It may have been discussed somewhere earlier. However, I just wanted to point out that there is a bracing error in the impulse activation expression on the popnet of the shockwave tutorial in v 7.0.231 help files.
This expression needs one more brace preceeding the expression to eval correctly.

Here's the correct expression as I figure it was intended.

((clamp($FF, 2, 3 * 20+20/2)%20)<=1)

Mark, I can't thank you enough.

I've created an usable approximation of a pulse by manipulating params in the pulse chop, however what you've posted seems to be far closer to the real deal. This is a great learning tool. I'm already tearing it apart.

Good suggestion. Thats what I've done. However, I've generated the shape of the curve using the Pulse Chop. That way its fully procedural.
