Implement the faders as pre-effect volume, and Modulex will get it's own
post-effects volume slider that can be modulated with CCs...

I'm going to make a determined effort to knock out all of the bugs I can now,
to ensure that release doesn't get delayed...  If I can finish that soon
enough, I may start carefully adding feautures again, or if not, I'll
start adding features again after release...
