Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICABILITY The present invention relates to a tone generator that differs from a tone generator other than the tone generator that is currently sounding according to the strength of a key pressing force (hereinafter referred to as after touch). The present invention relates to an electronic musical instrument for producing a sound. 2. Description of the Related Art In recent years, an electronic musical instrument detects after touch in order to enrich the expressiveness of performance. Hereinafter, an example of the above-described conventional electronic musical instrument will be described with reference to the drawings. FIG. 3 and FIG. 4 show the main components of a conventional electronic musical instrument. In FIG. 3, 1 is a keyboard, 2 is a scale discriminating means, 3 is an after touch detecting means, and 4 is a processing means for issuing a tone generation command to a tone generator 5 based on the detected scale information and after touch information. is there. In FIG. 4, 1 to 5 are the same as in FIG. 6 is VCA
(Voltage-controlled amplifier) or VCF (Voltage-controlled filter). The operation of the electronic musical instrument configured as described above will be described below. First, the operation of FIG. 3 will be described. After the musical scale information and the after touch information are processed by the processing means 4 for generating sound using the scale discriminating means 2 and the after touch detecting means 3 from the first key, a tone generation instruction to the tone generator 5 is issued. Will be issued. Then, when the level of after touch changes, the after tone is applied to the tone generator that is currently sounding.
The timbre can be changed by outputting a parameter related to touch. Next, the operation of FIG. 4 will be described. The scale information obtained by the scale discriminating means 2 from the keyboard 1 is processed by the processing means 4 for sounding, and a sounding instruction is issued to the tone generator 5,
After passing through the VCA / VCF control means 6, it is output as audio. At this time, VCA and VCF are controlled based on the after touch information obtained by the after touch detection means 3 and the tone can be changed. Problems to be Solved by the Invention However, in the above-described configuration, the tone color can be changed only for the sound that has already been sounded, so that the expressive power of the performance has not been enriched. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides an electronic musical instrument capable of producing a rich expressive performance by producing a sound different from a sound source that is currently being produced. Means for Solving the Problems In order to solve the above problems, the electronic musical instrument of the present invention comprises a keyboard, a scale discriminating means, a control panel for selecting a timbre, a processing means for generating a sound, and an after touch. The electronic musical instrument includes a determining unit that outputs a sounding instruction to a tone generator that is not currently sounding by a detecting unit. Effect of the Invention The present invention is improved by the above-described configuration in that conventionally, only after-sound information can be added to only a sounding sound source, and is different from a non-sounding sound source. Producing the tone can enhance the expressive power of the performance. An electronic musical instrument according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a main configuration diagram of an electronic musical instrument according to a first embodiment of the present invention. 1 is a keyboard, 2 is a scale discriminating means, 3 is an after touch detecting means, 4 is a processing means for sound generation, 8 is a control panel for selecting a tone to be sounded in advance according to the strength of after touch. Is a tone generator that is sounding, 6 is another tone generator that is not sounding, 7
Is a determination means for determining whether or not to generate a sound depending on the level of after touch, and outputting a sound generation command to the tone generator 6. Regarding the electronic musical instrument configured as described above,
The operation will be described with reference to FIGS. First, the operation of FIG. 2 will be described. FIG. 2 shows a configuration in which n units of FIG. 1 are provided and each output is mixed by a mixer 9. The scale information obtained from the keyboard 1 by the scale discriminating means 2 is processed by the processing means 4 for sound generation, and a tone generation command of a preset tone is issued to the tone generator 5 by the control panel 8. Further, the after-touch strength is detected by the after-touch detection means 3, and is determined by the sounding command output determination device 7 based on the strength,
A tone generation command of a preset tone is issued by the control panel 8 to another tone generator 6 that is not sounding. Here, for example, if the control panel 8 is set in advance so that the tone of the organ is emitted when the key is first pressed, and the tone of the strings is emitted when the key is pressed more strongly, the organ is played when the key is first weakly pressed. When the tone is further pressed from the tone generator 5, the strings are sounded together by the tone generator 6 which is not sounding when the keys are pressed. In the case of an electronic musical instrument, since there are a plurality of keys, the outputs of the keys 1 to n are mixed by the mixer 9 and output as a tone. As described above, according to the present embodiment, when the after touch is strong, a tone generator that is not producing sound can produce a different tone color, thereby enriching the expressiveness of the performance. In the first embodiment, the tone generator
A tone set in advance by the control panel 8 is set in 5, 6; for example, an organ tone is set in the tone generator 5 and a string sound is set in the tone generator 6 in advance. May be set. In the first embodiment, the scale discriminating means 2, the after touch detecting means 3, the processing means 4 for sound generation,
Although the sounding instruction output judging devices 7 are formed independently of each other, they may be centrally processed at one place by using a microcomputer. Effect of the Invention As described above, the present invention makes it possible to enrich the expressive power such as the thickness of a sound by causing a tone generator that is not sounding to generate a different tone depending on the strength of after touch. .
