I am very sorry, but for me it is very difficult to explain these things because english is not my main language. Of course I could explain these things in finnish to you, but I don�t think you would understand that.



So I will start again. I have connected both keyboards to my computer with USB (one keyboard at time) and when I try to transfer or receive data, I get an error message saying that I should check my MIDI setups or something like that.
