Control oriented implementations of neural network models and memory-based models are developed and compared. These techniques model the spectral data from instruments as opposed to the physical sound production mechanism. Both model types are for real-time control and use controller inputs such as pitch, loudness, and brightness functions to produce frequencies and amplitudes for sinusoidal components in an additive synthesizer. Both approaches produce acceptable synthesis results. Network models are compact but inflexible as the data is discarded after learning. Memory models are more memory intensive and maintain the data for local reference. Experiments with wind instruments and singing voice are presented.
