A second transfer function models the cyclic oscillation produced by opposing effects of two force sources representing the cyclic oppositional action of muscle systems. A third transfer function emulates the response of muscles to internal electrical impulses. A fourth transfer function provides a model representing and altering virtual trajectory of gestures. A fifth transfer function models visco-elastic properties of muscle response to simulated loads. The gesture synthesizer outputs <DEL-S DATE="20020416" ID="DEL-S-00002" / >MIDI-compatible<DEL-E ID="DEL-S-00002" / > continuous pitch data, tone volume and tone timbre information.

As the user executes a performance on a preliminary or trial basis, performance data based on the user's performance are evaluated, a performance tendency of the user is extracted as a result of the extraction, and then, performance tendency information, indicative of the extracted performance tendency, is generated. Psychological state, such as a mood or feeling, of the user is detected from the performance tendency, and feeling information, indicative of the detected psychological state, is generated. Then, tone color control information corresponding to the generated feeling information is acquired from a storage section, such as a “mood / feeling” vs. tone color control” correspondence table, the acquired tone color control information is delivered to a tone generator, and desired tone color parameters are set on the basis of the tone color control information.
