If you hit the green arrow to play, then it will invoke a web demo (which is not the song you are currently working, just a demo song) and NO regeneration is required. If you hit the "Play" button on the lower right of the screen, then it is going to apply that style to your currently loaded song and yes, it will regenerate, because it has to read your chord progression and come up with the arrangement. BIAB starts generating and then begins playing before it has finished (unlike RealBand, which generates the entire arrangement before starting playback).

That being said, I just loaded a song and selected several different styles. I could see the generation in the background, and tried several other styles right after it started playback, with no problems. But that could be attributed to machine differences.

If you just want to hear a sample of what the style sounds like, you can select the green button at the top, instead. That will load a sample file. Be aware, though that the demo button will use your default sound card setting (for example, on my laptop, my internal card is my default, but I have BIAB set to use my FastTrack Pro. Normal BIAB playback occurs through the FastTrack, but the demo files use the laptop's internal card, because it is default).

I would suggest maybe restoring default settings, resetting your sound choices and trying again. I do know it works correctly here.

Also, keep in mind that real styles with soloists (rather than rhythm accompaniment) takes longer to generate.

And I made the assumption you are using RealStyles, as MIDI styles generate immediately with no latency.
