ABSTRACT:
Disclosed is a system of sound generating units for generating musical sounds according to a sequential order in electronic musical instruments such as instruments comprising a keyboard, an electronic drum apparatus, a rhythm machine or an automatic performing or accompanying apparatus. Consecutive note-on messages are processed to identify musical tones generated by the same notes, whereafter the same tones are superposed. This enables a well balanced generation of sounds between the sound generating units as the units generate sounds in a circulative sequence in response to performance controlling messages that are received by the units, according to a preferential order. The system of the present invention further provides a good reproduction of volume changes in composite musical tones, which changes are due to attenuation caused by a new note-on message that alters the volume of a musical tone as such tone is generated in response to a previous note-on message.
