I believe I had FS4 and 5 set to scroll presets, so assumed that might be how it was set up by default.
So, I set the buttons to 52 and 53 in the editor on the utility X page and now it controls FS4 and 5 and then I changed those to bank up and down in the HX and it's working. I have bank up and down buttons. Thanks for the help.
For the number values, is there a good resource, other than Disaster Area's HX recipes page and the HX manual, to find what numbers to enter for various functions, or do those represent all the possibilities?
