At first: I don't speak/write English well but I try
I have a MIDI Keyboard which I bought in 1995.
(It's a General MIDI Keyboard)
I have sound on board (AVANCE 97)
My Keyboard is connected to the gameport.
In the BIOS I have activated MIDI support.
But the keyboard can only receive signals.
It doesn't send any signal to the computer, I think.
(I have also chosen the same MIDI channels in the Reason Preferences and on my old Keyboard)
