Satu lagi penata musik film Indonesia. Ia bisa dibilang setelah Idris Sardi, dan stylenya juga beda. Idris mencampur unsur klasik dan musik trend saat itu. Tapi Gatoto justru di era modern, dimana dia memakai Electronic Instrumen dengan synthesizer. Tapi kiprahnya cukup banyak musik film yang di hasilkannya, ada 138 Film.
Lahir di Mojokerto. Pendidikan : Akademi Seni Rupa (tk. II) IKIP Surabaya, Akademi Musik (tk. I) LPKJ/TIM Jakarta. Ayahnya yang pemusik semula tidak menghendaki Gatot Sudarto menjadi pemusik pula, sebab si Bapak tidak bisa hidup enak dari musik. Tapi Gatot jadi pemusik juga, dan bisa hidup enak dari musik. Tentu saja baru tahun-tahun belakangan ini. Tadinya Gatot adalah "anak band" yang memulai karirnya di "Bhatara" Surabaya pada 1967, lalu hijrah ke Jakarta pada 1969. Setelah berpindah-pindah dari band yang satu ke band yang lain, Gatot menetap pada The Beibs (sejak 1973) dan Irama Nada (sejak 1974) sampai sekarang, 1978. Sejak 1973 itu pula Gatot mulai ditarik untuk menangani illustrasi musik film "bing Slamet Dukun Palsu", atas ajakan Sutradara Motinggo Busye. Sejak itu hampir 40 film telah ditanganinya. Diantaranya "Ateng Minta Kawin" (1974), "Sayangilah Daku" (1974), "Tarzan Kota" (1975), "Sebelum Usia 17" (1975), "Buaye Gile" (1975), "Tiga Cewek Indian" (1976), "Inem Pelayan Sexy" (1976), "Menanti Kelahiran" (1976), "Cinta Abadi" (1977), "Ateng Bikin Pusing" (1977), "Akibat Pergaulan Bebas" ('77), "Sejuta Duka Ibu" (1977), "Si Genit Poppy" (1978), dll.
