John, of course Roland was entered..without MIDI..this discussion would not be..

BTW: who is Riki?....Don't lose that number

...one should allow folks even my age a typing error, be fair Fran....( sorry Diki)......
Thanks Ian, I am sure many of those who do use a KMA as an add on to their yammie set up will find it convenient to play the KMA via the Yamaha. Of course they could also link the Upper sounds but then you would lose the advantage of having to keybeds at your disposal for RH sounds. But in my basic set up here explained you have the advantage of playing whichever accompaniment on the Yamaha , keeping your RH sounds on the Yammie as well, and play the extra bits for the RH on the KMA, which is not too bad really once you get the hang of it.
By the way this works equally well with any Korg- Yamaha combination. At present I have my PSR on top of the PA800 and I only play accompaniment by using the PA800 keybed.........
regards,
John
