If the pianist who played the Realtrack did not play any Cadd9 chords (or C3 either for that matter) then there won't be any from the pool for BB to select. It picks the next possible alternative that has as many of the notes as possible in it.

771 is Acoustic Jazz Swing piano. The Cadd9 is an unlikely chord to find under that specified genre.

1729 is a Pop Ballad piano. While there may be examples of Pop Ballad with the add9 chord in them, well, if there aren't any in the raw Realtracks recording to pick from, then there can't be any in the generated track either.

1549 is Country Swing piano. Add9 is not typically played in that genre either.

1998 is not listed in my Realtracks picker. Don't know if it is because I may not have it (supposed to have them all here) or if that isn't a typo in the post.

1610 is another Pop Piano style, same as above would apply, the Add9 chord again isn't a typical for the genre.

When I require specified chord stacks on the piano, I don't hesitate to try using one of the MIDI jazz piano styles that are more able to replicate those specified chords and then add Realtracks to substitute for other instruments such as Bass, etc. With a half decent MIDI synth, piano is one of the more realistic of MIDI sounds. Mixing the MIDI piano in with one or more Realtracks takes it up a notch in terms of realistic sound as well, yielding a sum that is greater than the parts.

Listening to the "raw" Realtrack files in your folders, you can hear every chord and note played in the pool that BB must use in order to create the Track. If you don't hear any add9 chords, BB cannot make them using that particular raw Realtrack recording. This is just the way Realtracks work.

Doesn't make sense to blanket declare being an "all RealTracks user" to me, maybe you ought to try MIDI piano in a few cases where the RealTrack can't do exactly what you need it to do.

On the other hand, none of the Piano Realtracks you mention are Jazz Realtracks, other than that one Swing example. You might choose from the Jazz piano Realtracks and see if you can find one that will work with your chosen song as well as being able to play the required chord the way you want to hear it. Octave of the 9 may be a nonissue - consider that a guitar player (and even a pianist) can elect to put that nine *anywhere* as regards the octave and it will still fill the air with the "add9" sound simply because there won't be a seventh involved. If there is a piano and a guitar playing the rhythm comp together, the 9 played on the guitar may be an octave or more lower in pitch than the one played by the pianist at the same time. But if you need to specify with Band in a Box, then you need to find Realtracks and MIDI styles that will actually play the add9 in order to do that.
