In an echo effector for imparting an echo effect to an audio signal based on values of a plurality of parameters, a memory is provided for memorizing an interrelationship among the plurality of the parameters which are mutually related to each other. A dial is actuated for independently setting one or more of the parameters to desired values. A microcomputer dependently sets the remaining parameters to appropriate values according to the desired values and the memorized interrelationship. Further, in a sound field effector operative according to a selected program for creating an effect simulative of a sound field in matching with a room situation under which the effector is installed, a program memory stores a plurality of programs which can be selected in terms of types of sound fields and types of room situations. A first switch is operated for designating a desired type of a sound field. A second switch is operated for designating a desired type of a room situation. One program is selected from the program memory according to both of the designated type of the sound field and the designated type of the room situation. |

DETAILED DESCRIPTION As noted above, the conventional echo effector and the sound field effector are not designed in taking account of many and unspecified users thereby suffering from poor operability and complicated initial setting.
In view of the drawbacks of the prior art, an object of the invention is to provide an effector exhibiting improved operability for many and unspecified users, when applied to a karaoke amplifier or the like.
According to a first aspect of the invention in an effector for imparting an effect to an audio signal based on values of a plurality of parameters, a parameter setting apparatus comprises memory means for memorizing an interrelationship among the plurality of the parameters which are mutually related to each other, first setting means for independently setting one or more of the parameters to desired values, and second setting means for dependently setting the remaining parameters to appropriate values according to the desired values and the memorized interrelationship.
In operation, one or more of the parameters is manually set while the remaining parameters are automatically set by computation dependently on the manually set parameter(s).
Therefore, the free setting of one parameter does not cause unwanted variation of other parameters, thereby avoiding the effect from deviating from a desired condition.
Further, the user does not need to adjust all of the parameters.
According to a second aspect of the invention, in an effector for imparting an effect to an audio signal according to a value of a parameter, a parameter setting apparatus comprises input means having a scale composed of ordered marks for normally pointing a mark in order to set the parameter, and for occasionally inputting a command to change a range of the parameter, memory means for memorizing a correspondence between the scale of the input means and the range of the parameter, determining means for determining a value of the parameter within the range according to the pointed mark based on the memorized correspondence between the scale and the range, and changing means operative according to the command for rewriting the correspondence between the scale and the ranger memorized in the memory means so as to effect the change of the range
