That explains all! Thanks! Yep, i just wanted to know if, for example, we could route the output of a filter directly in the input of another filter. For parallel puroses, the 4 filters are already in that state. The idea of using the output of a filter as a source of frequency modulation is gorgeous, only possible until now by modular systems.
Yeh the plugin-manual would be fine as a temporary reference. Whatever suits you anyway...

Thanks for the informations!
