Budget Theremin changing sounds

hi folks, I had a viewer request a walkthrough on how to access the different sounds on the AliExpress Theremin. I know that's not the official brand but they tend to sell 20 of the same product with a different oddly spelled brand on each. I haven't screwed around with too many of the other controls or settings yet except to extend the note range lower. this thing can make some seriously deep tones. I tried to get a close up shot of the theremin screen but bringing the camera any closer actually affected the motion needed for playing this device! if you have any questions leave them in the comments!
