I am also still working on an FB01 panel. I can assure you: this one will need a fair amount of LUA programming. The FB01 really has a tricky SysEx implementation. For now I will be concentrating on FM patchparameter control, which can’t be done on the unit itself.
I will not show any pictures if there is nothing actually working yet. I am not like Behringer promising another xxxxx clone “soon” 😉
