Don,
I had a KMA and used it on gigs many times. I added John Smies Resources for it and it was amazing how much it improved the little monster. At the time I was using two Bose L1 compacts and wow did they really bring out the best in the KMA.
About a year ago the motherboard went south and it cost more to buy another motherboard than it did to buy a new KMA. So I did not replace it. But it sure is a good keyboard.
