ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an acoustic signal producing apparatus capable of issuing musical tone signals produced at its internal tone generator together with acoustic signals applied thereto from an external device such as a microphone, an electronic musical instrument or the like.
2. Description of the Prior Art
In recent years, there has been proposed an acoustic signal producing apparatus of the type which includes means for applying musical effects to musical tone signals produced at its internal tone generator. On the other hand, there has been proposed an acoustic apparatus capable of applying various musical effects to acoustic signals supplied thereto from an external device such as a microphone or the like.
In the prior art, however, the musical effects are independently applied to the musical tone signals and the acoustic signals at the respective apparatuses and separately controlled. It is, therefore, needed to separately change each applying state of the musical effects. This causes troublesome in manipulation of both the apparatuses.
SUMMARY OF THE INVENTION
Accordingly, it is a primary object of the present invention to provide an acoustic signal producing apparatus capable of simultaneously applying various musical effects to musical tone signals produced at its internal tone generator and acoustic signals supplied from an external device such as a microphone, an electronic musical instrument or the like and of changing each applying state of the musical effects in a simple manner.
According to the present invention, the object is accomplished by providing an acoustic signal producing apparatus which comprises tone generator means to be applied with tone pitch data indicative of a tone pitch for producing a musical tone signal of the tone pitch; input means to be applied with an acoustic signal from an external device; musical effect applying means for applying a musical effect to the musical tone signal and the acoustic signal supplied from the tone generator means and the input means and for changing an applying state of the musical effect in accordance with an effect control parameter separately supplied thereto; and automatic performance means provided to memorize the tone pitch data and the effect control parameter in a time series for successively supplying the memorized tone pitch data and effect control parameter to the tone generator means and the musical effect applying means.
According to an aspect of the present invention, there is provided an acoustic signal producing apparatus having an operation panel provided with a manual switch, which signal producing apparatus comprises tone generator means to be applied with tone pitch data indicative of a tone pitch for producing a musical tone signal of the tone pitch; input means to be applied with an acoustic signal from an external device; musical effect applying means for applying a musical effect to the musical tone signal and the acoustic signal supplied from the tone generator means and the input means and for changing an applying state of the musical effect; and switchover means for switching over the applying state of the musical effect in response to operation of the manual switch.
According to another aspect of the present invention, there is provided an acoustic signal producing apparatus wherein the switchover means comprises means for controlling the tone generator means in response to operation of the manual switch to switch over a tone color of the musical tone signal produced at the tone generator means.
