Hi all,i want to costumize me a carbon v2 skin and doing good progress but now i have some questions about the sampler. It wouldt be nice to get some answers

1) why is there a sampler1 and a sampler2 section?
and why are some commands twice in this sections?
are these "global sampler" commands?
2) is there a way to add the "key" function to the pitchselect button
to change only the key? its also shown in the sampler tutorial video
3) i know the *gen commands are there to display something (like countergen, etc.)
but what do all the other *gen commands like playgen, addgen, etc do?
and why are the "non *gen" commands in sampler1 section and the related *gen commands" in the sampler2 section?
4) why are in the sampler2 section allways two ":Sampler" lines?
5) how does exactly the modewheel command work? i dont get it working...
Of course i will upload my skin if its finnished so
thanks alot for answering my questions
