I’ll have to audition those styles to test, but you are correct about the theory.

An altered 7th chord by definition has neither a natural fifth nor a natural ninth. Likewise a + chord, an augmented chord, by definition means the fifth is raised a half step.

I’m not surprised the MIDI is more accurate. It is created by algorithm and there’s no reason for it not to be right if correctly programmed. RealTracks, though, are snippets of actual live music recordings, so there could be two common explanations. First, the performer just didn’t play that chord. Second, some index is wrong and a patch to the program is needed. I’ve had that happen and when I reported it, a patch was soon issued. So, we need to test and if it’s wrong, report it.

One self-help you should try whenever something doesn’t work correctly is Options, Preferences, Return to Factory Settings, Most. I don’t think that will help here, but it can’t hurt to try.

Very interesting first post. Welcome to the forum.
