I just sort of read through that manual. It seems to me it would be easier to just put the text files in the Korg, associate the correct song with the Songbook entry and save all that trouble. I assign text-down to one of the assignable buttons. Only thing I can see that the tablet would add would be larger display and print.
Oh, it just hit me--I guess if you want to display scores that would be a valid reason to use the tablet! Duhh!
Yes, Don ... the ability to read scores and the larger display are a BIG advantage, PLUS, one could have a number of 'Fake' books resident in the tablet for easy access to requests for songs not in the Songbook ...
AND I was able to follow the KORG manual instructions pretty easily - but actually performing the steps might be a different story ...
