Pumps,
Something you might like to play around with is saving Realcharts as midi. This is found under "Prefs | Realtracks".

I haven't played with this before. After activating it, I loaded a song file that had a number of Realcharts associated with the various tracks, generated the song and saved it as a midi. The generated tracks that had Realcharts saved in the midi.
The below pdf lists all the Realtracks. I've sorted it by Set # so that you can see the latest sets. (Because the file is 18 megabytes, it might pay to right-click on it and save it to your hard drive - rather than left-click to open it.)
2016 Realtrack list showing Realcharts (18 MB)Version 2016 introduced Sets 228 - 253. I've highlighted these yellow. If you look down the "Charts" column (highlighted pink), any RT that has Gt or N has Realcharts associated it. It seems to me that there are a large number of new tracks that have Reaclcharts.
With the above "Save Realcharts to midi" option on, it looks like 2016 could be useful for you.
Hope this helps,
Noel
