Is this even music related?
If a guy wants to make a band with 20 strings (extreme exaggeration) let him do it... the end of the day if he is making music that other people wanna listen to good for him. I remember not too long ago someone made a band based on Microtones. Now I don't really much go into that but someone else on here might.
I think Max pretty much hit the nail on the head when he says that you're being far too vague.
