Thanks man.
I had this exact problem when the stomp came out. I had to get rid of it because i couldn't work it out and the decibel 11 guys gave me a work around that was so complicated it didn't seem worth it.
I love the form factor of the decibel 11. All the other switchers i have come across , including the stomp itself have the switches too close together. G-Lab make some good ones but are super expensive.
I've decided to get a stomp again and try this out. It is really weird that Line 6 didn't just make the snapshots on less controversial midi channels being that half of the potential numbers still have nothing mapped to them yet.
Thanks again.
