the type of performance operation unit 113, and adjusts the read sound wave data based on the speed. The performance tone generation unit 203 supplies the adjusted sound wave data as the performance tone signal Smusic to the adjustment unit 205a.

[0103] The setting unit 511 sets an offset period corresponding to the time difference between the output timing of the accompaniment sound signal Sclick and the output timing of the accompaniment sound signal Sback. The setting unit 511 sets the offset period based on user operations pre-input via the setting input unit 111. The setting unit 511 supplies offset data Doffset, representing the set offset period, to the adjustment unit 205a. It should be noted that when the output timing of the accompaniment sound signal Sback is synchronized with the output timing of the accompaniment sound signal Sclick, that is, when the output timings of the two sound signals are consistent, the setting performed by the setting unit 511 can be omitted.

[0104] The adjustment unit 205a receives performance data Dmusic and a beat signal Sclick from the acquisition unit 201a. Additionally, the adjustment unit 205a receives the performance tone signal Smusic from the performance tone generation unit 203. Furthermore, the adjustment unit 205a receives setting volume information. This setting volume information includes setting volume information Vclick for the beat output from the headphones, setting volume information Vback1 for the accompaniment output from the headphones, setting volume information Vmusic1 for the performance tone output from the headphones, setting volume information Vmusic2 for the performance tone output from the speaker, and setting volume information Vback2 for the accompaniment output from the speaker. The setting volume information is specified by the user via the setting input unit 111. Furthermore, the adjustment unit 205a receives offset data Doffset from the setting unit 511.

[0105] The adjustment unit 205a includes a first adjustment unit 205a-1 and a second adjustment unit 205a-2. The first adjustment unit 205a-1 acquires performance data Dmusic, offset data Doffset, performance signal Smusic, and set volume information Vclick, Vback1, and Vmusic1, including a beat signal Sclick, an accompaniment signal Sback, and beat data. The first adjustment unit 205a-1 adjusts the beat of the beat signal Sclick based on the beat data. The first adjustment unit 205a-1 mixes the beat signal Sclick, the accompaniment signal Sback, and the performance signal Smusic based on the set volume information Vclick, Vback1, Vmusic1, and offset data Doffset.

[0106] Furthermore, the first adjustment unit 205a-1 adjusts the timing of the output of the beat signal Sclick and the timing of the output of the accompaniment signal Sback based on the offset data Doffset. Specifically, the first adjustment unit 205a-1 aligns the reference point of the beat, i.e., the start point of the beat's reproduction, after an offset period based on the offset data Doffset from the start of reproduction. The user can determine the offset period based on the start point of the accompaniment's reproduction contained in the pre-acquired performance data Dmusic, and set the offset data Doffset for the determined offset period. The first adjustment unit 205a-1 outputs the first output sound signal Sout1, generated by mixing the beat signal Sclick, the accompaniment signal Sback, and the performance signal Smusic, to the first output unit 207. It should be noted that when generating and outputting the predicted number, the predicted number is traced back from the start point of the beat's reproduction.

[0107] Here, when the output timing of the accompaniment tone signal Sback is synchronized with the output timing of the beat response signal Sclisck, that is, when the output timings of the two sound signals are consistent, the adjustment of the timing of the output of the beat response signal Sclick and the timing of the output of the accompaniment tone signal Sback, as well as the adjustment of the beat of the beat response signal Sclick based on the beat data, performed by the first adjustment unit 205a-1, can be omitted.

[0108] The second adjustment unit 205a-2 acquires performance data Dmusic, including the accompaniment tone signal Sback, the performance tone signal Smusic, and setting volume information Vmusic2 and Vback2. Based on the setting volume information Vmusic2 and Vback2, the second adjustment unit 205a-2 mixes the accompaniment tone signal Sback and the performance tone signal Smusic. The second adjustment unit 205a-2 outputs the second output sound signal Sout2, generated by mixing the accompaniment tone signal Sback and the performance tone signal Smusic, to the second output unit 209.

[0109] The first output unit 207 supplies the first output audio signal Sout1 to the headphones worn by the performer. The first output unit 207 supplies the first output audio signal Sout1 to the headphones via two different first channels CL1 and second channels CR1. The first channel CL1 may be the channel corresponding to the left speaker of the headphones. The second channel CR1 may be the channel corresponding to the right speaker of the headphones.

[0110] The second output unit 209 supplies the second output audio signal Sout2 to the speaker. The second output unit 209 supplies the second output audio signal Sout2 to the speaker via two different first channels CL2 and second channels CR2. The first channel CL2 can be a channel corresponding to a specific speaker. The second channel CR2 can be a channel corresponding to other speakers.

[0111] In the electronic musical instrument 10A of this embodiment described above, without using an external mixer, the sound signal pre-stored in the electronic musical instrument 10A and the performance tone performed by the player can be easily mixed at the output section with the desired mixing balance. Specifically, in the electronic musical instrument 10A, the beat of the beat notes pre-stored in the electronic musical instrument 10A is adjusted based on performance data. Furthermore, in the electronic musical instrument 10A, the volume of the beat notes, accompaniment tone, and performance tone output from the headphones worn by the player can be adjusted independently, as can the volume of the accompaniment tone and performance tone output from the speaker.

[0112] In this embodiment, the sound signals pre-stored in the electronic musical instrument 10A include the beat-beat signal, but the sound signals pre-stored in the electronic musical instrument 10A are not limited to the beat-beat signal; the accompaniment signal corresponding to the accompaniment tone may also be pre-stored in the electronic musical instrument 10A. In this case, the user can select the corresponding accompaniment tone signal Sback based on the acquired performance data Dmusic.

[0113] It should be noted that in the above-described embodiment, the case where the performer wears a headset while playing the electronic instrument 10A is illustrated, but headphones can also be used instead of headsets.

[0114] Reference Figure 4 The sound reproduction method described can also be applied to the sound reproduction method performed by the electronic musical instrument 10A of the second embodiment. Figure 4 When the sound reproduction method shown is executed by the electronic musical instrument 10A of the second embodiment, the settings read by the electronic musical instrument 10A in step S501 include, in addition to the volume information Vclick, Vback1, Vmusic2, Vmusic1, and Vback2, offset data Doffset. Then, the electronic musical instrument 10A reproduces the sound (S504). The sound reproduction is achieved by referring to... Figure 5 The sound signal generation and output functions described herein are implemented by the sound source unit 102a. In the sound reproduction method executed by the electronic musical instrument 10A of the second embodiment, processing and... Figure 5 The settings and processing in the sound reproduction methods shown are different.

[0115] Figure 10 This illustrates the second embodiment. Figure 4 The flowchart shows the process of setting up the device (S502). The electronic musical instrument 10A reads the settings input by the user via the setting input unit 111 (S501) and performs setting up based on the read settings. The setting up process (S502) can be executed by the control unit 101 or the sound source unit 102a of the electronic musical instrument 10A.

[0116] First, based on the user's settings, it is determined whether audio data has been selected (S502a-1). That is, it is determined whether the selected performance data includes audio data. If audio data has been selected (S502a-1: Yes), based on the user's settings, it is determined whether the audio data and the beat response are synchronized (S502a-2).

[0117] When the audio data is synchronized with the beat (S502a-2; Yes), based on settings predetermined by the user, an offset period corresponding to the time difference between the output timing of the beat signal Sclisck and the output timing of the accompaniment signal Sback is set (S502a-3). Next, based on the beat data, an estimate is set (S502a-4). The estimate refers to the function of counting only a predetermined number of measures before reproducing the audio data. Here, the time from the start of the estimate to the start of the audio data reproduction can be calculated. In addition, settings for generating the estimate and for stopping the estimate can also be made here. For example, it can be set to stop the beat after counting a predetermined number of measures, or it can be set to continue playing the beat after counting. Alternatively, it can be set to stop the beat after the estimate.

[0118] If no audio data is selected in S502a-1 (S502a-1: No), and if the audio data is out of sync with the beat response in S502a-2 (S502a-2: No), the process proceeds to S502a-4.
