Thanks Peter,
This is nearly all I want to know about these algos. My question, in first, was directed to a little in depth information about source reverb concept, not particular situation where, of course, I will use some which I like the most. English is not my first language and therefore my sentences have to stay simple. Because of that, some misunderstandings are possible. Sorry for little sarcasm in my last post, but the purpose of this forum is to people help each other. Nobody know all.
