If you want to add modern beats you need to make it easy to do so you can drag n drop samples/loops into the track anywhere and be able to set the key/chord tempo and set it to repeat for so many bars all non destructively so they can be moved around and edited easily. The Loop dialog is so old and limited.
Then you can do it all in Biab without having to sync Biab to FL Studio or Reaper.
I remember asking for loops years back and showing drag n drop but the old Loops dialog was added and don't give much control and is a slow roundabout way of doing things. You need easy drag n drop non destructive. How it is now is like having to open so many jail doors by entering a code one after the other to do something.
See with both FL and Reaper it's all drag n drop non destructive easy editing.
