A music producer and member of KC and the Sunshine Band pleaded not guilty to charges he had sexual contact with teenage boys.
Richard R. Finch appeared in Licking County Common Pleas Court, Ohio.
He was arrested last month and faced 16 charges relating to sexual conduct with teen boys.
Magistrate Mattie Klein doubled Finch's bond to 500,000 US dollars, and ordered him not to have contact with the alleged victims or anyone under 18 years old.
Michael Connick, Finch's lawyer, had asked that bond be reduced.
Finch is a former bass player for the band and a seven-time Grammy Award winner. He is being held in the Licking County Jail.
