... I am assuming it's because I don't have some RealTracks/Drums that are required for various styles...
I don't think that sounds right. The Stylepicker isn't smart enough to know if you have all the individual components of a particular style, that you are missing certain RealTracks (or Drums). It only lists the styles that you have purchased. The assumption would be that you purchased the styles to go with the certain package you bought. We see people getting into trouble with this when they have the Pro version but purchase the Xtra Styles (without noticing the caution) and find they don't work. That seems to me different from what you are experiencing, although I could be completely wrong. You have to generate the song before you are told what is not there (although seeing N/A in the mixer is a good clue).
Thanks Matt I keep filling more and more gaps that I have with BIAB.
Well BIAB isn't as smart as I thought then (I thought it was noticing I was missing components from styles).
But it seems you might have missed something. You said: "It only lists the styles that you have purchased."
After I followed your instructions below I went into the Stylepicker and checked out the Styles numbers more carefully than before. They might have changed as a result of the updating you recommended.
But this is what it said for me under Jazz: 3281 UltraPak styles, (2219 Jazz found).
So it is noticing that I purchased the UltraPak and states the number of jazz styles in it. But it also states the Jazz styles
it found, which is less.
You asked before what I copied over, so that I don't get this kind of error. Now that I am on my computer, I can recall what I think I did. in the /bb folder, I copied all the following folders:
/Data
/Preferences
/Styles
as well as
/Drums
but only some of /RealTracks folders.
And one more thing: I copied all the individual files in the /bb folder itself.
Let me know if what you did is the same.
.
And now I have some really good news!
After following your instructions, the biggest being copying all the RealDrums onto my drive,
my StylesList has grown markedly. I can now see tons of Bebop styles whereas before none were listed!
I already had the /Data/, /Preferences/, and /Styles folders installed.
And my /bb folder was also up to date.
So basically I just installed several Gigs of RealDrums.
But that seemed to make the difference, strangely enough.
But here's a real kicker. Remember that thread I started lamenting that my mMaj7 chords weren't playing?
For some strange reason they are playing now!

And you gave one more important instruction to me that I hadn't been doing as a rule.
I wasn't regenerating after choosing a new style.
