Abstract
An electronic musical instrument has a processing circuit for adding a reverberation tone after volume control using expression data generated upon operation of an expression pedal to generate tone data which does not vary the attenuation characteristics of the reverberation tone by operation of the expression pedal. The volume control and reverberation tone addition are implemented by a digital signal processor. Auditory sense correction of the volume control is also done by exponentially transforming expression data.
