I'm certainly not saying the OP couldn't use some experienced help or consultation, I just thought the message came across as 'Go away NEWB we don't want to help'. Also, it seems rather apparent your choice of "42" is related more to http://en.wikipedia.org/wiki/42_(number)#In_The_Hitchhiker.27s_Guide_to_the_Galaxy  than it is to channel ratios... While certainly amusing, it is not helpful.

Anyways, it's just a mailing list, just software, just one's and zero's. Moving along... :-)
