If you mention some buttons by name, then perhaps it's easier to tell.
I use the VST 3 versions in V-Collection 5, but i believe this information is the same for VST 2.
I can tell that there are more parameter availble for automation in V-Collection 5. For MINI V all the buttons on the main GUI for example is availble for automation.
But how the parameters at the moment are availble in your DAW and your controller i can't tell.
There are for example also reports in in the forum about some button parameters that is reversed.
Perhaps you can try it out using trials.
