  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of a remix device according to an embodiment of the present invention. As will be described later, the remix device according to the present embodiment performs slice processing in addition to (loop) remix processing, but will be referred to as “remix device” for convenience.

  As shown in the figure, the remix device of this embodiment includes a keyboard 1 for inputting pitch information, a panel operator 2 having a plurality of operators for inputting various information, and a keyboard 1. A key depression detection circuit 3 for detecting the key depression state of each key, an operation element detection circuit 4 for detecting a depression state of each operation element of the panel operation element 2, a CPU 5 for controlling the entire apparatus, and the CPU 5 A flash memory 6 for storing a control program to be executed, musical sound waveform data, various table data, a RAM 7 for temporarily storing performance data, musical sound waveform data, various input information, calculation results, and the like, and an interrupt in timer interrupt processing A timer 8 for measuring time and various times, a panel display 9 for displaying various information, for example, a liquid crystal display (LCD), a light emitting diode (LED), and the like; A hard disk drive (HDD) that drives a floppy disk drive (FDD) 10 that drives a floppy disk (FD) 20 that is a medium, and a hard disk (not shown) that stores various application programs including the control program and various data. 11, a CD-ROM drive (CD-ROMD) 12 for driving a compact disk-read only memory (CD-ROM) 21 for storing various application programs including the control program, various data, and the like, A MIDI interface (I / F) 13 for inputting a MIDI (Musical Instrument Digital Interface) signal or outputting a MIDI signal to the outside, and a server computer 102 and data via a communication network 101, for example. A communication interface (I / F) 14 for transmitting and receiving, an input terminal IT for inputting an analog musical sound waveform signal from the outside, and an ADC (Analog-to-Digital Converter) for converting an analog musical sound waveform signal into digital musical sound waveform data And a waveform I / O 15 composed of a DAC (Digital-to-Analog Converter) for converting digital musical sound waveform data into an analog musical sound waveform signal, and an analog musical sound signal from the waveform I / O 15 are converted into sound, for example And a sound system 16 such as an amplifier and a speaker.

  The above components 3 to 15 are connected to each other via a bus 17, a timer 8 is connected to the CPU 5, another MIDI device 100 is connected to the MID II / F 13, and a communication network 101 is connected to the communication I / F 14. And the sound system 16 is connected to the waveform I / O 15.

  The waveform I / O 15 has an input terminal for an analog tone waveform signal (for example, a tone waveform signal generated by a user playing a musical instrument or a tone waveform signal reproduced by a user using various players such as a CD player or a record player). Input from the IT, the input analog musical sound waveform signal is sampled by the ADC, and the sampling data is stored in a sampling data storage area provided in the flash memory 6 or the RAM 7, thereby generating musical tone pattern data. At this time, header information is automatically generated by a user instruction or added to the head of the musical tone pattern data. Examples of the contents of the header information include the name of the musical tone pattern data, the sampling frequency, the number of bits, the pitch, the number of channels, and the like. In the present embodiment, the musical sound waveform signal that is the basis of the musical sound pattern data is described as an analog signal. However, this is merely for convenience of description, and may be digital data. However, it goes without saying that when digital musical sound waveform data is input, sampling by the ADC is not necessary.

  Further, the waveform I / O 15 converts new musical tone pattern data (digital data) generated by a loop remix process or a slice process, which will be described later, into analog data by the DAC, and sends the analog data to the subsequent sound system 16.

  That is, the waveform I / O 15 samples analog musical sound waveform signals, converts them into digital musical sound waveform data and stores them, and converts digital musical sound waveform data generated by loop remix processing or slicing processing into analog musical sound waveform signals. It mainly performs two types of functions of transfer, and the generation of digital musical sound waveform data is left to the CPU 5 exclusively. That is, in this embodiment, a so-called soft sound source that generates digital musical sound waveform data by software processing executed by the CPU 5 is employed as the sound source. Of course, the present invention is not limited to this, and a so-called hardware sound source that generates digital musical sound waveform data using dedicated hardware may be employed.

  Although not shown, the panel operator 2 includes eight pads and two knobs. When an analog musical sound waveform signal from the outside is sampled by the waveform I / O 15 and stored in the flash memory 6 or the RAM 7, the sampling waveform data is assigned to one of the plurality of pads. Then, when the user operates one of the pads, the sampling waveform data assigned to the pad is read and reproduced. The operation of the knob will be described later. Needless to say, the number of pads and knobs is not limited to the above-mentioned number. Further, instead of the pads and knobs, other operating elements are used so that the operating elements perform the same operation. May be.

  As described above, the hard disk of the HDD 11 can also store the control program executed by the CPU 5. If the control program is not stored in the flash memory 6, the hard disk stores the control program in the RAM 7. The CPU 5 can be operated in the same manner as when the control program is stored in the flash memory 6. In this way, control programs can be easily added and upgraded. Further, the HDD 11 may store waveform data used for generating musical sound waveform data by the software sound source (or the hard sound source) that is the sound source of the present embodiment. In this case, the software sound source (or hardware sound source) reads out the waveform data from the HDD 11 to the waveform data storage area of the RAM 7 before generating the digital musical sound waveform data.

  The control program and various data read from the CD-ROM 21 of the CD-ROM drive 12 are stored in the hard disk in the HDD 11. As a result, a new installation or version upgrade of the control program can be easily performed. In addition to the CD-ROM drive 12, a device for using various types of media such as a magneto-optical disk (MO) device may be provided as an external storage device.

  The MIDII / F 13 is not limited to a dedicated one, and may be configured by a general-purpose interface such as RS-232C, USB (Universal Serial Bus), IEEE 1394 (Eye Triple E 1394). In this case, data other than MIDI messages may be transmitted and received simultaneously.

  As described above, the communication I / F 14 is connected to a communication network 101 such as a LAN (Local Area Network), the Internet, or a telephone line, and is connected to the server computer 102 via the communication network 101. When the above programs and various parameters are not stored in the hard disk in the HDD 11, the communication I / F 14 is used to download programs and parameters from the server computer 102. A computer serving as a client (in this embodiment, a remix device) transmits a command for requesting downloading of a program and parameters to the server computer 102 via the communication I / F 14 and the communication network 101. Upon receiving this command, the server computer 102 distributes the requested program and parameters to the computer via the communication network 101, and the computer receives these programs and parameters via the communication I / F 14 and receives them in the HDD 11. Downloading is completed by accumulating on the hard disk.

  In addition, an interface for directly exchanging data with an external computer or the like may be provided.

  As can be seen from the above configuration, the remix device according to the present embodiment is constructed on a general-purpose personal computer. However, the present invention is not limited to this, and the remix device includes only minimum elements that can implement the present invention. It may be constructed on a dedicated device.

  The outline of the control process executed by the remix apparatus configured as described above will be described first with reference to FIGS. 2 to 5 and then in detail with reference to FIGS.

  When the user operates any one of the eight pads, the musical tone pattern data assigned to the pad is read from the sampling data storage area of the flash memory 6 or the RAM 7, for example, the panel display 9 is displayed. When data for one phrase is designated by the user from among them, the CPU 5 divides the data for one phrase equally into eight musical tone segment data, and each musical tone segment data after this division is divided. A start address (the address indicated by the upward arrow in FIG. 2) is added to the header information of the musical tone pattern data. In the present embodiment, data for one phrase is designated as musical tone pattern data. However, the present invention is not limited to this, and may be longer or shorter than one phrase. Furthermore, although the musical tone pattern data is configured to be specified by the user as described above, the present invention is not limited to this, and the CPU 5 may automatically specify the musical tone pattern data.

  And based on each start address, by changing the reading order and the reading mode of each musical tone segment data, (1) loop remix processing and (2) slice processing are performed as follows. Realize. In the present embodiment, a loop remix mode for performing the loop remix process of (1) and a slice mode for performing the slice process of (2) are provided, and switching between these modes makes it possible to Processing is realized.

(1) Loop Remix Processing FIG. 3 is a diagram showing an example of the reading order type (TYPE) of each musical tone segment data. The data indicating the reading order (for example, when TYPE = 4, 3 , 4, 1, 2, 7, 5, 6, 7 (where each integer value constituting the number sequence indicates the order of each piece of musical piece data constituting the original musical tone pattern data (original waveform)) Is stored in the flash memory 6 as table data. In the same figure, examples of 10 different types of reading orders of TYPE = 1, 2,..., 10 are described, and the arrangement is such that the reading order becomes more complex as the number set as TYPE increases. Has been. In this case, “complicated” means that the order difference becomes larger than the original reading order (TYPE = 1). For example, there are more musical piece data whose reading order is different from the original reading order. That the order difference between the replaced musical tone segment data and the original reading order of the musical tone segment data is increased, the unit of the musical tone segment data to be replaced is reduced, or any combination thereof. Correspond. As the order becomes more complex, the auditory difference from the original musical tone pattern data increases.

  Further, in FIG. 3, there is a place where one piece of musical piece data is divided into two or four (the second of TYPE = 5, the fourth of TYPE = 6, etc.). This shows that the musical piece segment data to be selected and reproduced is changed to another musical piece segment data during reproduction in the single readout period.

  FIG. 4 is a diagram showing an example of the change (VARI) of the reading manner of each musical tone segment data. Data representing these reading manners (for example, when VARI = 3, R: 1, 5; S : Correspondence data (where “R” is the correspondence between the read mode (R, S) and 2, 7 and 8) and the order of the musical tone segment data constituting the original musical tone pattern data to be read in the read mode Means that the musical segment data should be read in the reverse direction, that is, in the direction of the start address from the end address of the musical segment data, and “S” is the start address of the musical segment data Means that it should not be read from the central address to the center address, that is, silence should be set, and each numerical value represents the data of each musical piece segment constituting the original musical tone pattern data (original waveform). Shows a turn)) is, as table data, stored in the flash memory 6. In the same figure, examples of 10 different types of reading modes with VARI = 1, 2,..., 10 are described, and the arrangement is such that the reading mode becomes more complex as the number set as VARI increases. Has been. In this case, “complicated” means that the mode difference from the original reading mode (VARI = 1) becomes large. For example, the number of musical piece segment data read in the reverse direction increases. is there. Here, only two of “reverse direction” and “silence” are illustrated as special readout modes, but in addition, “effect processing such as distortion” and “sampling frequency” are performed for each musical tone segment data. It is also possible to perform mode control such as “lowering the sound to make it lo-fi” or “applying fluctuations in volume and pitch”.

  The user designates the type of reading order using one of the two knobs, and designates the change of the reading manner using the other knob. For example, when the user selects the loop remix mode, the panel display 9 displays a list of the types of readout order and changes in the readout mode shown in FIGS. 3 and 4, respectively. By turning the respective knobs, the type of the target reading order and the change of the reading mode are designated.

  When one of the pads is operated by the user, the musical tone pattern data assigned to the pad is selected, and then the selected musical tone pattern data is repeatedly reproduced. At that time, in response to the change in the type of reading order and the reading mode specified above, reproduction is performed while generating new musical tone pattern data. A feature of the present invention resides in that during the reproduction of musical tone pattern data, instructions for changing the type of reading order and the change in reading mode by the two knobs are received. The change instruction accepted in this way becomes effective when the reproduction of the current musical pattern data is finished and the reproduction of the musical pattern data (so-called loop reproduction) is started again, and is changed during the reproduction of the musical pattern data. In accordance with the change in the type of reading order and the reading mode instructed, loop playback is started, that is, real-time loop remix processing is performed. The reason why such real-time loop remix processing can be performed is that, unlike the conventional remix device, loop remix processing is performed using a pointer (start address pointer) with a small control processing amount. .

(2) Slice Processing FIG. 5 is a diagram showing an example of a division type (TYPE) when dividing musical tone pattern data for one phrase in a slice processing into a plurality of musical tone segment data. In the case of TYPE = 4, for example, 0.5, 0.5, 1, 0.5, 0.5, 1, 0.5, 0.5, 1 , 0.5, 0.5, and 1 (however, each numerical value constituting the sequence is a musical unit data length, that is, a ratio when 1/8 phrase length is a unit length (“1”)). Are stored in the flash memory 6 as table data. In the figure, examples of ten different types of segment areas of TYPE = 1, 2,..., 10 are described, and the segment areas become more complex as the number set as TYPE increases. Is arranged. In the figure, the hatched area merely indicates that the area is a unit length, and has no further meaning.

  The user designates the type of the segment area using one of the two knobs. For example, when the user selects the slice mode, a list of segment areas shown in FIG. 5 is displayed on the panel display 9, and the user turns the knob to select the type of the target segment area. specify.

  Of the two knobs, the other knob is used to designate the ratio of the partial area to be reproduced (hereinafter referred to as “RATE value”) in each segment area of the designated type. Specifically, as the knob is turned in a predetermined direction, the length of the partial area to be reproduced in each segment area approaches the length of the segment area (segment area length). While the ratio is set, the ratio is set in the direction in which the length of the partial area to be reproduced in each segment area approaches zero as it is turned in the opposite direction.

  When one of the pads is operated by the user, the musical tone pattern data assigned to the pad is selected, and then the selected musical tone pattern data is repeatedly reproduced. At that time, reproduction is performed while generating new musical tone pattern data (slice pattern data) in accordance with the type of the specified segment area and the ratio of the segment area to be reproduced. The feature of the present invention is that during the reproduction of the musical tone pattern data, instructions for changing each of the type of the segment area and the ratio of the partial area to be reproduced by the two knobs are received. The change instruction received in this way becomes effective when starting loop reproduction, and changes according to the type of segment area in which the change instruction is given during reproduction of the musical tone pattern data and the ratio of the partial area to be reproduced. Loop playback is started, that is, real-time slice processing is performed. The reason why such real-time slicing processing can be performed is that, unlike a conventional slicing apparatus, slicing processing is performed by using a pointer (start address pointer) with a small amount of control processing.

  Next, the loop remix process and the slice process will be described in detail.

  FIG. 6 is a flowchart showing a procedure of a main routine executed by the remix device of the present embodiment, particularly the CPU 5.

  In the figure, first, initial settings such as clearing the RAM 7, resetting various ports, setting a default tempo, and the like are performed (step S1).

  Next, an event is detected (step S2). When an event is detected, processing corresponding to the event is performed (step S3), and then the process returns to step S2. On the other hand, when no event is detected, It returns to step S2 as it is. That is, when the initial setting in step S1 is completed, the loop process of either step S2-> S3-> S2 or step S2-> S3-> S4-> S2 is repeatedly executed.

  In the present embodiment, the multi-task operation is performed as the entire loop process, so even if the detected event is being processed in step S4, this process is performed in parallel. The next event detection process, that is, the process of step S2 is performed.

  FIG. 7 is a flowchart showing the procedure of the knob detection value change process. This process is one of the processes in response to the detected event in step S4, and is activated in response to an event that occurs when at least one of the two knobs is turned.

  In the same figure, the operation amount of each knob is detected, and the detected values are obtained as areas v1 and v2 (hereinafter referred to as “knob operation amounts v1”, respectively) secured at predetermined positions in the RAM 7. ”And“ knob operation amount v 2 ”) (step S 11), and the process ends.

  FIG. 8 is a flowchart showing a procedure of pad-on event processing in the loop remix mode. This process is also one of the processes according to the detected event in step S4, and when the user operates any one of the eight pads when the loop remix mode is selected. It is activated in response to a pad-on event that occurs.

  In the figure, first, a phrase corresponding to the operated pad, that is, musical tone pattern data is selected (step S21).

  Next, the type (TYPE) of reading order of each musical piece segment data described with reference to FIG. 3 is set according to the knob operation amount v1, and according to the knob operation amount v2, using FIG. The change (VARI) of the reading mode of each musical tone segment data described is set (step S22). Specifically, according to the knob operation amount v1, any value from “1” to “10” is set in the area TYPE (hereinafter, this content is referred to as “TYPE value”), and the knob operation amount v2 is set. In response, any value from “1” to “10” is set in the area VARI (hereinafter, this content is referred to as “VARI value”).

  Next, an index i indicating one of the 1 to 8 segment ranges of the data representing the reading order (FIG. 3) or the data representing the reading mode (FIG. 4) is used to identify the first segment. Is initialized (i ← 1) (step S23). Then, the musical tone segment data indicated by the segment range data indicated by the index i is selected from the data representing the reading order according to the TYPE value set in step S22 (step S24). Here, the selection is specifically the start address (when the i-th segment range of the data representing the read mode indicated by the VARI value indicates forward reproduction) or the end address ( Only when a read pointer (for example, a read pointer formed by software) for reading out the musical tone pattern data is matched with the reverse direction reproduction (when reverse reproduction is indicated).

  And the data for 1/2 length are reproduced | regenerated among the said musical tone segment data (step S24). At this time, from the position of the read pointer set in step S24, the read pointer according to the read mode indicated by the data in the segment range specified by the index i among the data representing the read mode corresponding to the VARI value. Play music piece data while proceeding. Specifically, for example, when TYPE = 5 and VARI = 3 are set and i = 1, the read pointer is set to the end address of the first musical tone segment data, and from the address position. In the reverse direction, that is, in the direction of the start address of the musical tone segment data, the musical tone segment data is reproduced for ½ length.

  Next, it is determined whether or not reselection is necessary (step S26). When reselection is necessary, the data of the i-th segment range of the data indicating the reading order specified by the TYPE value is divided into two parts, the first half and the second half, and the musical tone segment data different in the first half and the second half Is designated, and corresponds to the case where the second or eighth musical piece segment data is reproduced when TYPE = 5 is set. When reselection is necessary in step S26, the musical tone segment data specified in the latter half of the segment range is selected (step S27) after step S28, and reselection is not necessary, as in step S24. Sometimes, the process proceeds to step S28 as it is.

  In step S28, with respect to the reselected musical piece segment data, in the same manner as in step S25, from the position of the read pointer set in step S27, the data representing the read mode corresponding to the VARI value is displayed. According to the reading mode indicated by the data of the segment range specified by the index i, the musical segment data that is not re-selected is reproduced for ½ length, from the position of the read pointer at the completion of reproduction in step S25, Of the data representing the reading mode corresponding to the VARI value, the data corresponding to 1/2 length is reproduced according to the reading mode indicated by the data in the segment range specified by the index i. In the reselection processing of the musical tone segment data in step S27, only the read pointer is reset, and the processing in step S28 is not performed on the reselected musical tone segment data. The same applies to data.

  Next, in the panel operator 2, it is determined whether or not a stop switch (not shown) has been operated to give an instruction to stop this pad-on event processing (step S29). When the stop switch is not operated, the phrase It is determined whether or not the musical piece data reproduction process has been completed until the end (step S30). In this embodiment, this determination corresponds to determining whether the segment range indicated by the index i has reached the final segment range (whether i = 8). If it is determined in step S30 that the musical piece segment data has not reached the end of the phrase, i.e., i ≠ 8, i is incremented by "1", and then the process returns to step S24 to return to steps S24 to S24. While the process of S30 is repeated, when the musical piece data reproduction process reaches the phrase end, i.e., i = 8, during the process of steps S22 to S31, at least one position of the two knobs. It is determined whether or not has changed (step S32).

  When the position of at least one of the two knobs is changed in step S32, the process returns to step S22, the TYPE value and the VARI value are reset, and loop reading is performed based on the reset value. When the position of any of the knobs does not change, the process returns to step S23, and loop reading is performed again based on the currently set TYPE value and VARI value.

  On the other hand, when the stop switch is operated in step S29, the pad-on event process is terminated after the sound that is currently sounding is muted (step S33).

  FIG. 9 is a flowchart showing a procedure of pad-on event processing in the slice mode. This process is also one of the processes according to the detected event in step S4, and occurs when the user operates one of the eight pads when the slice mode is selected. It is activated in response to a pad on event. This pad-on event process can be realized by changing a part of the procedure of the pad-on event process in the loop remix mode of FIG. Therefore, in FIG. 9, the same step numbers are assigned to steps that perform the same processing as in FIG. 8, and the description thereof is omitted.

  In FIG. 9, first, as in step S21 of FIG. 8, a phrase corresponding to the operated pad is selected.

  Next, according to the knob operation amount v1, any one of data representing a plurality of division modes (regions of divided musical tone segment data) when the musical tone pattern is divided as described with reference to FIG. Is set, and the RATE value (for example,% value) is set according to the knob operation amount v2 (step S41). Further, an index i indicating one of a plurality of segment areas in the data representing the division mode (FIG. 5) is initialized (i ← 1) in order to identify the first segment area (step 1 ←). S23).

  Then, the segment length of the segment unit indicated by the index i is obtained from a plurality of segment regions of the data representing the division mode according to the TYPE value, and the segment unit length of the musical segment unit to be reproduced next (Step S42). Specifically, for example, in the state where TYPE = 5 is set, when i = 1 to 4, the segment length is determined to be 1/2, and when i = 5, the segment length is set to 1. It is determined.

  And it reproduces | regenerates for the length according to the RATE value among all the segment lengths (step S43). Specifically, when TYPE = 5 is set and RATE = 50% is set, the first half of the musical tone segment data for the first ½ length when i = 1 is set. The ¼ length is played back, and the musical piece segment data is not played back in the latter ¼ length, and there is a ¼ length of silence (only time is counted). When i = 2, only the first quarter length of the second half length musical tone segment data is reproduced, and the second quarter length is silenced. Thereafter, similarly, after reproduction corresponding to i = 3 and 4 is performed, when i = 5, the musical piece segment data for the first half of the musical piece segment data for the first one of the fifth length. Is played, and the latter half length becomes silent. Thereafter, similarly, each piece of musical piece data divided based on the data indicating the division mode according to the TYPE value is first reproduced from the beginning to the position indicated by the RATE value, and the musical piece unit data The rest of the period is silent. Although only the case where the RATE value is 50% has been described here, the RATE value can be changed from 0% to 100% according to the knob operation amount v2. For example, when the RATE value is 40%, 2/5 is reproduced from the head of each piece of musical tone segment data, and the remaining 3/5 is silent.

  In the present embodiment, the explanation has been made by adopting the sampling waveform data sampled by the waveform I / O 15 as the musical tone pattern data. However, the present invention is not limited to this, and automatic performance data such as MIDI data may be used. It may be a musical sound waveform used to generate a musical sound such as a sine wave or a sawtooth wave.

  In the present embodiment, not only the slice process but also the loop remix process is configured so that the information indicating the read order does not include an element of chance, but the read order is not limited to this. A part (or all) of the information to be displayed may include an element of chance. Specifically, for example, a random number is generated, and musical tone segment data is selected based on the random number.

  In the present embodiment, the description has been made by paying attention to one musical tone pattern data when one musical tone pattern data is repeatedly reproduced according to the operation of the pad, but this is only for convenience of explanation, In general, when a plurality of pads are operated subsequently, a plurality of musical tone pattern data are reproduced simultaneously. For a plurality of musical tone pattern data to be reproduced at the same time, it is desirable to perform control by two knobs independently for each musical tone pattern data. For this purpose, two knobs may be provided corresponding to each of the plurality of pads. However, this complicates the configuration, so in order to reduce the number of knobs, the control using the two knobs is performed only on the musical tone pattern data of the pad that was last operated, and for the other pads, It is only necessary to hold the operation amounts v1 and v2 of the two knobs when the control with the two knobs is performed last, and to perform the control with the held values. According to this method, it is possible to simultaneously perform control corresponding to an independent knob control amount for each pad while limiting the number of knobs to a small number.

  Further, each mode of the plurality of modes may be controlled on / off so that the plurality of modes can be executed simultaneously. That is, instead of the selection method of selecting only one of the “loop remix mode” and “slice mode” described in the present embodiment, the mode may be turned on / off for each mode. By doing so, the special effect of the “loop remix mode” can be realized with the special effect of the “slice mode”. In that case, if two knobs as described in the present embodiment are provided independently for each mode, independent control can be performed for each mode even if it is left as it is. However, if an independent knob is provided for each mode, the configuration becomes complicated. To reduce the number of knobs, when each mode is turned off for each mode, the knob at that point in time is used. The operation amounts v1 and v2 are held, and when the mode is turned on thereafter, the control is performed with the held knob operation amount regardless of the knob operation amount at that time. Then, only when the knob is operated after that, the control based on the detected knob control amounts v1 and v2 is performed only for the last turned on mode. According to this method, it is possible to simultaneously perform control corresponding to an independent knob operation amount for each mode type while limiting the number of knobs to a small number.
