Band-in-a-Box will let you read and edit any type file you input into it. It is a matter of displaying the music you input wheather it be single line or multi-lini piano. You just need to set the chanel in questinon to guitar and display tabs for that chanel. By displaying the guitar fret board, all the tabs (icons) at the bottom left and bottm center of the fret board have to do with editing the tabs. Let's say you're using piano mode that is set to guitar, and you manually input a guitar chord. The notes plus the tab will be displayed on the screen. What you have to do is move the numbers on the tab screen to match the position you have the fingers of your left hand (right hand, if you're left handed) on the guitar. There are multiple threads here on this forum on how do this. Just use the search engine provide by BB in this forum. Hope this helps. It's a great program, just takes a little patience.
