Abstract:
An apparatus for tone control, comprising:storage means for storing a plurality of signal processing modules representative of algorithms according to which a tone signal is processed, each of said plurality of signal processing modules including a plurality of data groups; said storage means including a plurality of storage areas for said plurality of signal processing modules, each of said storage areas being divided into a plurality of division areas, and each of said division areas being assigned to a different one of said plurality of data groups; transfer means for transferring said plurality of signal processing modules to said storage means in such a manner that corresponding division areas in said plurality of storage areas store one of said plurality of data groups; address qualifying information transfer means for transferring address qualifying information that includes a size difference between a size of a specified data group of one of said signal processing modules and a size of a specified division area that stores the specified data group of said one of the signal processing modules, if the size of the specified division area is greater than the size of the specified data group, when said transfer means transfers the specified data group to the specified division area; signal processing means for sequentially executing said plurality of signal processing modules to thereby process the tone signal; and address control means operable in response to an operation of the address qualifying means for determining a start address of a next specified division area for a next specified data group in accordance with the size difference in the address qualifying information when said signal processing means has completed executing the signal processing module including the specified data group.
