[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance information processing device that processes performance information from an electronic musical instrument.

[Conventional technology]

Conventionally, a performance information processing apparatus has been proposed as described below with reference to FIG. That is, it has a performance information generation source A that generates performance information from an electronic musical instrument such as a keyboard device, a sequencer B, a sound source device C, and a sounding body D such as a speaker. When the performance information generation source A is a keyboard device, the performance information generated by the performance information generation source A is a series of key event data. As shown in Figure 2, each key event data that makes up this series of key event data is generated when a key becomes pressed or when a key changes from being pressed to not being pressed. The status is expressed as "1" and "0" in binary representation, the key code is expressed in binary as the pitch assigned to the key when the key is pressed, and the necessary When a key is pressed, a dynamic code representing the speed at which the key is pressed is expressed as a binary number. Sequencer B stores performance information from performance information generation source A (if performance information generation source A is a keyboard device, the above-mentioned series of key event data), and also includes performance information storage/reproduction means ( and performance information storage/reproduction means control means for controlling the performance information storage/reproduction means. The performance information storage/reproduction means control means controls the performance information storage/reproduction means so that the performance information from the performance information generation means A is stored in the performance information storage/reproduction means in the storage mode of the sequencer B. The control mode is described in the case where the performance information from the performance information generation source A is the above-mentioned series of key event data. The event interval code, which is the measurement result expressed in binary numbers from the time point when the key event data is obtained to the time point when the next key event data is obtained, is stored as a series of stored data as shown in Figure 2. This is a mode in which control is performed so that the Furthermore, the performance information storage/reproduction means control means controls the performance information storage/reproduction means so that the performance information stored therein is reproduced in the reproduction mode of the sequencer B. In the case where the performance information stored in the performance information storage/reproduction means is a series of stored data as described above, the control mode is such that the stored data is configured for each stored data in the series of stored data. The status of the event data, the key code, and the dynamic code (if a dynamic code is attached) are the decipherment of the event interval code attached to the event data that constitutes the stored data. Based on this, the stored data is controlled to be read out sequentially from the time when the time until the event data of the next stored data has elapsed. The sound source device C receives the performance information reproduced from the performance information storage/reproduction means of the sequencer B,
A musical tone signal corresponding to the content represented by the sounding body D is supplied to the sounding body D. In this case, when the performance information reproduced from the performance information storage/reproduction means is the above-mentioned series of stored data, the musical tone signal represents the pitch represented by the key code of the key event data. The sounding body D receives a musical tone signal from the sound source device C and emits a musical tone. The above is the configuration of a conventionally proposed performance information processing device. According to the conventional performance information processing device having such a configuration, in the sequencer B, the performance information storage/reproduction means control means controls the performance information storage/reproduction means in the memory mode of the sequencer B.
Since the performance information from the performance information generating means A is controlled to be stored, and the performance information stored in the performance information storage/reproduction means is controlled to be reproduced in the playback mode of the sequencer B, In the memory mode of the sequencer B, the performance information from the performance information generating means A can be stored in the performance information storage/reproduction means.
The performance information stored therein can be reproduced from the reproduction means. Further, since the sound source device C receives performance information reproduced from the performance information storage/reproduction means of the sequencer B, and supplies a musical tone signal corresponding to the content represented by the performance information to the sounding body D, the sounding body D from,
It is possible to obtain a flow of musical tones based on the performance information reproduced from the performance information storage/reproduction means. Furthermore, since it is possible to obtain the flow of musical tones based on the performance information reproduced from the performance information storage/reproduction means from the sounding body D, it is possible to obtain the flow of musical tones based on the performance information reproduced from the performance information storage/reproduction means by the performer or the like. It is possible to determine whether the performance information (hereinafter referred to as previous performance information) is performance information that should be corrected. Performance information is then stored and stored by the performer, etc.
When it is determined that the performance information recorded in the reproducing means is the performance information that should be corrected, new performance information is generated from the performance information generation source A as performance information to replace the previous performance information, and The performance information can be stored in the performance information storage/reproduction means. Furthermore, since the new performance information from the performance information generation source A can be stored in the performance information storage/reproduction means as performance information in place of the previous performance information,
New performance information that replaces the previous performance information can be reproduced from the performance information storage/reproduction means, and therefore musical tones based on the new performance information stored in the performance information storage/reproduction means can be The flow can be obtained from the sounding body D.

[Problem to be solved by the invention]

As described above, according to the conventional performance information processing device, it is possible to cause the performance information storage/reproduction means to store the performance information from the performance information generation source A as the previous performance information, and also to reproduce it. Then, if the reproduced performance information is supplied to the sound source device C to which the sounding body D is connected, the previous performance information stored in the performance information storage/reproduction means is transmitted from the sounding body D. Since it is possible to obtain a flow of musical sounds based on If the previous performance information stored in the performance information storage/reproduction means is the performance information to be corrected, the performance information storage/reproduction means receives, from the performance information generation source A, New performance information can be stored as performance information that replaces previous performance information. However, in the case of the conventional performance information processing device, when the previous performance information stored in the performance information storage/reproduction means is the performance information to be corrected, the performance information stored in the performance information storage/reproduction means The new performance information that replaces the performance information, including the performance information corresponding to the performance information that does not need to be corrected up to the correction start position of the previous performance information that should be corrected, is added to the performance information. Memory·
It is stored in the playback means. By the way, when new performance information is stored in the performance information storage/reproduction means, the performance information storage/reproduction means at least stores the previous performance information stored therein as the performance information to be corrected. Unless the performance information up to the correction start position is deleted, at least the performance information up to the correction start position of the performance information to be corrected is stored. Therefore, when new performance information is stored in the performance information storage/reproduction means, the new performance information is stored in the performance information storage/reproduction means corresponding to the performance information after the correction start position of the previous performance information. Although the performance information is stored, performance information corresponding to the performance information that does not need to be corrected up to the correction start position of the performance information after the new performance information is not stored. - In the reproducing means, performance information including the performance information and the performance information up to the correction start position of the performance information to be corrected is stored as performance information replacing the performance information to be corrected. Therefore, in the case of a conventional performance information processing device, the new performance information is stored in the performance information storage/reproduction means for the performance information that does not need to be corrected up to the correction start position of the previous performance information. It has the disadvantage of being redundant. Therefore, it is an object of the present invention to propose a new performance information processing device that does not have the above-mentioned drawbacks.

The performance information storage/reproduction means is controlled so that (a) the performance information stored in the performance information storage/reproduction means is reproduced as first performance information, and (b) Control is performed so that the second performance information obtained in real time from the performance information generation source by the performance is not stored in the performance information storage/reproduction means, and () in this state, the first
When the performance information reaches the correction start position indicated by the correction start position information set in the correction start position information setting means, from that point on, based on the correction start position information, the actual performance is performed. The second performance information obtained from the performance information generation source in real time is controlled to be stored in the performance information storage/reproduction means.

[Action/effect]

According to the performance information processing device according to the present invention, since the performance information storage/reproduction means is provided, the performance information can be stored in the performance information storage/reproduction means and can be reproduced. Then, the performance information reproduced from the performance information storage/reproduction means is supplied to the sound source device C to which the sounding body D is connected, as in the case of the conventional performance information processing device described above in FIG. For example, as in the case of the conventional performance information processing device described above in FIG.
From this, it is possible to obtain the flow of musical tones based on the performance information stored in the performance information storage/reproduction means. Furthermore, as in the case of the conventional performance information processing device described above in FIG. It is possible to determine whether or not it exists. Also, at this time, although not mentioned in the case of the conventional performance information processing device described above in FIG. If so, the correction start position of the performance information to be corrected can be determined. Furthermore, the performance information processing device according to the present invention has correction start position setting means, and as described above, the performance information stored in the performance information storage/reproduction means can be determined by the player. Therefore, when the performance information stored in the performance information storage/reproduction means is the performance information to be corrected, the correction start position information representing the correction start position is set in the correction start position setting means. be able to. In addition, since it has performance information storage/reproduction means,
After setting the correction start position information in the correction start position setting means as described above, the performance information stored therein can be reproduced as the first performance information from the performance information storage/reproduction means. Further, at this time, new performance information obtained in real time from the performance information generation source through the actual performance can be generated as the second performance information. Further, since the control means controls the performance information storage/reproduction means as described in () and () above, the performance information is reproduced from the performance information storage/reproduction means as the first performance information, as described above. , and the first performance information is reproduced from the performance information storage/reproduction means while new performance information obtained in real time from the performance information generation source through the actual performance is generated as the second performance information. When the correction start position set in the correction start position setting means is reached, from that point on, new performance information obtained in real time from the performance information source during actual performance is used as the second performance information. The information can be stored in the information storage/reproduction means. Therefore, according to the performance information processing device according to the present invention, it is possible to store performance information as previous performance information in the performance information storage/reproduction means, and also to reproduce the same. As in the case of the conventional performance information processing device described above in FIG. Because you can obtain the flow of musical tones based on the previous performance information stored in the
Whether or not the previous performance information stored in the performance information storage/reproduction means is the performance information to be corrected by the performer, etc., and if the previous performance information is the performance information to be corrected. , the correction start position can be determined. Based on such determination, if the previous performance information stored in the performance information storage/reproduction means is the performance information to be corrected, correction start position information representing the correction start position. can be set by the correction start position setting means. Further, after setting the correction start position information in this way, the previous performance information stored in the performance information storage/reproduction means is reproduced as the performance information to be corrected, and the performance information is updated by actual performance. When the performance information to be corrected reaches the correction start position indicated by the correction start position information set in the correction start position setting means while new performance information obtained in real time from the generation source is generated. Based on the correction start position information, new performance information obtained in real time from a performance information source during actual performance can be stored as performance information after the correction start position of the performance information to be corrected. can. For this reason, if new performance information obtained in real time from a performance information source through actual performance is stored in the performance information storage/reproduction means, the performance information storage/reproduction means will be able to store the corrected information. Corresponding to the performance information up to the correction start position of the previous performance information as the performance information to be corrected, and the performance information after the correction start position of the previous performance information as the performance information to be automatically corrected. Performance information that replaces the previous performance information is stored, including new performance information obtained in real time from a performance information source during actual performance. Therefore, after that, from the performance information storage/reproduction means,
The performance information stored therein can be reproduced as performance information corresponding to the corrected performance information of the previous performance information as the performance information to be corrected. From the above, according to the performance information processing device according to the present invention, new performance information obtained in real time from a performance information generation source during an actual performance is sent to the performance information storage/reproduction means to correct the previous performance information. Since performance information up to the start position that does not need to be corrected is not stored, new performance information obtained in real time from the performance information source during actual performance is redundantly stored in the performance information storage/reproduction means. It can be memorized without any bias. Further, according to the performance information processing apparatus according to the present invention, as described above, the performance information storage/reproduction means stores performance information up to the correction start position of the previous performance information as the performance information to be corrected; New performance information obtained in real time from the performance information source during the actual performance corresponds to the performance information after the correction start position of the previous performance information as the performance information to be automatically corrected. According to
Since the performance information that replaces the previous performance information is stored, the performance information stored in the performance information storage/reproduction means is then used as the performance information to be corrected as the performance information that has been corrected. When the performance information corresponding to the performance information is played back, the playback includes the performance information up to the correction start position of the previous performance information as the performance information to be corrected, and the performance information as the performance information to be corrected. Between the new performance information obtained in real time from the performance information source during the actual performance, which corresponds to the performance information after the correction start position of the previous performance information,
It has characteristics such as not having any unnaturalness.

【Example】

Next, an embodiment of the performance information processing apparatus according to the present invention will be described. The embodiment of the performance information processing device according to the present invention is similar to the conventional performance information processing device described above in FIG. It has a source A, a sequencer B, a sound source device C, and a sounding body D. In the embodiment of the performance information processing apparatus according to the present invention, a sequencer B similar to that described above in FIG.
In the playback mode, the stored data is read from the correction start address _Xo along the flow of musical tones obtained from the sounding body D based on the performance information reproduced from the performance information storage/playback means of the sequencer B. From address point t _{o -2} , which is a little before t o (hereinafter referred to as the correction start address point), a series of key event data is input from keyboard device A to sequencer B by real-time key operations. When the key event data playback progresses to the modified address X _o , the sequencer B is switched from the playback mode to the storage mode, and the sequence from the keyboard device A is transferred to the subsequent addresses X _o , X _o+1 . . . A modified performance is executed in which the key event data of 2 are sequentially stored. In this case, the relationship between the key press/release states represented by the key event data input to sequencer B and the key press/key release states represented by the key event data stored in sequencer B near the correction start address X _{o is} , as described below with reference to FIGS. 3 and 4. In other words, a series of musical tones based on a series of key event data read in playback mode from address _Xo-2 , which is before the modification start address _Xo , to address Xo ₊₁ , which is after the modification address _Xo . But the address time t _o-2 , t _o-1 , t _o , t _o+1
, respectively, and the sound generation/silence state is the third one.
It is assumed that the transition is as shown in Figure B. In this case, the key event data representing the off event (Ba in Figure 3) is read at address time t _o-2 , so the next address time t _o-1
The sound is kept muted until then (Figure 3 Bb). Also, at time t _o-1 , an on event (third
Since the key event data representing (Bc) in Figure 3 is read out, the sound generation state is maintained until the next address time _to (Bd in Figure 3). Furthermore, between address times t _o to t _o+1 ,
Similarly, keep the sound muted (Figure 3 Be). Also, while the above-mentioned playback mode is operating,
While listening to the played musical tone, select any address X in the playback area before the correction start address X _o .
Start key operations starting from , continue key operations in accordance with the flow of the musical tone being played, and then
As shown in Figure 3C, the address point
For t _o-2 to _{t o-1} , enter key event data representing key press/release states that approximately correspond to the sound/silence states (Figure 3 B) represented by the key event data being played. However, after the correction _start address time t _o , after switching the sequencer B to the storage mode, _the key pressed state (Fig.
Suppose that you continue to input key event data that maintains Cf). In such a case, after the correction start address _time ,
The key event data representing the first input off event (Cg in Figure 3) is the correction start address.
Since the sound generation/silence state represented by the key event data when playing again after a modified performance is stored in X _o , the sound generation/silence state represented by the key event data is turned off at the modification start address time _to , as shown in Figure 3D. Event (Figure 3
Dh) is generated, and thereafter the sound changes to the mute state (Di in Figure 3). Also, the sound generation/silence state changes as shown in FIG. 4B, and the key press/key release state shown in FIG. 3(C) changes as shown in FIG. 4C. It shall change as shown in the table below. In this case, when performing a corrected performance, the on event (Fig. 4 Ca) is stored at the correction start address X _o , so when playing again after the corrected performance, the address correction start time t _o and the address time _{t o+ 1} maintains the pronunciation state (Fig. 4 Db). In the embodiment of the performance information processing apparatus according to the present invention, the means includes event management that stores key press/release states represented by key event data input from a keyboard device A as an external device at each time point. table means; pronunciation management table means for storing the sound generation/silence state represented by the key event data output from sequencer B at each time point;
Based on these two table means, at the time of the correction start address, keys whose pressed/released state does not correspond to the sound generation/silence state of the musical tone to be played are searched, and the pressed/released key of the corresponding key is searched. and a modification start processing means for sequentially storing the state at addresses after the modification start address in the memory. Functionally, as shown in FIG. 5, in the playback mode, a series of key event data stored in each address of the memory means 1 is changed to each key event data by the previous performance. Each address of the memory means 1 specified by the address counter 2 is sequentially read out for each event interval period between. In addition, in response to the key event data, the pronunciation management table means 3 (hereinafter referred to as table B) displays the pronunciation information for all keys at each point in time.
Memorize muted state. Furthermore, when performing corrections, the event management table means 4 responds to key event data input from the keyboard device A for each key event.
(hereinafter referred to as table A) stores the key press/release states for all keys at each point in time. Further, the modification start control means 5 controls the content of the address counter 5 to be a modification start address set in advance.
Detect that X _o has been reached. Based on the detection output, the sequencer B operating in the playback mode shifts to the storage mode. Furthermore, at the same time, the correction start processing means 6
searches both tables A and B for all keys, and searches the key event data for keys that correspond to the pressed state on table A and that correspond to the muted state on table B. As key event data representing the key status,
Start correcting each of the key event data of the key corresponding to the key release state on table A and the key that corresponds to the sound generation state on table B as key event data representing the key release state. Addresses after the address are stored sequentially, thereby determining the key press/release state represented by the key event data input from the external device A at the correction start address time t _o (Fig. 3 Cj, 4
Figure Cd) is memorized as a key event that occurred at time t _o (Figure 3 Ek, Figure 4 Ee), and thus the pressed key represented by the key event data input by corrected performance.・Key release state (Fig. 3 Cf,
Figure 4 Cc) and key press/release (sound generation/silence) states represented by key event data output by replaying after corrected performance (Figure 3 El, Figure 4
Ef) and the difference around the correction start point t _o disappears. This can be further elaborated on as follows. That is, as shown in FIG. 6, the sequencer B includes an arithmetic processing unit 7 consisting of a microprocessor (CPU), a memory means 1 interconnected to the microprocessor CPU, and an event management table means 4, that is, a table. A, a sound generation management table means 3, that is, a table B, an address counter 2 as an address specifying means, and a correction start address setting device 2a. Here, each of the table A, the table B, the modification start control means 5, and the modification start processing means 6,
It constitutes a function realizing means realized by executing a program in the arithmetic processing unit 7. Next, its functions will be described with reference to the flowcharts shown in FIGS. 7 and 8. When performing a corrected performance, first, when the arithmetic processing section 7 starts operating (Fig. 7a), it immediately sets the initial value _X0 in the address counter 2 and clears both tables A and B (the 7th Figure b), and
A performance clock as a temporal reference for the musical progression is detected (FIG. 7c), and a performance counter is decremented each time the performance clock is detected (FIG. 7d). In addition, it is determined whether the content of the performance counter has reached "0" (Fig. 7 e), and the performance counter decrement processing (Fig. 7 c to e) is performed until the determination result becomes "YES". continue. The performance counter performs the processing described later (Fig. 7g).
As is clear from the above, since the event interval code representing the elapsed time from the key event specified by the immediately preceding key event data is preset, the process described above (Fig. 7 c to e) Thus, an event interval is formed. If the above-mentioned judgment result (Fig. 7e) becomes "YES", the stored data containing the next key event data is read out from the address specified by the address counter 2 of the memory means 1 (the 7f), the event interval code is preset in the performance counter (FIG. 7g), and then the address counter 2 is incremented to designate the next address in the memory means 1 (FIG. 7h). Next, based on the status of the read key event data, the arithmetic processing unit 6 determines whether the event is an on event or an off event, that is, whether the event is a transition to a sound generation state or a transition to a mute state. (Fig. 7i). If the determination result is an on event, "1" representing the sound generation state is added to the address of table B assigned to the key corresponding to the pitch represented by the key code of the key event data. (Figure 7j). At this time, if the above-mentioned judgment result (Fig. 7i) is an off event, "0" representing the muted state is similarly stored in the address assigned to that key in table B (7th Figure k). Through the above processing (FIG. 7 i to k), the sound generation management table means 3 representing the sound generation/silence state of the key at that point in time is realized. Subsequently, the arithmetic processing unit 7 performs a process (seventh
The state stored in the address of table A assigned to the key related to the above-mentioned process (FIG. 7 i to k), that is, at this point The pressed/released state of the key is determined (FIG. 7l). If the result of the determination is that the key is in a released state, key event data related to that key is output to the subsequent sound source device C (FIG. 7m), and then the process moves to the next step. Further, if the determination result (FIG. 7l) is that the key is pressed, the process moves to the next step without executing any process. Subsequently, the processing unit 7 determines whether key event data is input from the keyboard device A (FIG. 7n). If key event data is entered,
Based on the status of the key event data, it is determined whether it is an on event or an off event (FIG. 7o). If the judgment result is an on event, "1" indicating the key press state is added to the address in table A assigned to the key corresponding to the pitch represented by the key code of the input key event data.
(Figure 7 p). In addition, if the above-mentioned judgment result (Fig. 7 o) is an off event, the address of table A assigned to that key is
"0" representing the key release state is stored (FIG. 7q). Through the above processing (FIG. 7 n to q), the event management table means 4 representing the pressed/released state of the key at that point in time is realized. The above event management process (Fig. 7 n-q)
is executed at the timing of the performance clock after executing a series of processes (c to m in FIG. 7) including the pronunciation management process. However, between the performance clocks, the above-mentioned processes (FIG. 7c-m) are not executed, and the process directly shifts from the process in FIG. 7c to the process in FIG. 7n. For this reason, event management processing (n to n in Figure 7) that responds to randomly input key event data is required.
q) The actual processing speed of subsequent processing increases. Subsequently, the arithmetic processing unit 7 performs the above-mentioned process (seventh
Search table B formed by Figures i to k) and determine the state stored in the address of table B assigned to that key, that is, the sounding/silencing state of that key at that time. (Figure 7r). Then, if the determination result is that the sound is muted,
The key event data related to that key is output to the subsequent sound source device C (FIG. 7s), and then the process moves to the next step. Further, if the above-mentioned determination result (FIG. 7r) is that the sound is being generated, the process moves to the next step without executing any process. If the key event data is not input, the determination result in FIG. 7n becomes "NO" and the subsequent processes (FIG. 7 o to s) are not executed. More specifically, among the series of processes mentioned above,
The process shown in FIG. 7L and the process shown in _FIG . , there is a problem in that for musical tones of the same pitch, the off event that appears first in one of the two performances is realized preferentially, and the second half of the other performance is muted, so this problem has been resolved. This is the process necessary to do so. Subsequently, in the next step, whether or not the address counter ₂ has incremented to the value of the modification start address It is determined whether all stored data has been read out (FIG. 7t). And while the judgment result is "NO",
The series of processes described above (Fig. 6 c to t) are repeatedly executed. Then, each time new stored data is read from the memory means 1 (FIG. 7f), the address counter 2 is incremented and the next address of the memory means 1 is specified until the correction start address X _o is reached. When the judgment result (Fig. 7 t) is "YES"
Therefore, proceed to the next step and use sequencer B.
will transition from playback mode to storage mode. Through the above processing (FIG. 7t), the modification starting means 5 is realized. Subsequently, the arithmetic processing unit 7 shifted to storage mode.
First, clear the performance counter (8th
Figure 8a), table A is searched for the first key (Figure 8b). If the state of that key is in the pressed state, then table B is searched for the same key (Fig. 8c), and if the state of that key is in the sounding state, no execution is performed. Not performed. Furthermore, if the search result of table B (Fig. 8c) is muted, at that point, the address counter 2
The key event data indicating that the key is in the depressed state is stored at the address specified by (Fig. 8f), and the content of the performance counter (the performance The content of the counter (which has become "0" through the process shown in FIG. 8a) is stored as an event interval code representing "0" (FIG. 8e). In this case, the event interval code is not written to the same address as the key event, but is written to the event interval code area at the address immediately before the designated address. Therefore, the address value is
If X _o+1 , the event interval code is written to the address of X _o . Note that, hereinafter, writing the event interval code to the address immediately before the designated address as described above will be referred to as writing the event interval code. Furthermore, if the event interval data and key event are written, address X _o+2 is specified (FIG. 8d). On the other hand, if the search result of table A (FIG. 8b) is that the key is released, then table B is searched for the same key, that is, the first key (Fig. 8b).
Figure g). Then, if the key is in a sounding state,
As mentioned above, the contents of the performance counter (“0”
(event interval code representing the key) and the key event data representing that the key is in the key-release state, are added to the address next to the correction start address.
By storing it in X _o+1 (Fig. 8 h, i),
After updating the memory data of that address X _o+1 , the address counter is incremented, and the next address is
Specify X _o+2 (Figure 8d). Further, if the search result of table B (FIG. 8g) is muted, no execution is performed. Subsequently, the processing unit 7 determines whether the searches of both tables A and B have been performed for all keys (FIG. 8j). Then, until all keys are searched, specify the next key in sequence (Fig. 8 k) and search both tables (Fig. 8 b, c, g),
Corresponds to the key press state on table A and table B
Each of the stored data representing the pressed state of the key corresponding to the muted state above, and the key that corresponds to the released state on table A and the sounding state on table B. The address X _{o+2 following the correction start address X o +} 1 is determined by each of the stored data representing the key release state.
The process of sequentially updating the stored data of (Fig. 8 e,
f, h, i, d) repeatedly, and then
Proceeding to the next step, storage processing of subsequent key event data input from keyboard device A is started. Through the above processing (FIG. 8 a to k), the correction start processing means 6 is realized. Subsequently, when storing subsequent key event data, the arithmetic processing section 7 detects the performance clock (Fig. 8l), and each time the clock arrives,
Increment the performance counter (Fig. 8 m),
Until new key event data is input from keyboard device A (FIG. 8 n), the above-described processes (FIG. 8 l to n) are repeatedly executed, thereby forming an event interval code in the performance counter. do. When new key event data is input, at that point, the key event data is stored at the address of the memory means 1 specified by the address counter 2 (Fig. 8 p), and the previous key event data is stored at the address specified by the address counter 2. By storing the content of the performance counter, that is, the event interval code, in the event interval code area of the address (Fig. 8 o), the stored data at that address is updated, and then the performance counter is cleared (Fig. 8q), prepare for the formation of an event interval code for the next input key event data. Such processing (Fig. 8 l to q) is continued until the address specified by the address counter reaches the final _address It is repeatedly executed while sequentially specifying (FIG. 8 s), and stops at the final address X _nax (FIG. 8 t). The above are examples of the performance information processing device according to the present invention. According to the embodiment of the performance information processing device according to the present invention, although detailed explanation is omitted,

It is clear that the excellent effects described in the section ``Effects'' can be obtained. Note that in the above-described embodiment of the present invention, the key event data from the later performance during the modified performance is the key event data that is input to the sequencer from the keyboard device as an external device, and therefore the later performance is This is an example of real-time performance. However, the present invention is not limited to this, and if the subsequent performance is also an offline performance, key event data output from another sequencer as an external device may be input to sequencer B. In addition, without departing from the spirit of the invention,
Various modifications and changes may be made.
