That's really good what you have done.
I think you have the potential to make that into a full programmable drum/percussion vst.
You can have a pattern you put in for a pre fill A a pre fill for B,
another for a post fill for A post fill B, another for a 4 bar drum ending,
once you have the A-B-(E)nding marked it will know where to play the fills and ending, you could even have (F)ill to mark where to play a fill for bars other than pre post A-B,
you could load a wav for each drum/cymbal of a kit (maybe have a round robin with a few slightly different hit waves for each drum/cymbal/percussion)

If you do a SongForm Unfold you may need some more A-B B-A

Save patterns/kits that can be shared in this forum.

Maybe have a VSTi so you can render it ??

But hey, just how you have it now is great.

I was going to suggest have more patterns but I didn't want to push it, but you went ahead a did it,
Well done !
