Thanks Andi - that clears that up!
The only problem is that now I've seen certain features of your soundset eg the way it handles the diff legato speeds ie vertically, I need to go back to my other edited sets to get the same things to work there! ie in the SE set if I try to use the two legato patched (normal and fast - which I have from the single instrument downloads) the vertical span idea doesn't work as it then stays on the lower vertical cell when changing to another horiz. patch!
Oh well - just need to find some time to do it - at least now I know how!
