The Old Guy. Haha, this whole forum is mostly old guys as in 70ish. I'm 72. There are younger folks around but alas not a whole lot at least on this forum, I don't know about the wider customer base.

Anyway to your questions. No need for mp3's as long as you have a sound system to plug the output of your computer into. NOT your Roland guitar amp. That's for guitars only, it sounds like crap if you try to play a CD through it for example. Like lots of old guys are you a stereo person, did you have a good system back in the day? You need something like that to play Biab through. A modern home theater system can work too. Or of course, powered studio monitors but that's a whole different discussion.

Do you know anything about music at all? Do you know what a chord chart is? Do you know what 1-4-5 means? Do you know what a 12 bar blues is? Do you know the difference between C7 and Cm? These questions are as basic as it gets. If your answer to these questions is no, then you really do need some musical help because you need at least that much info in order to create a new song in Biab but don't worry, those questions are pretty easy to learn. When you start a new song in Biab you're creating a chord chart (Biab calls it a chord grid, same thing) which is why you need to know those basics.
