Abstract
In construction of an electronic musical instrument having plural musical tone controllers such as keys, push buttons and an expression pedal unit, a number of pulses are generated depending on the extent of movement of each controller on output lines whose number is smaller than that of the pulses so generated and musical tone control parameters such as tone volume, tone color and tonal pitch are changed in multi-stage fashion in response to the pulses generated. Generation of musical tones is assured whilst well reflecting delicate change in player's emotion via subtle key touch control.
