I believe Ketron and General Music had the excuse of being very small companies, where the staff, engineers, designers, are sometimes the same person, so to get a product out, there are a few things that probably get missed. But a company like Korg, should never have the same amount of issues when first launched, especially a product that is another version of an existing product. But that all said, the only way to truely find out whats wrong is to get it into the hands of the users, because everyone uses them differently and will find out things that others would never.
