Want to 'up' my piano improv practice with a Logic reference-type project.

I'm an okay piano player. I want to improve my improv playing using my midi controller and Logic.

I created a basic drum track and I throw some chords on another track and kinda improv along with that.

Have you done anything more sophisticated or better using Logic to make the backing tracks more interesting?

Or are there other ways you've used Logic to improve your piano/improv playing??

Appreciate the input!
