Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone color transmitter for converting tone color information in performance information output from an existing electronic musical instrument into tone color information conforming to the GM standard and outputting the tone color information.

[0002]

2. Description of the Related Art Conventionally, an electronic musical instrument system in which performance information generated by operating a keyboard or an operation panel, for example, a MIDI message is transmitted to the outside and a musical tone signal is generated by an external device (for example, a sound source module). Has been developed and put into practical use. As one of such MIDI messages, a MIDI message of a program change (hereinafter, referred to as a MIDI message used to instruct a tone change)
It is called "Program Change Message". ).

In this program change message,
The tone number for specifying the tone is included, and the electronic musical instrument etc. that received this program change message
The tone color of the electronic musical instrument is changed to the tone color designated by the tone color number.

By the way, the timbre number often differs depending on the manufacturer and model, and there is no compatibility between existing electronic musical instruments and the like. For example, in one electronic musical instrument, the tone color number "1" is assigned to the tone color of the piano, and in the other electronic musical instrument, the same tone color number is assigned to the tone color of the strings. Therefore, in recent years, the correspondence between timbres and timbre numbers has been unified, and M between manufacturers and models has been changed.
G for the purpose of improving the compatibility of IDI messages
The M (General MIDI) standard is being adopted. In the GM standard, 128 kinds of tone colors are defined, and a unique tone color number is assigned to each defined tone color. Therefore, electronic musical instruments (hereinafter referred to as "GM
Corresponding electronic musical instrument ". ), The program change messages are compatible with each other, and tone color information can be exchanged with each other.

However, timbre information cannot be directly exchanged between an electronic musical instrument having a timbre number peculiar to a model (hereinafter referred to as "non-GM compatible electronic musical instrument") and a GM compatible electronic musical instrument. Therefore, conventionally, the user himself has managed the tone color numbers corresponding to the tone color names and made correspondence between them.

[0006]

In such a method, the relation between the tone color number before conversion and the tone color number after conversion is previously associated with each other, and the conversion is performed by interposing the electronic musical instrument on the transmitting side or the receiving side, or in the middle thereof. It is necessary to store it in the device or the like. In order to store such correspondence, conventionally, an operator has sequentially input a tone color number of an electronic musical instrument not corresponding to GM and a tone color number of an electronic musical instrument corresponding to GM as a pair using an operation panel. Therefore, the operator is required to check the correspondence between the tone color numbers and tone colors output from the electronic musical instrument that is not GM compatible, and
There is a problem in that the above input operation cannot be performed unless the correspondence between the tone color number and tone color of the corresponding electronic musical instrument is well understood.

The present invention has been made in view of such circumstances, and a tone color transmitter capable of setting the tone color number of an electronic musical instrument not compatible with GM and the tone color number of an electronic musical instrument compatible with GM by a simple operation. The purpose is to provide.

[0008]

In order to achieve the above object, the invention described in claim 1 is a receiving means for receiving performance information, a first operating element, and an instruction by the first operating element. If there is, the extracting means for extracting the tone color number in the performance information received by the receiving means, the second operating element, and the second operating element.
Selection means for selecting a specific tone color from a plurality of tone colors, a display means for sequentially displaying the tone color names of the tone colors selected by the selecting means, and extraction by the extracting means. Storage means for storing the selected tone color number and the tone color number corresponding to the tone color selected by the selecting means in association with each other, and storing the tone color number in the performance information received by the receiving means in the storage means. It is characterized in that it further comprises: a converting means for converting according to the established correspondence, and a transmitting means for transmitting the performance information whose tone color number has been converted by the converting means to the outside.

Further, for the same purpose, in the invention described in claim 2, the performance information received by the receiving means is a MIDI message which is not GM compatible, and the performance information transmitted from the transmitting means is GM compatible MIDI. It is characterized by being a message.

[0010]

According to the tone color transmitter of the first aspect, the tone color number included in the input performance information is converted into another tone color number and output. The operation of this tone color transmitter is roughly divided into an operation for associating the tone color pair to be converted and an operation for converting the tone color number in the received performance information according to the correspondence relation set above and transmitting it. It

That is, in order to associate the tone color pairs to be converted, the performer first operates the first operating element to instruct that the tone color number in the performance information received by the receiving means should be extracted. . In this state, when a tone color selection operation is performed with an external device connected to the receiving means, for example, an electronic musical instrument, performance information including the tone color number of the selected tone color is input via the receiving means. Tone number is extracted from. This extracted tone color number becomes the converted tone color number.

Next, the performer operates the second operator to instruct to start setting the tone color number corresponding to the converted tone color number. When a tone color is selected using the selection means while the second operator is being operated, the selected tone color name is displayed on the display means. Therefore, the performer operates the selecting means until the desired tone color name is displayed, and when the operation of the second operator is stopped at the time when the desired tone color name is displayed, it is displayed on the display means at that time. The designated tone color number is confirmed as the converted tone color number. When the converted tone color number and the converted tone color number are determined in this way, these are stored in the storage means as a pair. By repeating the above operation, a plurality of pairs of converted tone color numbers and converted tone color numbers can be stored in the storage means.

When the correspondence of the tone color pairs to be converted is completed by the above operation, the performance information can be transferred with the tone color number converting operation. That is, if the performance information received by the receiving means includes a timbre number, that timbre number is regarded as the converted timbre number, and the matching timbre number stored in the storage means is selected. look for. When a match is found, the tone color number paired with the converted tone color number is taken out and set in the tone color number portion of the received performance information. The performance information created in this way is transmitted to the outside via the transmitting means.

In the tone color transmitter according to the second aspect, the MIDI message which is not GM compatible is received by the receiving means, is converted into a GM compatible message and is transmitted by the transmitting means. Therefore, for example, by interposing a main tone color transmitter between an electronic musical instrument not compatible with GM and an electronic musical instrument compatible with GM, the performance information generated by the electronic musical instrument not compatible with GM is transferred to the electronic musical instrument compatible with GM via the main tone color transmitter. By sending it to
An electronic musical instrument that is not GM compatible can be used like an electronic musical instrument that is GM compatible.

The panel interface circuit 13 controls transmission / reception of data between the operation panel 14 and the CPU 10. That is, the panel interface circuit 13 sends a scan signal to the operation panel 14, and inputs a signal indicating ON / OFF of each switch returned from the operation panel 14 in response to the scan signal. Then, from this signal, panel data in which ON / OFF of each switch is associated with 1 bit is generated and sent to the CPU 10. This panel data is stored in the RAM 12 under the control of the CPU 10,
It is used to determine the presence or absence of panel events (details below).

Further, the panel interface circuit 13 is
The display data sent from the CPU 10 is sent to the operation panel 14. As a result, the display device 143 displays a predetermined number, an alphabetic character, or the like.

The input interface circuit 15 corresponds to a receiving means, receives data sent from the outside, converts it into a signal suitable for a circuit inside the tone color transmitter, and sends it to the system bus 30. . On the outside of the input interface circuit 15, for example,
An electronic musical instrument that is not GM compatible is connected. In this case, the input interface circuit 15 receives MIDI data from an electronic musical instrument not compatible with GM and sends it to the system bus 30.

As shown in FIG. 3, this tone color transmitter is connected to an electronic musical instrument not compatible with GM and an electronic musical instrument compatible with GM via the input interface circuit 15 and the output interface circuit 16 described above.

Next, a method of operating the tone color transmitter configured as described above will be described. First, the operator operates the tone color selection switch of the electronic musical instrument connected to the input interface circuit 15 while pressing the reception switch 140. As a result, a program change message is sent from the electronic musical instrument. This program change message is sent to the RAM 12 under the control of the CPU 10.
It is stored in the receive buffer of. After that, when the operator releases the receiving switch 140, the tone color number in the program change message stored in the receiving buffer is extracted, stored in the converted tone color number buffer, and displayed in the display field 150 of the display 143. To be done.

Next, the operator operates the tone color setting switch 141.
The tone color selection switch 142 is operated with the button pressed.
In the initial state, the tone color number selected at that time (tone color number stored in the tone color number buffer of the RAM 12) is displayed in the display field 151, and the tone color name corresponding to the tone color number is displayed in the display field 152. Has been done. In this state, for example, the up switch 142
When A is pressed, the tone color number stored in the tone color number buffer is incremented and the display field 151 is displayed.
The tone color name corresponding to the tone color number is simultaneously displayed in the display field 152. Hereinafter, similarly,
Each time the up switch 142A is pressed, the timbre number is incremented and displayed in the display field 151,
The display field 152 displays the tone color name corresponding to the incremented tone color number. When the timbre number exceeds the maximum value "127", it is rounded to "0".

Similarly, when the down switch 142B is pressed, the tone color number stored in the tone color number buffer is decremented and displayed in the display field 151.
At the same time, the tone color name corresponding to the tone color number is displayed in the display field 152. Similarly, each time the down switch 142B is pressed, the tone color number is decremented and displayed in the display field 151, and the tone color name corresponding to the decremented tone color number is displayed in the display field 1.
52 is displayed. Then, when the timbre number exceeds the maximum value "0", it is rounded to "127".

When the operator selects a predetermined tone color by the above operation, the operator releases the tone color setting switch 141. As a result, the tone color number displayed in the display field 151 is fixed as the converted tone color number. This converted timbre number is
The converted tone color numbers are stored in the tone color conversion table in pairs with the converted tone color numbers stored in the converted tone color number buffer.

From the operator's point of view, the above operation is as follows. That is, the operator selects the tone color to be changed by pressing the switch corresponding to the tone color name imprinted on the operation panel of the electronic musical instrument on the transmission side. For example, press the switch engraved with the trumpet. By this operation, the tone color number assigned to the trumpet in the electronic musical instrument on the transmission side is displayed in the display field 150 of the operation panel 14, but the operator can change the tone color number regardless of the displayed tone color number. It means that the tones that should be recognized are recognized.

In this state, while looking at the display field 152, the tone color selection switch 14 is pushed while pushing the tone color setting switch 141 until the tone color name "trumpet" is displayed.
Operate 2. Then, the tone color setting switch 141 is released when the tone color name of the trumpet is displayed. At this time, the display field 151 displays the tone color number of the trumpet in the GM-compatible electronic musical instrument, which the operator can ignore. That is, the operator can set the correspondence between the converted tone color number and the converted tone color number only by referring to the tone color name without paying attention to the tone color number of the electronic musical instrument of the transmitting side or the tone color number of the receiving side. You will be able to

Next, the operation of the tone color transmitter of the present invention for realizing the processing corresponding to the above operation will be described.
This will be described in detail with reference to the flowcharts shown in FIGS.

FIG. 4 is a flow chart showing the main routine of the tone color transmitter of the present invention, which is started by turning on the power. When the power is turned on, first, initialization processing is performed (step S10). This initialization process is
In addition to setting the internal state of the CPU 10 to the initial state, R
This is a process of setting initial values in registers, counters, flags, etc. defined in the AM 12.

When this initialization process is completed, a switch event process is then performed (step S11). In this switch event process, a process corresponding to the switch operation of the operation panel 14 is performed. Next, the reception process is performed (step S12). In this receiving process, the process for the MIDI data input from the input interface circuit 15 is performed. Then, a transmission process is performed (step S13). In this transmission process, the received MIDI
A process of converting the data into MIDI data compatible with GM and outputting the data to the outside is performed. Next, returning to step S11, the various functions of the tone color transmitter are realized by repeatedly executing steps S11 to S13.

Details of the above switch event processing are shown in FIG.
Is shown in the flowchart. In the switch event process, first, a panel scan is performed (step S
20). That is, the CPU 10 sends a scan command to the panel interface circuit 13. As a result, the panel interface circuit 13 generates panel data as described above and sends it to the CPU 10. CPU10
Stores this panel data (hereinafter referred to as “new panel data”) in a predetermined area of the RAM 12. Next, the panel data that has been read last time and already stored in the RAM 12 (hereinafter referred to as "old panel data") is compared with the new panel data to create a panel event map in which different bits are turned on. The presence / absence of a panel event is determined by referring to this panel event map.

When the panel scan processing is completed, it is then checked whether or not there is a panel event (step S).
21). That is, it is checked if there is more than one bit turned on in the panel event map.
If it is determined that there is no panel event, that is, if there is no bit that is turned on in the panel event map, the switch event processing routine returns and returns to the main routine. . On the other hand, when it is determined that there is a switch event in step S21, it is then checked whether or not the panel event is the event of the reception switch 140 (step S22). This is done by checking to see if the bit in the panel event map corresponding to receive switch 140 is on.

If it is determined that the event is the reception switch 140, a reception flag change process is performed (step S23). In this reception flag change process,
If the event of the reception switch 140 is an on event, the reception flag is set to "1", and if the event is an off event, the reception flag is cleared to "0". After that, the process returns from this switch event processing routine and returns to the main routine.

In step S22, the receiving switch 140
If it is determined that the panel event is not the event, then it is checked whether the panel event is the event of the tone color setting switch 141 (step S24). This is performed by checking whether or not the bit corresponding to the tone color setting switch 141 in the panel event map is turned on.

If it is determined that the event is the tone color setting switch 141 event, then it is checked whether the event is an on event (step S).
25). This is performed by checking whether or not the bit corresponding to the tone color setting switch 141 in the new panel data is turned on. If it is determined that the event is an on event, the tone color setting flag is set to "1" (step S26). RAM1 for tone color setting flag
This flag is provided in No. 2 and stores that the tone color transmitter is set to the tone color selectable state. After that, the process returns from this switch event processing routine and returns to the main routine.

On the other hand, if it is determined in step S25 that the event is not the on event, it is recognized that the event is the off event, and the tone color setting flag is cleared to "0" (step S27). Then, a tone color conversion table is created (step S28). That is, the tone color number stored in the tone color number buffer to be converted and the tone color number stored in the tone color number buffer at that time are stored as a pair in the tone color conversion table. As a result, the converted timbre number is determined as the timbre setting switch 141 is released, and G
The correspondence of the tone color numbers of the electronic musical instrument not compatible with M and the electronic musical instrument compatible with GM is stored in the tone color conversion table.
After that, the process returns from this switch event processing routine and returns to the main routine.

In step S24, the tone color setting switch 1
If it is determined that the event is not the event 41, then it is checked whether the panel event is the event of the tone color selection switch 142 (step S29). this is,
This is done by checking whether the bit corresponding to the up switch 142A or the down switch 142B in the panel event map is turned on.

If it is determined that the event is the tone color selection switch 142, then whether the tone color setting flag is "1", that is, the tone color setting switch 14 is selected.
It is checked whether 1 is being pressed (step S3).
0). If it is determined that the tone color setting flag is not "1", it is recognized that the tone color setting switch 141 is not being pressed, and no processing is performed for the operation of the tone color selection switch 142. Then, the process returns from this switch event processing routine and returns to the main routine.

On the other hand, when it is determined that the tone color setting flag is "1", it is checked whether the event is the event of the up switch 142A (step S31). This is done by checking whether the bit corresponding to the up switch 142A in the new panel data is turned on. If it is determined that the event is the event of the up switch 142A, the tone color number in the tone color number buffer is incremented (step S32). On the other hand, if it is determined that the event is not the up switch 142A event, the down switch 142B event is recognized and the tone color number is decremented (step S33).

Next, the tone color number and tone color name are displayed (step S34). That is, the tone color number stored in the tone color number buffer is sent to the display device 143 and displayed in the display field 151. Further, referring to the standard tone color table, the tone color name corresponding to the tone color number stored in the tone color number buffer is extracted, sent to the display device 143, and displayed in the display field 152. After that, the process returns from this switch event processing routine and returns to the main routine. As a result, the tone color number is incremented (or decremented) every time the tone color selection switch 142 is operated, and the tone color number resulting from the increment (or decrement) and the tone color name corresponding to the tone color number are displayed on the display unit 143. The function is realized.

In the main routine, the receiving process is then carried out (step S12). For details of this receiving process,
This is shown in the flow chart of FIG.

In the receiving process, it is first checked whether or not a MIDI message has been received (step S40).
This is done by the CPU 10 examining the input interface circuit 15. If it is determined that the MIDI message is not received, no process is performed and the process returns from the reception process routine and returns to the main routine. On the other hand, when it is determined that the MIDI message is received, the received MIDI message is read and transferred to the reception buffer of the RAM 12 (step S41). Next, it is checked whether the reception flag is "1", that is, whether the reception switch 140 is being pressed (step S42). If it is determined that the reception flag is not "1", the process returns from this reception processing routine and returns to the main routine. That is, the MIDI message received when the receiving switch 140 is not being pressed is only set in the receiving buffer.

In step S42, the reception flag is "1".
If it is determined that the MIDI message is received while the receiving switch 140 is being pressed, it is checked whether the MIDI message is a program change message (step S43). This is done by examining the status byte of the MIDI message. If it is determined that the message is not the program change message, the process returns from this reception processing routine and returns to the main routine. That is, MIDI messages other than the program change message received while the receiving switch 140 is being pressed are ignored.

When it is determined in step S43 that the message is a program change message, the tone color number in the program change message is stored in the converted tone color number buffer (step S44). The contents of the converted tone color number buffer are stored in the tone color conversion table in pairs with the contents of the tone color number buffer, as described above. Then
The timbre number is displayed (step S44). That is, the contents of the converted tone color number buffer are sent to the display device 143,
It is displayed in the display field 150. As a result, the operator can confirm the tone color number of the program change message sent from the electronic musical instrument that is not GM compatible and is connected to the input interface circuit 15. After that, the process returns from this reception processing routine and returns to the main routine.

In the main routine, the transmission process is then performed. The details of this transmission processing are shown in the flowchart of FIG.

In the transmission process, first, the presence or absence of received data is checked (step S50). This is done by checking if MIDI data is stored in the receive buffer. Then, when it is determined that there is no received data, the process returns from the receiving process routine to the main routine without performing the transmitting process.

On the other hand, when it is determined that there is received data, the contents of the reception buffer are transferred to the transmission buffer (step S51). Then, it is checked whether the transferred MIDI data is a program change message (step S52). This is done by examining the status byte in the MIDI message. If it is determined that the message is a program change message, tone color number conversion is performed (step S
53). That is, the same tone color number as that included in the program change message is searched from the tone color numbers to be converted in the tone color conversion table, and the tone color number corresponding to the found tone color number to be converted is extracted. Then, this converted timbre number is embedded in the timbre number part of the program change message stored in the transmission buffer. As a result, a program change message whose tone color number is converted so as to correspond to the GM compatible electronic musical instrument is formed in the transmission buffer.

Then, a transmission process is performed (step S).
54). That is, the CPU 10 uses the MID in the transmission buffer.
The I message is sent to the output interface circuit 16. As a result, the output interface circuit 16 sends a GM compatible MIDI message to an external device. If it is determined in step S52 that the message is not a program change message, step S53 is skipped. Therefore, MIDI messages other than the program change message are transmitted to the outside without being changed.

As described above, according to this embodiment,
The tone color number included in the input MIDI data of the non-GM compatible electronic musical instrument is converted into a tone color number that can be handled by the GM compatible electronic musical instrument and is output.

That is, in order to associate the tone color pairs to be converted, the performer first pushes the reception switch 140. In this state, when a tone color selection operation is performed with an electronic musical instrument that is not GM compatible and is connected to the input interface circuit 15, a MIDI message including the tone color number of the selected tone color is input via the input interface circuit 15, The tone color number is extracted from this MIDI message. This extracted tone color number becomes the converted tone color number.

Next, the performer selects the tone color setting switch 141.
Press. When a tone color is selected using the tone color selection switch 142 while the tone color setting switch 141 is pressed, the selected tone color name is displayed on the display unit 143. Therefore, when the performer operates the tone color selection switch 142 until the desired tone color name is displayed, and releases the tone color setting switch 141 at the time when the desired tone color name is displayed, it is displayed on the display 143 at that time. The designated tone color number is confirmed as the converted tone color number. When the converted tone color number and the converted tone color number are determined in this manner, these are stored in the tone color conversion table as a pair. By repeating the above operation, a plurality of pairs of converted tone color numbers and converted tone color numbers can be stored in the tone color conversion table.

As described above, the player can associate the tone color of the electronic musical instrument not compatible with GM with the tone color of the electronic musical instrument compatible with GM by referring to the tone color name without paying attention to the tone color number. As a result, even a beginner can easily perform the above-mentioned association in a short time.

When the correspondence of the tone color pairs to be converted is completed by the above operation, the MIDI with the tone color number conversion operation is performed.
It becomes possible to transfer messages. That is, when the MIDI message received by the input interface circuit 15 includes the tone color number, the tone color number is regarded as the converted tone color number, and the tone color number stored in the tone color conversion table is matched. Find what to do. When a match is found, the tone color number paired with the converted tone color number is taken out and set in the tone color number part of the received MIDI message. M created in this way
The IDI message is transmitted to the outside via the output interface circuit 16 and supplied to the GM compatible electronic musical instrument.

In the above embodiment, as the electronic musical instrument connected to the input interface circuit 15, an electronic musical instrument which is not GM compatible but has a function of outputting MIDI data is used. The same applies to electronic musical instruments that output information. In this case, the data format may be converted into GM compatible MIDI data together with the tone color number included in the message input to the reception buffer.
