Operation Next, the operation of the first embodiment of the present invention, in particular, the operation of the CPU 4 as the musical tone control means will be described with reference to FIGS. 3 and 4.

FIG. 3 is a flowchart of a data write process from an infrared detection circuit for taking in tone control data as music characteristic control information from an infrared detection circuit for operating the CPU 4 into a register. The data detected from the infrared detection circuit 10 is imported, and the CP
Write to register A in U4. Next, at step 3-2, whether the data value written to the register A is larger than 7F,
That is, it is determined whether the data value is a command (command) or data (numerical value). If YES, the data value is a command (various commands such as tone switching, breath, bend, lip, etc.). The data value of register A is RCOM
It is determined whether it is equal to AD, that is, a command by infrared rays. If YES, it returns to the main flow as it is because it is the same command as the previous command. If the judgment is NO, it means that a new infrared command different from the previous command has been input, so the command flag is set to 1 in step 3-4, and the command flag is set in step 3-5 for the next comparison judgment. Then, the data value of the register A written into the register A is transferred to the RCOMAD register of the infrared command, and the process returns to the main flow.

If A> 7F is NO in step 3-2, the content written in the A register is not a command but numerical data, so in step 3-6, whether or not the command flag is set to 1 If YES, it means that the command type is to be determined and data processing should be performed. In step 3-7, it is determined whether or not the infrared command is a tone command. And when YES, it is a case where the infrared ray corresponding to the tone color switching information for changing the tone color is received by the infrared ray detection circuit 10,
In the next step 3-8, the data for tone change previously written in the register A and the infrared command RCOMAD
In this case, the timbre command is output to the tone generation circuit 7 for timbre switching as timbre control data. In step 3-9, the command flag is output to clarify that the operation according to the timbre command has been completed. Is reset to 0 and the process returns to the main flow.

If NO in step 3-7, since the infrared command is not a tone command, it is determined in step 3-10 whether the infrared command is a breath command.
If S, the data of the register A is stored in the RBRETH buffer for storing external infrared breath information in step 3-11. Similarly, in step 3-9, the command flag is reset to 0 and the process returns to the main flow. If NO in step 3-10, in step 3-12, other commands, such as a bend command and a lip command, are determined, and data store processing of the register A of each buffer is performed. In step 3-9, a command flag is set. Reset to 0 and return to the main flow.

If NO in step 3-6, that is, if the command flag is not 1, there is no change in the command. In step 3-13, it is determined whether the data of the register A previously written is the same as the infrared data. If YES, it returns to the main flow as it is because the same command and the same data. If NO, the data of the A register is stored in the infrared data register in step 3-14. In step 3-15, a process for changing data in the same command is performed, and the process returns to the main flow.

FIG. 4 is a flow for causing a timer interrupt to the main flow, and is a flowchart of processing of breath information from the breath sensor 1, that is, processing of breath information when a blow is performed by a player. First, in step 4-1, digital data from the A / D converter 3 is fetched and stored in the A register in the CPU 4. Next, at step 4-2, the data value of the A register, that is, the detected data value from the breath sensor 1 is equal to or greater than the infrared data value as the tone characteristic control information transmitted by operating the foot controller FC of the infrared radiation device 9. It is determined whether or not there is, and if YES, it is determined in step 4-3 whether or not the data value of the A register is equal to the data value detected by the breath sensor 1 due to the player's blowing. In the case of YES, since the breath information is the same as that previously stored, there is no need to change the volume or tone of the musical tone, and the process directly returns to the main flow. The data is entered into the data register of breath information from the breath sensor, and the process proceeds to step 4-5. The data detected by the blowing of the player registered in step 4-4 is used as breath information, that is, the volume of the musical tone as musical tone control data. To change the tone or the sound quality, the signal is sent to the tone generation circuit 7, and the process returns to the main flow.

If NO in step 4-2, that is, if the data value of the register A is the foot controller in the infrared radiation device 9,
If the data value is not equal to or greater than the data value transmitted by the FC, the infrared breath data as external breath information input from the infrared detection circuit 10 in step 4-6 is obtained from the breath sensor 1 by the player's actual blowing. It is determined whether the data value is equal to the data value of the breath information. If YES, the process directly returns to the main flow. If NO, the infrared data input from the infrared detection circuit 10 in step 4-7 is played. Into the register INBRETH for storing the breath information data obtained by the player.
Next, in step 4-5, the data transferred to the register INBRETH, that is, the infrared breath data as external breath information is generated as current breath information, that is, musical tone control data, by changing the volume and tone of the musical sound. For this purpose, the flow is sent to the tone generating circuit 7 and the flow returns to the main flow, thereby ending this flow.
