the issue may be caused by the fact that I was using input parameter
interpolation rather sparingly when writing plugins...  so this may be
causing problems for you. I don't automate plugin parameters very
frequently myself, so it didn't cause problems for me so far. If you
could tell me the parameters you use (most importantly the Reverb
type) and the decay range you are automating through, I will try to
reproduce the problem and see if there's an easy way of eliminating it
within the plugin. Although I'm afraid it won't be easy, because the
decay value is *the* parameter that affects all internal variables in
nonlinear ways...

A possible workaround may be to create wet mixes with different decay
parameters and crossfade between them to create the effect of varying
decay time. You may also try automating the wet level with decay time
set to a constant (larger) value, although the result of this will be
noticeably different.

Please accept my sincere apologies.
