Electronic musical instrument main body device and electronic musical instrument system

An electronic musical instrument system comprising:

• a playing operation device that generates playing information;
• and
• an electronic musical instrument main body device to which the playing operation device is connected,
• wherein the playing operation device includes a playing operation device information storing unit that stores information relating to the playing operation device, and
• wherein the electronic musical instrument main body device includes:
• a plurality of physical connection terminals to which the playing operation device is connected;
• a tone assigning unit that provides a virtual input port separately from the connection terminals for each type of the playing operation device and, to each input port, assigns a tone of a sound generated on the basis of playing information input to the input port;
• a connection detecting unit that detects that the playing operation device is connected to one of the connection terminals;
• an information acquiring unit that, in a case in which it is detected by the connection detecting unit that the playing operation device is connected to one of the connection terminals, acquires information relating to the playing operation device stored in the playing operation device information storing unit of the playing operation device being connected;
• a port assigning unit that assigns the virtual input port of a type corresponding to the information relating to the playing operation device acquired by the information acquiring unit to the playing operation device of which the connection with the one of the connection terminals is detected by the connection detecting unit;
• and
• a musical sound generating unit that generates a musical sound signal of a tone assigned by the tone assigning unit to the virtual input port assigned to the playing operation device by the port assigning unit on the basis of the playing information acquired from the playing operation device connected to the connection terminal.

An electronic musical instrument main body device configuring an electronic musical instrument system by being connected to a playing operation device generating playing information, the electronic musical instrument main body device comprising:

• a plurality of physical connection terminals to which the playing operation device is connected;
• a virtual input port that is provided for each type of playing operation device separately from the connection terminals;
• a connection detecting unit that detects connection of the playing operation device to one of the connection terminals;
• an information acquiring unit that, in a case in which it is detected by the connection detecting unit that the playing operation device is connected to one of the connection terminals, acquires information relating to the playing operation device from the playing operation device being connected;
• a port assigning unit that assigns the virtual input port of a type corresponding to the information relating to the playing operation device acquired by the information acquiring unit to the playing operation device of which the connection with the one of the connection terminals is detected by the connection detecting unit;
• and
• a musical sound generating unit that generates a musical sound signal on the basis of playing information acquired from the playing operation device connected to the connection terminal,
• wherein the information acquiring unit, in a case in which it is detected by the connection detecting unit that the playing operation device is connected to one of the connection terminals, acquires individual information that is individually assigned to the playing operation device from the playing operation device being connected,
• wherein the electronic musical instrument main body device further comprises:
• a port assignment storing unit that stores identification information used for identifying the virtual input port assigned to the playing operation device represented by individual information by the port assigning unit in association with the individual information acquired by the information acquiring unit and is able to maintain the identification information also during a period in which power is off;
• and
• a storage determining unit that determines whether the identification information is stored in the port assignment storing unit in association with the individual information of the playing operation device acquired by the information acquiring unit in a case in which it is detected by the connection detecting unit that the playing operation device is connected to one of the connection terminals, and
• wherein, in a case in which it is determined by the storage determining unit that the identification information is stored in the port assignment storing unit in association with the individual information of the playing operation device of which connection with one of the connection terminals is detected by the connection detecting unit, the port assigning unit assigns the virtual input port identified by the identification information to the playing operation device.
