Hello MikeF
I don’t have either keyboard, but have downloaded the manuals, (I presume pf2 was a misspell as I can only find a fp2) and the Roland will only output on 1 channel at a time, the default being 1, which means if both keyboards are set at the manufacture default settings, when you connect the Midi Out of the fp2 to the Kn, the fp2 will play whatever is selected for the right hand on the Kn, if you wish to use other parts of the Kn then look in the Technics manual to see what channel you have to set the fp2.
Hope this helps.
Bill
