A VCA, of course, those things are so useful. I can't wait to get more.

In a similar vein, you can "exponentiate" oscillator waveforms by
feeding an output into it's own exponential input. A good example is
to feed the triangle output back into FM2. Watch the shape of the
triangle output on a scope as you twist the FM2 knob. Works well with
saws and sines as well. Now imagine how much fun you can have if the
signal driving the FM2 input goes through a VCA: more voltage
controlled waveforms.
