Thanks a whole lot for all this info Prof D and Ibarch. I did succed in changing tones within a zone and I guess scene. Also the split button does giver me the lower zone. Upper 1 seems to be already automatically on the screen. I can't figure out how to get upper 2 to appear though.
And alas, I can report no success in finding the mono/poly option. if anybody could tell me, with arrows, literally which buttons to press to get to that, I'd be most grateful.
When I'm on a tone (ie by scrolling to it with arrow buttons under a scene) I thought maybe that would be it. I pressed menu. It simply gives me the same options: scene edit, system effects, system, input settings, utility. enter scene edit (seems like the only likely place to get to zones and then tones?) and I get the flashing lights - oh I just used that to select the three zones ok got that at least - but anyway theree's no mono/poly option anywhere that I can see. Even under Zone Sound which would seem to be it but only offers me a Tone Color option. nothing else.
I'm sticking with it guys and I appreciate your help. If I can just get to that one mono/poly things I'll be psyched.
Thanks a lot,
Will
