When you export MIDI, there is a selection (click the Options button on the MIDI Save screen) to "Save RealCharts in MIDI Files". If that box isn't checked, then you won't get anything from RealTracks. If it is, and there is a RealChart associated with the RealTrack, it will export as MIDI.
Thanks, John. That's my BIAB lesson for today. I wasn't aware of that option under MIDI save options. I only knew of the one that I mentioned early in this thread under "Preferences | Realtracks" (that one is the global setting and can be set if one wants it on/off permanently).
One thing I noticed when I activated the "Save Realcharts" option, and tested it, was that it took around a minute or so to save the file because BIAB fully generated the song. This makes sense since the song needs to be generated to obtain the Realcharts.
