David Snyder, thanks for opening my eyes to all the midis freely available with all parts pretty true to the original songs. I had no idea there were so many.

There seem to be 2 choices to access these:
1.) and Ultimate Guitar Subscription - to TabPro

2.) Guitar Pro subscription

This gentleman did a review and seemed to prefer the GPro - as David suggested (though he shared a link to the Ultimate Guitar website).

With tech moving so fast - I completely missed the huge library of accurate midis available for such low cost. And imported and played in BB - that's the icing on the cake - to slice and dice them up - view and play those tracks separately, in combination, or with different volumes.

I'm actually curious to know how they got all these midis together with such accuracy. I know there are books out there that have been transcribed and are sold as "authorized transcriptions", etc. - do they actually have a tool to scan these pages in and/or just generate the midis as the transcriptions are done in Sibelius or some similar program ?

And I would bet there's something interesting going on with the copyright in that domain too lol
