Brody - I see what you are trying to accomplish. Possibly you are trying the "alternate" if-then-else programming for another reason/purpose?
However, I thought the Pioneer FD-150/151 series had discrete off codes?
I have a pronto ccf file directly from Pioneer which has codes for Power Toggle, On and off. I have not investigated the actual hex to see if it is different but the ccf file came from Pioneer's site directly and they are usually quite accurate.
Want to try and paste this into NSP and see if it works natively?
