Squeak,
I gigged with my KMA very often. I really like it. I would still be using it but the motherboard died and it was going to cost a fortune to replace it - more than a brand new keyboard.
I also bought John Smies resources for it and boy did that make a difference. You might contact John and see if they are still available. Tell us what kind of music you play. I might still have my KMA files and would be glad to share them with you.
