Suppose I want to upgrade from my X1 producer Expanded to X3, because I would appreciate the improved stability. I have looked at the feature comparison between X3, X3 studio and X3 producer and see that the only things X3 producer has over the basic X3 are things I either have already (like many of the synths and the LP64 mastering plugins) or don't need (like the super advanced effects plugins).
 
If I upgrade to the basic X3, will I still be able to use the prochannel modules and vst plugins which I have paid for when I bought X1 producer expanded? Will they play nice in X3?
 
It is quite a difference in upgrade price between going to X3 or X3 producer, for stuff an ultra-low-power user such as myself will never need and the things I do use are already included in my X1 license. I would have wished for once long-time users (upgraded each step from CPA3 to X1) would get a free upgrade, even if it would only be every 3rd upgrade or so. As that will probably never happen, I will consider going to basic X3 as long as the answer to my question above can be answered affirmative.

Thanks...

X3 basic has no ProChannel, you would need at least X3 Studio to use ProChannel modules.

oh, i thought the basic did? but with no modules... is it right that if i upgrade to the basic version none of my pc mods will be available? tia :)

Only X3 Studio and Producer have the ProChannel. It is easy to tell, the Quad Curve is not part of the basic version. Quad Curve is not an optional PC module, it is built into the ProChannel. No Quad Curve, no ProChannel. No ProChannel, no place for ProChannel modules to load.

thanks for the info, i was under the impression that the extra content was the difference, not functionality

thanks for the info, will consider waiting until next summer then just before X4 probably comes out and upgrades will get cheaper. I might be able to jump to X3 studio then for the price of X3 basic now.
