Claim 1
Independent Claim
128 words
An automatic rhythm performance device comprised of: a counter circuit connected to a tempo oscillator having variable frequency; inverting circuits including serially connected resistant circuit networks, differentiation circuits and inverting rectifiers, said inverting circuits being connected to said counter circuit; clipper circuits including serially connected resistant circuit networks, clippers and differentiation circuits, said clipper circuits being also connected to said counter circuit; rhythm selectors connected to predetermined circuits of said inverting circuits and said clipper circuits; percussive sound generators connected to said rhythm selectors and a speaker whereby the output signals out of said counting circuit is synthesized by means of said inverting circuits and said clipper circuits to provide a pulse train of a desired rhythm and to actuate said percussive sound generator by said pulse train.
