Abstract
In controlling a sound source for an electronic musical instrument, an operation data of a performance operation member corresponding to musical tone control parameters of a musical instrument is corrected according to a tone generation region characteristic of the musical instrument. The corrected data is inputted to a sound source circuit of the electronic musical instrument thereby a musical tone approximating of the musical instrument is regularly generated. The electronic musical instrument comprises a performance operation member for outputting position and pressure data of an operation member, a sound source for receiving musical tone control parameters corresponding to those of a musical instrument and generating a musical tone simulating that of the musical instrument, and a conversion circuit for converting the position and pressure data to those in a normal tone generation region as the musical tone control parameters in accordance with a tone generation region characteristic based on the musical tone control parameters of the musical instrument. The conversion circuit is connected to the sound source.
