In a musical tone signal producing apparatus having a read-only memory of ROM for memorizing a start program and a random access memory or RAM for memorizing plural sets of system setting data and a designation data, a central processing unit or CPU is provided to execute the memorized start program to transfer an application program to the RAM from a hard disk. Immediately after started execution of the application program, the CPU sets a system environment of the apparatus on a basis of one set of the memorized system setting data designated by the designation data and changes the memorized system setting data and designation data during execution of the application program. During execution of the application program, the CPU executes sampling processing, trimming processing and mapping processing of the application program in sequence to produce a musical tone control data.
