Bluezplayer, very good description of this subject.

For those that may be interest in my system could do a search on this forum for flr2003 or flr2004. This saves re-posting this information.

I still maintain that my system sounds better than any hardware based system and is suitable for live performances. Yes, it is true that the control surface is not as good as hardware based systems - but it is good enough - you get used to it.
