How to use restartComponent and which flags are the right one, when changing all characteristics parameters except size

Hi Yvan,
Thanks for your quick response,

I do have few more questions about it:

  1. What should I expect from the host after calling restartComponent (Steinberg::Vst::kParamTitlesChanged | Steinberg::Vst::kParamValuesChanged)
    After this stage the host can continue calling to the process and automation?
  2. What function should I expect from the host after those stages, will setActive (false) will be called and only then we need to change our value,
    or before calling restartComponent?
  3. When and how do the host know about our new titles/values/flags ?

Thanks
