A gotcha that may be biting you is that each time you change one or more of

Yes, I was wondering about this! In the debugger I kept getting different
IDs and didn't know why. I had thought that "hooking" one filter's input to
another's output was a fixed relationship (until reset), but this makes
sense. Using this bit of info, I can now cascade filters for combo
functionality. It works really well, and I'm amazed at how little CPU it
takes! This is powerful stuff indeed.
Thanks!
