uh, writing code in macros sucks. i really think for nontrivial plugins
it's a negligible performance boon for a lot of code bloat/ugliness.
(consider that most plugins already do a lot more computation than this...)
btw, there's a setRunAddingGain() for trivial gain control,
but ultimately, for real flexibility
eg smoothing gain controls, separating the mixing from the plugin is the
way to go.
