you cant play very fast
and also it is a bit too much work to learn how to play your bass guitar. haha it is tough enough just memorizing and playing an ordinary bass, but now i have to learn this shit. plus there is no tabs, so it is obviously freestyle, but you would have to spend at least a coupe of hours to play anything really good. so i dunno, you should make maybe a tutorial thing, so like you play alog or something with the song, so you say "G#" or whatever abd then you have to play it, just like if you ever played "ready to rumble boxing," you have to do that in training for punching technique. i dunno but it was really creative and original. good concept i think you needed to take it a little bit further though, keep up the good work. i stil like virtual drumset better though.
