I like the Idea with the Video RealTracks, but I could also imagine it could be extended a little, in some way. Currently it is so good, that you can learn playing a Song with the Videos which is a real great Idea!

For me, it would be great to have even more different Instruments. I am missing Instruments like Harmonica, Trumpet,... Even if that means you can't learn playing anymore from the new Videos. But to be able to have Videos generated to your Chords/Melody with this particular Instrument you are using in BiaB, to see how this Instruments are played for this Song is a great thing, what I like!
