ABSTRACT:
A tone generation apparatus for an electronic keyboard instrument which stores key information for at least one channel in an assignment memory (33), and sets tone source parameters of a tone generator (19) according to the key information is disclosed. A key ON/OFF register (31) having a bit string corresponding to key numbers stores key ON/OFF information. When a key corresponding to the currently tone-ON key information stored in the assignment memory (33) is released, ON key information in the register (31) is searched by a search block (32) from, e.g., the high pitch side. If another ON key information is detected, the content of the assignment memory (33) is changed to the key information so as to generate a corresponding tone.
