Abstract

This electronic musical instrument main body device comprises an information acquisition unit and a port assignment unit. The information acquisition unit acquires, from a playing operation device connected to one connection terminal, information related to the playing operation device. The port assignment unit assigns, to the playing operation device, a virtual input port of a type corresponding to the information related to the playing operation device and acquired by the information acquisition unit.

First claim

The invention claimed is:

1. 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 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 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 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.

2. The electronic musical instrument main body device according to claim 1 , further comprising:
a tone identification information storing unit that stores, for each of the virtual input ports, tone identification information used for identifying a tone assigned by the tone assigning unit to the corresponding one of the input ports and is able to maintain the tone identification information also during a period in which power is off;
a tone change accepting unit that accepts a change of the tone assigned by the tone assigning unit to the corresponding one of the input ports from a user; and
a tone identification information rewriting unit that rewrites the tone identification information stored in the tone identification information storing unit for the corresponding one of the input ports, for which the change is performed, with tone identification information for identifying a tone after change in a case in which the change of the tone is accepted by the tone change accepting unit.

3. The electronic musical instrument main body device according to claim 2 ,
wherein, 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, the information acquiring unit acquires an individual information that is individually assigned to the first playing operation device from the first playing operation device being connected,
the electronic musical instrument main body device further comprising:
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,
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.

4. The electronic musical instrument main body device according to claim 3 ,
wherein, 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, the information acquiring unit acquires parameters relating to an operation of the first playing operation device from the first playing operation device being connected,
wherein the port assignment storing unit stores parameters relating to an operation of the first playing operation device represented by the individual information in association with the individual information acquired by the information acquiring unit and is able to maintain the parameters also during a period in which power is off,
wherein the storage determining 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, determines whether the parameters are 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,
the electronic musical instrument main body device further comprising:
a change accepting unit that accepts a change of the parameters stored in the port assignment storing unit from a user;
a first transmission unit that, in a case in which the change of the parameters is accepted by the change accepting unit, transmits the parameters after change to the first playing operation device represented by the individual information with which the changed parameters are associated; and
a second transmission unit that, in a case in which it is determined by the storage determining unit that the parameters are 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, transmits the parameters stored in the port assignment storing unit to the first playing operation device represented by the individual information.

5. The electronic musical instrument main body device according to claim 1 ,
wherein, 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, the information acquiring unit acquires an individual information that is individually assigned to the first playing operation device from the first playing operation device being connected,
the electronic musical instrument main body device further comprising:
a port assignment storing unit that stores an identification informat
