Audio signal controller

摘要

It is determined whether user's operation performed on a control is normal or special operation. A function of increasing or decreasing a value of a parameter assigned to the control is performed if the user's operation is the normal operation. Another function, different from the function of increasing or decreasing a value of a parameter, is performed if the user's operation is the special operation. The control comprises, for example, a touch pad provided with a display device for displaying a current operating position of the control. If a user touches one point of the pad with its finger or touches one point of the pad and then continuously slides its finger on and along the pad, such user's operation is determined to be the normal operation. If the user touches or taps two or more points of the pad, such user's operation is determined to be the special operation.

1. A controller, comprising:
a control operable by a user and having a parameter related to audio signal processing assigned to the control; a determination section which determines whether the user's operation of the control is a normal operation or a special operation; and a processing section which performs a function of increasing or decreasing a value of the parameter assigned to the control in a case where said determination section has determined that the user's operation of the control is the normal operation, but performs another function, different from said function of increasing or decreasing the value of the parameter assigned to the control, in a case where said determination section has determined that the user's operation of the control is the special operation, wherein the control has an area operable to detect the user's operation of the control, the area including a first region and a second region different from the first region, wherein said determination section determines the user's operation of the control to be the normal operation in a case where a first-type input of the user is detected in the first region and in a case where the first-type input of the user is detected in the second region, wherein said determination section determines the user's operation of the control to be the special operation in a case where a second-type input of the user is detected in the first region, the second-type input being different from the first-type input, wherein the special operation includes a first special operation and a second special operation, and said determination section determines the user's operation of the control to be the first special operation in the case where the second-type input of the user is detected in the first region, and said determination section determines the user's operation of the control to be the second special operation in a case where the second-type input of the user is detected in the second region, and wherein said processing section performs a first function in a case where said determination section determines that the user's operation of the control is the first special operation, and performs a second function different from the first function in a case where said determination section determines that the user's operation of the control is the second special operation.
