Dynamic Load/Unload blocs (can solve latency problem between presets)

Not really. It’s a behavior inside a preset with a new type of bloc. What I want is a bloc than can be any bloc and you can choose on the fly which one you want.
Ex :
You have a dynamic bloc empty, and you want to load a chorus, use it for a while, and when you’re done change to load a tremolo for example. We don’t need all time all bloc, but it have to be instantiate on your preset. Why don’t have possibility to load it only when you want it
