Abstract
An electronic musical instrument having a common memory, a tone generator and a control section. The common memory stores a plurality of musical tone parameters and is accessed by the tone generator and the control section. The tone generator generates a musical tone based on the musical tone parameters stored in the common memory and writes a musical tone parameter indicating the current state of the musical tone being generated by the tone generator, in the common memory. The control section directs the tone generator to generate a musical tone by writing the plurality of musical tone parameters corresponding to the musical tone in the common memory and controls the tone generation by monitoring the current state of the musical tone based on the musical tone parameter stored in the common memory. In the electronic musical instrument, the load of the control section for controlling the tone generator is reduced, and the circuit sizes of the control section and the total memory capacity required for the electronic musical instrument are also reduced.
