Also, here's a tip: if you change the contents of the IR table, you have to switch away and switch back for it to take effect. I guess it's loading the table to internal buffers and skips loading it if the requested table has the same name as the previous one.

I think it's interesting to watch the averaging happen as the frequency goes beyond the size of the wave table, more interesting than the interpolation.

But wait! I just checked the harmonics of a full wave rectified {cos~] and all the even FFT terms have positive magnitude, so this post appears to be correct. And now I just reran my first test and set my "top only" slider to exactly 2 and am getting the fundamental + all even harmonics. Why am I getting so tripped up by this?!!! -

Even are not emphasized in single ended, even are canceled in balanced.
This is definitely closer to what my experiment implies, thanks.
Edit: I think it's things like this that misled me in the first place--what I now believe to be false statements are highlighted in yellow:

symmetric vs asymmetric clipping.pd

The osc~ frequency is set so that it perfectly fits a 64 sample block, which make the FFT’s terms match the harmonics of the input.When I increase the top and bottom clipping amount, the wave shape approaches a square wave and the harmonic content matches theory—all odd numbered harmonics, meaning harmonics that are odd multiples of the fundamental. Now I’ve read that even harmonics are emphasized in asymmetric signals, harmonics that are supposedly warmer and richer and are of the kind produced by single-ended tube stages, all of which have asymmetric current gain curves. That’s what my “top only” slider is crudely simulating. But the FFT contains both even and odd harmonics and there doesn’t seem to be any bias towards even harmonics, unless their mere presence is the magic sauce. What am I misunderstanding?
Edit: I was curious whether my heavy-handed asymmetric clipping was at fault, but this gentler version has similar (if not worse) characteristics.
