After replacing the mother board, continued freezes, sending AJ a Youtube demo of my MidJpro still freezing plus several problematic styles sent to AJ also freezing on 2 MidJpros he tried, I was sent a replacement MidJpro. KETRON claims the styles that froze were created for/on the SD7 Keyboard and not the MidJay pro. Don't know if I buy that explanation since my MidJay pro froze long before the Gold package was installed. So far, very happy with replacement. I'll post if I have any continued problems.
All that being said, I want to once again say how much AJ's patience, expertise and support continue to exceed expectations and how I remain a loyal and satisfied customer...
