weird midi problem

Well it's most likely your keyboard. For some reason it is transposing up 4 semitones.

To check your axiom 25 keyboard, Hit the two big keys at the same time. (The two transpose keys) This will let you transpose inside an octave.If the number on the screen is anything different than zero then change it back to zero. To change the value all you have to do is hit either one of the transpose buttons. The one on the right adds (+), and the one on the left substracts (-).

If you don't hit the two buttons at the same time before changing the value then they will cycle through the octaves instead of single notes so take it into account!
