Hi Picker and welcome to the forum. You should be reading the disclaimers at the top of each forum explaining what it's for. This is the wrong forum for this question. It's a Biab question and you would get a lot more responses if this was posted in the Biab forum. Plus you need to tell us what version are you using and is it Windows or Mac? There's a Biab Windows forum and a separate Mac forum.

Anyway, Biab is controlled by styles. There are all kinds of different styles and it's the styles that control the feel. EV means even feel and SW means swing feel. Each one has dozens of styles. Using F5 as described above allows you to change the style at that bar. You can put any number of different styles in different parts of your song. You want to change styles every 2 bars? You can do that.

Now, here's where Biab gets complicated but very useful. ASSUMING you're using one of the newer versions (this is why we need the version) you can simply switch out one or more instruments being used in any given style. And that instrument can be anything so for example you're talking about switching from even to swing. You can decide to take the guitar that could be comping using swing and replacing it with a heavy metal grunge part, or a latin guitar or literally anything. AND it can be either a midi part or an RT.

When you think about that you begin to realize that even though Biab is based on styles, since we now can control EVERY SINGLE PART of any style the styles become merely suggestions. Lots of users never get into that because picking a style and hitting Play is simple and that is good enough for them but it can be so much more if you want to dig into it.

Being able to do that is the huge exception to simply switching styles. That is an advanced feature that can take some time to get your head around so I'll stop here for now and see what you think.
