This is by far the best sounding of the three IMHO. For kicks I threw the output
up on a 'scope. 

With a triangle wave input (5v p-p).

As you bring the modulation knob up, the waveform increases in amplitude to
a normal triangle (at around 8 o'clock).
As you continue to bring the knob up the peaks of the waveform flip over and
start heading in the opposite direction.
When they get to the opposite side, (around 9 o'clock) they flip again and start
heading in the opposite direction and so forth until, with the knob fully up you have
about eight mini triangles at the zero crossing points.
I can't "sus" this one out but it looks like a series of breakpoint generators
with each breakpoint (at 700 mv. steps maybe?) providing alternating +/- gains.

Whatever it is: Feed in a low freq. sine wave input. Modulate this with a random
voltage generator set very slow. Feed that into a BIG artificial reverb (Midiverb II Patch 29 :^)
and it sounds almost as good as the intro to "Between the Sun and the Rain" (Beaver&Krause).
