We propose a system that automatically calibrates Modified FM synthesizers. Reproducing the sounds of musical instruments has been successfully achieved by many audio synthesis techniques. However, this task can be difficult and time-consuming especially when there is not intuitive correspondence between a parameter value and the change in the produced sound. Searching the parameter space for a given synthesis technique is, therefore, a task more naturally suited to an automatic optimization scheme. Using a genetic algorithm and a fitness function based on harmonics analysis, our system is able to automatize the calibration of a ModFM synthesis model for the reconstruction of harmonic instrument tones.
