ABSTRACT:
An expression means has been developed which can accentuate only a selected musical sound, e.g., melody, out of melody, accompaniment chord and bass sound generated in an electronic musical instrument and does not accentuate other sounds. The expression means of the present invention produces a first electric potential that will vary in response to an operation of an expression pedal and a second potential that will vary in response to a slow operation of the expression pedal though irresponsive to a quick operation of it. For gain control of amplifiers that deal with musical sounds required to be accentuated, said first potential is prepared, and for gain control of other amplifiers that deal with musical sounds free from accentuation, said second potential is prepared. Furthermore, the expression means of this invention employs changeover switches to realize arbitrary choice of the sounds to be accentuated.
