Bill, one thought is to use the KMA as a sound module with styles and some really great sounds. Your left hand on the Kn7 triggers off the left hand of the KMA --- alla, something new. On the right hand you set up to Chanel/track 5 and the KMA to receive sound on the same Channel/track.

I used a 61 note Midi controller with my Kn7 – both instruments were set on the same channel/track so whatever my Kn7 selected in the 5th Channel/track would sound from the midi controller.

Back in the late 80’s I would midi my guitar; it was equipped with midi, to my keyboard. I was able to sing and strum my guitar and the keyboard followed.
Bill, move away from the OS and find a different use for your KMA it is a good keyboard; you will only be limited by your imagination. Think freely. I did that with my wife and almost got killed. (Grin)

Take care my friend, John C.
