Wow this is wonderful!
Any plans to port it to android by chance?
There's and old app called CDLC Player, that hasn't been worked on for years, and is not that good - difficult to read charts on it.
This on the other hand, is gold.
Masterclass Lead 99.6%
God of Guitar 96.71% (this is my sightread of Janfilippino's chart from a stream back in august)
i hope it's a valid submission, i don't want to play this song again, even if i'd do better
