Hey – I’m new to BIAB but I know how to use Logic Pro, so I’m not a complete Duffus. I installed 2025 BIAB yesterday on my Mac but I cannot seem to select certain instruments (Guitar RealTracks).

On the right side of my screen I see a mixer. Bass, Piano, and Drums are highlighted in yellow text while everything else is in white. I can’t seem to find RealTracks for guitar, although I have confirmed that they are downloaded and in the right place.

I’m being prompted to open the Style Picker and press the Rebuild button, but I can’t find that button anywhere. ChatGPT is pretty useless, pointing me to drop downs and buttons that don’t exist. YouTube videos are no help. So where on earth is the Rebuild button, and if I press it, will that make the Real Tracks available.

Thanks for your help and patience. Sorry if this question has been asked before.
