After i arm the track im not sure what you mean by set the input to the Nocturn?

I got my Novation Nocturn 25 today and have spent hours trying to figure it all out. Ive got all the knobs asigned to it i just cant controll operator with it. Operator is asigned to the drum pads and I want to use the actual keyboard to play notes with operator. Does anyone know how? Thanks
