I understand styles affect the song results, but the songs, while they sound cool, sound nothing like the songs they are supposed to sound like! LOL! I would like to know how do I enter specific note values, so I can say a rest, followed by 2 1/8th notes played as a triplet, etc.
This is one of the biggest misconceptions of this program. It doesn't sound like a specific song because that's not what Biab is. Nowhere in the documentation does it say you can use Biab to create a song specific cover of whatever tune you're interested in because that's a copyright violation from the PGM's pov.
However, you can do it but you're jumping into the deep end of the power users pool right out of the box.
Without going into a 5 page detailed answer start with the styles. Biab is governed by styles and you can write a style that contains the exact or very close elements of one particular song. Understand though once you write that style it's really only good for that one song. If you use it for a different song it's going to sound like the tune it was written for but with different chords.
The next thing is freezing tracks. Working with midi only, not the RT's you can take a Biab generated bass track for example and going into the midi sequencer edit that bass track to match whatever you're looking for. Once you do that you have to remember to freeze the track otherwise as soon as you regenerate the song again Biab is going to regenerate the bass track according to the style and wipe out what you just did.
The third thing is loops. Lots of songs have repeating patterns or hooks. You can either find a loop of that or create it yourself and put into Biab's loop folder. You can assigned it to any instrument part you want. That alone is a whole other discussion.
That's enough for now, there's other power tricks available but again Biab is not designed for this. It's designed to give you good backing tracks to play along with in a style that could be "similar" to certain songs. For creating covers you're better off using Real Band which is a whole other discussion.
