gah, silly me.
you know when you look at something for so long you can not find what you are looking for.
anyhow, what i was looking for was pretty much right in front of me, but after making some food and having a break and some ghost in the shell, it just hit me. was a simple change of 7 to 15.
there still some minor noise, but none the less, 16 channels through one analog. now to expand it to 4 more channels with 16 for each.
