I'm not sure that's correct. The OP question's "I just want to create tracks with an acceptable tonality and to dictate the chord changes. Is BIAB what I need?"

You've replied that <"The "RealTracks" in BiaB are much better sounding that iRealPro. At AudioTrack says, they're real musicians playing real instruments. BiaB adjusts the pitch and time to match the key and tempo of the song and provided one doesn't try to stretch the tempo too far, it works superbly. Styles have optimum tempo information with them.">

I don't see anything deep about correcting that RealTracks and RealDrums can also be edited even if editing midi is easy.
