Just to put my 2 cents in, I make the least amount of money selling Ketron products, so selling one of them really isn't my top priority.
But I know allot of loyal Ketron users, and unfortunately to me, they are still using their MS40, SD1s, X1, from 20 years ago, they sound amazing and are still going strong, I usually get a Yamaha or Korg guy, coming in and saying it's time for me to update and get a new board, great, I might be able to make some $$ and feed my kids.
But I hardly ever get a Ketron guy to part with his equipment, they still sound good and where always slightly ahead of their time.
Their reliability to me is very impressive. you have to think about it, does anyone ever start a thread with, " Damn it, another day and my instrument is working fine "
I do admit, Ketron needs to get those OS updates out to some beta testers before releasing, but being such a small company, they already are understaffed, and take forever to release a product, so I believe they feel the product is ready but sometimes the power users will find bugs where they don't
