PARAMETER SETTING APPARATUS, AUDIO SIGNAL PROCESSING APPARATUS, PARAMETER SETTING METHOD AND STORAGE MEDIUM

摘要

A parameter setting apparatus includes: a real control adapted to detect value modification operation for modifying a value of a parameter; and a display device adapted to detect touch operation and displaying virtual controls corresponding to a plurality of parameters respectively. In an unlock state, an assigner assigns a parameter corresponding to a touched virtual control to the real control, and in a lock state, the assigner does not change the assignment of the parameter even if detecting a touch operation. In response to the value modification operation of the real control, the parameter setting apparatus modifies the value of the parameter assigned to the real control if the operation is performed during the touch operation, or the value of the parameter corresponding to the touched virtual control if the operation is performed during the touch operation.

1. A parameter setting apparatus comprising:
a real control adapted to detect modification operation by a user on the real control for modifying a value of a parameter; a selector adapted to select one of lock state and unlock state; a display device adapted to display virtual controls respectively corresponding to parameters and detect a touch by the user on any of the virtual controls; an assigner adapted to assign, when the touch on one of the virtual controls is detected in the unlock state, the parameter corresponding to the touched virtual control to the real control, and to keep the assignment of the parameter to the real control even when the touch on one of the virtual controls is detected in the lock state; a modifier adapted to modify a value of the parameter assigned to the real control in response to the modification operation while the touch on none of the virtual controls is detected, and modify, while the touch on one of the virtual controls is detected, a value of the parameter corresponding to the touched virtual control in response to the modification operation.
