I have BIAB 2022 build 923 (I think that's right).
And I have installed the All XPro Styles Bundle, and the 2022 49-Pak.
I think my real question is why do I see RealTracks available for selection that are lacking the actual audio file?
1: BiaB 2022 build 923 is the latest version, but (separate to the add-ons you mentioned) that does not provide enough information to know what baseline product "pak" you purchased. When you first ordered BiaB, you had a choice of Pro, Mega, Ultra, Ultra+, Audiophile. The purchase price ranges from $129 to $669. Which one of those did you purchase?
2:
Do the RealTracks show as
N/A in the RealTracks picker, and/or the StylePicker? or only after you try to use them?
Separately, there's not one single piece of audio for RealTracks. They are made up of multiple different audio samples that are 'stitched' together by the program to provide the audio output that you hear. E.g. folder:
bb\RealTracks\Guitar, Electric, Rhythm NashvilleShuffleGritBrent Sw 110
contains 40 separate items that the program individually selects based on tempo, key signature etc to generate an audio output. Hope this is not confusing, but it may help to understand how the audio is created.
