In 1983 he met the singer Liane Foly and in addition to becoming her partner, he composed her first successes, including Au fur et à mesure and Doucement.

He also wrote for such artists as Michel Petrucciani, Richard Galliano, Charles Aznavour, Freddy Zucchet, Gilbert Bécaud, Diane Dufresne, Nicole Croisille, Natacha Atlas, Viktor Lazlo, Janet Jackson, Myriam Abel, Camille Bazbaz et Malia.

He was also in the transmission of T'empêches tout le monde de dormir (You stop everyone sleeping) on M6 presented by Marc-Olivier Fogiel where he portrayed in his manner the "Psycho-erotico-cosmico-musical" of the guests by translating the name of a personality in shorthand notes with a melody which he composed and played on the synthesizer.

Since 21 February 2007 he has presented Dédé les doigts de fée (Dede nimble fingers) on Paris Première, a program about guests who have different music backgrounds.

To better portray his guests, Manoukian invites them to recount their lives in a real recording studio and he then composes a novel piece of music based on their stories.

In the same year Manoukian composed the new Album (music) for Beverly, a contestant in Nouvelle Star 4 and he also accompanied Miss Dominique at the piano during some of her concerts.
