Hey noobie, welcome to the forum!
My first response, yes, sarcasm on, would be have you searched for the online manual to get the instructions?
Ok, sarcasm off.. I don't use that vst, but I have Addictive Drums and an audio interface.. instructions came for hookup with both products I think.. and there are a ton of youtube how to videos. Generally you use a midi cable (looks like a printer cable) and once connected to your pc/device it shows up as a midi device or plugin in your software.
Also, if I recall, your audio on the pc will get disabled even with an audio interface's driver (but not on a mac I think). I think I've mucked around with the audio settings on my pc before to somehow make it work, may have been some setting along the lines of allowing the speaker to not be completely controlled or taken over by any one audio device, but I could have been medicated and it was all a dream.
Ultimately I tend to just have another player connected to the interface to play my music or videos, or I have a small mixer that I patch my Addictive (or your Superior) out from the computer to the mixer and then my tablet or mp3 player feeds into another channel on the mixer so I can EQ the two.. its actually a lot easier to make quick volume adjustments than trying to click on the volume of youtube or my vst on a computer...esp when you have a drumstick in your hand.. volume knobs or sliders save me from deafening volume changes between different recordings way faster than reaching for a mouse or touching the screen etc
