FM Voices, Bells, etc. Great project. Chowning's major papers are "Synthesis of Complex Spectra" "ONE ON VOICE I CAN'T REMEMBER THE TITLE" and "Synthesis of Moving Sound Sources" I'll see if I can locate them for you. In the interim, try to listen to his composition "Phone." Should be in the library, but if not, I can drop an MP3 where you can get to it. Forge Ahead!!
