Just upgraded to X1 from 8.5 and I LOVE the new interface.... it's like Cakewalk read my mind and created an interface that makes complete sense to me.
That being said, I did run into a HUGE problem with Dimension Pro. Probably something I did wrong, but after following the bouncing ball and upgrading to X1 and then upgrading my existing Dimension Pro (1.2) to Dimension Pro to 1.5 (64bit) any project created in 8.5 that had an instance of Dimension Pro (1.2) gives an error about not being able to find Dimension Pro and basically "greys out" the incidence it. Shouldn't be a problem because I can just insert an instance of Dimension Pro 1.5, BUT... I never renamed the tracks with the actual name of the patch, so there is no way of knowing which patch to load in 1.5. I've learned a lesson about renaming tracks, but right now all I can do is go back to a second computer that still has 8.5 on it with Dimension Pro 1.2, open the file and make a note of what patch I used, open the file on the X1 machine and insert new instances of Dim Pro.
Aside from that, everything else seems to be working very well. And, again, I find that the interface has completely changed the game for me.... night and day.
Thanks, Cakewalk
