Hello Darrin,
yes, I'm using the keyframe api and the parameter setting api for setting parameter values.
After some more testing I found that the problems are related to the context where this code is called.
I've moved this code into the effect's "parameterChanged:" method, and this seems to fix both problems.
Is it expected to work only in the "parameterChanged:" method?
