EXS 24 Logic Sampler Users Group

Well I've made some trials of the "Select by : Group" Option. Had'nt 
really time to go deeper on there. I've almost understood, but use 
seems tricky (for me at least ! ;-), and it doesn't seem to answer my 
problem :

There are two groups of notes (or zones but I have actually one zone by 
note) dispached on the keyboard.
When playing a note of one group it must not be possible to play a note 
of the other group at the same time (but still possible to play a note 
of the same group) ; and the same is for the two groups. I imagine it 
has something to see with "Voices" and perheaps "Selected by" 
parameters but I can't find the way to built that "super hi-hat".

If some of you are curious (and time free ! ) enough for what is 
perheaps a kind of challenge … ;-)
(and if any solution ?)
