oops, totally forgot to answer the question:
Im not sure how to do it, but yes, there IS a way to map different CC's to different values in your VST. it all depends on whether the VST supports the language or not. 99% of the time they do. In theory, any of the values that you see in software can be assigned to a CC number accordingly to your UC-33 unit, but personally for me, it was too time consuming to dig deeper into it. You might have to not only look at the different CC charts of your UC-33, but also at the chart for the VST you are using, and figuring out how to link one with the other. I hate technology!
