Sure:
A good tutorial article was C. Roads 'ATutorial on non-linear Distortion or
Waveshaping synthesis' CMJ 3(3):29-34 1979.,
reprinted in Foundations of Computer Music,MIT Press 1985.
The classic early writer on waveshaping wasJames Beauchamp, try
'Brass tone Synthesis by Spectrum Evolution Matching with Non-linear
functions'
CMJ  3(2):35-43 1979, also repinted Foundations of Computer Music..
and the best technical treatment I know of was Marc LeBrun 'Digital
Waveshaping Synthesis',
Journal of the Audio Engineering Society 27(4):250-266, 1979

Hi,

I'm not sure whether this is considered good form or not, so I apologize
beforehand if it is.

The MIT Press will have an exhibit at ICMC, so please stop by if you'd like
to look through Foundations of Computer Music or any of the other Computer
Music books published by The MIT Press. We'll also have the draft
manuscript of The Csound Book, edited by Richard Boulanger, on hand.

-Doug
