Using the DSPMIXFX with other Steinberg/ 3rd party plugins

I just received the UR-RT4 and I was wondering if it will ever be possible to use the DSP with the stock plugins and/ or 3rd party plugins and will there be an advanced version of the channel strip already installed? I like the interface, great work.

If you mean Cubase stock plugins then the answer is probably no, and the same goes for 3rd party plugins. I think the whole idea of loading extra plugins is kind of impossible with the Steinberg interfaces. For instance there is not a lot of memory on board, and the functionality of the built in plugins (like eq, reverb and amp classics) has not really changed.
