First of all I would like to thank all of the people above for the useful and insightful input to my question. To be honest, this is somewhat out of my league, at the moment, and the initial scope of the question was a mere boardpatch, as pointed out above. I will keep monitoring this thread though, so any interesting input one feels necessary to add - I thank any and all of you in advance.
I will attempt a board recording within a month or so, solo acoustic show, so I guess the omission from a matrix set is not that grave !?!?
Still, when I have read up on the topic here on the forum and from other sources, I may come back with a question regarding matrix set ups.
Again, thank's alot for all the input, and please, do not hesitate to keep it coming if there is more.
