You should be fine. The TT Studies are written for firmware 1.0, but I’m pretty sure that nothing was broken.

The major meta difference is that it was originally encouraged to use A, B, C, D for triggers instead of 1, 2, 3, 4 (the original panel reflected this). Now, it’s more “standard” to use 1, 2, 3, 4 for both (the current panel reflects this). Regardless, by default, A = 1, B = 2, C = 3, and D = 4, so the old method still works. The pitfall is that you can replace the values of A-D. So, whenever you see something like TR A, just replace it with TR 1
