I'm still having trouble stating it clearly.
DSP modules and hosts should not have to deal with parameters changing
in the middle of the process() cycle. Once the cycle begins, all
parameter values (including any sample-accurate mid-buffer changes)
must remain consistent while *every* plugin runs.
I don't want to allow a plugin to change any values that would affect
the *current* DSP cycle. The semantics of that would be unclear, and
might depend on the order in which plugins are invoked.
