UPDATE:

I have now tested out the newer version of Song Master Pro and was very impressed. You can simply drag a song file onto the app window and it immediately analyzes the song, sections, chords, beats, bpm, key and sets the bar and measure lines. It has all the speed and pitch controls you want. It has a feature where you can auto correct pitch with a push of a button for those recordings done in the 60s that were always out of concert pitch due to tape machine problems. The chord detection was pretty good and now with the updated program, changing the labels, chords, sections etc was a snap including color coding. The stems splitter works flawlessly and the quality seemed perfect as could be depending on the source mix. Saving the stems with the song file was easy in FLAC, OGG or WAV. And the stems were saved with appropriate names by instrument. Export could be done in any format including MP3. It does NOT export in MusicXML or MIDI. There is a chord sheet view. Full looping capabilities. And on and on. It has its own way of doing things so you do have to learn the controls, but I found that to be pretty easy. So bottom line - this program does all of that. I will now use it to do all my imported song analysis and save BIAB for just creating new fresh chord progressions with RealTracks for their sonic quality and not mess around anymore with audio import and manipulation which I feel is not reliably or easily implemented in BIAB. I thought this report might be helpful to further document my journey and experience.
