This sounds like just using the magnitude of one signals frequency bins
to amplitude-modulate a second signals frequency bins. I thought
convolution actually affected the frequencies in a slightly different
way. Or rather convolution was multiplying the frequancy magnitudes but
also multiplying the two frequency values as well.

I know you can use block~ to change sample block size, but I have never
seen the second argument. What does this second argument do (its not in
the pd help)?
