The SC* plugins do the same as TAP (calculate the gain every 4 samples),
but I interpolate the gain values between each computation. The
attch/deacay times were slow enough in my testing that it was OK to do
that.
It would be trivial to change the plugins to caclulate every sample, but
at the time they were first released it made the plugin too expensive to
run many at once. Things may be better on current CPUs.
