I have Elements 10 is there much difference in upgrading to Elements 11. I am a basic user - though I would like to get better!!
I suppose the best way to find out might be to install the trial version …
If you’re doing EDM it may be a good update for you as Elements 11 got the side-chain feature added, which previously only the higher editions had.
Also the scale assistant is quite a nice addition if you’re not good at live playing or music theory.
