Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument parameter setting device for setting parameters for processing a signal according to a performance operation. 2. Description of the Related Art Conventionally, a plurality of signal input sections for connecting a plurality of electronic pads have been provided, and a signal corresponding to a performance operation of a plurality of electronic pads connected to the plurality of signal input sections has been provided. 2. Description of the Related Art An electronic musical instrument parameter setting device that sets parameters for processing is known. In such a parameter setting device, since various electronic pads are connected to each of the plurality of signal input units, various parameters according to the characteristics of the various connected electronic pads are set. Here, when a performance operation using the electronic pad is performed, a signal corresponding to the performance operation is input to a signal input unit to which the electronic pad is connected. The input signal is processed in accordance with various preset parameters and MIDI (M
usical Instrument Digital
The signal is output to an external sound source constituting the electronic musical instrument as an interface signal. In the above-described parameter setting device, different parameters can be set for each of a plurality of signal input units, but the same parameters are set for a plurality of signal input units. If the user wants to make settings, it is necessary to make settings as many as the number of signal input units × the number of parameters. Therefore, there is a problem that setting parameters is troublesome and lacks operability. [0004] In view of the above circumstances, it is an object of the present invention to provide an electronic musical instrument parameter setting device with improved operability. A parameter setting device for an electronic musical instrument according to the present invention which achieves the above object has a plurality of signal input sections for inputting signals corresponding to a performance operation, and an input from the signal input section. A parameter setting unit that sets a parameter for processing the processed signal in association with the signal input unit, and a signal input unit that sets a signal input from the signal input unit by the parameter setting unit. A performance information generating unit that generates performance information by processing according to the parameters associated with the parameter setting unit.
Instead of directly setting the parameter in association with the signal input unit, it is possible to set information for designating another signal input unit, and the performance information generating unit includes the signal input unit. In processing the signal input from the above, if the information that specifies the other signal input section is set by the parameter setting section in association with the signal input section, the parameter setting section corresponds to the other signal input section. It is characterized in that processing is performed in accordance with the set parameters. In the electronic musical instrument parameter setting device of the present invention, when processing a signal input from a certain signal input unit, information for designating another signal input unit is set in association with the signal input unit. In this case, since the processing is performed according to the parameters set in association with the other signal input units, a link function of matching a parameter in one signal input unit with a parameter in another signal input unit is provided. It will be. With such a link function, a setting parameter in a certain signal input unit is the same as a setting parameter in another signal input unit, and when a setting parameter in another signal input unit is changed, a setting parameter in a certain signal input unit is also changed. Will be changed. Therefore, for example, when it is desired to set the same parameters for a plurality of signal input units, changing the setting parameters in one signal input unit can change the setting parameters in all the remaining signal input units. It is not necessary to perform the setting of the number of signal input units × the number of parameters as in the above case, and labor is reduced and operability is improved.

e is set to the same Pad-A as the input 1 (see the display unit 21). The parameter PAD-Type will be described with reference to FIG. The electronic pads connected to the signal input unit include:
Each company has various types, and the input signals are various. That is, the relationship between the striking force and the output level differs depending on the electronic pad. Therefore, the sensitivity (Sense) and the curve (C
urve) and a threshold value (Threshold), the same level of output can be obtained by hitting with the same strength even if the electronic pad is different. These three parameters are set in advance in accordance with the PAD-type as R
It is stored in the OM 30 and can be set by the user simply selecting one of these sets. Here, the parameter sensitivity is the slope of a curve representing a function of the level of the input signal and the velocity value output as the musical tone generation instruction data. The curve is a straight line or an upwardly convex curve. , And the threshold value is the lowest level of the input signal set to prevent malfunction due to noise. Similarly, the note number can be set in the range of 0 to 127 by pressing the note number switch 26 and then pressing the down switch 22 / up switch 23. Note numbers are not linked. To end the edit mode, the user presses the edit switch 27. Then, the set parameters are stored in the RAM 40, and thereafter, the mode shifts from the edit mode to the performance mode. To cancel the edit mode in the middle, press the edit / write / cancel switch 27 for one second or more. As a result, the edit mode is canceled and the performance mode is set. FIG. 4 is an example of each parameter set in the above-mentioned edit mode. FIG. 5 shows the result of the link in FIG. For the inputs 1 to 6, the parameter "MIDI-ch" and the parameter "PAD-type
e "and the parameter" NOTE No. "are stored. Input 1 is MIDI channel 5
The channel and PAD-type are set to Pad-A. The input 4 has five channels because the MIDI channel is linked to the input 1. The input 5 also has 5 channels since the MIDI channel is linked to the input 1. FIG. 6 shows input 1 in the setting of FIG.

In this processing routine, a multitask operation is performed, and is started when a signal is input for each signal input unit. First, in step S1, PAD-T
It is determined whether or not the type is linked. PAD
If it is determined that Type is linked, the process proceeds to step S2. In step S2, the link destination PA
D-Type data (parameters Sense, Cu
rve, Threshold) are set in the buffer, and the flow advances to step S4. On the other hand, if it is determined in step S1 that the PAD-Type is not linked, the process proceeds to step S3. In step S3, P
Each data of AD-Type is set in the buffer, and the process proceeds to step S4. In step S4, it is determined whether the value input to the signal input unit is larger than the parameter Threshold. If it is determined that the value input to the signal input unit is smaller than or equal to the parameter Threshold, the process exits this routine. That is, since the input level is equal to or less than the threshold value, it is determined as noise and the performance information is not output. On the other hand, when it is determined that the value input to the signal input unit is larger than the parameter Threshold, the process proceeds to step S5. In step S5, it is determined whether or not the MIDI channel is linked. If it is determined that the MIDI channel is linked, the process proceeds to step S6. In step S6, the data of the MIDI channel at the link destination is set in the buffer, and
Proceed to. On the other hand, if it is determined that the MIDI channel is not linked, the process proceeds to step S7. In step S7, the MIDI channel data is set in the buffer, and the flow advances to step S8. In step S8, each data is read from the buffer to create new data. In detail, based on the value of each buffer, a note number (NOTE No.) is obtained from a MIDI channel, velocity (refer to parameters Sense and Curve), and a table.
Create a note-on signal. Next, in step S9, the created note-on signal is output, and the routine exits.
