Here are the standard Midi cc codes https://professionalcomposers.com/midi-cc-list/ which a lot of VSTs use as standard, however most VSTs allow user reassignment if it doesn’t suit.
I am not familiar with the Aria player but I would be surprised if you could not assign Midi cc codes, (Virtually every VST I have come across does) you may find that if you right click the control you wish to change, a list of Midi cc codes will come up for you to choose, as well as a Midi Learn function. (When Midi Learn is showing just move the control you wish to assign and it is done)
NOTE: You can also usually reassign them on the controller as well if the option is not available in the VST.
A good understanding of Midi can be found here https://www.tweakheadz.com/how_to_get_started_with_midi.html which should help you to get your head around things.
Hope this helps
