Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an overdubbing editing apparatus for editing performance information while inputting new performance data simultaneously with reproduction in an electronic musical instrument.
[0002]
[Prior art]
Overdubbing is a technique for recording other performance data on another new track while reproducing already recorded performance data, and is widely used in recording and the like. A similar technique is also used when the sampling machine successively superimposes the previous sampling sound.
[0003]
Japanese Patent Laid-Open No. 7-325570 discloses such a structure for overdubbing, and as shown in FIG. 8, the previous performance data is stored in the first storage means 201 to create a new performance. When data is input, it is merged with the previous performance data by the merging means 202, stored in the second storage means 203, and repeated as necessary to enable overdubbing.
[0004]
[Problems to be solved by the invention]
In the above configuration, performance data is not stored separately on separate tracks, so past history cannot be unraveled during editing, performance data is separated, unnecessary performance data is deleted, etc. There is a problem that it cannot be done. Even if the performance data is recorded in the production process, there is performance data that is not necessary for the finished work. When overdubbing is performed, if it is not easy to delete the performance data, it is necessary to re-enter the performance data from the beginning. Therefore, it must be complicated.
[0005]
The present invention was devised in view of the above-described problems of the prior art, and enables the input block to be sorted in the overdubbing editing process so that unnecessary performance data can be deleted and edited. An overdubbing editing device for electronic musical instruments is to be provided.
[0006]
[Means for Solving the Problems]
  Therefore, the configuration of the electronic musical instrument overdubbing editing apparatus according to the present invention is as follows.
  A plurality of data buffers for storing arbitrary performance data;
  Data distribution means for storing performance data in each data buffer;
  Performance data reading means for reading performance data from the data buffer and outputting it;
  Loop processing for inputting and outputting performance data to the data buffer simultaneously by looping a predetermined number of measures. When a new loop is started, an empty data buffer is selected and the data distribution is performed. The performance data is stored by the means, and when there is a data buffer in which the performance data is already stored, the performance data is read by the performance data reading means simultaneously with the start of the loop, and is output. Means,
  Performance data recording means for recording performance data stored in the data buffer for each data buffer or by merging all performance data;
Have
The control means reads out performance data recorded in the performance data recording means and stores it in one or more data buffers, and then inputs new performance data to the remaining empty data buffers.
This is a basic feature.
[0007]
In the above configuration, the performance data to be input is temporarily stored in separate data buffers during editing, and the performance data for a predetermined measure (in units of one loop) once stored in the data buffer is stored in a new loop. Then, the performance data is read out by the performance data reading means and then output, so that overdubbing can be performed in which another performance data is recorded on another new track while the already recorded performance data is reproduced. It becomes like this. As a result, the performance data stored in each data buffer is independent during editing, and each performance data can be freely deleted or not output to the outside (for example, music is not reproduced). Become.
[0008]
In this configuration, every time a new loop is entered by the control means, an empty data buffer is selected, and the performance data is stored therein by the data distributing means, so that the operator can use completely empty data. In general, overdubbing can be freely repeated without worrying about the existence of an empty data buffer, except when the buffer runs out. Even when there is no more empty data buffer, it is possible to secure an empty data buffer by selecting or deleting unnecessary or unimportant performance data in the data buffer or transferring it to another recording means. It becomes possible.
[0009]
  In this configuration,Performance data recording means for recording performance data stored in the data buffer for each data buffer or by merging all performance data, and recording all of the performance data at the end of editing. It was decided. If the recording format is set to be recorded for each data buffer, the history in the previous editing can be unraveled when editing again later, and the subsequent editing work can be performed easily.And when editing again, like this configuration,The previous performance data recorded in the performance data recording means is read out, stored in one or more data buffers, and new loop performance data is input to the remaining empty data buffer to resume editing.Will do.
[0010]
  During overdubbing, the performer performs the performance in accordance with the reproduced sound of the performance data for one loop already recorded, and inputs the performance data related to the new loop. It is necessary to be able to sense at the same time. for that reason,Claim 2In this configuration, the performance data read out by the performance data reading means by the control means is output together with the input performance data of the new loop, so that the performance data is reproduced by appropriate reproduction means. If you do, you will be able to know your own performance.
[0011]
  During overdubbing, it is more convenient for editing to play various combinations of performance data, and to select the playback of the stored performance data without deleting the performance data. good. for that reason,Claim 3In the configuration, when the performance data stored in the data buffer is read and output by the performance data reading means, it can be selectively output in units of the data buffer.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an electronic musical instrument to which the configuration of an embodiment of an overdubbing editing apparatus of the present invention is applied.
[0013]
In the above configuration, the microprocessor 101, the RAM 102, the ROM 103, the external storage device 104, the keyboard 105 connected via the keyboard interface 105a, the MIDI interface 106, and the panel interface 107a are connected to the bus 100.

[0015]
The RAM 102 temporarily stores data necessary for executing the program, plays a role as a working memory, and merges the contents of the data buffers 1a to 1e and the data buffers 1a to 1e of FIG. It is also used as a storage track for later performance data storage means 5.
[0016]
The ROM 103 stores timbre data for designating the timbre in the tone generator circuit 108, address information for designating the readout address of the waveform data, an envelope coefficient for generating an envelope waveform, a control program, and the like. Various types of information are exchanged via the bus 100, and the operation of the entire electronic musical instrument is controlled based on a control program stored in the ROM 103 using a register or the like set in the RAM 102.
[0017]
The external storage device 104 is configured by a hard disk drive HDD, a flexible disk drive FDD, or the like in this configuration, and the contents of the performance data recording means 5 on the RAM 102 in this configuration are stored or read as appropriate in this external storage device 104. Or The configuration is not limited to the configuration of these disk drives, and any configuration may be used as long as data can be recorded even after the power is turned off, such as MO and flash ROM.
[0018]
The keyboard 105 is one of the means for inputting performance data, and when the keyboard 105 is scanned by the keyboard interface 105a, thereby detecting each key depression (key-on) and key release (key-off) event, The key code of the key that was found is output.
[0019]
The MIDI interface 106 is also configured as one means for inputting performance data, and it is possible to input performance data from outside the keyboard 105.
[0020]
The panel switch 107 includes a mode selection switch for selecting a pattern editing mode for overdubbing, a reproduction switch SW11a to 11e (to be described later) for instructing which data buffer 1a to 1e is turned on / off, and other switches. The panel interface 107a detects an event of each switch operation of the panel switch 107.
[0021]
The tone generator circuit 108 reads out musical sound waveform data from a waveform storage ROM (not shown) based on performance data stored in the data buffer 1 to perform sampling interpolation and filter processing, and also applies an envelope to the waveform data. The tone signal generated by this configuration is output to the next sound system 109.
[0022]
The sound system 109 has a configuration including an amplifier 109a and a speaker 109b, and is configured to amplify a musical sound signal output from the sound source circuit 108 and to externally output a musical sound. However, when the tone signal output from the tone generator circuit 108 is digital, it is first converted into an analog signal by a D / A conversion circuit (not shown) and then output to the amplifier 109a side.
[0023]
As described above, the data buffers 1a to 1e are composed of the RAM 102, and are logically divided into a plurality of areas (Edit BuF 0 to 4) so that arbitrary performance data can be stored. Yes. In FIG. 2, recording LEDs 10 a to 10 e are provided on the input side of the data buffers 1 a to 1 e to indicate that the data is input when performance data is stored. On the output side, there are reproduction switches SW11a to 11e for turning ON / OFF the output of the stored performance data and the output when the performance data stored in each data buffer is read out. Reproduction LED12a-12e which shows this is provided. These recording / playback LEDs and switch SW are constituted by the panel switch 107 and LEDs installed in the vicinity thereof.
[0024]
As described above, the data distribution means 2 is a data storage distributor constituted by the microprocessor 101. In this configuration, the data distribution means 2 is assigned to each of the data buffers 1a to 1e based on the selection of the empty data buffer by the control means 4. Performance data can be stored.
[0025]
The performance data reading means 3 is similarly composed of the microprocessor 101, reads performance data from the data buffers 1a to 1e, and outputs the performance data to the bus 100. As described above, it is possible to prevent performance data from being read from any data buffer 1a to 1e by the operator turning off the switches SW11a to 11e.
[0026]
The control means 4 is also composed of a microprocessor 101 and controls a loop process for looping a predetermined number of bars and simultaneously inputting / outputting performance data to / from the data buffer. When performance data of a new loop is input from the interface 106, an empty one is selected from the data buffers 1a to 1e, and the performance data is stored in the data distribution means 2. If there are data buffers 1a to 1e in which performance data is already stored, the performance data reading means 3 reads the performance data simultaneously with the start of the loop and outputs it to the bus 100.
[0027]
The performance data recording means 5 comprises a part of the RAM 102, and the performance data once recorded there is permanently recorded in the external storage device 104. The performance data recording means 5 is logically divided into a plurality of tracks and is stored in the data buffers 1a to 1e based on a pattern edit mode end signal from the panel switch 107 or an instruction from the microprocessor 101. All the performance data can be merged and recorded on one track, or can be recorded on each track separately by the data buffers 1a to 1e.
[0028]
In FIG. 2, a first adder 6 is provided on the output side of the performance data read from the data buffers 1a to 1e so that the outputs of the performance data can be merged there. The performance data merged here and the newly input performance data are further merged by the second adder 7 and output to the tone generator circuit 108 via the bus 100, and the musical sound and sound are output from the sound system 109. Is output.
[0029]
FIG. 3 is a flowchart showing a processing flow by the control means 4 when processing according to this configuration is performed. When the power switch is turned on, the microprocessor 101, the RAM 102, the keyboard interface 105a, the MIDI interface 106, the panel interface 107a, the tone generator circuit 108, and the sound system 109 connected to the bus 100 are initialized (step S101). .
[0030]
Next, a panel switch event is detected (step S102). If there is a switch event (step S102; Yes), an event in the pattern edit mode is detected (step S103). When event detection in the pattern edit mode is performed (step S103; Yes), a pattern edit process (step S104) described later is performed, and the process returns to step S102. On the other hand, when the panel switch event is not detected in step S102 (step S102; No), the process proceeds to the normal mode after step S106. If event detection in the pattern edit mode is not performed in step S103 (step S103; No), processing corresponding to other panel switches is performed (step S105), and then the process proceeds to the normal mode in step S106 and thereafter.
[0031]
In the normal mode, an event of a normal key switch is detected (step S106), and if there is this key switch event (step S106; Yes), a normal key-on is detected based on the event (step S107). If this normal key-on is detected (step S107; Yes), a sound generation process (step S108) is performed. If the reverse (step S107; No), a mute process is performed (step S109), and then the process returns to step S102. To do. On the other hand, if no normal key switch event is detected in step S106 (step S106; No), the process returns to step S102.
[0032]
4 to 7 are flowcharts showing the processing flow of the pattern editing process (step S104). First, all of the recording (Record) LED and the reproduction (Play) LED are cleared (step S111), and the performance data stored therein is read from the logical track of the performance data recording means 5 to the data buffer. Is displayed (step S112; Yes), the contents of the designated i-th recording track are copied to the data buffer 1a (Edit BuF 0) (step S113). Then, for overdubbing the performance data of the new loop, a value for designating the data buffer 1b (Edit BuF 1) is set in the buffer input management register (INPBUFreg) (INPBUFreg = 1), and further the data buffer 1a (Edit BuF 0). ) Is turned on, and the recording LED of the data buffer 1b (Edit BuF 1) is turned on (step S114). On the other hand, if there is no read instruction in step S112 (step S112; No), the data buffer 1a (Edit BuF 0) is cleared (step S115), and buffer input management is performed for overdubbing the performance data of the first loop. A value for designating the data buffer 1a (Edit BuF 0) is set in the register (INPBUFreg) (INPBUFreg = 0), and the recording LED of the data buffer 1a (Edit BuF 0) is turned on (step S116). . After step S114 or S116, the data buffers 1b to 1e (Edit BuF 1 to 4) are cleared (step S117), and a loop management register (Loop BAR reg) that specifies how many loops are to be looped during editing is set. Is performed (step S118).
When the performance data is read from the logical track in step S112, the loop management register stores the loop management data of the performance data as it is, but when the recording is started from scratch as in step S115, the loop management register is the default. Is set to 4 (meaning 4 bars). The contents of the set loop management register are displayed on the panel, the user can see and change the value of the panel, and selectable values are 1, 2, 4, 8, and 16. . The setting of the Loop BAR reg in step S118 means a series of these processes.
[0033]
Next, it is detected whether or not new performance data is input, that is, whether or not an instruction to start recording has been given (step S121). If such an instruction has been given (step S121; Yes), a bar and time signature management register (BAR reg, BEAT reg) is cleared (step S122). In this edit mode, a key switch event is detected (step S123), and if there is a key switch event (step S123; Yes), it is detected whether there is an empty data buffer (step S124). If there is no empty data buffer (step S124; No), a warning sound is generated for 0.5 seconds (step S129). If there is an empty data buffer (step S124; Yes), the key switch event data is stored together with the time data in the data buffer (Edit BuF) designated by the buffer input management register INPBUFreg (step S125). Further, it is detected whether the key switch event detected in step S123 is a key-on event or a key-off event (step S126). If this key-on is detected (step S126; Yes), the sound generation process is performed. (Step S127) is performed, and in the opposite case (Step S126; No), a mute process is performed (Step S128). On the other hand, if there is no such instruction in step S121 (step S121; No), it is detected whether or not there is an instruction to start playing performance data stored in the data buffer (step S130). If this is the case (step S130; Yes), the bar and time signature management register clear process is performed (step S131). After the steps S127, S128, S129, and S131 and when the key switch event is not detected in step S123 (step S123; No), the process proceeds to the next step S141 and subsequent steps. If no reproduction start instruction is detected in step S130 (step S130; No), the process proceeds to a data save mode in step S161 and later described later.
[0034]
Furthermore, in order to manage the number of measures and beats of the phrase currently overdubbed, the management registers for the measures and beats (BAR reg, BEAT reg) according to the contents of the timer register to be interrupted Is updated (step S141). Then, it is detected whether or not the value of the bar management register (BAR reg) has reached the value of the loop management register (Loop BAR reg) (step S142). If the value has reached that value (step S142; Yes) In order to return to the beginning, the value of the loop management register (Loop BAR reg) is subtracted from the value of the bar management register (BAR reg) to obtain the value of the bar management register (BAR reg) (step S143). When returning to the top of the loop, it is detected whether the current mode is the recording mode (step S144). If it is the recording mode (step S144; Yes), the data buffer indicated by the buffer input management register INPBUFreg. It is checked whether or not key information is stored in (Edit BuF) (step S145). Then, it is detected whether the performance information is stored or empty in the data buffer (Edit BuF) being used (step S146). If the performance information is stored (step S146; No), the buffer input management register ( INPBUFreg) is incremented (step S147), and it is checked whether there is an empty data buffer (step S148). If there is no more free data buffer (step S148; No), a warning sound is generated for 0.5 seconds (step S149). If there is an empty data buffer (step S148; Yes), the reproduction (Play) LED of the data buffer (Edit BuFi) that has been input so far is turned on, and the data buffer (Edit BuF j) to be input in the future is turned on. The recording LED is turned on, and the recording LED of the data buffer (Edit BuFi) input so far is turned off (step S150). If the value of the bar management register (BAR reg) has not reached the value of the loop management register (Loop BAR reg) in step S142 (step S142; No), and the current mode is the recording mode in step S144. If not (step S144; No), in step S146, if the data buffer being used (Edit BuF) is empty (step S146; Yes), or after the processing of step S150, the process proceeds to the next step S151. .
When the data buffer in use here is empty, it means that the performer did not key on / off during one loop in the recording mode, and the same is true during the next loop. Use the data buffer.
[0035]
Further, it is detected whether or not the reproduction switches SW11a to 11e of each data buffer (Edit BuF) are pressed. If the switches are pressed, the current state of the reproduction LEDs 12a to 12e is reversed and extinguished (step S151). Cut the output of the data buffer that you do not want to let. With respect to the data buffer in which the reproduction LED is lit, a key event corresponding to the timing of the updated bar management register (BAR reg) and time signature management register (BEAT reg) is read and sounded (silenced) (step S152). . Then, it is detected whether or not the processing is being performed in the recording (Record) mode or the reproduction (Play) mode (step S153). If these modes have not ended (step S153; No), it is further detected whether or not the recording mode is set (step S154). If it is in the recording mode (Record) mode (step S154; Yes), the process returns to step S123. On the contrary, if it is in the playback (Play) mode (step S154; No), the process returns to step S141.
[0036]
In step S153, when neither the recording mode nor the playback mode is in operation (that is, when the recording mode or the playback mode is stopped, step S153; Yes), the process proceeds to the data saving mode, and the data buffers 1a to An inquiry display is made as to whether or not the content stored in 1e is finally recorded as performance data (step S161). When there is an instruction (step S160; Yes), the data buffer whose reproduction LED is lit is displayed. The performance data stored therein is saved to the i-th recording track of the designated performance data recording means 5 by merging the key event data in the order of time data (step S162). On the other hand, if there is no instruction to record performance data (step S160; No), the process proceeds to an end check of edit mode (Edit) in step S171 described later. If a playback start instruction is not detected in step S130 (step S130; No), the process proceeds to step S161 to check whether or not performance data that has already been recorded is recorded.
[0037]
It is detected whether or not the pattern edit mode is finished after the save process is finished (step S171). If finished (step S171; Yes), the process is finished. If not (step S171; No), the process is finished. The process returns to step S121.
[0038]
In the configuration of the present embodiment described above, the performance data input respectively is stored in the separate data buffers 1a to 1e during editing, and once the contents once stored in the data buffer enter a new loop, this time the performance data is played. By reading out and outputting the data to the data reading means 3, it is possible to perform overdubbing in which another performance data is recorded in another new data buffer while reproducing the already recorded performance data. Thus, during editing, the performance data stored in the respective data buffers 1a to 1e are independent, so that each performance data can be freely deleted or the musical sound is not reproduced by operating the reproduction switches SW11a to 11e. It is also possible.
[0039]
In this configuration, whenever the performance data is input by the control means 4 by the control means 4, the empty data buffers 1a to 1e are selected, and the performance data is stored in the data distribution means 2 there. Therefore, the operator can repeat overdubbing freely without worrying about the existence of the empty data buffer, except when there is no empty data buffer at all. Furthermore, even when there is no free data buffer, unnecessary data or unimportant performance data in the data buffers 1a to 1e can be selected and deleted, or transferred to another recording means, etc. to secure a free data buffer. can do.
[0040]
Since the performance data stored in the data buffers 1a to 1e is recorded by the data buffer or by merging all performance data, the performance data recording means 5 is provided. The performance data can be stored individually or merged as one song. In particular, if the recording format is set to be recorded separately for each of the data buffers 1a to 1e, when the editing is performed again later, the history during the previous editing can be unraveled, and the subsequent editing work can be performed easily. When editing again, the previous performance data recorded in the performance data recording means 5 is read and stored in one or more data buffers 1a to 1e, and new performance data is input to the remaining empty data buffers. Then you can restart editing.
[0041]
In this configuration, the performance data read by the performance data reading means 3 can be output together with newly inputted performance data by the control means 4, so that the player can know his / her performance state. become able to. As a result, during overdubbing, the performer can perform in accordance with the playback sound of the already recorded performance data, and can input performance data for a new loop, and can simultaneously detect his own performance data. become.
[0042]
In this configuration, when the performance data stored in the data buffers 1a to 1e is read and output by the performance data reading means 3, it can be selectively output in units of the data buffers 1a to 1e. In the middle, various performance data are combined and reproduced, and at this time, reproduction of stored performance data can be freely selected.
[0043]
