Claim:
1. A musical sound control apparatus, comprising: an operator which has an index portion and which changes values of a plurality of kinds of parameters by moving a position of the index portion; a parameter selection unit which selects a parameter assigned to the operator from among the plurality of kinds of parameters; and a processor which executes processing of (i) changing a value of the parameter selected by the parameter selection unit according to an operated position to which the index portion was moved from a standard position, and (ii) not changing a value of a second parameter assigned to the position indicated by the index portion, when changing an assignment to the operator from a first parameter among the plurality of kinds of parameters to the second parameter when the second parameter is selected by the parameter selection unit in a state in which the position indicated by the index portion is not the standard position, so as to suppress a situation in which a value of the second parameter changes rapidly after changing the assignment to the operator from the first parameter to the second parameter selected by the parameter selection unit.
