Abstract

A musical tone generating apparatus includes a position information generating device to generate musical instrument position information (PS) as plane coordinates values. This information (PS) is stored in a memory device, or selectively determined by a manual operation. The apparatus also includes an information converting device to convert information (PS) into musical tone parameter control information (PD). This control information (PD) controls musical tone source signals (S11, S12, and S13) to generate a sound field corresponding to the position of musical instruments arranged on a stage.This enables an operator to verify the musical instrument positions on a stage, thereby providing a feeling of being at a live performance.
