Abstract
An envelope wave shape for each musical tone wave shape is generated per each key operation. The rate of change of the envelope wave shape to be generated are switched at timings corresponding to key operation speed of an operated key, thereby enabling an electronic musical instrument to generate musical tones of different envelope patterns depending on key operation speed just like on a pipe organ.
