Description

  The present invention relates to a parameter setting device and a parameter setting program for setting parameters related to generated musical sounds.

  2. Description of the Related Art Conventionally, parameters have been set using a display with a touch panel as means for easily setting various parameters in an electronic device. For example, when the volume is set to the volume of each part in the musical sound generator, for example, when the volume of each part is set using a display with a touch panel, a slider type as shown in FIG. A control is displayed. This slider-type controller is displayed for each of four parts, for example, # 1 part, # 2 part, # 3 part, and # 4 part, and operation parameters 131a, 132a, 133a, and 134a for setting parameters are set. It consists of parameter value display parts 131b, 132b, 133b, 134b for displaying values. For example, when changing the volume of the # 1 part, the position touched by the corresponding touch panel is detected by touching the position of the volume to be set on the operation portion 131a with a finger, and the volume of the # 1 part is set. The volume is changed to the volume corresponding to the position. In this case, the length of the parameter value display portion 131b is changed to the size of the changed parameter value and displayed. Similarly, the parameter values of the parts # 2 to # 4 can be changed.

  In such a parameter setting device using a conventional touch panel, the parameter value is set by touching the touch panel with a finger. For this reason, there is a problem that it is difficult to change a fine parameter value when setting the parameter value.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a parameter setting device and a parameter setting program that can easily change fine parameter values using a touch panel.

  In order to achieve the above object, the parameter setting device and the parameter setting program of the present invention are characterized in that a parameter setting means is provided for finely setting parameter values set on the touch panel. Yes.

According to the present invention, by providing the parameter setting means for finely setting the parameter values set on the touch panel, even if the touch panel is used, the detailed parameter values can be easily changed in units. It becomes like this.
Also, when selecting a parameter to be changed by the parameter setting means, it is necessary to select a parameter assigned to one of the operation parts as a setting target, but it corresponds to the parameter value set at the time of selection. If a position different from the position to be touched is touched, the set parameter value is changed. Therefore, in the present invention, a selection part capable of selecting a parameter to be set is displayed on the display means, and a parameter to be changed by the parameter setting means can be selected as a setting target parameter by touching the selection part. I have to. Thereby, when the parameter to be changed is selected by the parameter setting means, it is possible to prevent the set parameter value from being changed.

  The purpose of easily changing fine parameter values was realized by providing parameter setting means that finely set parameter values set on the touch panel.

FIG. 1 is a block diagram showing a configuration of a musical sound generating apparatus including a parameter setting apparatus according to an embodiment of the present invention.
The musical tone generator 1 shown in FIG. 1 includes a parameter setting device according to the present invention. In such a musical sound generator 1, a CPU (Central Processing Unit) 10 controls the overall operation of the musical sound generator 1. Furthermore, by executing the automatic performance program, the sound generation instruction process and the mute instruction process based on the performance data are executed, and by executing the parameter setting program, the parameter value set for each part can be changed. Yes. Thus, in the musical sound generating device 1, the parameter setting device is realized by executing the parameter setting program. A ROM (Read Only Memory) 11 stores operation software such as an automatic performance program executed by the CPU 10 and a parameter setting program. A RAM (Random Access Memory) 12 stores a work area of the CPU 10 and various data. A storage area is set. By making this ROM 11 a rewritable ROM such as a flash memory, the operation software can be rewritten and the operation software can be easily upgraded.

  The operation element 13 is a panel operation element including a rotary encoder provided on the panel of the musical tone generator 1 and a touch panel provided on the display unit 15. The detection circuit 14 detects an event by scanning a panel operation element or a touch panel, and outputs an event output corresponding to the operation element 13 having the event. The display unit 15 is made of liquid crystal or the like and includes a touch panel. The display circuit 16 is display driving means for displaying various setting screens including a parameter setting screen on the display unit 15 and displaying an operation screen and the like at the time of musical tone generation on the display unit 15. The communication interface (I / F) 20 is an interface for connecting the musical sound generator 1 to a communication network such as a LAN (local area network), the Internet, a telephone line, and the like, and is connected to the external device 21 via the communication network. be able to. Accordingly, various programs and data can be downloaded from the external device 21. The downloaded program and data are stored in the RAM 12 or the like.

  The tone generator circuit 17 generates tone signals in response to tone generator parameter information and a sound generation start instruction from the CPU 10 when generating tone signals that are FM tone generators, waveform memory tone generators, physical model tone generators, and the like. The sound source parameter information is assigned channels, pitch information, envelope parameters, and the like. The musical tone signal generated by the tone generator circuit 17 is supplied to the effect circuit 18 and the set effect is added. The musical sound signal to which the effect is applied by the effect circuit 18 is emitted from the sound system 19. Each unit of the musical tone generator 1 exchanges data with each other via the communication bus 22.

Next, parameter setting in the parameter setting device according to the present invention will be described. Here, an example in which the volume of each part is set as a setting parameter will be described.
When setting the volume of each part, a screen for setting the volume for each part shown in FIG. In this screen, as shown in FIG. 2, the slider-type controls of the four parts # 1, # 2, # 3, and # 4 are simultaneously displayed. This slider-type operation element is composed of operation portions 31c, 32c, 33c, and 34c for setting parameters and parameter value display portions 31d, 32d, 33d, and 34d for displaying set parameter values. For example, when changing the volume of the # 1 part, the position touched by the touch panel provided on the display unit 15 is detected by touching the position of the volume to be set on the operation portion 31c with a finger. The volume of # 1 part is changed to the volume corresponding to the position. In this case, the length of the parameter value display portion 31d is changed to the changed parameter value and displayed. Similarly, the parameter values of the parts # 2 to # 4 can be changed.

  Further, the vicinity of the displayed slider-type operation element for each part is a focus portion 31a, 32a, 33a, 34a for selecting the slider-type operation element for each part, and a character string “#” indicating the part. The surroundings of “1 part”, “# 2 part”, “# 3 part”, and “# 4 part” are also focus portions 31b, 32b, 33b, and 34b for selecting a slider-type controller for each part. A rotary encoder 35 shown in FIG. 2 is one of the operators 13 and is provided on the operation panel.

  Here, a case where the volume of the # 3 part is changed will be described. First, the finger touches the position of the volume to be set on the operation portion 33c. As a result, the position touched by the touch panel provided on the display unit 15 is detected, and the volume of the # 3 part is changed to the volume corresponding to the position. Since the volume setting is performed on the touch panel, it is not a fine value setting but an operation for setting a rough approximate value. However, this operation does not necessarily have to be performed, and can be omitted if it is desired to finely change a value that has already been set. Next, when the focus portion 33a or the focus portion 33b is touched, the focus portions 33a and 33b are highlighted to indicate that the volume parameter of the # 3 part has been selected. Here, when the rotary encoder 35 is operated, the volume parameter of the # 3 part selected according to the operation amount is changed. Since the setting unit of the rotary encoder 35 is a small value, the parameter value can be set in fine units, and the volume of the # 3 part is changed in fine units. When the # 4 part is also selected by simultaneously touching the focus part 34a or the focus part 34b, the volume of the # 3 part and the # 4 part can be simultaneously changed in fine units by operating the rotary encoder 35. it can. The parameter is not limited to the volume, and may be another musical sound parameter. Similarly, the volume of other parts can be changed for each part or a plurality of parts at the same time in fine units.

Next, FIG. 3 shows a flowchart of touch processing in the parameter setting device according to the present invention.
The touch process is activated when a touch on a touch panel provided on the display unit 15 is detected, and it is determined whether or not the touched image is a slider-type controller in step S10. If the detection circuit 14 determines that the touched image by operating the touch panel is a slider-type controller, the process proceeds to step S11. If the detection circuit 14 determines that the touched image is not a slider-type controller, step S11 is performed. Proceed to S14. In step S11, it is determined whether or not the touched portion is a focus portion. In this case, if the detection circuit 14 determines that the touched part is the focus part by operating the touch panel, the process proceeds to step S12. If the touched part is determined not to be the focus part, the process proceeds to step S15. In step S12 and step S13, the touched focus portion is highlighted, and a parameter assigned to the slider-type controller corresponding to the focus portion is assigned to the rotary encoder as a setting target parameter. In step S14, processing corresponding to the touched image is performed. That is, processing such as selection processing and on / off setting is performed in accordance with the soft switch at the touched position. In step S15, since the operation part for setting the parameter is touched, the parameter value is set to a value corresponding to the touched position. Then, the touch process ends when any one of steps S13 to S15 ends.

Next, FIG. 4 shows a flowchart of the rotary encoder process in the parameter setting apparatus according to the present invention.
The rotary encoder process is started when the rotary encoder 35 is operated. In step S20, the operation amount and the parameter to be set are detected. The parameter to be set in this case is determined in step S13 in the touch process shown in FIG. That is, the parameter assigned to the slider-type operation element selected by the focus portion and highlighted on the display unit 15 is set as the parameter to be set. Next, in step S21, the change amount of the parameter to be set detected in step S20 is determined according to the detected operation amount of the rotary encoder 35. In step S22, the parameter value to be set is changed according to the change amount determined in step S21. When the process of step S22 ends, the rotary encoder process ends.

In the above description, the software operator for setting the parameter displayed on the display unit 15 is a slider type operator. However, the present invention is not limited to this, and a touch panel for setting the parameter value is used. Any type of operator may be used as long as it is a soft operator. The parameter is not limited to the sound volume, and may be another musical sound parameter. Furthermore, the focus portion is preferably in the vicinity of the soft operation element as in the embodiment, but may be arranged in any location as long as the soft operation element can be quickly selected. Further, the physical operator for changing the value of the parameter to be set is not limited to the rotary encoder, and any physical operator that can change the parameter value may be used. Furthermore, a plurality of parameters may be set using a common operator, or may be set using different operators for each setting target parameter.
When the parameter setting program is not stored in the ROM 11, an HD (hard disk) or CD-ROM drive is provided to store the parameter setting program or data in the HD or CD-ROM, and these are stored in the RAM 12. The CPU 10 performs the same operation as when the parameter setting program or data is stored in the ROM 11 by reading or connecting to the server computer via the communication interface 20 and downloading the parameter setting program or data from the server computer. You may make it make it.

  In the above description, the parameter setting device or the parameter setting program incorporated in the musical sound generating device 1 has been described. However, the parameter setting device can be a single device, and the parameter setting program can be recorded on a recording medium in various ways. It can be possible to be incorporated in a musical tone related apparatus.
