I think you could lose the beginning part with the other forms of user feedback. It kind of muddies what you're trying to say, because it sets up (from the images) that maybe you're developing a form of touchscreen, but then it turns out it's a dial. Presumably, your user base will already know about different forms of user interfaces and what tactile interfaces are, so it's not really adding anything they wouldn't know. I think you could jump right in with your situation of "Several years ago, I was approached by a musician to design.." and get right to what you're making. At most, just point out that haptic feedback is important on devices (the feedback you got from the musician does a good job of making that point, maybe expand on that?).
You're also relaying a lot of information in a short time, so it may help to put some "bullet-point" type text on the screen to highlight the features of the device as you describe them. I watched it a few times, and I didn't really get a sense of what exactly the switch does other than it's adjustible from 2-12 positions. What exactly is the feedback the user will receive? Physical clicks? Sound?
Otherwise, your production values are fine. The various shots of the device look good. It's a good choice of music and it's set low enough to not compete with your voice. The video of yourself is a bit dark, especially against the dark background, so maybe adjust the lighting in the room if you film again? But it's not critical.
