GT-1000 core, button setup?


I have to setup a GT1000 core, with three sounds basically, a clean, crunch and lead. Ideally, I'd also have three more that are the same but tuned a 1/2 step down. I have all the presets made, but not sure how I would assign them to the footswitches, can someone give some ideas?

I also have a full GT1000, but that one is a no brainer, normal tuning is one bank, 1/2 step is the next bank
Save them in the order you want them? There's an editor that works offline you could use to check or look in the manual. I am just suggesting a methodology.
The manual has very little on the footswitch assignments, its starting to look like you can't actually assign specific patches to the pedals
