< Is there a way to tell which realdrum fills are being used in my project? >

View and audition the audio data file in the RealDrum folder for any particular RealDrum in a project.

< I understand about the part markers, etc. And also about regenerating to get a different drum pattern. But, how do I tell which fills are being used? Is there a name for each realdrum fill? if so how do I identify them? >

I'm unaware of any names for fills. As you see in the Chatgpt reply, this information is in the text files and on some if not all RealDrums, there are fills after the RealDrum audio data in WAV, wma, m4a files. Opening the audio data file in any audio editor will display these fills.

< Also, is regenerating the drum track for the entire song the only way to get different realdrum fills? Is there a way to have more control over which realdrum fills are used? >

No. There are multiple ways to get different RealDrum fills and have much more control over when, where and how they are used. Some methods are programable and others are manual. Ask if you want to know more detail and explain what you are wanting to accomplish to a drum track.

< When I have a drum fill I like for one part of the song, and drum fills I don't want for other parts of the song, I regenerate, and the fills I wanted to keep are replaced. Freezing the drum track freezes the entire track, I'm guessing it isn't possible to freeze only sections of the drum track. >

I think in newer BIAB program versions, RealDrums now have partial regeneration the same as how RealTracks have the feature. If so, partial regeneration also will do partial freezing of any of the track that's not included in the partial regeneration. preserving the fills you want to keep and not be regenerated. If not, there are multiple ways to get different RealDrum fills and have much more control over when, where and how they are used.

< Trying to get the right realdrum fills is like playing 'wack a mole' and seems counterproductive at the moment
I'd appreciate any helpful info regarding this topic. >

Lol, the same can be said for the bass player and lead guitarist in most bands. BIAB is your band so be prepared for those 'wack a mole' moments.
