So I am thinking it is the physical keys that are having a problem
Maybe not.
Personally, I would open up the Triton and locate the ribbon cable coming off the keybed. It's easily spotted.
Then make sure it's sitting into it's socket firmly.
Wow!
That really sucks!
I'd be afraid to open up my keyboards, but I'm a big Wuss, so if you're comfortable doing that, it couldn't hurt to try Sharp's suggestion.
Good luck man.
