In Nuendo 7 and with RX v4 I encountered two distinct problems with at least Denoiser and Dialog Denoiser when used as inserts;
turning off the plugin (i.e. bypassing it) wouldn’t stick after having saved the project and reopened it (or reverted).
automating the bypass function by clicking on “bypass” would write automation, but I was never able to undo that automation write.
Does anyone know if this was ever solved with either Nuendo 7 / RX higher than v4, or Nuendo 8 / RX v4 (or higher)…???
