AES Journal, September 2008 on split side-band FM synthesis.
I tried it out, it was pretty cool. Interesting sounds and
harmonic content. I like it. It works well. Victor did a good
job putting that together. Check the December (I think) issue 
for posting of the correction of a typo regarding a Taylor 
Series equation. I'm betting it wasn't Victor's typo.

It was a cool paper. I've about worn out that issue for all
the times I've been going back to refer to it. 
Victor, you done good.


Enjoy, cheers,
-Partev

Hi,

Victor hasn't chimed in, but he develop a methd of producing
bandlimited pulses and other waveforms using FM. He wrote an article
about this for AES, the Csound journal and others.

Some more information:
There's an example in QuteCsound showing the difference between
band-limited and non-bandlimited oscillators (with and without
interpolation).

Cheers,
Andrés

Thanks for your comment and Andres, for mentioning other work; re: VA 
oscillators, we
have a new article which should be coming out in the spring issue of CMJ. 
It's a bit of a survey,
but with a couple of new algorithms. Anyone interested, please contact me 
privately and I can
provide a PDF when it's out.

Victor
