Hey Aron,
This requires some roto to cut yourself out of the video. If you have the studio version of DVR you can use the magic mask for that and it should be fairly simple. If you are running the free version, though, it’ll take a lot of time. Let me explain how this works.
The first thing you need to do is to duplicate the recording two times and put the three copies on top of each other. The bottom layer will be your drum loop, the mid layer your bass and the top layer your piano.
Next, you want to take the drum layer and make a loop for the drums. For this, you cut the clip where you want the loop to begin and end and then you simply duplicate that clip as many times as you need.
For the mid-layer, you need to start doing the rotoscoping. The idea is to isolate yourself from the rest of the background, again using the magic mask if available or doing a manual roto. If you don’t know how to do roto, you can also find someone (for example on Fiverr) to do that for you and have them deliver a matte to you. You don’t need to roto everything, just the bit where your body is still near the drums. Then you can simply cut the clip and continue it with a crop.
Then you simply loop the mid-layer as you did for the drum and you repeat the previous step for the top layer.
I know this is not the easiest to explain via text, but I hope I was clear enough!
