From 1931-5 he was music director of the Pathé-Nathan studios, where he conducted not only his own scores but those of Arthur Honneger and Darius Milhaud. He makes a cameo appearance as a conductor in Kurt Bernhardt's La Nuit de décembre (1939). As a journalist he championed many composers, including Kurt Weill.
In Vigo's Zéro de conduite he played recorded sounds backwards to accompany a slow motion sequence, anticipating a favorite technique of musique concrète.
François Truffaut made extensive use of his music in the late 1970s.
