Is there a sync issue on your YT video? It seems like the audio and yellow line are not moving together. I'd also consider cropping the videos beginning, better lighting, and better audio quality.
The cursor is moving at indicated tempo, I'm a bit ahead of that but whenever I hesitate it - rapidly - catches up with me. Having the cursor advance at speeds higher than indicated tempo is re-inforcing bad behavior so I have so far not implemented that, though technically it is possible.
Better lighting and better audio are noted, this was just a quick & dirty demo of the program in action with the tools at hand.
