Title: Device and method for generating a picture and/or tone on the basis of detection of a physical event from performance information

Abstract: When performance information, such as MIDI data, is input, physical events or phenomena are simulated on the basis of the input performance information, and computer graphics or CG parameters and tone parameters are determined on the basis of the simulated results. The determined CG parameters are passed to a general-purpose CG library, while the determined tone parameters are passed to a tone generator driver. The general-purpose CG library generates data representing a three-dimensional configuration of an object on the basis of the received CG parameters, and executes a rendering operation to generate two-dimensional picture data on the basis of the three-dimensional data, so that the thus-generated two-dimensional picture data is visually displayed. The tone generator driver generates a tone signal on the basis of the received tone parameters, which is audibly reproduced as an output tone. By thus controlling the tone and picture collectively, it is possible to accurately simulate a performance on a musical instrument on the real-time basis.
