Two controller keyboards in cubase.

Wonder if anyone can advise please.
I’m using cubase v5 and wish to use two keyboards.
I use it live and want one keyboard on channel one and the second on Channel two. I’ve created a single instance of kontakt and assigned two sounds , each with different midi channels hoping that they would play independently. Alas both keyboards play the same midi channel despite being set up on different channels.

In a nut shell I want keyboard to transmit on channel 1 and keyboard 2 to transmit on channel 2 which I’ve done however cubase seems to receive only on Channel one despite kontakt being set to independant instances

Any help would be great fully received
