You should be able to get harmonic distortion using Waveshaping (ie
Non-linear distortion) - requires knowledge of Chebychev Polynomials etc
-see Csound manual & Dodge & Jerse book.

You can also get some nice distorted input sound using FM, ie Frequency
Modulation of a complex waveform rather than sinewave. The amount of
distortion then becomes controllable using modulation index.
