1. A vibrato signal generating arrangement for an electronic musical instrument comprising:

  • envelope signal generating means for generating an envelope signal which changes from a first potential level to a second potential level in response to and at the instant of key depression, and thereafter changes gradually from said second potential level to said first potential level;

    clipping means coupled to said envelope signal generating means and having a predetermined clipping level between said first and second potential levels for clipping off a portion of said envelope signal between said second potential level and said clipping level; and

    vibrato signal generating means coupled to said clipping means and driven directly by the output of said clipping means so as to be operative to produce a vibrato signal, said vibrato signal generating means being so arranged that it does not operate at a signal level of the output of said clipping means corresponding to said clipping level and produces the vibrato signal in response to a signal level of the output of said clipping means other than the signal level corresponding to said clipping level and at an amplitude in accordance with the signal level of the output of said clipping means.
