Electronic musical instrument main body device and electronic musical instrument system

An electronic musical instrument system comprising:

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

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 first kind of physical connection terminals to which a first playing operation device is connected, the first playing operation device having a plurality of types;
• a plurality of virtual input ports that is provided for different types of the first playing operation device separately from the first kind of physical connection terminals;
• a connection detecting unit that detects connection of the first playing operation device to one of the first kind of physical connection terminals;
• an information acquiring unit that, in a case in which it is detected by the connection detecting unit that the first playing operation device is connected to one of the first kind of physical connection terminals, acquires an information relating to the first playing operation device from the first playing operation device being connected;
• a port assigning unit that assigns one of the virtual input ports of a type corresponding to the information relating to the first playing operation device acquired by the information acquiring unit to the first playing operation device of which the connection with the one of the first kind of physical 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 a first playing information acquired from the first playing operation device connected to the corresponding one of the first kind of physical connection terminals,
• wherein the information acquiring unit, in a case in which it is detected by the connection detecting unit that the first playing operation device is connected to one of the first kind of physical connection terminals, acquires an individual information that is individually assigned to the first playing operation device from the first playing operation device being connected,
• wherein the electronic musical instrument main body device further comprises:
• a port assignment storing unit that stores an identification information used for identifying one of the virtual input ports assigned to the first playing operation device represented by the 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 first playing operation device acquired by the information acquiring unit in a case in which it is detected by the connection detecting unit that the first playing operation device is connected to one of the first kind of physical 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 first playing operation device of which connection with one of the first kind of physical connection terminals is detected by the connection detecting unit, the port assigning unit assigns the corresponding one of the virtual input ports identified by the identification information to the first playing operation device.
