Gunnar,

Funny you mentioned the Dreaded "FREEZE" while changing patterns. This was my major concern when I had the X1, and one of the major reasons I sold it. This would happen on stage while performing and I would have to reboot (most embarrassing )it would take 4 minutes or so due to the Super Sounds loading. I thought they fixed that but I see its still happening on the new SD-1 also. This is unacceptable for a pro to go thru in a live situation. This has never happened (knock on wood) with my i3, K5, or psr9k.
