Hello everyone, there is a feature in REAPER that automatically switches off plug-ins to save processing power if the plug-in has no audio signal and the GUI is closed, i.e. not visible. You can find this feature under Project Settings > Advanced > Auto-bypass FX that reports tail length or have auto-tail, threshold: -100 dB. This feature is very useful if you want to use a lot of CPU-intensive plugins, such as CLA MixHub, in the project. I would be happy if you could add this feature to all ( CPU-intensive ) plugins.
