Frank is one of the few dealers I would trust (in addition to George Kaye) to not mislead you all about something like this. If he says HIS units haven't locked up, you can be assured they haven't...

But Frank, with all the attention being payed to this on here, perhaps YOU could organize some sort of bugbase and crash reportage system to help track down this issue. I know it has GOT to be affecting your sales, this uncertainty. You might be in a unique position to mediate between the users and Ketron, and to provide somewhere for users to swap serial #'s and hardware details to help track this down...

Remember the LED light issue with Korg PA2Xpro's? Seemed a bad batch got into the production line. Maybe there's something that might be similar here, but it appears that the users themselves don't have the inclination or the skills to track this down. But, as a dealer, you stand to gain from assisting them through this process. How about it?
