I'm with the OP on this. Yeah, no updates sucks but I've got a great recording box going here and could be so much better if I could upgrade to X3. Now, I'm stuck on X1 and it doesn't appear to have comping for multiple tracks and I've read that X3 has a lot of great comping changes.
For me, the worst part about Cakewalk shutting down is ending sales. I don't care if the product is dead for updates.
