This is very similar to my upcoming senior design project! We're making a learning tool that will allow you to write up tabs, play them back with production audio, and then play along with them. Once the play-along is complete, we'll be implementing a system for evaluating your performance accuracy using some basic numerical analysis principles. It's a big project, but we've got the entire semester ahead of us and a lot of passion behind it. If you're interested, let me know and I'll link you to the repo once we're underway.
