As a USA Ketron owner, I find this rather unsettling. I am so greatful to have access to AJ's Ajamsonic support. I think that AJ is as frustrated with Ketron as we are. I have not even tried to contact Ketron Italy because of the bad PR that Ketron has received by many Synth Zone members.
My only contact with Ketron is thru AJ. I get the impression that Ketron almost does it's best to ignore AJ as well. He has, single handedly, done so much to make Ketron one of the best keyboards in the world.
Let's not forget about Tonewheel Dude. Awesome resource for Ketron support.
