as promised: here's my writeup on remapping channel numbers...disclaimer: this process is pretty long and not necessarily easy to do. it's easy for me, but i'm a programmer by day and used to dealing with this kind of stuff.
please let me know if you run into any issues and i'll do my best to help figure them out. the code is up on github, feel free to fork it and make changes / put up pull requests with any improvements.
i created a thread in the playground to keep track of any issues with this too, seemed like a better idea that intertwining it with this discussion...
