I'm looking into distortion designs for a dsp class.

It seems the JCN megadist on
http://www.csounds.com/jmc/Processors/Processors.htm are accompanied
by a pdf with the implemented formula and transfer function,
but I can not open the pdf, my acrobat reader syas there's something
wrong with the file.
Does anyone have a working copy of the file ?
Josep are you still here ?

Also, on the same subject, I would like to look into the source code
for the distort1 and clip opcodes to see if I can understand how they
work. I have trouble finding the source code, is there a "map"
somewhere, telling what files contain the source code for specific
opcodes ?

very best
