This good question comes up every so often. What follows is just my opinion.

As I understand it, the intent of Force Simple is to remove upper extensions. Anything higher than a 7th (like 9ths, 11ths and 13ths and flat nines, sharp elevens etc.) gets stripped out. In practice, some users feel it doesn't always become "simple enough", such as using straight 3 note triads, without even a seventh. Worse, sometimes that seventh can be dominant or major, and be the one that is the wrong choice for the song.

It appears to be highly dependent on the style or RealTrack selected. If you choose a jazz RealTrack, Force Simple may not work very well. On a folk or classical style, it should work better.

Finally, there are local and global overrides for this and we don't know what the hierarchy is.

If you find a particular style that is not responding as you need it to, and it's reproducible, one thing you could do is freeze the song to send it to support@pgmusic.com and make your case. Or go to the Styles Wshlist forum.
