In �setting� field, performance terminals (facilitator and piano (1 to 5)) are displayed. A pull-down menu for selecting presence/absence of each performance terminal and radio buttons for assigning performance parts are displayed. According to the presence/absence of each student, the selection of a presence/absence menu is inputted. When song title data is selected, a controller (1) reads a part assignment table of the song data and assigns a performance part to each performance terminal for which presence is selected. A performance part can be manually assigned to each performance terminal.
TECHNICAL FIELD The present invention relates to an ensemble system that enables even a performer unfamiliar with operation of musical instrument to easily participate in an ensemble performance, and more particularly, to an ensemble system with which performance parts can easily and flexibly be assigned to a facilitator and participants.
DISCLOSURE OF THE INVENTION To achieve the above object, an ensemble system of this invention comprises a plurality of performance terminals each having at least one performance operator unit used for performance operation, at least one tone generator, and a controller connected to the plurality of performance terminals and the at least one tone generator and adapted to control each of the performance terminals, wherein the controller includes storage means adapted to store pieces of music data for performance each including a plurality of performance parts, and an assignment list including identification information indicating which performance part should be assigned to which performance terminal, operation means used for designating at least one performance terminal participating in an ensemble and at least one performance terminal not participating in the ensemble, and used for selecting music data for performance to be played in the ensemble, performance part assignment means adapted to assign performance parts to respective performance terminals in accordance with the assignment list when music data for performance is selected by the operation means, the performance part assignment means being adapted to change assignment of at least one performance part from the performance terminal not participating in the ensemble to the performance terminal participating in the ensemble, and performance control means adapted to read out the performance part assigned to each of the performance terminals in accordance with a way in which the performance operator unit of each of the performance terminals is operated, and output data representing the read-out performance part to the tone generator.
FIG. 11 is a view for explaining a beat deviation relative to a performance terminal �Facilitator�;
Next, an explanation will be given of a user interface shown on the display unit 16. Referring to FIG. 6, a main operation window is displayed on the display unit 16. In a text field in an upper part of this window, the name of music data for being performed, which is selected by the user, is shown. In a �Setting� field, the performance terminals (Facilitator and Pianos 1 to 5) are indicated. For each of the performance terminals, a pull-down menu for selection of presence/absence and radio buttons for performance part assignment are shown. The performance terminals (Facilitator and Piano 1 to 5) are associated with MIDI ports of the MIDI interface box 3. It should be noted that, as shown in FIG. 7, the facilitator can manually select MIDI ports associated with the performance terminals (Facilitator and Pianos 1 to 5).
In the case that the performance part assignment is automatically implemented based on the table shown in FIG. 5, if there is a performance terminal for which the �absence� is selected on the presence/absence pull-down menu, a performance part scheduled to be assigned to the absent performance terminal is assigned to the performance terminal �Facilitator�. In that case, the performance part for the �absent� performance terminal may be assigned to another performance terminal, instead of a performance part scheduled to be assigned to the other performance terminal and close in tone color or role to the performance part for the absent performance terminal (for example, the part scheduled to be assigned to the absent terminal is a drums part, and the part scheduled to be assigned to the other terminal is a base part, string instrument part, or the like). The relation between interrelated performance parts may be specified in advance in the table.
Referring to FIG. 8, a field for indicating a beat deviation relative to the beat of the performance terminal �Facilitator� is displayed on the right side of the middle of the window. In this field, a plurality of (for example, five) vertical lines are shown, and lateral lines are shown such as to correspond to respective ones of the performance terminals. In addition, there are shown circular marks respectively corresponding to these performance terminals. Each circular mark indicates a deviation relative to the performance terminal �Facilitator�.
FIG. 11 is a view for explaining a beat deviation relative to the performance terminal �Facilitator�. As shown in FIG. 10, the circular mark corresponding to the performance terminal �Facilitator� is fixedly shown on the center line among the vertical lines, and each of the circular marks respectively corresponding to user's performance terminals (for example, the circular mark corresponding to �Piano 1�) is moved to the left and the right according to the beat deviation relative to the performance terminal �Facilitator�. For example, when the key depression is lag behind the key depression on the performance terminal �Facilitator� by one bar (four beats in this example), the circular mark is moved leftward by one vertical line as shown in FIG. 10. If there is a delay of one-half bar (two beats), the circular mark is moved leftward from the center vertical line by a distance equal to half an interline distance. On the other hand, if the key depression leads the key depression on the performance terminal �Facilitator�, the circular mark is moved rightward. In FIG. 11, there are displayed two lines with respect to the center line on each side, left and right, and therefore, a beat deviation of up to two bars can be displayed. If there occurs a beat deviation of more than two bars, the icon is changed (into, for example, a rectangular icon) at the left or right end of the line. As a result, each user can easily recognize a deviation of performance (beat) from that of the facilitator. Although the shift of one line represents a deviation of one bar in the above example, the shift of one line may represent a deviation of one-half bar or two bars, for example.
As described above, each user can implement the performance by performing simple operations such as depressing the keyboard with a finger, and an ensemble performance can be carried out by the users, while enjoying themselves, by making operations in such a way as to reduce a deviation of performance (beat) displayed on the display unit 16 from that of the performance terminal �Facilitator�.
The following operation can be carried out as a modification by the ensemble system. FIG. 12A is a view for explaining a model performance mode. As shown in FIG. 12A, �model� icons are displayed on some part (for example, on a left part) of the main operation window in FIG. 6. When any of the �model� icons is depressed by the facilitator, an ordinary mode is changed over to the model performance mode. FIG. 12B is a part of a screen on which a performance terminal for performing a model performance is selected. As shown in FIG. 12B, in the model performance mode, radio buttons for performance terminals 2 other than that for the facilitator are displayed. The facilitator selects the radio button corresponding to one of the performance terminals (Piano 1 to Piano 5) with which the facilitator performs a model performance. In the model performance mode, a performance operation on the selected performance terminal 2 is carried out at the performance terminal �Facilitator�, and music sound is reproduced from the selected performance terminal 2 in accordance with the operation at the performance terminal �Facilitator�. For example, in a case where the Piano 1 is selected as shown in FIG. 12B, when the keyboard of the performance terminal �Facilitator� is depressed, the controller 1 transmits sounding data to the performance terminal �Piano 1� in accordance with a note message input to the controller. The sounding data to be transmitted is the performance part assigned to the performance terminal �Piano 1�. In the performance terminal �Piano 1�, music sound is sounded based on the received sounding data. As a result, the model performance by the facilitator can be heard by each user by his/her performance terminal at hand. In the above example, the case where a single performance terminal is selected using a radio button and the model performance is carried out. Alternatively, the model performance can be carried out after a plurality of performance terminals are selected simultaneously. All the performance terminals can be selected.
The operation of the ensemble system in the model performance mode is described in detail below. FIG. 13 is a flowchart showing the operation of the controller 1 in the model performance mode. When any of the �model� icons is depressed by the facilitator, the start of the operation is triggered.
First, it is determined whether or not a Note On message is received (s11). This determination is repeated until a Note On message is received. If a Note On message is received, whether or not the Note On message has been transmitted from the performance terminal for use by the facilitator is determined (s12). If the received Note On message has not been transmitted from the performance terminal for the facilitator, the flow is repeated from the determination on reception (s12 to s11). On the other hand, if the received Note On message has been transmitted from the performance terminal for the facilitator, music data for the performance part assigned to a designated performance terminal is sequenced (the tone pitch and length of each sound, etc. are determined) (s13). As described above, at least one performance terminal to be designated is selected by the facilitator. It is assumed that the Piano 1 is selected as the designated performance terminal in the initial setting when any of the �model� icons is depressed by the facilitator. Alternatively, a performance terminal corresponding to a �model� icon in FIG. 12A which has been depressed can be selected as the designated performance terminal. Subsequently, sounding data is transmitted to the designated performance terminal (s14).
INDUSTRIAL APPLICABILITY With this invention, since automatic assignment of performance parts is achieved by only specifying attendance (presence) and nonattendance (absence) of performance terminals, easy and flexible assignment of performance parts can be carried out between the facilitator and the participants. Since performance parts for performance terminals can manually be changed, the performance parts can be played by performance terminals different from those at the initial setting, and a model can be given by the performance terminal for the facilitator.
