I can see a use for that, Pipeline, thanks.

Bob, I believe you understand what I'm asking; the soloist who vamps on a whole note because that particular chord extension wasn't in the song used as a template. I think you are correct based on an early experience I had with RealTracks: I discovered that one piano part didn't know what a minorMajor7 chord was, so every time I wrote that chord, the piano stopped playing for that measure. After I reported it to PG Music, they released a patch and it was fixed. It could have been miscoded, or maybe there really wasn't a recording snippet of that chord type - we don't know.

This is why I originally asked about the need for a jazz template song with all the chord types.
