actually silenceInProducesSilenceOut was not doing anything, and that’s why it was removed (silenceInProducesSilenceOut).
But anyway I did not mean to re-introduce something like silenceInProducesSilenceOut, it’s not related I think.
Some plugins, whether or not they have a tail (so whatever a silenceInProducesSilenceOut could be) need to have their process always getting called. So those ones need an option like “AlwaysPerformAudioCallback”, but I don’t think that doing that by default for all the plugins is the right thing to do.
If an host wants to stop calling my process if there is no audio coming in and if my tail is done it’s fine for me.
