I first thought "Elite Sinus Producer" and "The Sinus Creator" were trackers specifically designed for creating nasal-sounding music; but of course the explanation for why the term "sinus" came to be used instead of "sine" is likely because many demosceners were from a native European background, and their language retained the Latin origin word instead of deprecating its usage in favour of "sine", as happened in English.
