Description

    The present invention relates to a musical sound generating device, and more particularly to a musical sound generating device that generates a sound by switching a plurality of elements.

  2. Description of the Related Art Conventionally, there has been known an apparatus capable of storing a plurality of element data each of which is waveform data or the like as an element set and sequentially generating musical sounds based on the elements included in the element set (see, for example, Patent Document 1).

  In such a device, for example, an element set called “count voice” or “scat” is stored. The “count voice” can be designated and sounded as “ichi, ni, san, ichi, ichi, ni, san, sh ...” by the user operating the performance operator continuously. Also, “Scat” is designated and can be pronounced as “Shu, Bee, Doo, Bah...” When the user operates the performance operator continuously.

JP 2008-191657 A

  For the above-mentioned “count voice”, “ichi” is the start of a series of counts, and for “scat”, “Shu” is the start of a series of scat, so the phrase after the rest is new. It is preferred that the pronunciation of these elements begins at the beginning of the period.

  Since the conventional musical tone generator only generates the elements in the element set sequentially, the above-mentioned “count voice” “ichi” and “scat” “shu” are musical delimiters such as phrase positions. There is a case where the sound is generated regardless of the position, resulting in an unnatural performance.

  Also, when multiple sound generation timings (note-on events) are input consecutively, if the sound generation timings are almost the same but slightly shifted, the sound generation is performed with the same element for the sound generation timings. However, it is preferable that the sound is generated by different elements at each sound generation timing, resulting in an unnatural performance.

  An object of the present invention is to provide a musical sound generating apparatus that enables a natural performance according to a user's intention by switching a plurality of elements.

  According to one aspect of the present invention, a musical sound generating device includes storage means for storing element data for generating musical sounds, a sequence list for recording the sounding order of the plurality of element data, and at least a sounding start instruction. Detection means for detecting instructions related to pronunciation, measuring means for measuring a time interval of the instructions related to pronunciation continuously detected before and after, and in the order of pronunciation recorded in the sequence list according to the detected pronunciation start instruction Selecting means for sequentially selecting one of the element data; control means for controlling the progress of selection of the element data by the selecting means according to the time interval; and reading the selected element data from the storage means. And a musical sound generating means for generating musical sounds.

  According to the present invention, it is possible to provide a musical sound generating apparatus that enables a natural performance by switching a plurality of elements.

  FIG. 2 is a block diagram showing an example of a hardware configuration of the waveform memory sound source 18 according to the embodiment of the present invention.

  The waveform memory sound source 18 includes a waveform memory 81 that stores a plurality of elements (waveform data corresponding to a voice) for one period or more, a plurality of sound generation channels 82, a mixed effect processing unit 83, and a sound source register 84.

  Each tone generation channel 82 includes a waveform reading unit 181, a timbre filter unit 182, a volume control unit 183, an LFO unit 184, and an EG unit 185.

  The tone generator register 84 is a register for controlling the units 181 to 185 and the mixed effect processing unit 83 of the sound generation channel 82.

  The sound source unit is not limited to the waveform memory sound source 18 described here, and any type of sound source can be used as long as a desired element can be generated.

  3A to 3C are time charts showing an example of tone generation according to the first embodiment of the present invention. In the first embodiment of the present invention, the voice data VD that stores at least one sequence list for sequentially generating a series of multiple elements (waveform data) “Shu, Bee, Doo, Bah...” Is selected. Has been.

  FIG. 3A is a diagram for explaining an operation example when the time interval from key-on to next key-on is short. In this example, when the time interval from key-on to the next key-on is less than a predetermined time (30 msec, 50 msec, 70 msec, etc.), the sequence list index IX (FIG. 4) is not advanced.

  First, at the timing t1, the first key-on event occurs, and the element “Shu” is pronounced accordingly. Thereafter, a second key-on event occurs at timing t2 after less than 30 msec from timing t1. At this time, in the conventional example, the index IX of the sequence list is advanced, and “Bee” is pronounced. However, if different elements are pronounced at a time interval of less than 30 msec, an unnatural impression is given musically. Therefore, in this embodiment, when the time interval between two key-on events is less than a predetermined value (30 msec in this embodiment), the index IX of the sequence list is not advanced, and the two key-on events are changed. On the other hand, the same element is pronounced.

  Therefore, as shown in FIG. 3A, the element “Shu” is sounded at both timings t1 and t2. At timing t3, since 30 msec or more has elapsed from timing t2, the index IX of the sequence list is advanced first, and the element “Bee” is sounded. Further, at timing t4, 30 msec or more has elapsed from timing t2, and since two key-on events have occurred at the same time, the same element “Doo” is sounded for the two key-on events.

  FIG. 3B is a diagram for explaining an operation example when the time interval from key-off to next key-on is long. In this example, when the time interval from key-on to the next key-on is a predetermined time (300 msec, 350 msec, 400 msec, etc.) or more, the sequence list index IX (FIG. 4) is reset (returned to the top of the list). Yes.

  A key-off event corresponding to the elements “Shu” and “Bee” occurs at timing t5, and a key-on event occurs at timing t6 after elapse of a predetermined time (350 msec in this embodiment). In this case, in the conventional example, the index IX of the sequence list is advanced, and the element “Doo” is pronounced. However, if there is an interval of a certain time or more, if it is pronounced from the continuation of the sequence, it is musically It becomes unnatural. Therefore, in this embodiment, when the time interval from the key-off event corresponding to the immediately preceding element to the next key-on event is equal to or longer than a predetermined time (for example, 350 msec), the index IX of the sequence list is temporarily reset, Return to the beginning.

  Therefore, in this example, the element “Shu” which is the head of the sequence list is sounded in response to the key-on event at timing t6, and thereafter, the elements of the sequence list are sounded sequentially.

  FIG. 3C is a diagram for explaining an operation example in the case of switching an element to be sounded by operating a predetermined setting operator 12 such as a rendition style switch. In this example, in the rendition style switch ON state (sound generation condition 1), the sound generation (selection) element is switched to a specific element (special sound generation element 1 in FIG. 4), and a specific note number or velocity value is selected in the rendition style switch ON state. When a note-on event having (sounding condition 2) occurs, the sounding (selection) element is switched to a specific element (special sounding element 2 in FIG. 4).

  First, after the elements “Shu, Bee, Doo” are sequentially sounded, the rendition style switch (setting operator) 12 is operated at timing t7, and the rendition style switch ON state (the rendition style switch state variable in FIG. 4 is changed to “TRUE”). Is set). Thereafter, when a note-on event that is not a specific note number or velocity value (sounding condition 2) occurs at an arbitrary timing, the element “Daa” defined as the special sounding element 1 is sounded. At timing t8, a note-on event having a specific note number or velocity value (sounding condition 2) occurs, and the element “Hey!” Defined as the special sounding element 2 is sounded. Thereafter, when the rendition style switch (setting operator) 12 is operated at timing t9, the rendition style switch is turned off (the rendition style switch state variable in FIG. 4 is set to “FALSE”). Thereafter, when a no-on event occurs, the normal sequence list is sounded. In this case, the first element “Shu” is first pronounced.

  That is, for the occurrence of a no-on event in a state where neither the sounding condition 1 (the rendition style switch is on) or the sounding condition 2 (the occurrence of a note-on event having a specific note number or velocity value) is satisfied, In response to the occurrence of a no-on event in the state where only the sounding condition 1 is satisfied, the special sounding element 1 is sounded and both the sounding condition 1 and the sounding condition 2 are satisfied. In response to the occurrence of a no-on event, the special sounding element 2 is sounded. In addition, when a transition is made from a state satisfying the sound generation condition 1 to a state not satisfying, the normal sequence list index IX is reset.

  FIG. 4 is a conceptual diagram showing an example of the configuration of pronunciation management data and voice data according to the first embodiment of the present invention.

  The pronunciation management data MD is stored, for example, in a predetermined area in the RAM 7 of FIG. 1, and reference information VL to the voice data, the last note-on time OT, the last note-off time FT, the rendition style switch state variable SV, It includes an index IX of the sequence list and a note list NL during pronunciation.

  The reference information VL to the voice data of the pronunciation management data MD holds reference information to the selected voice data (selected voice data) VD among the voice data group stored in the ROM 8 or the like. Each time the user reselects a voice, the reference information VL to this voice data is updated. When processing the note-on event, the voice data VD is traced from the reference information VL to the voice data, information on the element to be sounded is obtained, and the sound source 18 is set.

  The last note-on time OT holds the time when the note-on event is processed. The last note-on time OT is updated every time a note-on event is processed. This data is used to select an element when processing subsequent note-on events.

  The last note-off time FT holds the time when the note-off event is processed. The last note-off time FT is updated every time a note-off event is processed. This data is used to select an element when processing subsequent note-on events.

  The rendition style switch state variable SV holds the ON / OFF state of the rendition style switch (setting operation element) 12. The state is switched to “TRUE” by processing the rendition style switch-on event, and the state is switched to “FALSE” by processing the rendition style switch-off event.

  The index IX of the sequence list is an index for sequentially selecting the element information stored in the sequence list SL in the voice data VD one by one in the recording order, and is advanced by one every time a Norton event occurs in principle. .

  The sounding note list NL manages note information NI corresponding to the note (musical sound) currently being sounded by the sound source 18 as a list. The note information NI which is each entry in the sounding note list NL represents a note (musical tone) being sounded, and includes a note number NN, a release state flag RF, and sounding channel management information CM.

  In the processing of the note-on event, a sound generation channel 82 (a sound source resource unit necessary for reproducing and generating one waveform data) is secured, and the note number NN of the note-on event and the management information of the secured sound generation channel 82 are secured. The release status flag RF having the value of CM and “FALSE” is added to the sounding note list NL as one entry.

  In the processing of the note-off event, a corresponding entry is searched from the sounding note list NL based on the note number of the note-off event, the release state flag RF of the entry is set to “TRUE”, and the sounding channel 82 is changed to the sound channel after the note-off. Instruct them to pronounce during the release. At this time, the entry is not yet deleted from the sounding note list NL. The entry is deleted by, for example, monitoring an entry being released in a periodic process (an entry whose release state flag RF is “TRUE”), obtaining the volume level of the sound channel 82 being released from the sound source, and keeping the volume constant. When the value falls below the value, the corresponding entry is deleted.

  The voice data group includes a plurality of voice data VD and is stored in, for example, the ROM 8 or the storage device 15 in FIG. Each voice data VD includes a voice name VN, mode information MI, a sequence list SL, and a special tone generation element SE. In the figure, one voice data is selected. The voice data VD is a set of parameters for each voice that can be generated by the musical tone generation apparatus 100. Many voice data VD are recorded in the ROM 8 as presets. Alternatively, a large number of voice data VD is recorded in the storage device 15 such as a non-volatile memory, which is created by a user or acquired from various media.

  The voice name VN is a character string for the user to identify each voice such as “ScatVoice” and “AcousticPiano1”. In addition to the voice name VN, an identifier (identification number or the like) for identifying the voice data such as a program change number may be recorded.

  The mode information MI is recorded in the sound generation mode. The sound generation mode indicates whether it is a voice for reading a normal waveform from the past, or a voice for “cycle sound generation” according to the present embodiment.

  The sequence list SL is a list in which a plurality of elements used in “cycle pronunciation” are recorded in the order in which they are to be generated, and element information EL corresponding to each element is listed in the order of pronunciation. As a general rule, each time a note is turned on, the elements are cyclically switched and sounded in the order of recording. That is, each time a note is turned on from the top of the list, one element is sounded, and the next recorded element is sounded sequentially. For example, when four elements are recorded: element 1 “Shu”, element 2 “Bee”, element 3 “Doo”, element 4 “Bah”, “Shu, Bee, Doo, Bah, Shu, Bee... Can be pronounced.

  Each element information EL includes, for example, reference information to waveform data and a voice parameter. The reference information to the waveform data is information for the waveform reading unit 181 to read the waveform data recorded in the waveform memory 81 of FIG. 2, for example, the address of the waveform memory 81 viewed from the waveform reading unit 181. . The voice parameter is a parameter value set in the timbre filter unit 182, the LFO unit 184, or the EG unit 185.

  The special sounding element SE is information for sounding an element different from the element recorded in the sequence list SL when a specific sounding condition is met. In the example shown in the figure, the sound generation condition PN1 as a condition for switching from the sequence list SL to the special sound generation element (element 1) to the special sound generation element SE, and the element 1 sounded when the sound generation condition PN1 is satisfied. Element information EL1, the sound generation condition PN2 as an additional condition for switching from element 1 to element 2, and the element information EL2 of element 2 sounded when the sound generation condition PN2 is satisfied are used as the special sound generation element SE. It is recorded. Note that the sound generation conditions PN1 and PN2 may be recorded not in the special sound generation element SE but in the sequence list SL or other places of the voice data VD.

  In the present embodiment, “the rendition style switch is ON (state where the rendition style switch state variable in FIG. 4 is set to“ TRUE ”)” is recorded as the sound generation condition PN1, and the sound is generated when the sound generation condition PN1 is satisfied. Element information EL1 associated therewith is recorded. In addition, “specific note number (for example, note number“ 127 ”) and / or specific velocity value” is recorded as sounding condition 2, and element information that is sounded when sounding condition PN1 and sounding condition PN2 are satisfied. EL2 is recorded in association with the sound generation condition PN2.

  FIG. 5 is a flowchart showing main processing according to the first embodiment of the present invention. This main process is executed immediately after the tone generator 100 is turned on. The same applies to the second to fourth embodiments described later except for the note-on process in step SA6.

  In step SA1, main processing is started, and in step SA2, initial setting is performed. Here, the states of various parameters on the RAM 7 (FIG. 1) are set to initial values.

  In step SA3, the voice is switched (selected) according to the user's operation. A voice selection operation using the setting operator 12 (FIG. 1) of the user is detected, and voice data VD is selected from the voice data group (FIG. 4) according to the voice selection operation.

  By the selection process of the voice data VD, the sound generation management data MD (FIG. 4) on the RAM 7 for managing sound generation is initialized. That is, referring to the sounding note list NL, if there is a sounding note, the sound is muted (for example, the release state flag RF is set to “TRUE”). Thereafter, when the volume level of the sound generation channel 82 that is sounding the note becomes a certain value or less, the information corresponding to the note is deleted from the sounding note list NL so that there is no sound that is being sounded. Next, the reference information VL to the voice data is rewritten to the reference information of the voice data VD selected in step SA3. Thereafter, the last note-on time OT and the last note-off time FT are cleared, and the index IX of the sequence list is set to the first element information EL of the sequence list SL.

  In step SA4, the occurrence of an event due to a performance operation using the performance operator 22 (FIG. 1) of the user (including a case where a MIDI event is received via the communication I / F 21) is detected. Thereafter, in step SA5, distribution processing is performed according to the event detected in step SA4. If the event detected in step SA4 is a note-on event, the process proceeds to step SA6 indicated by an arrow A. If the event is a note-off event, the process proceeds to step SA7 indicated by an arrow B, and if the rendition style switch is on. The process proceeds to step SA8 indicated by the arrow C, and if the rendition style switch is OFF, the process proceeds to step SA9 indicated by the arrow D and if the above event is not detected (if any other event is detected or no event is detected) If not detected), the process proceeds to step SA10 indicated by an arrow E.

  In step SA6, note-on event processing shown in FIG. 6 is performed. For example, when the user presses a key on the keyboard (performance operator 22), the detection circuit 11 (FIG. 1) detects it and introduces a note-on event to the CPU 9. The CPU 9 executes the note-on event process shown in FIG. 6 accordingly. Note that the note-on event includes a note number and velocity. Thereafter, the process returns to step SA3.

  In step SA7, note-off event processing shown in FIG. 7 is performed. For example, when the user performs a key release operation on the keyboard (the performance operator 22), the detection circuit 11 (FIG. 1) detects it and introduces a note-off event into the CPU 9. The CPU 9 executes the note-off event process shown in FIG. 7 accordingly. Note that the note-on event includes at least a note number. Thereafter, the process returns to step SA3.

  In step SA8, the rendition style switch state variable SV of the pronunciation management data MD in the RAM 7 shown in FIG. 4 is set to “TRUE”. For example, when the user turns on a performance style switch (setting operation element 12), a performance style switch-on event is introduced to the CPU 9, and the CPU 9 sets the performance style switch state variable SV of the pronunciation management data MD in the RAM 7 to “TRUE”. Thereafter, the process returns to step SA3.

  In step SA9, the rendition style switch state variable SV of the pronunciation management data MD in the RAM 7 shown in FIG. 4 is set to “FALSE”. For example, when the user turns off the rendition style switch (setting operation element 12), a rendition style switch off event is introduced to the CPU 9, and the CPU 9 sets the rendition style switch state variable SV of the pronunciation management data MD in the RAM 7 to "FALSE". Thereafter, the process returns to step SA3.

  In step SA10, sound channel monitoring processing is executed. In the sound channel monitoring process, as described above with reference to FIG. 4, the entry is deleted from the sounding note list NL. For example, an entry whose release state flag RF is “TRUE” is searched from the sounding note list NL, the sounding channel management information CM of the detected entry is referred to, the sounding channel 82 is specified, and the volume of the specified sounding channel 82 is determined. A value (or an EG value that controls the volume) is acquired. When the acquired volume value or the like is smaller than a predetermined value (a volume that is almost inaudible), the entry is deleted from the sounding note list NL. Thereafter, the specified sound generation channel can be used for sound generation of other musical sounds.

  In step SA11, other processing is performed. Here, various processes are executed according to the user's operation. For example, real-time modulation processing of a musical tone being generated, automatic performance setting processing, and execution processing thereof. Thereafter, the process returns to step SA3.

  In addition, when returning to step SA3 after the process of step SA6-step SA9 and step SA11, it is preferable to leave a predetermined time interval using the timer 10.

  FIG. 6 is a flowchart showing the note-on process executed in step SA6 of FIG. 5 in the first embodiment of the present invention.

  In step SB1, note-on processing is started. In step SB2, the current time is acquired from the timer 10 (FIG. 1), and the last note-on in the pronunciation management data MD in FIG. 4 recorded in the RAM 7 in FIG. The time OT is updated with the acquired current time.

  In step SB2, a note number and a velocity value are extracted from the note-on event detected in step SA4 in FIG.

  In step SB4, the mode information MI of the voice data VD selected in step SA3 in FIG. 5 is referred to, and it is determined whether or not the voice should be the cycle sound “WaveCycle”. If it is a voice to be cycled, the process proceeds to step SB6 indicated by an arrow of YES, and if it is not a voice to be cycled, the process proceeds to step SB5 indicated by an arrow of NO.

  In step SB5, an element corresponding to another sound generation mode (normal sound generation other than cycle sound generation) is selected, and the process proceeds to step SB18.

  In step SB6, it is determined whether or not the sound generation condition 1 is satisfied. Note that the sounding condition 1 is, for example, the sounding condition PN1 defined by the special sounding element SE of FIG. 4, and in the first embodiment, “the rendition style switch is ON (the rendition style switch state variable SV of FIG. 4). "Is set to" TRUE ")" is set as the sound generation condition 1. When the sound generation condition 1 is satisfied, that is, when the rendition style switch is in the ON state, the process proceeds to step SB7 indicated by a YES arrow. When the sound generation condition 1 is not satisfied, that is, when the rendition style switch is in the OFF state, the process proceeds to Step SB10 indicated by a NO arrow.

  In step SB7, it is determined whether or not the sound generation condition 2 is satisfied. The sounding condition 2 is, for example, the sounding condition PN2 defined by the special sounding element SE of FIG. 4, and in the first embodiment, “specific note number (for example, note number“ 127 ”)”. It is assumed that “and / or a specific velocity value” is set as the sound generation condition 2. When the sound generation condition 2 is satisfied, that is, when both the sound generation conditions 1 and 2 are satisfied, the process proceeds to step SB8 indicated by a YES arrow. If the sound generation condition 2 is not satisfied, that is, if only the sound generation condition 1 is satisfied, the process proceeds to step SB9 indicated by a NO arrow.

  In step SB8, the special tone generation element 2 is selected. Specifically, the waveform data referred to by the special element information EL2 in the special sounding element SE of FIG. 4 is selected. Thereafter, the process proceeds to step SB18.

  In step SB9, the special tone generation element 1 is selected. Specifically, the waveform data referred to by the special element information EL1 in the special sounding element SE of FIG. 4 is selected. Thereafter, the process proceeds to step SB18.

  As a result of the processing from step SB6 to step SB9 described above, a note-on event having a specific velocity value or volume value is generated when the rendition style switch is ON (sounding condition 1 is satisfied) (sounding condition 2 is satisfied). ) And the special sounding element 2 are selected, and only the sounding condition 1 is satisfied, the special sounding element 1 can be selected.

  In step SB10, it is determined whether or not the performance style switch state variable has transitioned from “TRUE” to “FALSE”. If the rendition style switch state variable transitions from “TRUE” to “FALSE”, the process proceeds to step SB11 indicated by an arrow “YES” to reset the index IX of the sequence list of the pronunciation management data MD in FIG. 4 (return the index to the top). ), Go to Step SB12. In other cases, as indicated by the NO arrow, step SB11 is skipped and the process proceeds to step SB12. When the rendition style switch is turned off from the rendition style switch ON state and the special sounding element temporarily selected returns to the normal sequence list, the index is reset by this processing, and the normal sequence element is played from the beginning. It is possible to resume. Note that the processing in step SB10 may be the same as step SB401 (FIG. 16) in the fourth embodiment described later, and it may be determined whether or not the reset condition RC is satisfied. In that case, the reset condition RC is recorded in the voice data VD of FIG.

  In step SB12, whether or not the time from the last note-off time FT in the pronunciation management data MD in FIG. 4 recorded in the RAM 7 in FIG. 1 to the current time acquired in step SB2 is a predetermined time (for example, 350 msec) or more. Judging. When the time is equal to or longer than the predetermined time, the process proceeds to Step SB13 indicated by a YES arrow, and when the time is less than the predetermined time, the process proceeds to Step SB15 indicated by a NO arrow.

  In step SB13, it is determined whether or not all the release state flags RF of the note information NI recorded in the sounding note list NL in the sound management data MD of FIG. 4 are “TRUE”. When all are “TRUE”, the process proceeds to Step SB14 indicated by an arrow of YES. If there is even one “FALSE”, it is determined that there is a musical tone being generated, and the process proceeds to step SB15 indicated by a NO arrow. If the note information NI is not recorded in the sounding note list NL, there is no musical sound being sounded, so the process proceeds to step SB14 indicated by the YES arrow.

  In step SB14, the index IX of the sequence list of the pronunciation management data MD in FIG. 4 is reset (the index is returned to the top), and then the process proceeds to step SB17.

  Through the processes in steps SB12 to SB14 described above, when a Norton event occurs after a predetermined time has elapsed since the last note-off time, the sequence index can be reset and a plurality of elements can be sounded again from the beginning.

  In step SB15, is the time from the last note-on time OT in the pronunciation management data MD of FIG. 4 recorded in the RAM 7 of FIG. 1 to the current time acquired in step SB2 less than a predetermined time (for example, 30 msec or 70 msec)? Judge whether or not. If it is less than the predetermined time, the process proceeds to step SB17 indicated by an arrow of YES, and if it is longer than the predetermined time, the process proceeds to step SB16 indicated by an arrow of NO.

  In step SB16, the index IX of the sequence list of the pronunciation management data MD in FIG. 4 is advanced by one, and thereafter, the process proceeds to step SB17. When the index IX indicates the last element information EL of the sequence list SL, the index is returned to the top.

  By the above steps SB15 to SB16, when a note-on event occurs before a certain time has elapsed since the last note-on time, the same element can be re-sound without proceeding with the sequence index. it can.

  In step SB17, the element (element information EL) indicated by the index IX of the sequence list of the pronunciation management data MD in FIG. 4 is selected. Thereafter, the process proceeds to step SB18.

  In step SB18, a usable sound generation channel 82 is secured, and the sound source 18 is instructed to cause the sound generation channel 82 to sound the element selected in step SB8, SB9 or step SB17. Specifically, the sound generation channel 82 that is not currently used in the sound source 18 is selected, the reference information to the waveform data to be sounded is read from the voice data VD, and written into the sound source register 84 to instruct sound generation.

  In step SB19, the information (entry) of the tone (note) for which the sound generation instruction is given in step SB18 is added to the tail of the sounding note list NL in the sound management data MD of FIG. Specifically, the note number NN of the note-on event detected in step SA4 in FIG. 5, the management information CM of the sound channel 82 secured in step SB18 (including information specifying the sound channel 82), and the value of “FALSE” The release state flags RF are collectively added as one entry to the sounding note list NL.

  In step SB20, the last note-on time OT in the pronunciation management data MD of FIG. 4 recorded in the RAM 7 of FIG. 1 is updated with the current time acquired in step SB2. Thereafter, the process proceeds to step SB21, where the note-on process is terminated and the process returns to step SA3 in FIG.

  FIG. 7 is a flowchart showing the note-off process executed in step SA7 of FIG. This note-off process is a process common to the embodiments of the present invention.

  In step SC1, note-off processing is started. In step SC2, the current time is acquired from the timer 10 (FIG. 1), and the last note in the pronunciation management data MD in FIG. 4 recorded in the RAM 7 in FIG. The off time FT is updated with the acquired current time.

  In step SC3, a note number is extracted from the note-off event detected in step SA4 in FIG.

  In step SC4, an entry (note information NI) containing the same note number NN as the note number extracted in step SC3 from the sounding note list NI in the sound management data MD of FIG. 4 recorded in the RAM 7 of FIG. )

  In step SC5, the release state flag RF of all entries (note information NI) detected in step SC4 is set to “TRUE”.

  In step SC6, the sound source 18 is instructed to release the sounding notes (musical sounds) of all the entries (note information NI) detected in step SC4. Thereafter, the process proceeds to step SC7, the note-off process is terminated, and the process returns to step SA3 in FIG. The release instruction to the sound source 18 here specifies, for example, the sound generation channel 82 of the sound source 18 that is sounding the musical sound corresponding to the note information NI from the sound generation channel management information CM of the detected note information NI. The setting is written in the tone generator register 84 so that the tone generation channel 82 generates a musical tone while releasing it. During the release, envelope data is supplied from the EG unit 185 to the volume control unit 183 so as to gradually attenuate.

  As described above, according to the first embodiment of the present invention, when the interval from a key-on event to the next key-on event is less than a predetermined time, sound generation is performed using the same element (waveform data) for both key-on events. And the sequence of elements cannot be advanced.

  Further, when the interval from the key-off event to the next key-off event is equal to or longer than a certain time, the element sequence can be reset and the sound generation can be resumed from the first element.

  Furthermore, for a key-on event in a state where a certain sound generation condition is satisfied, sound generation can be performed using an element different from an element used in a normal sequence. Thereby, the user can temporarily switch a desired element at a desired timing.

  In the first embodiment of the present invention, in the note-on process shown in FIG. 6, the last note-on time OT is updated at step SB20 every time a note-on event occurs. When it is determined at SB15 that the time is less than the predetermined time, the last note-on time OT is not updated at step SB20, and only when it is determined that the time is longer than the predetermined time, the last note-on time at step SB20. The OT may be updated. In this case, in the example shown in FIG. 3A, when “Shu” is pronounced at time t1, the last note-on time OT is time t1, but when “Shu” is pronounced at time t2, The last note-on time OT is not updated at time t2 and remains at time t1. Then, the element that sounds at time t3 does not sound “Bee” next to “Shu” when the elapsed time from time t2 is equal to or longer than the predetermined time, but the elapsed time from time t1 is the predetermined time. In this case, “Bee” next to “Shu” is pronounced.

  Next, a second embodiment of the present invention will be described. In the second embodiment, voice data including a plurality of sequence lists is selected, and the sequence lists are switched according to sound generation conditions. In the second embodiment, the hardware configuration shown in FIGS. 1 and 2 is the same as that in the first embodiment, and the main processing shown in FIG. 5 and the note-off processing shown in FIG. 7 are also in the first embodiment. It is the same. Only the parts different from the first embodiment will be described below.

  FIGS. 8A and 8B are time charts showing an example of tone generation according to the second embodiment of the present invention. In the second embodiment of the present invention, a sequence list for performing a series of pronunciations “Doo, Bee, Doo...” And a series of pronunciations “Shu, Bee, Dah, Bah. Voice data VD having a sequence list is selected.

  FIG. 8A shows an example of switching to the second sequence in the middle of the first sequence by the rendition style switch ON operation (sounding condition).

  After the first sequence “Doo, Bee, Doo...” Is pronounced “Doo”, “Bee”, “Doo”, the rendition style switch is turned on at timing t10. Thereafter, the sequence is switched to the second sequence, and “Shu”, “Bee”, “Dah”, and “Bah” are pronounced. Although illustration is omitted, the sequence returns to the first sequence when the rendition style switch OFF operation is performed. That is, in this example, the element of the first sequence is selected in the rendition style switch OFF state, and the element of the second sequence is selected in the rendition style switch ON state.

  FIG. 8B shows an example of switching between the first sequence and the second sequence according to the note-on event range (sound generation condition).

  In this example, if the note number of the note-on event is greater than or equal to a predetermined value (high range), the first sequence element is selected, and if it is less than the predetermined value (low range), the second sequence element is selected. Selected.

  FIG. 9 is a conceptual diagram showing an example of the configuration of pronunciation management data and voice data according to the second embodiment of the present invention.

  In the second embodiment, the index IX of the sequence list of the pronunciation management data MD in the first embodiment is two independent systems of the index IX1 and IX2 of the sequence list. Other configurations are the same as those of the first embodiment. Also, the index IX1 and IX2 of the sequence list have the same configuration as the index IX of the sequence list in the first embodiment.

  In the voice data VD, sequence lists SL1 and SL2 are prepared corresponding to the index IX1 and IX2 of the sequence list, respectively, and the special tone generation element SE is omitted. Other configurations are the same as those of the first embodiment. The configuration of the sequence list SL1 is the same as that of the sequence list SL according to the first embodiment. In the sequence list SL2, a sound generation condition PN that is a condition for switching from the sequence list SL1 to SL2 is recorded. When switching in the rendition style switch ON state, that effect is recorded in this tone generation condition, and when switching in the tone range, a note number serving as a switching point is recorded. The sound generation condition PN may be recorded in SL1 instead of the sequence list SL2. Also, the tone generation condition PN in the second embodiment is not limited to “playing style switch ON” or “note number greater than a predetermined value”, but may be “velocity greater than a predetermined value” or the like. In the case of a note number or a velocity value, “note number within a predetermined range” or “velocity value within a predetermined range” may be used as the sound generation condition PN.

  In the second embodiment, the voice data VD records two independent sequence lists SL1 and SL2, and the pronunciation management data MD also holds two indexes IX1 and IX2 corresponding thereto. Thus, the two sequences can be switched according to the sound generation conditions.

  FIG. 10 is a flowchart showing the note-on process executed in step SA6 of FIG. 5 in the second embodiment of the present invention.

  The second embodiment can be realized by replacing steps SB6 to SB17 with steps SB201 to SB208 described later in the note-on processing shown in FIG. 6 of the first embodiment. In addition, since the process of step SB1-SB3 and SB18-SB21 is the same as that of a 1st Example, illustration and its description are abbreviate | omitted.

  In step SB4, the mode information MI of the voice data VD selected in step SA3 in FIG. 5 is referred to, and it is determined whether or not the voice should be the cycle sound “WaveCycle”. If it is a voice to be cycled, the process proceeds to step SB201 indicated by a YES arrow, and if it is not a voice to be cycled, the process proceeds to step SB5 indicated by a NO arrow. In step SB5, an element corresponding to another sound generation mode (such as normal sound generation other than cycle sound generation) is selected, and the process proceeds to step SB18.

  In step SB201, it is determined whether the state where the sounding condition PN in FIG. 9 is satisfied is changed to a state where the sounding condition PN is not satisfied, or the state where the sounding condition PN is not satisfied in FIG. to decide. When the state transitions from the state satisfying the sound generation condition PN to the state not satisfied, the process proceeds to step SB202 indicated by the arrow A, and conversely, when the state transitions from the state not satisfied to the state satisfied, the process proceeds to step SB203 indicated by the arrow B. When the tone generation condition PN in FIG. 9 is “performance style switch ON”, “from the performance style switch is ON (the performance style switch state variable SV in FIG. 9 is set to“ TRUE ”)” to “the performance style switch is OFF ( It is determined whether or not the performance style switch state variable SV in FIG. 9 has transitioned to “a state in which the performance style switch SV is set to“ FALSE ”” or vice versa. This is determined, for example, by detecting a rendition style switch ON or OFF operation. When the sound generation condition PN in FIG. 9 is “note number greater than or equal to a predetermined value”, the note number extracted in step SB2 in FIG. 6 has transitioned from less than a predetermined value to a predetermined value or more, or from a predetermined value to less than a predetermined value. It is determined whether or not Further, the case where the sound generation condition PN of FIG.

  In step SB202, the index IX1 of the sequence list of the pronunciation management data MD in FIG. 9 is reset (the index is returned to the top). Thereafter, the process proceeds to step SB204.

  In step SB203, the index IX2 of the sequence list of the pronunciation management data MD in FIG. 9 is reset (the index is returned to the top). Thereafter, the process proceeds to step SB204.

  Note that steps SB201 to SB203 are not essential processing and may be omitted. In that case, when the sequence list is switched and then returned to the original sequence list, the sound is generated from the continuation of the previous sequence. In the example shown in FIG. 8B, the processing of steps SB201 to SB203 is omitted, and even if a low frequency performance is performed after a high frequency performance and a high frequency performance is performed again, the index of the sequence list is not changed. Not reset. If the processing of steps SB201 to SB203 is omitted, the index of the sequence list of the pronunciation management data MD in FIG. 9 is required to be two of IX1 and IX2, but if not omitted, every time the sequence list is switched. Since it is reset, only one index may be used as in the first embodiment.

  Step SB204 determines whether or not the sound generation condition PN of FIG. 9 is satisfied. If the sound generation condition PN is satisfied, the process proceeds to step SB205 indicated by an arrow of YES, and the index IX1 of the sequence list of the sound generation management data MD in FIG. 9 is advanced by 1, and then the process proceeds to step SB206. When the index IX1 indicates the last element information EL of the sequence list SL1, the index is returned to the top. If the sound generation condition PN is not satisfied, the process proceeds to step SB207 indicated by an arrow of NO, the index IX2 of the sequence list of the sound generation management data MD in FIG. 9 is advanced by 1, and then the process proceeds to step SB208. When the index IX2 indicates the last element information EL of the sequence list SL1, the index is returned to the top.

  In the process of step SB204, if the tone generation condition PN in FIG. 9 is “performance style switch ON”, is the “performance style switch ON (state in which the performance style switch state variable SV in FIG. 9 is set to“ TRUE ”)”? Judge whether or not. If the sound generation condition PN in FIG. 9 is “note number greater than or equal to a predetermined value”, it is determined whether or not the note number extracted in step SB2 in FIG. 6 is greater than or equal to a predetermined value. In addition, when the sound generation condition PN in FIG. 9 is “velocity greater than or equal to a predetermined value”, whether the velocity value extracted in step SB2 in FIG. Judge whether or not.

  In step SB206, the element (element information EL) indicated by the index IX1 in the sequence list of the pronunciation management data MD in FIG. 9 is selected. Thereafter, the process proceeds to step SB18 in FIG.

  In step SB208, the element (element information EL) indicated by the index IX2 of the sequence list of the pronunciation management data MD in FIG. 9 is selected. Thereafter, the process proceeds to step SB18 in FIG.

  As described above, according to the second embodiment of the present invention, two sequences can be switched in accordance with the sound generation conditions.

  Next, a third embodiment of the present invention will be described. In the third embodiment, sound generation according to a normal sequence list and sound generation by a single element are switched according to sound generation conditions. In the third embodiment, the hardware configuration shown in FIGS. 1 and 2 is the same as that in the first embodiment, and the main process shown in FIG. 5 and the note-off process shown in FIG. 7 are also in the first embodiment. It is the same. Only the parts different from the first embodiment will be described below.

  FIG. 11 is a time chart showing an example of tone generation according to the third embodiment of the present invention. This shows an example of switching between sound generation according to a normal sequence list and sound generation by a single element, depending on the note-on event sound range (sound generation condition).

  In this example, if the note number of the note-on event is greater than or equal to a predetermined value (high range), the normal sequence elements “Shu”, “Bee”, “Doo”, and “Bah” are sequentially selected and less than the predetermined value. If it is (low range), the single element “Boom” is always selected.

  FIG. 12 is a conceptual diagram showing an example of the configuration of pronunciation management data and voice data according to the third embodiment of the present invention.

  The pronunciation management data MD is the same as in the first embodiment. In the voice data VD, element designation information EA that designates a single element selected when the tone generation condition PN is satisfied is recorded instead of the special tone generation element SE. The sequence list SL records a sound generation condition PN that is a condition for switching from the sequence list SL to a single element. In the present embodiment, since switching is performed according to the sound range, a note number serving as a switching point is recorded in the sound generation condition PN (in this embodiment, the sound generation condition is “note number less than a predetermined value”). . The sound generation condition PN may be recorded not in the sequence list SL but in the element designation information EA. Other configurations are the same as those of the first embodiment. Note that the tone generation condition PN in the second embodiment is not limited to “note numbers less than a predetermined value”, but “note numbers greater than a predetermined value”, “playing style switch ON”, and “velocities greater than (or less than) a predetermined value”. Or the like. Further, “note number within a predetermined range” and “velocity value within a predetermined range” may be used as the sound generation condition PN.

  In the third embodiment, the voice data VD records a sequence list SL and element designation information EA that designates a single element. This makes it possible to switch between normal sequence sound generation and sound generation using only a single element according to the sound generation conditions.

  FIG. 13 is a flowchart showing the note-on process executed in step SA6 of FIG. 5 in the third embodiment of the present invention.

  The third embodiment can be realized by replacing steps SB6 to SB17 with steps SB301 to SB306 described later in the note-on processing shown in FIG. 6 of the first embodiment. In addition, since the process of step SB1-SB3 and SB18-SB21 is the same as that of a 1st Example, illustration and its description are abbreviate | omitted.

  In step SB4, the mode information MI of the voice data VD selected in step SA3 in FIG. 5 is referred to, and it is determined whether or not the voice should be the cycle sound “WaveCycle”. If it is a voice to be sounded in a cycle, the process proceeds to step SB301 indicated by an arrow of YES, and if it is not a voice to be sounded in a cycle, the process proceeds to step SB5 indicated by an arrow of NO. In step SB5, an element corresponding to another sound generation mode (such as normal sound generation other than cycle sound generation) is selected, and the process proceeds to step SB18.

  In step SB301, it is determined whether a reset condition is satisfied. If the reset condition is satisfied, the process proceeds to step SB302 indicated by a YES arrow to reset the index IX of the sequence list of the pronunciation management data MD in FIG. When the reset condition is not satisfied, step SB302 is skipped and the process proceeds to step SB303 as indicated by an arrow “NO”. The reset condition in the present embodiment is “transition from a state not satisfying the sound generation condition PN to a state satisfying”. Alternatively, the “performance switch ON” can be set as a reset condition. Note that the processing in steps SB301 and SB302 can be omitted. In the example shown in FIG. 11, the processes of steps SB301 and SB302 are omitted.

  In step SB303, it is determined whether or not the sound generation condition PN in FIG. 12 is satisfied. If the sound generation condition PN is satisfied, the process proceeds to step SB304 indicated by the YES arrow. When the sound generation condition PN is not satisfied, the process proceeds to step SB305 indicated by an arrow of NO, the index IX of the sequence list of the sound generation management data MD in FIG. 12 is advanced by 1, and then the process proceeds to step SB306. When the index IX indicates the last element information EL of the sequence list SL, the index is returned to the top.

  In the process of step SB303, if the sound generation condition PN in FIG. 9 is “note number less than (or greater than) a predetermined value”, whether or not the note number extracted in step SB2 in FIG. 6 is less than (or greater than) the predetermined value. Determine whether. In addition, when the sound generation condition PN in FIG. 9 is “velocity greater than (or less than) a predetermined value”, the velocity value extracted in step SB2 in FIG. It is determined whether or not it is greater than (or less than) a predetermined value. Further, when the sound generation condition PN in FIG. 9 is “performance style switch ON”, it is determined whether or not “the performance style switch is ON (state in which the performance style switch state variable SV in FIG. 9 is set to“ TRUE ”)”. To do.

  In step SB304, a single element (element information EL) in the element designation information EA in FIG. 12 is selected. Thereafter, the process proceeds to step SB18 in FIG.

  In step SB306, the element (element information EL) indicated by the index IX of the sequence list of the pronunciation management data MD in FIG. 12 is selected. Thereafter, the process proceeds to step SB18 in FIG.

  As described above, according to the third embodiment of the present invention, it is possible to switch between sound generation by a normal sequence and sound generation using only a single element according to sound generation conditions.

  Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, the sequence list index is reset (returned to the top) when the reset condition is satisfied. In the fourth embodiment, the hardware configuration shown in FIGS. 1 and 2 is the same as that in the first embodiment, and the main process shown in FIG. 5 and the note-off process shown in FIG. 7 are also in the first embodiment. It is the same. Only the parts different from the first embodiment will be described below.

  FIG. 14 is a time chart showing an example of tone generation according to the fourth embodiment of the present invention. When the reset condition (in this example, detection of a rendition style switch operation (ON or OFF operation)) is satisfied, the sequence index is reset regardless of the note-on time and the note-off time.

  FIG. 15 is a conceptual diagram showing an example of the configuration of pronunciation management data and voice data according to the fourth embodiment of the present invention.

  The pronunciation management data MD is the same as in the first embodiment. In the voice data VD, the special sound generation element SE is omitted, and a reset condition RC is added to the sequence list SL. The reset condition RC includes a transition from the ON state to the OFF state of the rendition style switch (detection of the OFF operation), and the reverse transition (detection of the ON operation), detection of the operation of other specific operation elements, and the like. Other configurations are the same as those of the first embodiment.

  In the present embodiment, the “playing style switch operation” is set as the reset condition RC. However, the reset condition RC is not limited to this. For example, only the “playing style switch ON operation” or only the “playing style switch OFF operation” Note number (or velocity value) greater than or equal to a predetermined value (or less than or within a predetermined range) ”, operation of a predetermined operator (setting operator 12 or performance operator 22), and the like. That is, in the fourth embodiment, the sequence can be reset at a desired timing according to the user's instruction. Therefore, the reset condition RC may be any as long as the user can instruct the sequence reset timing.

  In the fourth embodiment, the voice data VD has a reset condition RC recorded in the sequence list SL. As a result, the user can reset (return to the top of) the index of the sequence list by performing an operation that satisfies the reset condition at a desired timing.

  FIG. 16 is a flowchart showing the note-on process executed in step SA6 of FIG. 5 in the fourth embodiment of the present invention.

  The fourth embodiment can be realized by replacing steps SB6 to SB17 with steps SB401 to SB404 described later in the note-on process shown in FIG. 6 of the first embodiment. In addition, since the process of step SB1-SB3 and SB18-SB21 is the same as that of a 1st Example, illustration and its description are abbreviate | omitted.

  In step SB4, the mode information MI of the voice data VD selected in step SA3 in FIG. 5 is referred to, and it is determined whether or not the voice should be the cycle sound “WaveCycle”. If it is a voice to be sounded in a cycle, the process proceeds to step SB401 indicated by an arrow of YES, and if it is not a voice to be sounded in a cycle, the process proceeds to step SB5 indicated by an arrow of NO. In step SB5, an element corresponding to another sound generation mode (such as normal sound generation other than cycle sound generation) is selected, and the process proceeds to step SB18.

  In step SB401, it is determined whether or not a reset condition is satisfied. If the reset condition is satisfied, the process proceeds to step SB402 indicated by a YES arrow, the index IX of the sequence list of the pronunciation management data MD in FIG. 15 is reset (the index is returned to the top), and the process proceeds to step SB403. If the reset condition is not satisfied, step SB402 is skipped and the process proceeds to step SB403, as indicated by the NO arrow. The reset condition in the present embodiment is “the performance style switch state variable changes”, that is, the detection of the ON / OFF operation of the performance style switch. By this processing, it is possible to operate the performance style switch at a desired timing to reset the index and to sound the elements of the sequence from the beginning.

  In step SB403, the index IX of the sequence list of the pronunciation management data MD in FIG. 15 is advanced by 1, and then the process proceeds to step SB404. When the index IX indicates the last element information EL of the sequence list SL, the index is returned to the top.

  In step SB404, the element (element information EL) indicated by the index IX of the sequence list of the pronunciation management data MD in FIG. 15 is selected. Thereafter, the process proceeds to step SB18 in FIG.

  As described above, according to the fourth embodiment of the present invention, the user can reset (return to the top) the index of the sequence list by performing an operation that satisfies the reset condition at a desired timing.

  The embodiments of the present invention can be combined as appropriate. For example, the first embodiment and the second embodiment may be combined to switch the sequence list according to the sound range, and the special tone generation element may be selected when the rendition style switch is ON or at a specific velocity. Further, for example, the reset condition according to the fourth embodiment can be set for the first to third embodiments.
