[sdiy] harmonic generator

[mark verbos]

you could try using Jürgen Haible's wave multiplier for the x3,x5 and x7 
ones or the timbre section in the Buchla 208. the Buchla distorts the 
input at a variety of levels and then combines it back together to get a 
multiplied frequency. In the actual Buchla 208 it comes back a kind of 
odd shape, but it was using a sine as the input wave. With a triangle, 
you may be able to tweak it into submission;) You wouldn't need all the 
stages for all the multipliers either. Maybe you could try tweaking the 
break points. This could get ugly.

the even numbers are a simple matter of full wave rectification. Then 
you need 10 tri to sine converters.
