Who is the Catholic patron saint of sound and lighting technicians?

There don't seem to be any specific to that profession, however, there are some that are close enough to merit the task:

St. Dunsten and St. Venerius the Hermit, both are patrons of lighthouse keepers

St. Eramus of Formiar and St. Elmo are patrons of pyrotechnicians

St. Gabriel is patron of radio workers and broadcasters

St. Isidore of Seville is patron of computer technicians, users and programmers
