Cantabile 4 and rack states

Hi all,
I finally tried cantabile 4 (performer and latest stable version as of today). Mostly everything works as expected except rack states.

I loaded a rack that I previously created with C3. While I could see all the states, all the states became the same plugin sound as the new state that I have added in c4. The plugin is Arturia OBxa (latest version upgraded today) and I was using the VST3 version.
Is anything changed in the rack management between C3 and C4? Should I stick to VST2 version of plugins?
Anyone had similar experiences.
Let me know.

Hi Marco,

I found no differences in racks state switching to Cantabile 4. Try to use the VST2 plugin.

Hi Paolo,
Thanks for the suggestion.
