Willy, first I'll welcome you too and nobody dislikes noob's here as long as they're respectful.
Funny, I keep fighting the urge to add Free to your name...

Anyway,

Here's the deal, you're starting with the ACW and trying to to work with an existing classic song. The ACW is pretty cool and trust me there is nothing like it on the market that I know of. It works "fairly well". The key to the ACW is the simpler the song the better, the more complex the song the worse because we're dealing with an audio file here not midi.

If you had a midi file of Sultans the program would recognize everything about it from the chords to the melody to the voicings of all the instruments but that's midi. Audio is much more difficult to work with. You're asking a dumb computer to do what even you cannot do, use your ears to transcribe difficult music from a record. Not an easy task unless you're a graduate from a big name music school. When you think of it that way you begin to realize just how amazing the ACW is even with it's flaws.

This is not Biab's primary function just like printing charts or sheet music is not it's primary function either. Biab will do lots of interesting and useful things but still what is it's primary purpose? To make good generic backing tracks for you to play along with. That's what it's name means, Band. In. A. Box. As in you get a full band to practice with. It's not designed to create cover versions of classic songs or any of that. It can be made to do that but it's very tricky and that is for advanced power users, not noob's.

You can use loops, you can record some classic song licks yourself in the audio track, you can import parts of midi files of whatever song, you can edit a Biab generated midi part (but not a Real Track, that's audio vs midi again, remember that) and then freeze the track so it won't change when you regenerate the song. All of that is tricky and takes time.

Meanwhile the program is designed for you to simply pick a style and tempo, enter some chords, hit play and start jammin. That's what the program was built for. All the rest of it is icing for experienced users.

My suggestion is learn the basics first, get a handle on how the program works then start with the advanced stuff.
