Midi Keyboard Question

[KS2]

Ok, so I have a 25 key midi keyboard and a soft synth with a shed load of keys. At the moment the midi keyboard only controls the middle section of keys on the synth. How can I change this? Midi learn doesn't work for keys.

If it's any use it's an Axiom 25 with D16 Lush 101 soft synth.

Your keyboard should have octave switch keys. Use those to access other sections.
