Being mildly obsessed with the FS1R definitely helped, I found pages like this one that helped me understand how to generate formants without using a bandpass filter: http://www.sitepassenger.com/thomas/fs1r/heart.html How I did it: I recorded the FS1R in Ableton Live, sweeping different parameters, then zoomed in and looked at the shape of the waveforms it produced. Also Flash's spectral view helped a lot, I was expecting to see a cluster of overtones (like a formant) so I could see when my algorithm was incorrect. It turns out that you can generate a formant using two sine oscillators; the first sine resets the phase of the second sine at the end of each cycle (i.e. oscillator sync). Also the first sine controls the amplitude of the second sine (similar to ring modulation). Pretty neat. Thanks Jeremy!
