[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-267791 Summary of the Invention [Problem to be solved by the invention]

[0005] A user may change settings such as tone color while playing. In the case of a mechanical switch, the user can change the setting at the correct timing by placing their finger on the mechanical switch in advance and pressing the mechanical switch at the desired timing. On the other hand, with the touch switch described in Patent Document 1, the operation is accepted and the setting changes, for example, just before the finger touches the switch. Because the user cannot place their finger on the touch switch in advance, it is even more difficult to change the setting at the correct timing.

[0006] That is, the performance device described in Patent Document 1 has room for improvement in terms of accepting operations at the timing intended by the user.

[0007] In view of the above circumstances, an embodiment of the present disclosure aims to provide a performance device, method, and program that can accept operations at the timing intended by the user. [Means for solving the problem]

[0008] A performance device according to an embodiment of the present disclosure includes at least one processor, which, when a user continues to touch a touch-operable control for a set time and then slides the touched portion of the control on the control, switches a first setting to one of a plurality of second settings depending on the speed at which the touched portion is slid, and when the user releases his / her touch on the control before the set time has elapsed, switches the first setting to the next setting from the plurality of settings. [Effects of the Invention]

[0009] According to one embodiment of the present disclosure, a performance device, method, and program are provided that can accept operations at the timing intended by the user. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] The following description relates to a performance device, method, and program according to an embodiment of the present disclosure. Common or corresponding elements are denoted by the same or similar reference numerals, and duplicate descriptions will be appropriately simplified or omitted.

[0012] The electronic musical instrument 1 is an example of a musical performance device, such as an electronic keyboard. The electronic musical instrument 1 may be an electronic keyboard instrument other than an electronic keyboard, such as an electronic piano. The electronic musical instrument 1 may also be another type of electronic musical instrument, such as an electronic percussion instrument, an electronic wind instrument, or an electronic string instrument.

[0013] The performance device according to the present disclosure is not limited to the electronic musical instrument 1. The performance device may be, for example, an information processing device on which a musical instrument app that reproduces the electronic musical instrument 1 is installed. Illustratively, the performance device may be a smartphone, tablet terminal, or laptop (Personal Computer) on which such a musical instrument app is installed.

[0014] The electronic musical instrument 1 is a computer, and its hardware configuration includes a processor 10, RAM (Random Access Memory) 11, flash ROM (Read Only Memory) 12, an external connection interface 13, a keyboard 14, a switch panel 15, a key scanner 16, LEDs (Light Emitting Diodes) 17, a driver 18, an LCD (Liquid Crystal Display) unit 19, a sound source LSI (Large Scale Integration) 20, a D / A converter 21, and an amplifier 22. The various components of the electronic musical instrument 1 are connected via a bus 23.

[0015] The processor 10 reads out the programs and data stored in the flash ROM 12. The processor 10 controls the electronic musical instrument 1 in an overall manner by using the RAM 11 as a work area.

[0016] The processor 10 may be, for example, a single processor or a multi-processor, and includes at least one processor. When multiple processors are included, the processor 10 may be packaged as a single device, or may be configured as multiple devices that are physically separated within the electronic musical instrument 1. The processor 10 may be called, for example, a control unit, a CPU (Central Processing Unit), an MPU (Micro Processor Unit), or an MCU (Micro Controller Unit).

[0017] The RAM 11 temporarily stores data and programs, and stores various programs and data read from the flash ROM 12.

[0018] The flash ROM 12 is a non-volatile semiconductor memory such as a flash memory, an EPROM (Erasable Programmable ROM), or an EEPROM (Electrically Erasable Programmable ROM). The flash ROM 12 stores a control program 12A. The processor 10 executes the control program 12A to perform various processes according to an embodiment of the present disclosure.

[0019] The external connection interface 13 is, for example, an interface that, under the control of the processor 10, inputs and outputs MIDI data (MIDI messages) to and from an external MIDI (Musical Instrument Digital Interface) device in a serial format.

[0020] The keyboard 14 has 88 keys that are operators. Specifically, the keyboard 14 has 52 white keys and 36 black keys. Each key is associated with a different pitch. The electronic musical instrument 1 produces musical tones in response to the depression of a key on the keyboard 14. The number of keys on the keyboard 14 is not limited to 88. The keyboard 14 may have another number of keys, such as 61 keys or 76 keys.

[0021] The switch panel 15 includes various controls for operating the electronic musical instrument 1. The various controls include controls corresponding to various functions such as power, recording, play / stop, tone adjustment, tone selection, and sound effects (vibrato, pitch bend, etc.). The tone selection control included in the switch panel 15 is referred to as a "selection switch 15A."

[0022] The key scanner 16 monitors key presses and releases on the keyboard 14. For example, when the key scanner 16 detects a key press by the user, it outputs a key press event to the processor 10. The key press event includes information about the pitch of the key related to the key press (key number). The key number is also called a key number, a MIDI (Musical Instrument Digital Interface) key, or a note number. The pitch is also called a note.

[0023] In this embodiment, a separate means is provided for measuring the key pressing speed (velocity), and the velocity measured by this means is also included in the key pressing event. For example, multiple contact switches are provided for each key. The velocity is measured based on the difference in the time that each contact switch remains conductive when the key is pressed. Velocity can be considered a value that indicates the strength of the key pressing operation, and also a value that indicates the loudness (volume) of the musical sound.

[0024] The LED 17 is an example of a light emitting unit. The LED 17 is driven and controlled by the processor 10 via the driver 18. The LED 17, under the control of the processor 10, causes the selection switch 15A to emit light.

[0025] The LCD unit 19 includes an LCD and a driver. When the driver drives the LCD in accordance with a control signal from the processor 10, a screen corresponding to the control signal is displayed. The LCD may be replaced with a display device such as an organic EL (Electro Luminescence) display.

[0026] The waveform data is stored in flash ROM 12 or another memory (not shown). This waveform data is loaded into RAM 11 during startup of electronic musical instrument 1 so that musical tones are quickly generated in response to key presses. When key scanner 16 detects a key press, processor 10 instructs sound source LSI 20 to read corresponding waveform data from the waveform data loaded into RAM 11. The waveform data to be read is determined, for example, by the tone color selected by the user and the key press event.

[0027] The tone generator LSI 20 generates musical tones based on waveform data read from the RAM 11 under the instruction of the processor 10. The tone generator LSI 20 has, for example, 128 generator sections and can simultaneously generate up to 128 musical tones. In this embodiment, the processor 10 and the tone generator LSI 20 are configured as separate processors, but in another embodiment, the processor 10 and the tone generator LSI 20 may be configured as a single processor.

[0028] The digital musical sound data generated by the sound source LSI 20 is converted into an analog signal by a D / A converter 21, amplified by an amplifier 22, and output from, for example, a line-out terminal. For example, the musical sound is reproduced by a speaker connected to the line-out terminal.

[0029] In this way, the electronic musical instrument 1 produces musical tones in response to keyboard operations (an example of user operations on controls).

[0030] In this embodiment, the various operators included in switch panel 15 are configured as capacitance switches to improve design, durability, waterproofness, dustproofness, etc. The various operators included in switch panel 15 are not limited to capacitance switches, and may be configured as other types of touch switches, such as resistive switches or infrared switches.

[0031] There may be cases where a user wants to change a setting (for example, tone) at a specific timing while a piece of music is being played. With a mechanical switch, the user can change the tone at the exact timing by placing their finger on the mechanical switch in advance and pressing the mechanical switch at the desired timing.

[0032] However, in this embodiment, the selection switch 15A is configured as a touch switch. With a touch switch, an operation is accepted and the tone changes immediately before or at the moment of touch. Because the user cannot place their finger on the touch switch in advance, it is difficult to change the tone at the correct timing. Therefore, the electronic musical instrument 1 according to this embodiment is suitably configured to accept an operation at the timing intended by the user.

[0033] A method for operating the selection switch 15A will be described with reference to Fig. 3. The hand shown in Fig. 3 shows the user touching the selection switch 15A. The outline arrow indicates the movement (slide) of the finger touching the selection switch 15A.

[0034] The selection switch 15A is an example of a touch-operable operator. The selection switch 15A is a capacitance switch in which a plurality of electrodes are arranged side by side. In this embodiment, as shown in Fig. 3, four electrodes 150a to 150d are arranged side by side in the longitudinal direction (an example of a first direction) of the selection switch 15A.

[0035] It should be noted that any reference to an element using a designation such as "first," "second," etc., used in this disclosure does not generally limit the quantity or order of those elements. These designations are used for convenience to distinguish between two or more elements. Thus, reference to a first and a second element does not imply, for example, that only two elements are employed, that the first element must precede the second element, etc.

[0036] When a user brings a finger close to the selection switch 15A (more specifically, an electrode), electrostatic induction occurs between the finger and the electrode, causing a change in the capacitance of the electrode. When the user places a finger on the selection switch 15A (e.g., electrode 150a), the capacitance of electrode 150a reaches a peak.

[0037] Fig. 4 is a diagram showing changes in capacitance at each of electrodes 150a to 150d when a user slides their finger over selection switch 15A. In Fig. 4, the vertical axis represents the capacitance of the electrode (unit: pF). The horizontal axis represents time (unit: sec). Reference symbols 154a, 154b, 154c, and 154d represent the capacitance of electrodes 150a, 150b, 150c, and 150d, respectively.

[0038] For example, when a user brings a finger closer to electrode 150a, capacitance 154a of electrode 150a gradually increases and exceeds threshold value TH, as shown in Fig. 4. At time T1, when the user's finger touches electrode 150a, capacitance 154a reaches a peak.

[0039] When the user slides their finger on selection switch 15A in the direction of the outline arrow (see FIG. 3), the distance between the finger and electrode 150a increases. As the distance between the finger and electrode 150a increases, capacitance 154a of electrode 150a decreases. At time T2, capacitance 154a falls below threshold TH and eventually becomes zero.

[0040] Meanwhile, the distance between the finger and electrode 150b decreases. As the distance between the finger and electrode 150a decreases, the capacitance 154b of electrode 150b increases and exceeds the threshold value TH. The capacitance 154b reaches a peak when the user's finger is positioned over electrode 150b. As the user's finger passes over electrode 150b and moves away from electrode 150b, the capacitance 154b gradually decreases. The capacitance 154b falls below the threshold value TH and eventually becomes zero.

[0041] Similarly, capacitance 154c of electrode 150c and capacitance 154d of electrode 150d gradually increase in response to the movement of the user's finger (slide operation), reach a peak, and then gradually decrease to zero.

[0042] When the user slides his / her finger from one end (near electrode 150a) to the other end (near electrode 150d) on selection switch 15A, the capacitances 154a to 154d of electrodes 150a to 150d change in sequence, drawing a mountain-like curve, as shown in FIG.

[0043] Based on such changes in capacitances 154a to 154d, processor 10 detects an operation (slide operation) in which the user slides his / her finger (an example of a part touching an operator) in the longitudinal direction (an example of a first direction) of selection switch 15A.

[0044] Processor 10 does not accept an operation on selection switch 15A the moment the user places his / her finger on selection switch 15A. Processor 10 accepts an operation on selection switch 15A when the user places his / her finger on selection switch 15A for a while and then performs a sliding operation.

[0045] That is, the user can change the tone color by placing a finger on the selection switch 15A and sliding the finger at the desired timing. As with a mechanical switch, the user can place a finger on the selection switch 15A in advance, so the user can easily change the tone color at the correct timing, for example, while playing a piece of music.

[0046] More specifically, the processor 10 changes one or both of the tone color and the effect (an example of a setting) according to the sliding speed of the user's finger on the selection switch 15A. For convenience, this sliding speed is denoted by the symbol SS.

[0047] Exemplarily, if the slide speed SS (unit: m / s) is within the first range (0.2 < SS < 1.0), the processor 10 changes the timbre to timbre A (for example, piano). If the slide speed SS is within the second range (0.1 < SS ≤ 0.2), the processor 10 changes the timbre to timbre B (for example, organ). If the slide speed SS is within the third range (0.667 < SS ≤ 0.1), the processor 10 changes the timbre to timbre C (for example, guitar).

[0048] The processor 10 measures the moving speed of the finger from near the start of the slide operation to near the end as the slide speed SS. Exemplarily, the processor 10 calculates the slide speed SS starting from the point when the capacitance 154a of the electrode 150a falls below the threshold value TH (in the example of FIG. 4, time T2) and ending at the point when the capacitance 154d of the electrode 150d exceeds the threshold value TH (in the example of FIG. 4, time T3). That is, the processor 10 calculates the slide speed SS during the period P1 illustrated in FIG. 4.

[0049] More specifically, the processor 10 obtains the slide speed SS by dividing the slide operation amount by the period P1 (in other words, the time from the start point to the end point). The slide operation amount is, for example, the distance between the electrode corresponding to the start point and the electrode corresponding to the end point. In the example of FIG. 4, the distance between the center position of the electrode 150a corresponding to the start point and the center position of the electrode 150d corresponding to the end point is the slide operation amount.

[0050] As a supplement, the period P1 for calculating the slide speed SS is not limited to the example shown in FIG. 4. For example, when the user's finger is placed near the electrode 150b, the point when the capacitance 154b of the electrode 150b falls below the threshold value TH becomes the start point when calculating the slide speed SS. When the user's finger is placed near the electrode 150c, the point when the capacitance 154c of the electrode 150c falls below the threshold value TH becomes the start point when calculating the slide speed SS.

[0051] When the user's finger is released near the electrode 150b, the point at which the capacitance 154b of the electrode 150b exceeds the threshold value TH becomes the end point when calculating the slide speed SS. When the user's finger is released near the electrode 150c, the point at which the capacitance 154c of the electrode 150c exceeds the threshold value TH becomes the end point when calculating the slide speed SS.

[0052] In this embodiment, the time region where the speed change is large is excluded in calculation. Thereby, the calculation accuracy of the slide speed SS is improved. The time region where the speed change is large is, for example, immediately after the finger starts to accelerate (in the example of FIG. 4, between time T1 and time T2), and immediately before the finger finishes decelerating (in the example of FIG. 4, between time T3 and the time T4 when the touch is released).

[0053] If 0.1 < P1 (sec) < 0.5, since the slide speed SS falls within the first range, the tone color is changed to tone color A. If 0.5 ≤ P1 (sec) < 1.0, since the slide speed SS falls within the second range, the tone color is changed to tone color B. If 1.0 ≤ P1 (sec) < 1.5, since the slide speed SS falls within the third range, the tone color is changed to tone color C.

[0054] The longitudinal direction of the selection switch 15A coincides with the direction in which each key of the keyboard 14 is arranged. The user facing the electronic musical instrument 1 can change the tone color with a simple operation of dragging a finger from left to right on the selection switch 15A.

[0055] Incidentally, the selection switch 15A is located slightly to the left of the center of the electronic musical instrument 1. The user can, for example, operate the selection switch 15A with the left hand while playing a melody with the right hand. The user can easily change the tone color during performance.

[0056] If the longitudinal direction of the selection switch 15A is too long, the required sliding distance becomes long, and operability deteriorates. If the longitudinal direction of the selection switch 15A is too short, the number of electrodes that can be installed becomes small, making it difficult to detect the sliding operation. Taking these factors into consideration, the longitudinal direction of the selection switch 15A is set to, for example, about 100 mm to 130 mm. The width of the electrodes is slightly smaller than the width of the user's finger.

[0057] A plurality of LEDs 17 are arranged corresponding to the electrodes 150a to 150d, respectively. In this embodiment, as shown in Fig. 3, four LEDs 17a to 17d are arranged side by side in the longitudinal direction (an example of the first direction) of the selection switch 15A.

[0058] When the user's finger is placed on the selection switch 15A for a while (in other words, when the user's touch on the selection switch 15A, which is an example of an operator, continues for a predetermined time (an example of a set time)), the processor 10 causes the LED 17 to light up in time with the set tempo.

[0059] Specifically, processor 10 causes LEDs 17a, 17b, 17c, and 17d to emit light in sequence in accordance with the tempo being set. Processor 10 causes LEDs 17a to 17d (an example of a plurality of light-emitting elements aligned in a first direction) to emit light in sequence in accordance with the tempo being set, from LED 17a (an example of a light-emitting element located at the end) to LED 17d (an example of a light-emitting element located at the end opposite to the end).

[0060] As an example, when the BPM (Beats Per Minute) is 120, the processor 10 causes the LEDs 17a to 17d to emit light in sequence at 0.5 second intervals. When up to the LED 17d has emitted light, the processor 10 turns off all of the LEDs 17a to 17d and then causes the LEDs 17a to 17d to emit light in sequence at 0.5 second intervals again. The processor 10 repeats this light emission control.

[0061] The blinking of the light by the LEDs 17a to 17d acts as a visual metronome, allowing the user to gauge the timing of changing the tone, for example, while visually checking this optical metronome.

[0062] Furthermore, by sequentially lighting the light from the left region (electrode 150a) to the right region (electrode 150d) within selection switch 15A, the user sees the light spreading from the left region to the right region within selection switch 15A. Seeing this light, the user can intuitively understand that the direction of the slide operation is from left to right. In other words, such light also serves as an operation guide.

[0063] The processing executed by the processor 10 in one embodiment of the present disclosure will be described with reference to Fig. 5. For example, when the power supply of the electronic musical instrument 1 is turned on, the processing shown in Fig. 5 starts to be executed.

[0064] The steps of the flowcharts shown in the present embodiment may be reordered to the extent that they are consistent. For example, although the present disclosure presents the processing of various steps using an exemplary order, the order is not limited to the presented order. Furthermore, the steps of the flowcharts shown in the present embodiment may be executed in parallel or in parallel to the extent that they are consistent.

[0065] As shown in FIG. 5, processor 10 executes an initialization process (step S101). In the initialization process, each component is initialized. In the initialization process, the operation mode of selection switch 15A is set to the normal mode. In the normal mode, each time selection switch 15A is tapped, the tone changes in a predetermined order (for example, in the order of tone A, B, C, etc.).

[0066] Processor 10 executes switch processing (step S102). In the switch processing, the operation states of various controls on switch panel 15 are acquired. For example, volume information, tone information, and the like are acquired.

[0067] The processor 10 executes function processing (step S103), in which a function corresponding to the operation state of each of the controls acquired in step S102 is executed.

[0068] The processor 10 determines whether the selection switch 15A has been touched by the user (step S104). If the selection switch 15A has not been touched (step S104: NO), the processor 10 returns to the switch processing of step S102.

[0069] If the selection switch 15A is touched (step S104: YES), the processor 10 determines whether this touch continues for a predetermined time (one second, for example, which is an example of a set time) (step S105).

[0070] When the selection switch 15A is tapped (in other words, the user releases his / her touch on the selection switch 15A before a predetermined time has elapsed) (step S105: NO), the processor 10 changes the tone in a predetermined order (step S106). For example, the processor 10 changes the tone in the order of tone A, B, C, etc., each time the selection switch 15A is tapped. The processor 10 executes switch processing (step S102) and function processing (step S103) to reflect the change in tone (set the tone to the changed tone). In other words, the user can change the tone by tapping the selection switch 15A at the desired timing.

[0071] In this way, when selection switch 15A is tapped (in other words, when the user releases their touch on selection switch 15A, which is an example of an operator, before the set time has elapsed, the moment the touch is released), processor 10 accepts the operation on selection switch 15A and changes the tone (executes an example of a first process). More specifically, processor 10 switches, for example, the current tone (an example of a first setting) to the next setting (the next tone in a predetermined order) among a plurality of settings (a plurality of types).

[0072] If the selection switch 15A is touched continuously for a predetermined time (step S105: YES), the processor 10 transitions the operation mode of the selection switch 15A to the standby mode (step S107). More specifically, the processor 10 checks the capacitances 154a to 154d, and if it detects that the touch position has not moved continuously for a predetermined time, it transitions the operation mode of the selection switch 15A to the standby mode. In the standby mode, when the user slides their finger placed on the selection switch 15A at the desired timing, the tone changes. In the standby mode, the LED 17 lights up in time with the tempo.

[0073] The processor 10 controls the light emission of the above-mentioned LEDs 17a to 17d (step S108).

[0074] The processor 10 determines whether a slide operation has been performed (step S109). If the touch is released (step S110: YES) without a slide operation being performed (step S109: NO), the processor 10 changes the tone color in a predetermined order (step S111), similar to step S106.

[0075] Next, processor 10 transitions the operation mode of selection switch 15A to the normal mode (step S114), and returns to the switch processing of step S102. Processor 10 executes the switch processing (step S102) and the function processing (step S103) to reflect the change in the timbre (set the timbre after the change).

[0076] When a slide operation is performed (step S109: YES), the processor 10 calculates the slide speed SS (step S112). The processor 10 changes the tone color to one that corresponds to the calculated slide speed SS (step S113). The user can change the tone color to a desired one by performing a single slide operation, without performing multiple operations (for example, multiple tap operations).

[0077] Processor 10 transitions the operation mode of selection switch 15A to the normal mode (step S114), and returns to the switch processing of step S102. Processor 10 executes the switch processing (step S102) and the function processing (step S103) to reflect the change in the tone color (set the tone color after the change).

[0078] In this way, when a slide operation (an example of a first method) is performed on selection switch 15A after the user's finger has been placed on selection switch 15A for a while (in other words, after the user's touch on selection switch 15A, which is an example of an operator, has continued for a set time), processor 10 accepts the operation on selection switch 15A and changes the tone (executes an example of a first process). Additionally, when a slide operation is performed on selection switch 15A (in other words, when the touched part of the operator is slid on the operator), processor 10 switches the first setting (e.g., the current tone) to one of a plurality of second settings (e.g., a tone different from the current tone) according to the slide speed SS (in other words, the speed at which the touched part is slid).

[0079] The above is a description of exemplary embodiments of the present disclosure. The embodiments of the present disclosure are not limited to those described above, and various modifications are possible within the scope of the technical idea of ​​the present disclosure. For example, the embodiments of the present disclosure also include appropriate combinations of embodiments explicitly shown as examples in the specification or obvious embodiments.

[0080] The operation for changing the tone is not limited to a slide operation, but may be another operation such as a double tap.

[0081] The processor 10 may illuminate the LED 17 among the LEDs 17a to 17d that corresponds to the touch position on the selection switch 15A. For example, when the user slides his / her finger on the selection switch 15A, the LEDs 17 corresponding to the slide position illuminate in order.

[0082] For example, the user can visually grasp the speed at which the sequentially emitting LEDs 17 are switched (in other words, the slide speed SS). For example, while repeating the slide operation, the user can intuitively grasp which tone is changed to at what slide speed SS.

[0083] The processor 10 may change the tone color according to another input value (such as the slide amount or the end position of the slide operation) instead of the slide speed SS.

[0084] The arrangement direction of the electrodes 150a to 150d is not limited to the left-right direction. The arrangement direction of the electrodes 150a to 150d may also be the depth direction (a direction perpendicular to the direction in which the keys of the keyboard 14 are arranged). In this case, the user can change the tone by sliding his / her finger from the depth to the front (or from the front to the depth) on the selection switch 15A.

[0085] The settings that can be changed by the selection switch 15A are not limited to tone. The settings that can be changed by the selection switch 15A may also be other settings, such as sound effects to be added to musical sounds (effects such as reverb, wow, and distortion). That is, the processor 10 may switch the type of effect according to the slide speed SS. The processor 10 may also switch both the type of tone and the type of effect according to the slide speed SS. Additionally, the first setting (e.g., the current setting) and the second setting (e.g., the changed setting) may include, for example, at least one of tone and effect settings. The processor 10 may switch another setting instead of or in addition to tone and effect according to the slide speed SS.

[0086] For example, in terms of operability, it is difficult to increase the number of tones that can be changed with one selection switch 15A. Therefore, multiple selection switches 15A may be provided. This increases the number of tones that can be changed with the selection switch 15A.

[0087] When multiple selection switches 15A are provided, the changeable settings may be different for each selection switch 15A. For example, one selection switch 15A may be able to change the tone, and another selection switch 15A may be able to change the vibrato depth.

[0088] In the above embodiment, the tone color is changed in both the normal mode and the standby mode. However, the settings to be changed may be different between the normal mode and the standby mode. For example, the vibrato depth may be changed in the normal mode, and the tone color may be changed in the standby mode. That is, the processor 10 may execute a first process in response to an operation in the standby mode, and execute a second process different from the first process in response to an operation in the normal mode.
